    Machine learning in survival analysis

    baikjaewook | 2022, 7(1) | pp.1~8 | number of Cited : 0
    Abstract
    We investigated various types of machine learning methods that can be applied to censored data. Exploratory data analysis reveals the distribution of each feature, relationships among features. Next, classification problem has been set up where the dependent variable is death_event while the rest of the features are independent variables. After applying various machine learning methods to the data, it has been found that just like many other reports from the artificial intelligence arena random forest performs better than logistic regression. But recently well performed artificial neural network and gradient boost do not perform as expected due to the lack of data. Finally Kaplan-Meier and Cox proportional hazard model have been employed to explore the relationship of the dependent variable (t_i, δ_i) with the independent variables. Also random forest which is used in machine learning has been applied to the survival analysis with censored data.

    Lee-JongHyeon , Sang-Hyeon Park | 2022, 7(1) | pp.9~15 | number of Cited : 0
    Abstract
    This study tried to analyze the growth background of Starbucks, a competitive company in the Korean coffee industry. Therefore, by using the STEEP analysis technique, each company's competitiveness was analyzed and the results were used to derive competitive factors. And the research results are as follows. Looking at the social aspect, economic activity has been a catalyst for women as the standard of living has increased due to economic growth. In addition, in the case of coffee culture in the past, Starbucks' response strategy, which has seen the transformation from vending machine mixed coffee culture to a consumer market that emphasizes cultural and spatial aspects, was effective. Looking at the technical aspect, the deviation has been reduced by securing uniform standardization of the taste of coffee beans at franchise stores, and the operation of a standardized operating system was possible by operating the store directly. And looking at the economic aspect, as the coffee consumption market continues to expand, the overall size of the market has also grown proportionally, creating a stable growth environment. Lastly, looking at the environmental and policy aspects, it is that the marketing strategy direction based on the policy activities as an eco-friendly company as a market leader has been the main focus of the recent policy direction emphasizing eco-friendliness.

    A study on the correlation between resilience and psychological well-being of adult attachment types of daycare center parents

    shin,dong-yul , Shin Soo won | 2022, 7(1) | pp.17~23 | number of Cited : 0
    Abstract
    The purpose of this study is to verify the relationship between parents' adult attachment, resilience, and psychological well-being, as it is inferred that infants and toddlers attending daycare centers will be directly or indirectly affected by their parents' adult attachment type. For this study, a total of 247 copies of the SPSS 12.0 statistical program were used for analysis, except for 43 copies where data were omitted after a questionnaire was conducted on 300 parents (150 parents and 150 mothers) of daycare centers located in Gyeonggi Province. Looking at the results of this study, first, it was confirmed that the general characteristics of parental adult attachment, self-recovery elasticity, and psychological well-being stimulate normality statistically. Second, the relationship between adult attachment and self-recovery elasticity was verified as a negative relationship, and it was confirmed that it had a significant effect. Third, it was confirmed that the relationship between adult attachment and psychological well-being was verified as a negative relationship and had a significant effect. As a follow-up study, we propose a phenomenological study of the mediating effect of psychological well-being on the influence of parents' adult attachment on self-recovery elasticity, parental attachment, resilience, and psychological well-being with infants and toddlers.

    A Study on the Establishment and Expanding the Concept of SHIPSONG in Myeonglee

    Nam-Yeon Lee , Ki-Seung Kim | 2022, 7(1) | pp.25~34 | number of Cited : 0
    Abstract
    The purpose of this paper was to confirm the source of Shipsong called Yookchen or Yooksheen used in Myeongleehak and the meaning of Shipsong in major classics. It is to investigate the concept of Shipsong used in modern Myeongri, and to study in-depth the concept of Shipsong in a more advanced form, not just in family relationships. In reality, the concept of Yookchen was defined and the term Yookchen was first used in Yeonhaejapyeong. Most of the contents of the major classics, such as Yeonhaejapyeong, Sammyeontonghwe, and Japyeonjinjeong, were limited to setting only family concepts. Then, in 1963, Sajoojeongsul was published, which explained both family relations and the action of Shipsong. In particular, it is noteworthy that the scientific reputation written by Ki-seung Kim did not only explain the concept of Shipsong but also opened a new chapter to confirm human psychology and aptitude. In this study, I tried to find out the concept and tendency of Shipsong described in Kim Ki-seung's Science Myeongri in the major classics and how the concept changed. I hope this study will be of some help to the study of Myeongleehak in the future in terms of understanding and utilization of Shipsong.

    Won-Ho Choi , Ki-Seung Kim | 2022, 7(1) | pp.59~74 | number of Cited : 0
    Abstract
    There are three main ways to interpret Zhouyi(周易). The first is to interpret it as a number, the second is to interpret it as an image symbolized by the Gwae(卦), and the third is to interpret it as the moral reason contained in it. Although YulRyeo(律呂) is not as widely known as Zhouyi, its use in ancient times was the same as that of the main character. First, the mathematical analysis method using the three-pronged method for tuning musical instruments, second, the symbolic interpretation using the musical meaning symbolized by YulRyeo, and third, the applied interpretation method that expands to the moral reason contained in YulRyeo. The purpose of this thesis is to organize the dictionary meaning of YulRyeo and various meanings of ancient YulRyeo. In addition, by studying ancient literature on the meaning of YulRyeo's magic spell mechanics(術數易學) and Naepeum and Five Elements(納音五行), which is the origin of Gobeop Myongriology, I classify and interpret them in detail. and to find ways to apply it to Myongriology. It is hoped that this study will give a more in-depth understanding of YulRyeo and will be of little help to related studies such as the mechanics of magic and Myongriology studies in the future.

    A Study on Comparison of Later Commentaries about Kyeokguk theory of Jeokcheonsu

    Bo-young Yi , Ki-Seung Kim | 2022, 7(1) | pp.81~87 | number of Cited : 0
    Abstract
    This study used a method of comparing and analyzing various editions of Jeokcheonsu, and aims to confirm why different views have arisen on commentaries that differ according to the perspective of one original text, which interpretation is more valid among them. The biggest part of the misunderstanding of Myeongri theory in Jeokcheonsu is Kyeokguk theory. Jeokcheonsu does not set a high value on Kyeokguk, and it is highly regarded as the Myeongri classics that emphasizes Eokbuyongsin. However, as a result of classifying the original text by theory, we can see there are about 5 sentences that directly mention Eokbu theory, but 9 sentences that explain Kyeokguk theory and 15 sentences if we include the sentences that explain Jonggyeok and Hwagyeok. Even looking that metaphoric speech is mainly used, it is also clear that it’s not a book written to be read by a beginner of Myeongri. This is Myeongri texts written to convey more profound logic and enlightenment to a person who has sufficient knowledge by having learned the principle of Myeongri. A single sentence of ‘Jaegwaninsubunpyeonjeong Gyeomronsiksanggyeokgukjeong’ would have been sufficient to explain the Kyeokguk theory, because it’s written on the assumption of the reader’s level. Among the later commentaries about the theory of Myeongri contained in Jeokcheosu, 4 persons’commentaries on the original text of ‘Palkyeok’, ‘Gwansal’, Sangkwan’, ‘Wolryeong’, ‘Saengsi’, ‘Cheongtak’ related to Kyeokguk theory was compared and analyzed.

    Bo-young Yi | 2022, 7(1) | pp.89~93 | number of Cited : 0
    Abstract
    This study used a method of comparing and analyzing various editions of Jeokcheonsu, and aims to confirm why different views have arisen on commentaries that differ according to the perspective of one original text, which interpretation is more valid among them. It is not easy to grasp the theories of Myeongri because Jeokcheonsu is composed of the sentences of Si-bu with being well refined and having hidden meaning. Various perspectives makes the people more confused in reading commentaries. Lim Cheol-cho make additional annotations and try to subdivide the contents of Jeokcheonsu and classify them with quoting lots of 512 exemplifications in Ming Dynasty, and it is his great contribution to the Myeongri theory. The perspective that ‘Eokbu Theory’ is core contents of Myeongri theory in the first half of Jeokcheonsu is predominate. The sentence that ‘Eokbu Theory’ is mentioned for the first time is ‘Cheayong, and we can quote ‘Jeongsin’, ‘Soewang’ and ‘Junghwa’ as a sentence paired together.‘Eokbu Theory’ of Jeokcheonsu is discussed continuously in the ‘Gangyou’ ‘Junggwa’ of Myeongri particulars which is connected in the middle of Jeokcheonsu.
