프로그래밍 언어를 위한 컴파일러를 작성하는 일은 그 규모가 매우 크고 복잡해서 많은 시간과 노력이 요구된다. 이런 이유로 컴파일러를 자동화하기 위한 연구가 수행되었으며 그 결과 컴파일러의 전반부(frond-end)는 문법 표현(grammar description)으로 부터 파서를 생성할 수 있는 파서 제작 시스템(parser generating system)을 이용하여 반자동으로 구성할 수 있게 되었다. 그러나 각 PGS 시스템이 서로 다른 문법 표현을 사용할 뿐만 아니라 정의된 문법을 각 시스템의 표기대로 나타내기가 어려워 컴파일러 작성자가 파서 제작 시스템을 사용하는 데 많은 불편과 노력이 있었다. 이런 이유로 본 연구에서는 형식 언어 이론(formal language theory)으로 부터 문법의 정의와 유사한 문법 표현 언어(grammar description language:GDL)를 설계하고 이 문법 표현을 입력으로 받아 자동으로 해당 파서 제작 시스템의 입력 형태를 생성하는 문법 표현 언어 번역기 시스템(grammar description language translator system:GDLTS)를 구성하였다. 그렇게 함으로써 컴파일러를 작성하는 사람들이 각 파서 제작 시스템의 표현법을 일일이 고려하지 않고도 정의된 문법만 기술하면 파서를 자동으로 얻을 수 있게 하였고, 파서의 출력으로 효율적인 AST(abstract syntax tree)를 자동으로 생성하여 줌으로써 코드 생성 단계에서 용이하게 코드를 생성하게 하였다.

The present study was conducted to predict the probability of defection from the membership in the monthly members of a fitness club by segmenting them into defector customers and maintainers. Through this process, it attempted to provide a basis for more successful management of potential defection, by introducing data mining. A dicision tree analysis (C 5.0 of SPSS Clementine), a data mining tool, was the statistical analysis technique used in the segmentation of the sports club customers based on their membership defection in order to predict the possibility. The result of this study is as follows: First, as a result of analyzing the segmentation variables affection the membership defection of the customers, it turned out that age was an important variable constituting the parent node; job and frequency of using the sibling node, and; consumer complaint behavior, usage frequency, word-of-mouth marketing intention, and job the children node. Second, as a result of analyzing the possibility of existing customers to defection their membership, using the segmentation variables that affect the withdrawal or keeping of membership, it was revealed that the variables were capable of highly exact prediction: 88.62% of the maintainers and 78.03% of the defections. Therefore, it was judged that the predictive power of the segmentation variable was fairly potent. Third, the analysis of the reliability of the presumed rate of defection prediction demonstrated its high reliability : defection-based decision tree structure recorded a reliability higher than 0.667. Fourth, the defection analysis model was tested using the testing data to clarify the validity of the model predicting the probability of membership defection. Specifically, the two structures of decision tree of both model designing and model testing data were compared by the method of data partition. As a result, it was shown that there was no perfect agreement between them, though agreement indeed exited just in the fact that age constituted the parent node, and job the sibling node. Even if the order or intensity of the nodes might have been different, the nodes with high purity had much to be shared. In addition, age, job, usage type, facility satisfaction, consumer complaint behavior, usage frequency, and word-of mouth marketing intention still remained as crucial factors. Fifth, the rate of defection prediction using the testing data was very high - it predicted 85.35% of all the maintainers and 69.97% of all the defections - , though it was still slightly lower than that demonstrated in the crossed matrixes of the model designing data. Collectively, the above-mentioned findings suggested that age, job, usage type and consumer complaint behavior were the important segmentation variables that affected the defection of the members of a fitness club, and that the rate of prediction based on these variables were very high. In particular, data partition appeared to be remarkably reliable and valid in analyzing and predicting the membership defection. And C5.0 was found to be more effective than Neural Networks, logistic regression analysis or CART in the final stage of developing the fitness club membership defection prediction. Applying these prediction models to customer management and business strategy, fitness club management or decision makers will be able to maximize the effects of customer-relations marketing. Customer segmentation using the existing customer information would make it possible to figure out the characteristics of those who discontinue their membership. Finally, data mining is necessary in orienting the marketing strategies and activities in the sports consumer market so that they satisfy the actual needs of the market. In this connection, it is confirmed that data mining could be introduced to this market as part of the customer retention marketing efforts.

헤르만 바빙크의 교회의 보편성 연구

박진기(Jin Gi Park) 고신대학교 개혁주의학술원 2022 갱신과 부흥 Vol.29 No.-

이 논문은 19세기 신칼빈주의 운동의 중추적인 역할을 감당했던 개혁파 교의학자 헤르만 바빙크(Herman Bavicnk, 1854-1921)가 제시하는 ‘교회의 보편성’ 개념을 바르게 이해하고, 그 이해에 기초하여 오늘날 한국교회가 겪고 있는 교회론적인 문제에 대한 해법을 모색한다. 헤르만 바빙크는 1834년 네덜란드에서 일어난 분리(Afscheiding)운동의 중심이 된 가정에서 태어나 평생 동안 그 전통을 지키려고 노력했던 사람이다. 하지만 그는 단지 분리측 사람으로만 머물지 않았고 1887년 일어난 애통(Doleantie)운동 이후에 아브라함 카이퍼(Abraham Kuyper, 1837-1920)와 더불어 교회 연합을 위해 힘썼다. 이처럼 바빙크가 교회 연합에 대한 열망을 가지고 그 최전선에서 분투할 수 있었던 까닭은 바로 기독교의 보편성(우주성)에 기초한 교회의 보편성에 대한 그의 믿음 때문이었다. 이 주제에 관한 그의 이해는 『기독교와 교회의 보편성』과 『개혁교의학』에서 깊이 있게 드러나는데, 본 논문에서는 그가 제시하는 교회의 보편성 개념을 밀도있게 연구하고 그것이 종교개혁자들이 말하는 비가시적 교회 사상을 잘 계승하고 있으며 또한 신칼빈주의에서 주목하는 유기체적 교회 사상과도 적절하게 연결된다고 평가한다. 그리고 결론으로서 교회의 보편성에 관한 바빙크의 이해가 한국 교회에 주는 교훈이 무엇인지를 고찰하는데, 오늘날 한국교회가 겪는 교회론적인 문제의 핵심에 교회의 보편성에 대한 무지가 있다고 판단하고 초대형교회들이 만들어낸 시스템과 프로그램을 무비판적으로 모방하는 획일화를 넘어서 한국 교회가 다양성 속에 있는 통일성(unity in diversity)안에서 참된 교회의 보편성을 추구할 것은 제안한다. This article studies the concept of ‘the Catholicity of the Church’ presented by Herman Bavicnk(1854-1921), a Reformed dogmatician who played a important role in the Neo-Calvinism movement in the 19th century. Moreover, it examines and finds a solution to the ecclesiological problems facing the Korean Church today. Herman Bavinck was born into a family which became the center of the Afscheiding movement in the Netherlands in 1834, and throughout his life tried to preserve that tradition. However, he did not stay only as a separatist but worked for unity of the Church with Abraham Kuyper(1837-1920) after the Doleantie movement in 1887. The reason Bavinck was able to fight at the forefront with such aspiration for the Church’s unity was because of his belief in the Catholicity of the Church based on the Catholicity(universality) of Christianity. His understanding of this subject is revealed in depth in The Catholicity of the Christianity and the Church and Reformed Dogmatics. This article evaluates that Bavicnk’s concept of the Catholicity of the Church succeeds the Reformers’ invisible church idea very well, and also evaluates that it is properly connected with the Neo-Calvinist s organic form of visible church. And as a conclusion, it examines what lessons Bavinck s understanding of the Catholicity gives to the Korean Church. It suggests that the Korean Church pursue the true Catholicity of the Church in unity in diversity beyond the uniformity caused by uncritical imitating Mega Churches’ systems and programs.

  It has long been known that obesity is one of the most common chronic diseases and a major public health problem Obesity occurred to accumulate excess of fat tissue. A lot of studies have shown that fat tissue is not a simple energy storage organ, but exerts important endocrine. It include proteins involved in the regulation of energy balance, lipid and glucose metabolism.<BR>  Particularly abdominal visceral fat accumulation, is the most common risk factor of diabetes mellitus, dyslipidemia and atherosclerotic vascular diseases. Recently, it has been shown that adipocytokines secrete several proteins including tumour necrosis factor-α, interleukin-6, resistin, and adiponectin etc. The effects of adipocytokines on vascular function, immune regulation and adipocyte metabolism makes them key players in the pathogenesis of metabolic syndrome, a cluster of clinical symptoms including obesity, insulin resistance. In addition, various studies have shown that related between exercise and adipocytokines and reported not only positive effect but also negative effect by exercise. But lots of exercise studies have shown that moderate-intensity training is more effective in improving than low or high-intensity training to adipocytokine. Therefore, these studies suggest that change in adipocytokines are influenced by exercise. Further studies are required to discover the new adipocytokine and to investigate the causal relationship between exercise and change in adipocytokines levels.

The purpose of this study was to empirically analyze the relationship between exercise commitment and exercise addiction, as well as mental health, subjecting fitness club users. In order to achieve this purpose, a questionnaire was distributed to and collected from fitness club users in city P; a total of 261 copies were used in the actual analysis. The analysis for empirical study consisted of frequency analysis, reliability analysis, and exploratory factor analysis using SPSS 20.0, and confirmatory factor analysis and structure equation model analysis using LISREL8.5. Based on the summary of the results derived from the analysis, the implications of this study are as follows. First of all, it showed that the exercise commitment of fitness club users have statically (+) significant impact on exercise addiction. Second, it showed that the exercise commitment of fitness club users have statically (-) significant impact on mental health. Third, it showed that the exercise commitment of fitness club users have significant impact on mental health. To sum up, the exercise commitment of fitness club users plays a positive role in resolving mental health issues but excessive exercise commitment leads to exercise addiction, and such addiction can become a factor to wake mental health issues; thus, it is thought that fitness club users should perform a clear and appropriate level of exercise in order to clearly understand the purpose of their participation and obtain the effects of exercise suitable for their purpose.
