이근철,최성훈,Lee, Geun-Cheol,Choi, Seong-Hoon 한국시뮬레이션학회 2011 한국시뮬레이션학회 논문지 Vol.20 No.3

In this study, we consider a capacity planning problem where the number of machines at each workstation is determined in manufacturing systems of top-edge electronic products such as semiconductor or display. The considered manufacturing system is the typical hybrid flowshop which has identical parallel machines at each workstation and the setup operation occurs when the types of consecutively processed products are different. The objective of the problem is finding good combinations of the numbers of machines at all workstations, under the given capital amount for purchasing machines. Various heuristic methods for determining the numbers of machines at workstations are proposed and the performances were tested through a series of computational experiments. In the study, a simulation model has been developed in order to simulate the considered manufacturing system with dynamic orders and complex process. The simulation model is also used for conducting the computational comparison test among various proposed methods.

In this study, we consider a capacity planning problem of reentrant hybrid flowshops. High-tech electronic products such as semiconductor or TFT-LCD, are produced from manufacturing systems which can be considered as reentrant hybrid flowshops. In the considered capacity planning problem, we determine the number of machines at each stage in the manufacturing system. We introduce criteria indicating which stage needs additional machines or which stage needs reduction of machines considering the characteristics of the product types and the manufacturing system. The objective function of the problem is maximizing throughput rate of the system, of which values are obtained from the simulation model depicting the hybrid flowshops. The performance of the proposed methods were evaluated through a series of computational experiments. The simulation model was also used for conducting the comparison experiments among the proposed method and benchmarks.

Purpose: The purpose of this study was to develop a stress test for students in physical education high schools and to verify the validity of the developed test. Methods: To develop the test, this study referred to the stress factors of students in physical education high schools, analyzed by Lee, Dong & Lee(2009) and designed a preliminary test with 42 questions of 7 factors. On the basis of the data of 544 students in three physical education high schools, this study conducted exploratory and confirmatory factor analyses to examine the structure and goodness-of-fit of the data, and performed reliability analysis. To verify the convergent validity of the confirmed test, it used the data of 82 students in one physical education high school. Lastly, based on the data of 626 students, it conducted factor invariance test and latent means analysis to investigate the difference between background variables. Results: It was found that the stress test for students in physical education high schools had the structure of four factors: athletic stress, conflict with teammates, coach stress, and life stress. According to the comparison between the test and other tests in terms of convergent validity, the developed test explained construct well. Factor invariance of each background variable was satisfied. According to the analysis of the difference between groups, women had more stress than men in terms of athletic stress and coach stress. The 1st year students had more conflict with teammates than the 2nd year students, and the 3rd year students had high athletic stress, coach stress and life stress.

大倧敎의 神觀에 관한 철학적 연구

이근철(Lee Geun-cheol) 한국도교문화학회 2012 道敎文化硏究 Vol.37 No.-

대종교는 고대부터 내려온 우리 고유의 仙敎, 또는 神敎의 전통을 이어받은 종교로서 고유성을 갖고 있다. 그러면서 대종교의 교리에는 동시대의 다른 민족종교와는 달리 외래종교나 타 종교의 직접적인 영향을 받은 부분이 보이지 않아 독창성도 갖고 있다. 대종교의 초기 경전은 『三一神誥』와 『神事記』, 『神理大典』과 『會三經』등이라 할 수 있다. 『三一神誥』에 담겨 있는 一神은, 세 가지의 성격을 가지고 있으면서 세 가지의 작용을 하시는 분이다. ?神事記?에 나타나 있는 三神은 조화주 한임과 교화주 한웅과 치화주 한검이다. 이에 대해 ?神理大典?에서는 “한얼님은 한임과 한웅과 한검이니라.”고 하면서 “나누면 셋이요, 합하면 하나니, 셋과 하나로써 한얼님 자리가 정해지느니라.”라고 하고, ?會三經?에서는 “하나이자 셋이니 주체로는 더없는 위에 사무치며, 쓰임으로는 더없는 끝에까지 다하시니라.”라고 하여 一神과 三神을 체용의 관계로 연결시켜 三神一體를 말하고 있다. 대종교의 一神에 대한 관념 속에는 고대부터 내려온 우리 고유의 하느님 신관이 담겨 있고, 三神에 대한 관념 역시 환인[한임]ㆍ환웅[한웅]ㆍ단군[한검]을 중심으로 한 우리 고유의 삼신 관념이 담겨 있다. 그러므로 一神의 성격 속에는 기독교적 유일신과는 달리 초월성과 내재성이 융합되어 있고, 三神의 성격 속에는 환웅이 중심인 「단군신화」와 달리 한임과 한웅과 한검의 역할이 조화와 교화와 치화로서 조화를 이루고 있다. 그러면서도 一神卽三神ㆍ三神卽一神의 상호작용 관계로 연결시킨 대종교의 삼신일체적 신관은 기독교의 삼위일체설과는 달리 執一含三과 會三歸一을 중심으로 한體用論的 神觀이라 할 수 있다. 그러므로 대종교의 신관은 우리 고유의 신관을 이어받아 고유성을 지니고 있으면서도, 초월성과 내재성이 융합된 일신론과 조화ㆍ교화ㆍ치화라는 역할 중심의 삼신론이 체와 용으로 연결된 삼신일체라는 관념을 이루어 나름대로의 독창성도 함께 지니고 있다고 할 수 있다. As a religion inherited traditions of our own Seon-Gyo or Sin-Gyo, Daejong-Gyo[大倧敎] has its own uniqueness. Compared to other ethnic religions of the same age, Daejong-Gyo[大倧敎]’s religious dogma has its own originality because it was not influenced by foreign religion or other religion. The earliest scriptures of Daejong-Gyo[大倧敎] are “Sam Il Shin Go[三一神誥]”, “Shin Sa Gi[神事記]” and “Shin Lee Dae Jeon[神理大典]”, “Hwe Sam Kyeong[會三經]”, etc. “Sam Il Shin Go[三一神誥]” discusses single God, “Shin Sa Gi[神事記]” talks about trinity God, “Shin Lee Dae Jeon[神理大典]”considers trinity God as single God, single God as trinity God. “Hwe Sam Kyeong[會三經]” developed and extended this to a view of human, of asceticism and of ethnical belief. The monotheism of Daejong-Gyo[大倧敎] inherited its own religious concept of god from ancient Korea. Also tritheism embodies our own religious concept of god centered around “Hwan In [Han Im]”, “Hwan Wung [Han Wung]”, “Dan Gun [Han Geom]”. This is the reason why monotheism fused with transcendence and immanence is different from protestant monotheistic religion. Regarding characteristics of tritheism, the role of Han Im, Han Wung and Han Geom harmonize with each other as a creation, edification and the government. Religious concept of Trinitarian of DaeJong-Gyo[大倧敎] which connected interaction relationship between monotheism and tritheism, unlike trinitarianism [三位一體] of christianity, is the thing and its function’s theory[體用論] containing the principle as “include three in catching one and return to one in gathering three”. Therefore, the religious concept of DaeJong-Gyo[大倧敎]’s God, which was inherited our distinctive concept of religion has its own uniqueness, and monotheism that is fused into transcendence & immanence and tritheism plays a key role for creation, edification, the government makes concept named Trinitarian[三神一體] which is connects the thing and the function. It could have creativity in its own way.

대종교 경전으로 본 『환단고기(桓檀古記)』 진위 문제

「Hwandangogi」 includes whole scripture of Daejonggyo such as 「Cheonbugyeong」 and 「Samilsingo」, and also along the line of core creed of scripture of Daejonggyo in 「Sinsagi」. However, 「Samilsingo」 in 「Hwandangogi」 has same letters changed in the edition of postscript of 「Samilsingo」, and most of the creed of Daejonggyo in 「Hwandangogi」 are based on the edition of postscript of 「Sinsagi」. And 「Cheonbugyeong」 in 「Hwandangogi」 has also different letters from beginning of script of 「Cheonbugyeong」 that was delivered to Dangungyo. 「Hwandangogi」 is believed to publish using many scripture of Daejonggyo as well as writings of Shin, Chae-ho, fork historian, and several history books such as 「Gyuwonsahwa」, 「Dangigosa」 and so on, with reference. Therefore, it is related to the fact that Lee, Yu-lib who propagated 「Hwandangogi」 learned creed of Dangungyo separated from Daejonggyo in ‘Myeonggyo Hakwon’ of Nokdong Seowon in 1930`s and guided Daejeonsigyodang of Daejonggyo in 1960`s. Lee, Yu-lib asserted that 「Hwandangogi」 was first published in 1911 and transcribed it in 1949. but there is not an original copy to verify, the one published in 1979 is the oldest.

수요감소 요인 외생변수를 갖는 SARIMAX 모형을 이용한 관광수요 예측

In this study, we consider the problem of forecasting the number of inbound foreigners visiting Korea. Forecasting tourism demand is an essential decision to plan related facilities and staffs, thus many studies have been carried out, mainly focusing on the number of inbound or outbound tourists. In order to forecast tourism demand, we use a seasonal ARIMA (SARIMA) model, as well as a SARIMAX model which additionally comprises an exogenous variable affecting the dependent variable, i.e., tourism demand. For constructing the forecasting model, we use a search procedure that can be used to determine the values of the orders of the SARIMA and SARIMAX. For the exogenous variable, we introduce factors that could cause the tourism demand reduction, such as the 9/11 attack, the SARS and MERS epidemic, and the deployment of THAAD. In this study, we propose a procedure, called Measuring Impact on Demand (MID), where the impact of each factor on tourism demand is measured and the value of the exogenous variable corresponding to the factor is determined based on the measurement. To show the performance of the proposed forecasting method, an empirical analysis was conducted where the monthly number of foreign visitors in 2019 were forecasted. It was shown that the proposed method can find more accurate forecasts than other benchmarks in terms of the mean absolute percentage error (MAPE).

水昇火降에 관한 內丹的 硏究

이근철(Lee Geun-Cheol) 한국도교문화학회 2008 道敎文化硏究 Vol.29 No.-

불의 기운은 위로 타오르고 물의 기운은 아래로 흐르는 것이 자연의 순리이다. 그런데 內丹 修鍊에서 말하는 ‘水昇火降’이란 물의 기운은 올라가고 불의 기운은 내려간다는 뜻으로서 자연의 순리와 반대이다. 道家에서는 자연의 순리에 따르는 無爲自然을 말하고 있는데, 도가에 바탕을 둔 내단수련은 자연의 순리를 거스르는 것인가? 心火와 腎水가 승강하는 任ㆍ督脈의 경로에 있어서 醫家와 內丹家 모두 본래의 흐름은 아래에서 위로 올라간다고 하였다. 단지, 내단가에서는 수련을 통해 기의 흐름을 조절하여 任脈은 위에서 아래로, 督脈은 아래에서 위로 흐르게 한다고 말하고 있다. 결국 내단 수련에서는 임ㆍ독맥에서 기가 흐르는 방향을 자연적인 경로에 맡겨두지 않고 有爲하게 조절하여 인체에 변화를 주고자 한 것이다. 원래 인체는 조화의 원리에 의해 생성ㆍ변화해 왔다. 그러나 사회가 분화되고 복잡해지면서 조화의 원리가 무너지고 인체 역시 균형이 깨어지게된 것이다. 그러므로 내단 수련을 통해 수승화강을 이루면 인체가 갖고 있던 원래의 균형을 되찾게 되는 것이다. 그러므로 내단 수련은 有爲에서 시작하나 無爲로 나아간다고 할 수 있다. 일상적으로 심신이 안정된 상태에서도 수승화강은 가능하다. 그러나 내단을 형성하기 위해서는 心火 가운데 眞水가 발생하고, 腎水 가운데 眞火가 발생하여 水火의 交가 이루어질 때 진정한 의미의 수승화강이 이루어진다. 수승화강은 인체의 본래 모습을 되찾기 위해 필요한 내단 수련의 핵심이다. 내단 수련을 통해 수승화강을 이루면 생명 에너지를 극대화 할 수 있고 인체가 가지고 있는 본래의 순수한 모습으로 돌아갈 수 있다. 그러므로 수승화강은 자연의 원리를 거스르는 것이 아니라 자연적인 생명 원리의 근원에 소급하는 것이라 할 수 있다. The laws of nature are that the energy of fire burns up and the energy of water flows down. However, as suseunghwagang (水昇火降) of neidan discipline is that the energy of water goes up and the energy of fire goes down, it is opposite to the laws of nature. Although Doga (道家) teaches muwijayeon(無爲自然) that follows the laws of nature, does neidan disciple based on Doga go against the laws of nature? In the course of imㆍdokmaek (任督脈), in which simhwa (心火) and sinsu (腎水) go up and come down, both of Uiga (醫家) and Naedanga (內丹家) say that the original flow goes from down to up. Merely, Naedanga insists that immaek (任脈) goes from up to down and dokmaek (督脈) goes from down to up by controlling the flow of energy through discipline. After all, neidan disciple controls yuwi (有爲) to give changes to the human body by not allowing the flow of energy to follow the course of nature in imㆍdokmaek (任督脈). The human body has been formed and changed by the laws of harmony. However, as the society has been divided and complicated, the law of harmony has been collapsed, and also the balance of the human body has been broken down. If you achieve suseunghwagang through neidan discipline, you can recover the balance that your body originally had. Therefore, it is said that neidan discipline starts from yuwi but reaches muwi (無爲). Suseunghwagang is possible even when your mind and body is stable in your daily life. However, real suseunghwagang can be accomplished in the state of a gyogu (交?) of fire and water, which is realized as jinsu (眞水) is made in simhwa (心火) and jinhwa (眞火) is made in sinsu (腎水) in order to form neidan. Suseunghwagang, which is needed to recover the original human body, is a core of neidan discipline. When suseunghwagang is achieved through neidan discipline, the energy of your life can be optimized and you can return to the pure human body that your body originally had. Therefore, suseunghwagang does not act against the laws of nature but goes back to the origin of the laws of natural life principle.
