The purpose of this study was to develop a wearable platform system that can detect and acquire a soldier’s biosignals (i.e., heart activity signal, respiration rate, etc.) in a nonrestrained, unconscious manner. These detected biosignals are transmitted to a processing device to analyze and monitor the soldier’s physical status. To achieve this, textile-based heart activity electrodes and a strain gauge sensor for the respiration signal measurement were developed, and their performances in detecting each signal were verifed. These sensors were embedded in a chest belt to design a wearable platform that can simultaneously measure heart activity and respiration signals. The sensor part of the chest belt has a dual layer structure to detect high-quality signals. Stretch fabric was used on the outer layer and a respiration sensor was attached to the belt. On the inside layer, a non-stretch fabric was used as the base fabric and a heart activity-sensing electrode, that is capable of taking measurements using a modifed lead-II heart activity signal induction method, was embroidered onto the fabric. Subjects were asked to wear the chest belt, and a biosignal processor module was attached to verify the system’s performance while simultaneously acquiring the heart activity and respiration signals. More specifcally, it was confrmed that the two signals were detected in a stable. It is expected that the biosignal-monitoring wearable platform system developed in this study will be able to efectively analyze and monitor soldiers’ biosignals.

영업사원들의 일-가정 갈등과 사회적 지원에 대한 탐색적 연구

조광주(Jo, Kwang-Joo),조문기(Cho, Mun-Kee) 글로벌경영학회 2012 글로벌경영학회지 Vol.9 No.4

최근 산업사회로부터 지식사회로의 변화가 빠르게 진행되면서 일과 가정사이의 갈등이 증폭되고 있다. 이 두 영역의 갈등은 당사자인 영업사원의 삶의 질과 건강만 해칠 뿐 아니라 가족구성원, 직장동료, 나아가 조직의 성과에 이르기 까지 다양한 수준에 걸쳐 심각한 부정적 영향을 미칠 수 있다. 이에 일과 가정사이의 갈등관계를 분석하여 이를 조절할 수 있는 방안에 대한 연구가 시급한 실정이다. 본 연구는 일과 가정사이 갈등으로 힘들어하는 영업사원을 조사하여 일과 가정사이의 상호 역할관계를 실증분석하고자 하였다. 이 과정에서 일과 가정사이 갈등을 WIF(work interference with family:일 초래 갈등), FIW(family interference with work:가정초래 갈등)으로 분류하였고, 이 갈등 요인들이 가족 또는 회사 상사, 동료의 사회적 지원과 기업의 제도적 지원으로 얼마나 조절되는지 알아보았다. 이를 실증분석하기 위해 보험회사에 근무하는 직장인 10명과 자동차에 근무하는 직장인 7명을 심층면접 설문 조사 하였다. 연구의 결과, 영업사원들이 일과 가정사이 개체들의 깊은 부정적 갈등관계를 확인하였고, 이를 해결하기 위한 직장, 가정 내 조절 장치들 중 효과적으로 이 갈등을 줄이는 지원요소들의 긍정적 작용과 부정적 작용을 확인할 수 있었다. 가정의 사회적 지원은 업무에 큰 영향을 가져왔으나 상사와 동료의 사회적 지원은 시기, 질투를 야기하였고, 기업의 제도적 지원은 조직기강의 해이를 가져오기도 하였다. 본 연구는 일과 가정사이 갈등을 더욱 실증적으로 분석할 수 있는 정량연구에 대한 필요성을 확인하였다. In this study, the concepts of work interference with family (WIF) and family interference with work (FIW) were reified through the investigation of sales persons who has relatively more conflicts between work and family. In addition, these conflicts were studied how to adjust the factors of conflict by family’s social supports and Supervisory and Coworkers’ social support, and how family friendly support system from their companies to adjust the conflicts between work- family. Through the analysis of interview question survey of 10 insurance sales and 7 car sales, we have found the results as follows. First of all, WIF of sales person was divided into three types, such as role overload, job conflict and job ambiguity. In second, FIW of sales person was classified as husband and wife conflict, and economic conflict. Considering these kinds of family induced conflict, sales person could face family interference with work (WIF). In third, moderating role from social support to FIW which gives negative effect to sales performance was investigated. From this study, social support and company’s support system should be institutionalized, and the results implied an empirical research in order to examine the relationship among the research constructs.

In this study 8 male athletes and 8 female athletes for matches requiring endurance were examined for the purpose of comparison and analysis on the effect of absorption of sugars and effect of absorption of sugars+protein+fats restoration of muscular glycogen after elapse of 4 hours subsequent to closing 90 minutes exercise. (Amount of energy absorbed was same). Examinees were tested with 3 kinds of performance such as CPF Performance whereby they were made to take ① sugars (0.75 g/㎏) and protein (0.1g/㎏) and fats (0.02 g/㎏) after elapse of 1 hour subsequent to long hours of exercise and CHO Performance whereby examines were made to take ② sugars (1g/㎏) alone and Performance whereby they were made to take ③ placebo (which does not contain any sugars, protein or fats). Also the examinees took meals which had same amount of energy and nitrogen during the Performance on the date prior to experiment or on the date of experiment. Women during the exercise showed significantly higher rate of oxidation of fats, basic element of energy than that of men. In CHO Performance and CPF Performance value of blood sugar and density of insulin were significantly higher in comparison with performance with placebo. At such cases there was no difference between different genders. Same kind of phenomena were confirmed with restoration of muscular glycogen. From such fact it could be observed that absorption of fats alone and absorption of sugars+protein+fats in comparison with absorption of placebo after exercise promoted relatively higher level of restoration of muscular glycogen for both men and women.

‘나’의 기원으로서의 ‘단군’과 창세기적 문학사상의 의미 : 최남선, 신채호를 중심으로

조은주(Cho Eun-joo) 한국현대문학회 2009 한국현대문학연구 Vol.0 No.29

이 논문은 1920년대 개벽사상과 단군복원운동이 내재하고 있었던 ‘창세기(創世記)적 사유’에 주목하고 그 사유의 방향성을 포착하려는 시도이다. 창세기는 흡사 카오스적 ‘혼돈’으로 파악되고 있었던 당대 불행한 시대를 구원하기 위해 호명되고 있다. 민족의 시원을 표상하는 단군의 복원이란 창세기적 장면의 재현으로 이해될 수 있다. 최남선과 신채호는 실증적인 자료를 섭렵하며 단군의 실체를 검증하려 했고, 단군을 통해 조선의 고유한 정신을 찾으려 했던 대표적 작가이다. 이는 문학적 텍스트에서뿐만 아니라 역사학자의 입장에서도 그들에게 중요한 문제였다. 최남선이 주창한 불함문화권의 중심과 신채호가 내세운 역사철학인 ‘회통’의 중심에, 모두 ‘단군’이 놓여져 있기 때문이다. 최남선과 신채호의 특별함은 단군에 대한 사유를 ‘我’와 ‘自己’의 기원에 관한 사유와 중첩 시키며, ‘나’의 계보에 대한 탐색을 자신들의 역사학의 방법론 혹은 핵심적 사상으로 환치시켰다는 점에 있다. 자아를 포괄하여 세계와 온 우주 전체를 재창조하려는 개벽시장 위에, ‘나’의 개념과 그 기원을 탐색하는 계보학적 사유를 결합시키는 방식, 이것이 이 글에서 살펴본 두 작가의 창세기적 사유이다. 창세기적 사유는 직접적으로 단군을 호명하는 역사학적 텍스트뿐만 아니라 은유적 차원에서도 동원되었던, 새로운 세계를 건설하려는 낭만주의적 기획과도 같았다. Ghoi Nam-sun and Shin Chae-ho reviewed Dan-gun's texts from the 1920s and 1930s in order to study the traditional spirit of Cho-sun. Dan-gun is at the cultural center of Bulham(不咸) that Ghoi Nam-sun advocated, but Dan-gun is also at the center of Hoetong(會通) that Shin Chae-ho advocated. Gae-byeok(開闢) was connected with the Cheondo religion, therefore we assume that the texts related to Dan-gun are connected to Gae-byeok's magazine idea. Specifically, Ghoi Nam-sun and Shin Chae-ho summarized Dan-gun's thoughts on the origin of Na, and they replaced a search of Na's genealogy with their historical analysis. They combined Gae-byeok's ideas, recreated the world and the universe including ego and considered the origin of Na. In this essay, Genesis as a literary idea is examined, as Genesis is also a romantic plan to establish a new world.

Clinical Significance of Classification of Graves` Disease According to the Characteristics of TSH receptor Antibodies

(Won Bae Kim),(Hyun Kyung Chung),(Young Joo Park),(Do Joon Park),(Hong Kyu Lee),(Bo Youn Cho) 대한내과학회 2001 The Korean Journal of Internal Medicine Vol.16 No.3

N/A Background:It has been widely accepted that the epitope (s) and/or functional characteristics of thyrotropin receptor antibodies (TSHRAb) from Graves` patients are heterogenous among patients. However, the clinical significance of such heterogeneity has not been systematically evaluatedyet. We were to elucidate and find the clinical significance of heterogeneity for TSH receptor antibodies in Graves` disease. Methods:We measured stimulating TSHRAb (TSAb) activities using CHO-hTSHR cells, FRTL-5 cells and chimeric receptor expressing cells (Mc1+2 and Mc2), specific blocking TSHRAb (TSBAb) activities using Mc2 cells and TBII activities using porcine thyroid membrane in 136 patients with untreated hyperthyroid Graves` disease. Results: Based on various TSHRAb activities from each patient, the patients could be categorized into 7 subgroups by cluster analysis; 1) Group 1 (n=41) was characterized by moderate TSAb activities bothin CHO-hTSHR cells and in FRTL-5 cells, typical TSAb epitope, rare blocking antibodies and high TBII activities. 2) Group 2 (n=16) was characterized by the presence of blocking TSHRAb in most patients, albeit the other characteristics were the same as those in Group 1. 3) Group 3 (n=19) patients had low TSAb activities bothin CHO-hTSHR cells and in FRTL-5 cells, seldom had blocking TSHRAb, but they had high TBII activities. 4) Group 4 (n=30) could be categorized as `mild disease` group, as they had low activities in all kinds of TSHRAb assay and had low antim icrosomal antibody activities. 5) Group 5 (n=14) was characterized by moderate TSAb activities with atypical epitope (s), rare blocking TSHRAb and moderate TBII activities. 6) Group 6 (n=10) patients had veryhigh TSAb activities with typical epitopes, seldom blocking TSHRAb and low TBII activities. 7) Group 7 (n=6) was characterized by very high TSAb activities with atypical epitopes and high TBII activities. Pretreatment serum thyroid hormone level was low only in group 4 patients compared to the other 6 groups (p<0.05). The size of goiter was significantly larger in those in group 1 and group 3 (p<0.05) compared to the other 5 groups. The prevalence of clinically significant ophthalmopathy was higher in group 2 patients than the other 6 groups (50%vs.27.5%,p=0.06). Among 6 kinds of TSHRAb activities, only the blocking TSHRAb activity was significantly associated with the presence of ophthalmopathy in multivariate analysis. Conclusion:These results suggest that the differences inepitopes for TSAb or the presence of blocking TSHRAb is not a major factor in determining the degree of thyrotoxicosis in Graves` disease. Although the pathogenic mechanism is not clearyet, we suggest that patients with ophthalmopathy have different TSHRAb repertoire from those without ophthalmopathy in Graves` disease.

組織 硏究에서의 狀況理論(Contingency Theory)의 有用性과 限界

趙柱瑩 東亞大學校 大學院 1991 大學院論文集 Vol.16 No.-

Basically, the contingency approach theorizes that different situations and conditions required different management approach. The contingency theory is characterized as follows : (1) build up of macro organization theory between organization and environment, (2) holistic theory of organization with open system, (3) attachment of importance on design and strategy of organization theory, (4) orientation to the integration theory on axis of relation of organization and environment. And it is an accumulated proposition, which is able to positive study of organization, which is to make an itegrated theory. The theory shows a new way of managemnt and organization theory. To analysis effectively the impacts of the technology on the orgznizational structure, it is severely required to establish more sophisticated model which incorporates various demensions of the technology and the organizational structure. To analysis more effectvely the impacts of the organizational size on the structure of organization, it is required to consider both formal and informal aspects of organizational structure concurrently. The contingency theory of organization in wider sense deals with the relationship between environment and organization. The envrionment-structure relationship is complicated, but we concluded that (1) the envrionment's effect on an organization is a function of dependence, (2) a dynamic envrionment has more influence on structure than does a static one, (3) complexity and envrionmental uncertainty are directly related, (4) formalization and envrionmental uncertainty are inversely related, (5) the more complex the envrionment, the greater the decentralization, and (6) extreme hostility in the envrionment leads to temporary centralization. Recent research suggests that there are three key to any organization's envrionment. They are labeled : complexity, routineness, and volatility. Given this three-dimensional definition of envrionment, we can offer some general conclusions. The more complex the envrionment, the more participational a structure should be. High envrionmental routineness can be managed more effectively in bureaucratic (mechanistic) structures. High envrionmental volatility can be managed more effectively in Organic Structures (Adhocracy). In spite of this contribution, however, it has some deffects. Adoption of open-defined contingency variables make the theory always true. This cannot fulfill the Popper's criterion of science that a scientific statement must be falsifiable. In fact a researcher could select the envrionmental factors arbitrarily, and be could set up the uncertainty on those factors. Moreover, its true implication is controlling the organization, and the standard of organizational performance is exclusively effectiveness or perofitability, so the contingency theory is criticized as a product of the conservative ideology. The contingency theory of organization must diminish the the weight of contingency variables.

Bernard Bass의 變形리더십 이론에 관한 연구

趙柱瑩 東亞大學校 大學院 1994 大學院論文集 Vol.19 No.-

Leadership research over the last forty years has been on transactional leadership. Transactional leaders clarify for followers their responsibilities, the expectations they have, the tasks that must be accomplished and the rewards followers will receive for fulfilling the contract or agreement with the leader. It is not, however, sufficient to explain the full range of effort and performance that some leaders are able to extract from their followers Followers may produce far beyond what is expected of them because of their commitment to the leader, their trust in the leader's vision, and their desire for change. Consequently, a new model of leadership is required to explain such higher order effects on followers and their organization. Transformational leaders motivate followers to do more than they originally expected. Original performance expectations are enhanced by increasing each follower's level of confidence. The process of transforming followers does not involve merely empowering or delegation to followers the responsibility to take on a goal ; rather, followers develop their capability to determine the appropriate course of action. Transformational leaders are characterized by Burns(1978) as raising the consciousness levels of followers about the importance and value of designated objectives and pointing out ways of achieving them. They also help followers to transcend their own selfpinterests for the sake of the mission and vision of the organization. Transformational leaders are likely to become charismatic in the eyes of their followers and to be seen as holding much referent power and influence. Followers want to identify with them and their mission and view such leaders can occur without charismatic identification. Inspirational leaders can articulate in simple ways shared goals and a mutual understanding of what is appropriate and important to consider. They provide visions of what is possible and how to attain specific goals. Individualized consideration is a distiguishing characteristic of transformational leadership. It means understanding and sharing in the follower's concerns and developmental needs, while treating each follower uniquely. It also represents an attempt on the leader's part to both recognize, understand and satisfy current needs of his or her followers, while also elevate those needs to develop followers to higher levels of potential. In addition to charisma, inspiration and individualized consideration, transformational leadership also involves the intellectual stimulation of follower' ideas, attitudes and values. Through intellectual stimulation, transformational leaders help followers think about old problems in new ways. The process by which charismatic leaders arouse enthusiasm and commitment in followers is still not cler, but an important comonent is the leader's articulation of an appealing vision that taps the conscious or unconsciouss needs, values, and feelings of followers. Transformational leadership increases follower motivation by activating oranizational policies, structures, and culture, thus greatly improving the overall performance of both individual members and the organization as a whole. Increased transformational leadership and its effects can occur at every organizational level.

趙必嬌,蘇珠嬉 慶北大學校 師範大學 1980 敎育硏究誌 Vol.22 No.-

Triboelectric properties of woolen fabrics on the clothing have been investigated in atmosperic ambient of 20℃ 75% RH. Woolen fabrics which are charged up by friction each, for other-example, over wear and under wear, give fabrics absorption, electric shock and other problems of health in winter especially. So authors have studied on triboelectric properties of the woolen fabrics by friction of the fabrics, nylon, acetate, polyester, exlan, viscose and cotton, and have measured surface resistivity of the samples. The results were as follows. Charge quantity on woolen fabrics of Plain weave, Twill weave and Satin weave were less than that of knitting fabrics. Cotton and viscose were suitable to under-wear or lining of woolen fabrics, and nylon was more suitable than acetate, polyester, exlan in this experiment. Surface resistivity-and charge quantity of warp direction were less than those of weft and bias directions on nylon, and the surface resistivity and charge quantity of course direction were less than those of wale, bias direction on woolen jersey.
