Recently, in the field of industrial servo-systems, several methods have been proposed for tracking the reference input fastly and finely without overshoot. These methods, however, are established under hypothesis that structure and parameters of the plant are known accurately and they are time invariant. In practice, it is difficult to obtain the values of plant's parameters accurately and usually plants change with time and operation conditions. In this paper a method to construct the nominal model tracking adaptive control system is proposed. The system is composed of the nomial model which produces a ideal response and the model tracking system with the fuzzy adaptive controller. If the actual plant is equal to the controlled object in the nominal model, the output of the plant is the same as that of the nominal model and the fuzzy adaptive controller becomes idle. However, when the plant changes, the fuzzy adaptive controller of the tracking system operates in order for the output of the plant to track the ideal response. Through the computer simulations under various conditions, it is confirmed that the proposed model tracking system is very effective.

이 연구의 목적은 민간경비원의 조직문화와 직무스트레스 및 조직몰입의 관계를 규명하는데 있다. 이 연구는 2011년 수도권소재(인천) 공항에서 재직하고 있는 민간경비원들을 모집단으로 설정한 후 유의표집법을 이용하여 최종분석에 이용된 사례 수는 총 203명이다. 연구에 사용된 설문지는 총 56문항으로 구성되었다. 분석방법은 SPSSWIN 18.0을 이용하여 빈도분석, 요인분석, 신뢰도분석, 회귀분석 등을 실시하였다. 설문지의 신뢰도는 Cronbach's ${\alpha}$값이 .671이상으로 나타났다. 결론은 다음과 같다. 첫째, 민간경비원의 조직문화는 직무스트레스에 영향을 미친다. 즉, 개발적, 위계적 문화가 형성 되지 않는다면, 보상경력개발에 대한 직무스트레스는 증가한다. 반면, 개발적, 합의적 문화가 형성 되면, 직무특성, 인간관계, 역할과 관련된 직무스트레스는 감소한다. 둘째, 민간경비원의 조직문화는 조직몰입에 영향을 미친다. 즉, 개발적, 위계적 문화가 형성 되면, 정서적, 근속적, 규범적 몰입은 높아진다. 셋째, 민간경비원의 직무스트레스는 조직몰입에 영향을 미친다. 즉, 보상경력개발이 불공정하게 이루어질수록 정서적, 근속적 규범적 몰입은 낮아진다. 반면, 현재 자신의 직무가 능동적으로 이루어진다면, 정서적, 근속적, 규범적 몰입은 높아진다.

The purpose of this study was to examine the factors influencing copyright protection decision-making among Korean eSports game users. Data collection was conducted over a month at an eSports arena located in Seoul. Of the surveys collected, 354 valid data (88.5% of response rate) were analyzed in SPSS Ver. 20.0 through descriptive statistics, correlation and multiple regression analysis. The results showed that copyright protection decision-making regarding eSports contents was significantly influenced by legal/moral norm, perceive group norm, and past habit/behavior. Among the factors, legal/moral norm was found to be the most influential on copyright protection decision-making.

This study examined the fashion culture of 20-30s working women through clothing norm relationships in the workplace. A literature research was conducted along with qualitative research, in-depth interviews in order to understand the domestic working environment and fashion culture such as lifestyle and consumer culture characteristics of 20-30s working women. The results were: First, it showed that the increased number of members having various inclinations caused subcultures through an increase of women's economic activities and transition to a knowledge-information society in domestic work places that changed into a business casual that recognized employees' autonomy and diversity. Second, in the working place, clothing norms coexist as stipulated by statutes, company rules, and official documents as well as others implied by experiences of sanction against members. Workplace closing norms are classified into norms of exposure that draw attention to clothes and casual clothes. Third, it showed that factors pressuring clothing norms are classified as external pressures and by spontaneous self-censorship that cause conflict and confusion with working women's fashion according to the degree of pressure. Two kinds of pressure by others (or types of departments and members) were observed.

본 연구에서는 종합병원에 근무하는 간호사를 대상으로 감정노동과 감성지능이 직무스트레스에 어떠한 영향을 미치는지 알아보고자 한다. 본 연구에서 간호사들의 감정노동과 감성지능 변인들의 직무스트레스에 대한 분산 설명력은 31.9%였고, 회귀모형은 유의미한 것으로 나타났다(F=7.615, p<.001). 분석결과, 감정노동 변인 중 감정표현의 빈도는 직무스트레스에 유의미한 부(-)적 영향(${\beta}=.206$ p<.05)을, 감정표현 규범의 주의성은 유의미한 정(+)적 영향(${\beta}=.318$, p<.01)을 미치는 것으로 나타났으며, 감성지능변인 중 자기감정이해(${\beta}=.195$, p<.05)와 감정조절(${\beta}$=-.192, p<.05) 변인이 직무스트레스에 유의미한 부(-)적 영향을 미치는 것으로 나타났다. 이들 변인들의 상대적 영향력은 표준화계수(${\beta}$)를 통해 알 수 있듯이, 감정표현 규범의 주의성, 감정표현의 빈도, 자기감정이해, 감성조절 등의 변인 순으로 직무스트레스에 미치는 영향력이 큰 것으로 분석되었다. 이와 같은 결과를 통해, 간호사들이 직무스트레스를 낮추기 위해서는 환자들과 긍정적인 감정표현을 많이 하고, 간호사들이 병원의 감정표현 규범으로 인해 표현하지 못한 감정을 해소할 수 있는 방안이 필요하며, 자신의 감정에 대한 이해와 감성조절 능력을 기르도록 스스로 노력이 필요함을 알 수 있었다.

This paper is concerned with identifying the determinants of committing digital piracy in university settings. Using a theoretical model based on Theory of Reasoned Action, the causal relationship among the research variables, including intention to commit digital piracy, attitude, subjective norm and fear of legal consequences, is developed. Results from 295 survey responses indicate that fear of legal consequences affect the subjective norm and the attitude, which in turn influence the intention to commit digital piracy. In addition, relativism based on EPQ(Ethics Perception Questionnaire) is introduced as a moderating variable. The relative influences of path coefficients are investigated and implications from findings are also discussed.

This article investigates the impacts of firms' regulatory compliance and voluntary innovation activities in environmental management on the development of their organizational capabilities and the enhancement of their performance, within the Korean context. The study invokes a structural equation analysis. The results indicate that voluntary innovation activity in response to market pressures makes a significant contribution to the development of firm-specific organizational capability and the enhancement of firms' performance, but regulatory compliance activity does not significantly affect either organizational capability or performance. This capability was also seen to have implications for firm's performance. This article also suggests several policy implications related to the research.

The right to the spectrum frequency and orbit is required for the broadcasting by satellite, whether the broadcaster might be given any license or authorization for the broadcasting. The reason is that the ITU Convention and Radio Regulation provide very specific and detailed rules regarding the utilization of the frequency spectrum and orbit. Outstanding issue arises as to the implementation process of the rules of international character. Domestic implementation of the Radio Regulation, in the way of letter to letter should be discouraged when the competitiveness of domestic industry vis-a-vis foreign competitor is taken into account.

This study focuses on social norms and perceived benefits that are expected to lead to purchase fashion goods selling by social enterprises that can help guide the establishment of effective sales strategies for social enterprises. The relationships among two social norms (injunctive norms and descriptive norms), three perceived benefits (cause benefits, psychological benefits, and social image benefits), and purchase intention were investigated respectively. Data were collected via an online web survey and 11 hypotheses were statistically tested by using PLS-SEM analysis. Purchase intention toward the fashion products of social enterprises was influenced by four antecedent variables (injunctive and descriptive norms, cause and psychological benefits) excluding only social image benefits. However, descriptive norms only affected psychological benefits while injunctive norms only affected social image benefits. The findings suggest that the owners or marketers of social enterprises need to create a social atmosphere in which more consumers buy the fashion goods for social enterprises and emphasize consumers' psychological benefits that they feel mentally more comfortable by purchasing the fashion goods of social enterprises.

This paper investigates the differences in norms, values, and trusts that affect the quality of life of the elderly, as well as the elderly population. The elderly surveyed 401 households (65 years old or older) residing in N city. As a result of the analysis, there was a difference in life satisfaction according to sex, marital status, educational background, type of household composition and income level in the comparison of life satisfaction according to demographic variables. As a result of examining the influence of social capital on the elderly's life satisfaction, it was found that they contributed to trust, norm, and participation order. This study suggests that future policies of the elderly welfare policy should be considered as a policy that focuses on participation in various social activities that can activate social capital.
