우리 사회에서 일정 정도 이상의 사회와 가정에서의 기능상의 부적응을 초래하는 정신적 문제는 경제활동인구에 있어 가장 흔한 보건의료상의 문제일 것으로 추측되고 있으나, 현재까지는 정신보건제도 마련에 있어 가장 극심한 부적응을 보이는 정신적 장애를 지닌 환자를 위주로 수용시설과 지역사회에서의 재활과 관리에 그 초점을 두어 왔다. 즉 직업스트레스와 같은 일시적인 사회심리적 갈등으로 인한 신체증상의 호소나 알을 및 약물중독으로 인한 사고의 발생으로부터 일생동안 관리되어야 하는 지능저하나 학습장애와 같은 만성적인 문제에 이르기까지 다양한 스펙트럼을 보이는 사업장과 지역사회에서의 정신적 문제들 중 그 일부만이 제도적으로 관리되어 왔다. 실제 그 동안 직장 내 정신보건문제에 대한 행정적 관심은 일부 장애인의 취업 문제를 제외하고는 없었다고 하여야 할 것이다. 그러나 한편으로 우리 사회의 산업구조와 경제사회적 조건의 변화에 따른 노동내용과 조건상 유연화의 증대가 많은 직장에서 노동강화로 이어진다는 점, 그리고 가족 및 교류집단을 비롯한 전통적인 사회적 지지구조가 와해되고 있다는 점과 정신적 문제로 인한 기능상 부적응의 척도가 한편으로 사회적 가치관의 변화에 따라 계속 그 영역이 넓어지는 방향으로 변화하고 있다는 점등에서 직장 내 정신보건 문제는 앞으로 더욱 그 비중이 커질 것으로 판단되고 있다. 문제의 심각성에 대한 관심이 요구되는 현재의 시점에서 제도적 접근에 대한 검토 또한 시작되어야 할 것으로 판단되고 있다. 현재까지 기업 내에서 이루어지고 있는 정신보건관리의 현황을 단편적으로 파악해 보았을 때, 단지 일부 기업에서 취업시 내지는 부서 배치시 성격검사를 비롯하여 적성검사를 실시하고 있으며, 기업윤리확보 차원에서 비정규적으로 사기앙양을 주목적으로 하는 집단적인 교육이나 단체훈련이 이루어지고 있으나, 정신심리적 문제를 개인적 차원에서 그리고 또한 조직적 차원에서 체계화된 프로그램으로 관리하고 있는 사례는 아직 없다. 앞으로 직장 내 정신보건문제에 대하여 제도적인 접근을 하기 위하여서는 다음과 같은 세가지 조건들이 구비되어야 할 것으로 판단된다. 첫 번째로 문제점 그 자체의 내용과 그 규모에 대한 정확한 파악과 예측이 가능하여야 한다. 즉 제도 전체의 운영을 객관적으로 평가하고 개선할 수 있는 기제가 함께 있어야 제도가 실제적인 기능을 할 수 있다는 최소한의 목적이 달성될 수 있다. 두 번째로 문제점의 관리를 위한 효과적인 개입내용 및 개입지점의 확보가 가능하여야 한다. 특히 직장 내에서 수행할 수 있는 프로그램이 개발되어야 하며, 이는 시범사업과 시장을 통한 소비자, 즉 사업주들의 자발적인 선택을 통하여 검토되고 걸려져야만 한다. 마지막으로 제도 운영의 대상, 특히 정신보건문제를 안고 있는 노동자들의 자발적인 동의가 확보될 수 있어야 한다. 이는 정신적 문제가 안고 있는 편견과 그로 인한 차별이 가져다주는 문제를 함께 고려하면서 제도가 운영되어야 하며, 이에 있어 제도 운영상 노동자들의 주체적인 참여가 필요하기 때문이다. 이상 고려되는 직장 내 정신보건문제에 대한 제도적 접근을 담기 위하여서는 프로그램 개발이나 전문가 집단의 양성과 같은 단순한 기술적 접근과 이들의 인허가 및 사업화에 따른 적용기준 및 의무의 설정과 같은 제도적 접근에 그쳐서는 그 실효성을 담보하지 못할 것으로 판단된다. 보다 중요한 것은 이러한 정신보건문제에 대한 노사의 공감대를 이루어 내는 것이며, 사회 전반적인 인식의 확산과 더불어 바람직한 관리모습에 대한 사회적 가치관을 도출해 내는 것이 제도적인 접근의 성공을 보장할 수 있는 기반 조건이 될 것이다. 이러한 점에 있어 정신보건문제를 바라보는 기존의 가치관이 부정적이고 고착화된 모습만을 강조하였으나, 이제는 점차 긍정적이 사회활동에 수반되는 역동적인 모습으로서 비추어지는 것이 많아진다는 측면에서 그 전망을 밝게 하여 주고 있다.

The purpose of this paper is primarily to introduce a nonparametric statistical tool developed by Baek and Brock to detect a unidirectional causal ordering between two economic variables and apply it to interesting macroeconomic relationships among money, production and prices. It can be applied to any other causal structure, for instance, defense spending and economic performance, stock market index and market interest rates etc. A key building block of the test for nonlinear Granger causality used in this paper is the correlation. The main emphasis is put on nonlinear causal structure rather than a linear one because the conventional F-test provides high power against the linear causal relationship. Based on asymptotic normality of our test statistic, the nonlinear causality test is finally derived. Size of the test is reported for some parameters. When it is applied to a money, production and prices model, some evidences of nonlinear causality are found by the corrected size of the test. For instance, nonlinear causal relationships between production and prices are demonstrated in both directions, however, these results were ignored by the conventional F-test. A similar results between money and prices are obtained at high lag variables.

Currently, road mobility improved from the National Road Improvement. Nevertheless delineation system is facility that enhanced driver's safety, that was set up often inconsistent or nonexistent over the road exit ramp So it judged functional investigation will be necessary. This study suggested setting type of the delineation system. That was based on a field study and reviews the legal standard of it and considering driver's cognition behavior. For the study, make a 3D-simulation and so could objectively a comparative test. Comparison variable between delineation setting type is selected conspicuity and visibility. Cased that illustrated characteristics of driver's visual cognition behavior. The experiment was used Eye Marker Recorder for measure the gaze frequency more quantitatively and objectively. And used the ANOVA analysis for significance testing between delineation setting type. A significant percent of the conspicuity analyzed types(Safe mark, Obstacle Sign, Warning Light, and Tubular Maker) in road exit ramp for recognize. And gaze frequency that measure of effectiveness of visibility are measured. On the analysis result, the visibility was significance difference between delineation setting type and visibility of types was best.

Following the recent advancement in the use of social networks, a vast amount of different online reviews is created. These variable online reviews which provide feedback data of contents' are being used as sources of valuable information to both contents' users and providers. With the increasing importance of online reviews, studies on opinion mining which analyzes online reviews to extract opinions or evaluations, attitudes and emotions of the writer have been on the increase. However, previous sentiment analysis techniques of opinion-mining focus only on the classification of reviews into positive or negative classes but does not include detailed information analysis of the user's satisfaction or sentiment grounds. Also, previous designs of the sentiment analysis technique only applied to one content domain that is, either product or movie, and could not be applied to other contents from a different domain. This paper suggests a sentiment analysis technique that can analyze detailed satisfaction of online reviews and extract detailed information of the satisfaction level. The proposed technique can analyze not only one domain of contents but also a variety of contents that are not from the same domain. In addition, we design a system based on Hadoop to process vast amounts of data quickly and efficiently. Through our proposed system, both users and contents' providers will be able to receive feedback information more clearly and in detail. Consequently, potential users who will use the content can make effective decisions and contents' providers can quickly apply the users' responses when developing marketing strategy as opposed to the old methods of using surveys. Moreover, the system is expected to be used practically in various fields that require user comments.

This study aimed to assess the educational need for management of communicable disease prior to developing curriculum for Field Epidemiology Specialist Training Program on Infectious Disease. We sent questionnaires(72 items) to two personnels who were related to communicable disease in each public health center through e-mai and 300 were returned(62.0% of response rate). The subject for education which showed the highest educational need was management(2.31 point), followed by immunization(2.30 point), and the lowest was surveillance(2.10 point). Generally, the educational need was higher in the aspect of attitude or practice than in that of knowledge. The subject which showed the differences in educational need by job titles were immunization(p<0.01), outbreak investigation(p<0.01), and case management and sanitation(p<0.01). There was negative correlation between communicable disease management-working duration and educational need. Considering this result, the curriculum should be focused on strengthening the ability for problem-solving especially in management and immunization.

We report and analyze the Korean physicians' recent general strike over the implementation of the Separation of Prescribing and Dispensing Practice (SPDP) in which more than 18,000 private clinics and 280 hospitals participated. Utilizing game-theoretic models of bargaining we explain why the Korean physicians were so successful in organizing intense collective action against the government and securing very favorable policy outcomes. In particular, we highlight the role of distributional conflict among social actors in shaping the details of institutional reform. The introduction of the SPDP was a necessary first step in the overall reform of health care system in Korea. However, the SPDP was perceived to be a serious threat to the economic viability of their profession by the vast majority of Korean physicians who had long been relied on the profits from selling medicines to compensate for the loss of income due to the low service fee under the previous health care system. The strong political coalition among heterogeneous physicians enabled them to organize an intense form of collective action, the general strike. Thus, physicians were successful not only in dragging the government to a bargaining table, but also winning in the bargaining and securing an outcome vastly favorable to them. On the other hand, the lack of an overall reform plan in the health care policy area, especially the finance of the National Health Insurance and the need for maintaining an image as a successful reform initiator, motivated the government to reach a quick resolution with the striking physicians.

This study attempts to explore and describe the public's image on social welfare professionals in the comparison with other helping professionals. Using a sample (n=1,156) collected from high school students, college students, and citizens, this study comparatively examines the public's image on five helping professionals such as social welfare professionals, psychiatrists, clinical psychologists, nurses, and pastoral counselors. In measuring the public's image, this study uses a semantic differential scale that is composed of 16 pairs of adjective words. In overall, among five helping professionals, social welfare professionals is the most positively recognized; thus, its total score is the highest. By using correspondence analysis, social welfare professionals belong to the second quadrant that includes "practical" and "comfortable". As have discussed in the previous research, however, the analysis reveals that social welfare professionals' expertise is not highly evaluated. On the other hand, ANOVA shows that unlike statistically significant differences between social welfare professionals and other helping professionals, there is no statistically significant difference between social welfare professionals and clinical psychologists. Finally, MANOVA shows that except for gender social demographic variables do not make any differences in the public's image on social welfare professionals. In conclusion, this study discusses diverse directions and measures to strengthen social welfare professionals' competencies including expertise and promote the public's image social welfare professionals.

Therefore the job satisfaction of organizational members should be raised to cut down on their turnover rate. The purpose of this study was to examine the relationship of the general characteristics of radiological technologist-turned hospital managers to their job satisfaction and turnover intention in a bid to identify factors affecting their job satisfaction and turnover intention. The major findings of the study were as follows: First, as for job satisfaction and turnover intention, the radiological technologist-turned hospital managers investigated got a mean of 3.00 and 2.79 respectively on overall job satisfaction and turnover intention out of five points. Their job satisfaction was slightly above the average (2.5), which indicated that they weren't gratified with their job. Their turnover intention was a little above the average as well, which implied that there was a tendency for them to seek another job. The findings of the study seem to suggest that the radiological technologist-turned hospital managers should make a new investment in their own future as their identity was thrown into confusion with age. They are expected to make a preparation for their future to open up a new chapter for themselves instead of being merely contented with their present position.

Caregiving supports have been provided to decrease caregiving burdens of families of children with disabilities, but there are needs for improving caregiving services. The purpose of this study was to conceptualize content items and domains of caregiving supports from the perspectives of parents and service providers in order to help families of children with disabilities to decrease their caregiving burdens. This study used concept mapping that was useful for service-needs identification and program development. First, focus group interviews with two parent groups and one service provider group were conducted to generate a total of 31 items. Also, they sorted the items in terms of conceptual similarity and rated the items in terms of their needs. Next, the sorting data were analyzed using multidimensional scaling and cluster analysis and the rating data were calculated for mean. The results provided 31 content items in four domains: regular caregiving, activity-based caregiving, parent empowerment for caregving, and strengthening family relationships. All the domains were rated as important to decrease caregiving burdens. This study has practical implications for improving caregiving services and the related policies.

This paper presents an analysis of how the business models of organizations are getting transformed in the Marketspace created by the Internet. We use a research model comprising the transformation scores of four Ps(Product, Price, Promotion, and Place) as dependent variables and three dimensions, Demographics, Technology, and Community elements on the Websites, as explaining variables about the Cyber Transformation of the 4Ps. While most existing literatures have focused on Website's technology, our research model includes 22 five-point-scale items; 10 Demographics /Technology items and 12 Community items. To measure the 4P's transformation scores, the authors selected 14 workable items from the Marketspace Model by Dutta, Kwan, & Segev(1997). A sample of 123 shopping mall Websites comprising three categories(grocery, jewelry/accessory, and cosmetics) from the 100hot.co.kr list are evaluated and the data is analyzed by SPSSWIN 8.0 version. The result shows that there are five significant factors, Technology, Interaction, Connectedness, Business Features, and Domain, while the average transformation scores of 4Ps are at very low level. The factor scores are used in regression analysis for each P. Two factors, Technology and Interaction are influencing all four Ps; Connectedness is influencing only two, Product and Place. Organizations must not simply take their existing business models. They have to adopt the Technology items(navigation, logo, e-mail, guide, graphics) and to facilitate the Interaction items(consulting, number/quality of bulletin boards, participation, offline events) and Connectedness(club activation, contents, partner/site link, entertainment contents) in order to get transformed in the Marketspace successfully in the near future.
