Objectives: To identify the relationship between the internet addition of elementary school students, and their health behavior and VDT syndrome, and thereby to detect the impact of internet addiction on the health behavior of elementary school students, to get the basic information necessary to develop a prevention program for internet addiction and to plan for VDT syndrome prevention program. Methods: We conducted this study during the period from jun 27, 2007 through July 8, 2007. The subjects of this study were 416 children whose grades were in 4th through 6th grades of elementary schools located in the city A in Kyung Pook Providence. Data were obtained from self-rating questionnaires. The questionnaires were composed of Korean Internet Addiction Self-examination on Internet Use Patterns (K-scale), Health Behavior Profile, VDT Syndrome, and general characteristics. We used t-test, AVOVA with Ducan method for Post-hoc comparison in means comparison between groups, $X^2$-test for frequency analysis and Pearson's correlation coefficient. We used SPSS/PC(12.0 ver) program and the LISREL 8.53 Win program for covariance structural analysis. Results: Major results were as follows. 1. The internet addiction propensity distribution based on the distribution of scores were investigated according to the self diagnosis scale on internet addiction. 6.5% of them were high risk user group, 14.4% were potential risk users and 79.1% of them were common user groups. 2. Internet addictions by sex, internet use duration, frequency (days/week), time(hours/day), purpose, position, brightness of internet, attitude of parents and frequency of conversation of family members were statistically significant(p<0.01). 3. There was a statistically significant difference in VDT syndrome according to internet addiction groups(p<0.001) besides ocular symptoms, dry mouth and GI troubles. 4. The health behavior score was the lowest in high risk user group(p<0.001). There were significant differences between internet addiction groups in personal hygiene and habits of daily living(p<.002), the prevention of accidents(p<.002), the practice concerned with the prevention of infectious disease(p=.002), and mental health(p<.001). 5. There was also a significant negative correlation between internal addiction and health profile(r=-0.365, p<0.01) and a significant positive correlation between internal addiction and VDT syndrome(r=0.331, p<0.01). 6. As the result of structural model analysis, internet use time(/day), days of internet use(/1week), conversation frequency among family members, degree of brightness of internet use had significant direct effects on internet addiction. Conclusions: The results will help the development of an effective intervention program for the prevention and treatment of internal addiction by clarifying the effect of the internal addiction upon elementary school students' VDT syndrome and health behavior.

현대는 산업 문명의 발달로 시장의 세계화가 급속히 진행되고 있다. 비슷한 품질과 서비스를 제공하는 수많은 기업들은 각기 다양한 방법으로 자사의 제품을 차별화하며 보다 많은 시장점유율과 매출액, 이윤을 창출하기 위하여 부단한 노력을 기울이고 있다. 이 중에서 가장 대표적인 것이 자사의 브랜드를 강력하게 만틀어 관리하는 일이다. 현대의 소비자는 상품을 사지 않는다. 그들은 복잡한 설명서도 읽지 않으며, 가격으로 물건을 평가하지도 않는다. 단지 자신의 머릿속에 각인된 브랜드를 선택한다. 브랜드는 오늘날 고도의 마케팅 전략의 핵심 도구로 취급되고, 또한 중요한 법적 자산으로 평가되고 있다. 따라서, 기업의 마케터들은 자사 제품의 가치를 높이기 위한 수단으로서 브랜드 자체의 명성을 구축하는 데 심혈을 기물이고 있다. 유명하고 좋은 이미지를 가진 브랜드만이 충성 스러운 고객기반을 확보할 수 있고 가격 경쟁에서 유리한 위치를 점할 수 있으며 안정된 수 익을 확보할 수 있기 때문이다. 이와 같이, 브랜드는 비록 무형적이지만 제품이 가진 어떤 유형적인 특성보다도 중요하게 생각되고 있는 것이다- 단순히 생산자나 제품을 구별하는 수단을 넘어 중요한 자산으로 인 식되고 있으며, 이러한 맥락에서 브랜드 자산가치의 개념이 만들어 진 것이다. 본 연구는 브랜드 자산가치의 형성에 미치는 영향요인으로서 내부마케팅 요인, 마케팅믹스 요인, 브랜드수의 증가요인의 3가지 요인을 설정하여 설문조사를 통한 판매자의 평가 결과로 어떤 요인이 어느 정도의 영향을 미치는지를 분석하였다. 본 연구에서 나타난 결과를 요약하면 내부마케팅요인(조직구성원간의 직무만족, 조직구성 원간의 원활한 커뮤니케이션), 마케팅믹스요인(제품 품질, 가격정책, 유통전략, 광고 및 홍보 활동), 브랜드수의 증가요인(시장환경의 불투명성, 시장진입의 선발감)이 모두 다 브랜드 자산가치의 형성에 영향을 미치는 것으로 나타났다.

Paragonimiasis typically results from the consumption of raw or improperly cooked crustacea, especially crabs and crayfish. Although previously endemic in Korea, the prevalence of this disease decreased in the early 1970s because of educational campaigns and fewer intermediate hosts as a result of ecological changes. Recently, we were presented with a family where all members were infected with Paragonimus after ingestion of Kejang (= drunken crab). The mother was hospitalized for general myalgia and weakness first, followed by the father, who was hospitalized for dyspnea 2 month later. After the parents were diagnosed with paragonimiasis, we recommended their daughter to visit our hospital for a checkup, because they all had eaten freshwater crabs soaked in soybean sauce. She complained of generalized myalgia, fever, and pleuritic pain, and was also diagnosed with paragonimiasis. Peripheral blood of the 3 patients revealed hypereosinophilia, and computed tomography (CT) scans of their chests showed pleural effusion. The results of antibody tests by ELISA were positive for paragonimiasis. We report here the case series of familial paragonimiasis in a modern urban city, rather than in a typical endemic area.

Respiratory infections are very common and highly contagious. Respiratory infectious diseases affect not only the person infected but also the family members and the society. As medical sciences advance, several diseases have been conquered; however, the impact of novel infectious diseases on the society is enormous. As the clinical presentation of respiratory infections is similar regardless of the pathogen, the causative agent is not distinguishable by symptoms alone. Moreover, it is difficult to develop a cure because of the various viral mutations. Various respiratory infectious diseases ranging from influenza, which threaten the health of mankind globally, to the coronavirus disease 2019, which resulted in a pandemic, exist. Contrary to human expectations that development in health care and improvement in hygiene will conquer infectious diseases, humankind's health and social systems are threatened by novel infectious diseases. Owing to the development of transport and trading activity, the rate of spread of new infectious diseases is increasing. As respiratory infections can threaten the members of the global community at any time, investigations on preventing the transmission of these diseases as well as development of effective antivirals and vaccines are of utmost importance and require a worldwide effort.

The purpose of this study was to recognize the self - efficacy and organizational citizenship behavior. For the reliability and validity of the questionnaire, exploratory factor analysis was performed and the Cronbach's s value was calculated to determine the internal consistency of the questionnaire. The effect of organizational culture of self - efficacy on organizational citizenship behavior was as follows. First, it was analyzed that individual culture, collective culture, hierarchical culture, and rational culture had a significant effect on self - efficacy. Second, self-efficacy had an important effect on organizational citizenship behavior. Third, individual culture and rational culture had a significant effect on organizational citizenship behavior. However, the collective culture and hierarchical culture, which put emphasis on family relations and teamwork, had no significant effect on organizational citizenship behavior respectively. Therefore, it is found that the group culture which valuesfamily-friendly and feamwork of its members,or the hierarchical citure for adapting to the external environment has no effect on organizational citizenship behavior family-friendly and lay emphasis on the teamwork of the organization members, and it does not have an effect on the organizational citizenship behavior.

The objective of this work is to study the restraining effect in fire resistance of framed structures and to evaluate the global response of reinforced concrete frames when exposed to fire based on advanced finite element method. To study the response a single portal frame is analyzed. The effect of floor slab on this frame is studied by modeling a beam-column-slab assembly. The evolution of temperature distribution, internal stresses and deformations of the frame subjected to ISO 834 standard fire curve for both the frames are studied. The thermal and structural responses are evaluated and a comparison of results of individual members and entire structure is done. From the study it can be seen that restraining forces has significant influence on both stresses and deflection and overall response of the structure when compared to individual structural member. Among the various structural elements, columns are the critical members in fire and failure of column causes the failure of entire structure. The fire rating of various structural elements of the frame is determined by various failure criteria and is compared with IS456 2000 tabulated fire rating.

The effective management of knowledge has become one of the critical success factors in current organizations. In spite of the extensive use of Knowledge Management System (KMS), useful information and knowledge resources are still transmitted through personal networks among people in organizations. Thus, social network theory which focuses on social relationships in organization can be a fruitful theoretical resource for enhancing Knowledge Management (KM) performances. In this study, we investigate the effects of intra-team network characteristics (i.e., group density and degree of centralization) and external boundary spanning activities on knowledge management performances of a team. We also acknowledge that all group members do not necessarily agree on the team goal and actively disseminate useful information and knowledge. Drawing on the political perspective on KM which emphasizes the role of trust among group members, we examine the mediating effects of team trust between internal/external network characteristics and KM performances. From the data of 220 teams in financial companies in Korea, we found that: (1) group density had positive effects on KM performances (i.e., knowledge creation, sharing, and use). (2) However, centralization was not significantly associated with KM performances. (3) Team trust was found to be an important factor mediating the relationship between intra-team network characteristics, boundary spanning activities, and KM performances. Based on these results, we discuss and suggest possible implications of the findings when designing and implementing KM practices.

Yielding of the internal steel reinforcement is an important mechanism that influences the Intermediate Crack-induced debonding (IC debonding) behavior in FRP-strengthened RC members since the FRP is required to carry additional forces beyond the condition of steel yielding. However, rational design practice dictates an appropriate limit state is defined when steel yielding is assured prior to FRP debonding. This paper proposes a criterion which correlates the occurrence of IC debonding to the formulation of a critical steel yielding length. Once this length is exceeded the average bond stress in the FRP/concrete interface exceeds its threshold value, which proves to correlate with the average bond resistance in an FRP/concrete joint under simple shear loading. This proposed IC debonding concept is based on traditional sections analysis which is conventionally applied in design practice. Hence complex bond stress-slip analyses are avoided. Furthermore, the proposed model incorporates not only the bond properties of FRP/concrete interface but also the beam geometry, and properties of steel and FRP reinforcement in the analysis of IC debonding strength. Based upon a solid database, the validity of the proposed simple IC debonding criterion is demonstrated.
