  • The present study reviewed the study on the impact of divorce upon children's well-being presented in both abroad and Korea. The criteria for the selection of the study for the review are as follow; The study must have a comparative child group of non-divorced family and include at least one psychological variable that are measured quantitatively. Two studies are found in Korea and 92 in abroad. Both the domestic studies and foreign studies indicate the lower self-esteems of children of divorced families than those of children of non divorced families. In domestic study, the sociable was found as the variable that give a negative impact to the children of divorced families among elementary population but not to the children of middle school. In contrast, the studies of foreign showed the negative impact of the seven psychological variables included in the studies upon children of divorced families. The study suggests that the impacts of divorce on the children will be more pronounced in Korea than in abroad and the necessities of the studies in the future in Korea.

  • Purpose: To examine the degree of recognition regarding the concept of patient safety, as perceived by the patient, using a focus group discussion. Methods: A focus group discussion was conducted with a patient group comprising seven patients. Results: When the participants heard the term "patient safety" they seemed to understand it to be related to the hospital environment or satisfaction with the overall hospitalization experience. The participants emphasized communication between the medical staff and the patients in relation to the explanation of treatments, as well as the provision of information regarding prevention, experience, and the treatment of incidents with patient safety. They agreed on the need for indicators reported by patients. However, they emphasized that additional items and a questionnaire method that considers the patients' point of view are needed. Conclusion: It is necessary to establish and implement various strategies that can raise the awareness of patient safety using patient safety indicators and increase participation in patient safety activities.

  • 超硬合金과 高速度鋼에 TiC, TiN 그리고 $Al_2O_3$의 耐 마모 코우팅시에 사용되는 CVD와 PVD 기술을 M E Sjostrand와 A G Thelin 등이 본 논문에서 논의하였다. 또한 CVD와 PVD 의 특별한 장점과 응용영역에 대하여도 토의하였다. 수년동안 CVD 기술은 금속질화물, 금속탄화물 그리고 금속산화물 등의 耐 마모 코우팅을 생산하는데 성공적으로 사용되어 왔다. Munster와 Ruppert에서는 1950년대 초기에 TiC와 TiN의 CVD 공정을 연구했는데 이런 코우팅 재료의 높은 화학적 안정성과 더불어 高硬鋼라는 독특한 성질로 인해 그 주요 영역이 명백해졌다. 1968년에 처음으로 CVD법에 의한 보호막 코우팅의 대규모 응용이 이루어졌는데 그것은 超硬合金 절삭공구의 코우팅이었다. (그림1 참고) 이것은 硬금속산업에 있어서 가장 중요한 발전단계였다. TiC, TiN 그리고 $Al_2O_3$로 코우팅된 공구의 생산은 1970년대에 빠른 성장을 보였으며 오늘날 사용되는 절삭날의 50% 이상을 점유하고 있다. (그림2 참고) TiC와 TiN은 현재 이용되고 있는 모든 耐 마모 코우팅 중에서 독보적인 위치를 차지하고 있다. 그 이유는 생산과정이 비교적 단순하기 때문이다. 지난 5년동안 절삭공구와 總形바이트의 코우팅에 대한 PVD기술의 응용이 폭발적으로 증가했다. 증착기술인 이들 CVD와 PVD 각각은 자체의 독특한 장점이 있으므로 그 응용영역은 증착조건, 즉 기지금속의 접착성과 증착온도 그리고 증착속도등에 따라 매우 다를 것이다. PVD 공정으로 인해 고속도 공구강이 급속도로 발전되었고 더우기 PVD공정은 500$^{\circ}C$ 이하의 증착온도에서 brazed carbide 공구의 코우팅을 가능하게 하였다. 따라서 두 증착기술은 서로 상반적이라기 보다는 상호보완적인 것이라고 생각하는 편이 더 좋다.TEMPLA에 비해 CLB의 수가 15.58% 감소되었다. 높은 활성을 나타내었다. 정제된 효소의 최적온도는 40$^{\circ}C$이었으며 20~50$^{\circ}C$에서 비슷한 활성을 나타내었고, 30$^{\circ}C$에서는 60분동안 효소활성이 거의 상실되지 않았다. 정제된 효소는 ethanol과 chloroform 처리에는 안정하였으나 12mM AT 와 0.1mM $NaN_3$ 및 1mM KCN에 의해 90% 이상의 활성이 억제되었다.이에 근거하여 서울시 학생들($7{\sim}18$세)의 만성신부전증 유병률은 1백만명당 5.7명으로 추정되었다. 결론 : 서울시내 학생들 중 11세, 14세, 17세 3개 군에서 한 번 검사로 확인된 무증상 단백뇨의 유병률은 0.28%(약 2.8명/1,000명)이었고 이들중 약 5%만이 3차검사에서 신질환이 의심되었으며 이에 따른 신질환 유병률은 1만명당 1.4명이었다. $7{\sim}18$세 연령층에서 무증상으로 발생하는 사구체 신질환 중에는 IgA 신병증의 유병률이 가장 높아 1만명당 0.64명으로 추정되었고 만성신부전증의 유병률은 1백만명당 5.7명으로 추정되었다. 집단뇨 검사를 통해 확인되는 신질환은 대부분 사구체 질환이기 때문에 집단뇨검사의 의의는 좀더 연구가 필요할 것으로 생각되었다. 오히려 증상을 동반하는 경우보다 빈도가 증가한다는 사실은 집단뇨 검사에서 소변의 이상소견이 발견되어 신장 조직검사를 실시할 경우 혈청 $C_3$치의 감소 여부에 관계없이 MPGN도 진단적 고려 대상이 되어야 한다고 생각한다.신장 조직검사를 시행한 결과 진행성 경과를 취할 수 있는 막 증식성 사구체 신염과 매우 희귀한 증례인 신유전분증 등으로 진단됨으로써 지속성 단백뇨의 경우 정확 진단적 접근이 필수적임을 알 수 있다. 기립성

  • The purpose of this study was to investigate the effect of organizational culture (group culture, development culture, rational culture, hierarchical culture) on job satisfaction based on the mediating effect of organizational trust on workers corporations. In particular, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. The results of the study of 8,615 workers in the manufacturing, financial, and non-financial industries in HCCP(Human Capital Corporate Panel) are as follows. First of all, the result of research showed that rational culture, group culture, development culture among organizational culture had a positive effect on job satisfaction. But, the hierarchical culture had a negative influence on job satisfaction. Second, rational culture, group culture, development culture among organization culture had a positive effect on organizational trust. But, hierarchical culture had a negative influence on organizational trust. Third, in the relationship between organizational culture and job satisfaction, the partial mediating effect of organizational trust was verified. In other words, although organizational culture directly affects job satisfaction, it indirectly affects job satisfaction through organizational trust. Fourth, it showed a significant moderating effect of communication between organization trust and job satisfaction. In other words, it was found that the group with high organizational trust in the relationship between organizational trust and job satisfaction had higher job satisfaction than the group without it. Finally, in the relationship between organizational culture and job satisfaction, the mediating effect of organizational trust was demonstrated, which varies by communication control variables. In other words, the indirect effect of organizational culture on job satisfaction through organizational trust is higher in the group with high communication capabilities. Through discussion and conclusion, the academic and practical implications, limitations, and research directions of this study were presented.

  • This study aims to provide a science history content system necessary in the course design process of liberal arts subjects, along with the application of flip learning in liberal arts science classes for humanities and social sciences students. For the research, we analyzed the current state of the liberal arts and history of science classes at universities. Then we developed the 'Understanding the History of Science' subject by applying the flip learning method through the analysis of various previous studies. As the goal of science history lectures that can reach the essential purposes of science liberal arts education, including knowledge acquisition and strengthening various competencies, scientific attitude cultivation was set, and the content system of week 15 was designed to consider this. The four topics corresponding to the "History of Science" part of the "Understanding Science History" content system consisted of flipped learning classes and teaching and learning activities, including online video materials and group discussion activities. As a result of opening courses for students in the humanities and social sciences and operating classes for 56 college students, it was confirmed that students' interest and awareness of science increased. This study provides educational evidence for science history and liberal arts education.

  • Specialty stores, which have been major channels of Korean cosmetic industry, are bringing out a lot of problems in current distribution channel systems because of its repeated depression of sales. Especially, inefficiency in distribution channel systems is caused by cannibalistic price-off competition between specialty stores, too many launchings of new products, excessive sales promotion, absence or surplus of stock, and so on. Using qualitative methods such as in-depth interview and group discussion, the authors attempt In diagnose fundamental problems of the cosmetic specialty store distribution channels in three viewpoints; achievement of goals, marketing flows in channels, and relationship management. In addition, this paper suggests core strategies for building up the competitiveness of both of the maker and the retailer, The competitive strategies are mainly about securing profitability of retailers, smoothening of marketing flows in channels, and building-up trustful relationships between distribution channel members.

  • Widespread recognition of the various aspects of science education has been prompted by post-positivist philosophers' discussions of the nature of science and intense debates among constructivist psychologists about learning in science. Their discussions and debates, in turn, have raised the problems associated with teaching/learning of science in the schools. The purpose of this article, basically based on the reviews and analyses of the literature related to philosophy of science and psychology, was to describe the implications of post-positivism and constructivism for current science education in the schools. In this paper, the author defines science education as education of/about science, and education through/by science. He also stresses that scientific literacy and decision-making should be emphasized as the goals of science education, that the ethical dimensions of science and technology must be included in science curriculum, that group discussion and/or cooperative learning are effective teaching strategy for science as interpreted by post-positivists and constructivists, and that the assessment should be focused on the degree to which cognitive structure has been changed through instruction in the school classrooms.

  • Problem Based Learning(PBL) is one of effective teaching-learning strategy for enhancing military students' motivation, comparing with the other study method. After monitoring military student classes, we conclude that PBL can enhance the effectiveness of learning in War history case study education and finds merits; PBL assists students to play a more active role in the class, induces students to solve problems independently, and makes the learning military situation real case study. The case study is common in social sciences and life sciences. Case studies may be descriptive or explanatory. It is good for War history education. The demerit of PBL is a costly method as students should spend more time and institutions should provide more manpower and materials. This study suggests that more empirical researches on alternative teaching methods, including PBL, to a lecture in War history education.

  • Site-index curves for Pinus densiflora Sieb. et Zucc. grown in the middle part of Korea were developed from stem analysis data by a procedure of guide curve equation $Yt=K-ab^t$ (t=0, 1, 2, ${\cdots}{\cdots}$) and shown in Fig. 2. The stand density expressed as size-number criteria was calculated and the relation of number of tree per hectare and average DBH was presented in Fig. 3, in which soil fertility showed little effect. When this is compared to Reineke's density standards, the Pinus densiflora stand ranks high level of stocking density (Fig. 5). As a measure for estimating timber volume, the angle-summation technique revealed to result wider variation. Constructing hypothetical populations for appraising angle-summation technique, the significance of its application in silvicultural and ecological research are discussed.
