In ordo to investigate the professional job perception and job satisfaction of interns and residents and its related factors, the author conducted survey using self administered questionnaire for 2 months(August and September, 1996). The study subjects were 562 interns and residents who worked at one university hospital(tertiary hospital) and two general hospitals(secondary hospital) in Taegu, Korea. Among them, 297 (52.8%) responded completely. The results were as follows ; Respondents thought that people component was most important, science and status components were next among professional value scales which meant the desirable attitudes required to conduct professional works. But, the score of professional value scales was generally high and not affected by other variables in multiple linear regression analysis. They seemed to have very normative and ideal perceptions about professional values. The score of professionalism scales, which were attitudinal and behavioral traits about professional job, of high grade residents was significantly higher than that of interns and lower grade residents. The score of reference to professional organization and autonomy factor were increasing significantly as the grade increased. Working conditions and perception for socioeconomic status of doctors influenced the score of professionalism scale significantly. It seemed that professional socialization was made during the training periods of interns and residents. Most of respondents answered that current socioeconomic status of doctors were middle and high strata but they responded that the socioeconomic status of doctors would fall in the future. They seemed to have a pessimistic thought about doctor's status. Generally the respondents thought that they were satisfied with doctor job and fit to the job, but 51.9% answered that if possible they would get other jobs. It seemed to reflect their critical thinking on doctors' status. Perceptions about socioeconomic status of doctors, professional value and professionalism influenced job satisfaction significantly. The interns and residents had high sense of calling to doctors and thought that doctors were socially important job. Generally they were satisfied with their job. Interns and residents had normative thoughts about the trait which compentent doctors must have. During the training period, they seemed to have attitude and perception as a professional and to make professional socializations.

Purpose: The purpose of this paper is to analyze a sample of single corridor, pod type and composite type of ICUs in terms of patient visibility, spatial configurations and nurse walking distance focused on Korean cases. Methods: The measures of static visibility were used to quantify the patient visibility (upper third part of the patient bed) from the nurse station. The measure of space programme and area distribution (patient zone percentage, staff zone percentage, circulation zone percentage, corridor length per bed, distance from nurse station (NS) to patient bed and departmental gross square meter (DGSM) per patient bed) were calculated by using AutoCAD and MS Excel programs. In the second step of analysis the values of space distribution were compared among the three type of ICUs as well as the nurse walking distance, DGSM per bed and gross factor. in the third step of analysis regression analysis was conducted for the possible correlation between visibility and space programme and area distribution factors as well as nurse walking distance factors. Results: (1) It was found that on average composite type unit offer highest value of patient visibility followed by pod type, while single corridor type unit offers the minimum value of patient visibility among the three plan typologies. (2) Average patient visibility and DGSM per bed shows a strong positive correlation ($r^2=0.75$) and p=0.026. (3) Average patient visibility and average distance from NS has a strong negative correlation ($r^2=0.78$), and P=0.02. (4) On average composite type unit offer the minimum walking distance from NS (7.22 meter) followed by pod type unit (8.35 meter) and single corridor (9.76 meter). (5) Maximum distance from NS was noted in single corridor (18.19 meter) followed by pod type unit (15.14 meter) and Composite type unit (11.1 meter). Implications: This study may contribute to the visibility analysis of existing and future ICU design in Korea to achieve maximum patient visibility and reduced nurse walking distance.

NF-κB는 염증과 선천성 면역에 중요한 전사인자이며 anti-apoptotic gene을 유도하여 세포의 생존과 발암에도 깊이 연관되어 있으며 많은 신호전달분자 및 신호전달회로와 연결되어있다. 한편, Hsp90는 NF-κB의 활성을 조절한다는 보고가 이루어졌으나 그 구체적인 기전은 알려져 있지 않다. 본 연구에서는 IKK compelx를 구성하는 인자들의 발현 plasmid를 이용하여 NF-κB의 활성조절에서 Hsp90와 IKKγ의 연관성 및 역할을 연구하였다. 그 결과 Hsp90는 IκBα의 인산화와 분해를 촉진하여 NF-κB를 활성화시켰고, NIK과 LPS에 의한 NF-κB의 활성화는 Hsp90에 의해 더욱 활성이 증가하였다. IKKγ는 Hsp90에 의해 증가된 IκBα의 인산화와 분해를 더욱 촉진함으로써 Hsp90의 NF-κB 활성화 작용을 상승시켰다. 이러한 Hsp90와 IKKγ에 의한 NF-κB의 활성화 현상은 항상 활성화 된 상태를 유지하는 IKKβ-EE mutant를 이용한 검토에서도 입증되었다. 또한 IKKγ의 deletion mutant를 이용한 검토에서 IKKγ의 N-말단에 위치하는 IKKβ 결합부위와 C-말단에 위치하는 leucine zipper 및 zinc finger 부위는 IKKγ와 Hsp90의 NF-κB에 대한 상호협력적 촉진작용에 필요하지 않았다. 또한 Hsp90에 의해 촉진된 세포내 pro-inflammatory cytokine들의 발현은 IKKγ에 의해 더욱 상승하였다. 이러한 결과로부터 Hsp90와 IKKγ의 상호작용을 차단한다면 NF-κB의 과다활성으로 인한 질병의 예방과 치료에 도움을 줄 수 있을 것으로 사료된다.

In this research, food waste source reduction model for apartment was investigated. In spite of prohibition of direct landfill of food waste and continuous efforts made by government and local government, food waste production increases steadily. Recycling ratio of the food waste increases every year, but its products have many problems like low quality, stability, salt, odor etc. Household occupies 63.3% of whole food waste production and this is subject to be a key factor to control food waste. We surveyed S apartment in Kwangju city as a model case, in which administrative office and women's association adopted clean plate eating, separation of raw food waste and earth worm composting as a series of method for source reduction and recycling inside the apartment. With the help of residents' participation and practice, food waste production decreased 15.6% from 0.31 g/capita/day in 2007 to 0.26 g/capita/day in 2009 (domestic average 0.30 g/capita/day). Separation of raw food waste and its composting using earth worm were very effective, and were subject to resolve the problems of present food waste treatment technologies. And earth worm composting was very useful in environmental, economical, societal and educational aspects. Instead of economical incentive, educational programs about food value, environmental problem and critical method for food waste separation were more effective for promotion of source reduction. From the analyses on the process and success factors in this model, we could conclude that leader's role was one of the key factors for the settlement of source reduction, and that was to understand the seriousness of the food waste and to seek solution, to test techniques, and to practice by oneself. Furthermore, networking and collaboration among residents, local government, NGO and local press promoted residents' participation, and it was through various education and investigation. Finally, source reduction and self recycling model of food waste in the apartment, that applies separating raw food waste and earth worm composting based on the collaboration among residents, local government, NGO, and local press, should be disseminated, and environmental policy also should be changed to make it possible.

By the middle of 2018 there are signs of China's entry into a new period of development, characterized by a change in the old model: "market reforms-inner-party democratization - moderate foreign policy" to another: "market reforms - Xi Jinping personality cult - offensive foreign policy." This model contains the risks of arising of the contradiction between economic freedom and political-ideological rigidity which can lead to destabilization of the political life. However, in the current positive economic dynamics, these risks may come out, rather, in the medium and long term. Today, the political situation in China remains stable - despite growing dissatisfaction in scientific expert and educational circles due to increased control over the intellectual sphere by the authorities. The need for a new redistribution of power between central and provincial authorities could potentially disrupt political stability in the medium term, but, at the moment, is not a critical negative factor. The economic situation is positive-stable. Forecasts indicate a possible increase in China's GDP in 2018 at 6.5%. At the same time, there are negative expectations in connection with the Sino-US and potentially Sino-European "trade war". In the Chinese foreign policy, as a response to Western pressure, China increasingly uses the Russian direction of its diplomacy in the expanded version of Russia + SCO. The nuance here is seen in China's adjusted approach to the SCO: first of all, not as a mechanism for cooperation with Russia, but as an organization that allows using Russia's potential for pressure on the US in the Sino-US strategic rivalry. In the second half of 2018, the Chinese economy will continue to develop steadily, albeit with unresolved traditional problems (debts of provinces and state-owned enterprises, ineffective state sector, risks on the financial and real estate market). In politics, discontent with the cult of Xi will accumulate, but without real threats to its power. Weakening in economic opposition between China and the United States is possible due to Beijing's search for compromises on tariffs, intellectual property, trade deficit. To find such trade-offs, Xi will use the so-called. "Personal diplomacy" of direct contacts with Trump.

Purpose - The perception of the quality of the consumer's distributor's brand(PBs) is generally perceived to be lower than that of the manufacturer's brand(NB), although it is a critical factor in determining the success of PBs. Accordingly, this study examines the characteristics of the convenience store PB products and their correlation with brand trust and purchase intent in the consumers who have had experience purchasing the convenience store PBs to expand the sales variables. Further, this research shows that the marketing strategy is to increase the share of PBs by providing an empirical analysis on the effect of the product attribute factors on the sales volume associated with brand trust, purchase intent, and others. Research design, data, and methodology - The survey period of this study was approximately three weeks from December 1, 2017 to December 21, 2017. The study samples that were taken from 100 random people extracted. The statistical analysis was carried out with multiple regression analysis using the SPSS statistical package. Results - The analysis shows that the brand credibility and purchasing intention were statistically significant differences between the private convenience store private brand products. Specifically, brand trust showed a statistically significant relationship the brand images and quality levels, but the perceived value was not affected statistically. Although the intent of the purchase showed a statistically significant relationship the quality level and the perceived value, the brand image was not statistically significant in its relationship. Conclusions - Overall, it has been established that the perception value does not statistically affect brand trust for convenience store PB products, and that the brand image has no statistically significant effect on the purchase intent. These results are analyzed to be due to the influence of brand in convenience stores themselves rather than brand trust and purchase intentions that affect sales performance, which is the property of private brand food and beverage products, the perceived value of their products. Accordingly, the study found that not only did the marketing performance of the convenience store PB products be improved statistically, but also the cause of the product attributes that were not statistically significant was identified.
