By analyzing five in-depth case studies of suppliers in newly emerging Vietnam's motorcycle industry, this paper explores the differences in patterns and processes of capability improvement of suppliers who participate in different kinds of supplier-assembler network with different structures. The paper finds the correlation between the kinds of suppliers' capabilities improved and the structure of networks they participate in. While suppliers in arm-length networks can improve more upstream capabilities (structure design, process desist), suppliers in embedded networks can improve more downstream capabilities (process design, process setup, process maintenance and delivery control). Two capability improvement patterns of firms in newly emerging economy are indicated. The first pattern is asymmetrical improvement, either upstream or downstream capabilities, by participating in either arm-length or embedded networks. This pattern obstructs the suppliers to meet the requirements of new buyers rho come from different kinds of network. The second pattern is symmetrical improvement by joining both arm-length and embedded networks.

SPR(Self-Piercing rivet) is mechanical element of joining sheet metal components without the need for pre-punched or pre-drilled holes. Newly designed SPR is developed for high joining strength and shearing strength than semi-tubular rivet. In this study, divided shank of self-piercing rivet were designed for joining DP440 and SILAFONT. Newly designed SPR was simulated by using FEM code DEFORM-3D. In simulations of SPR process, various shape of self-piercing rivet were considered for semi-tubular and newly designed SPR. In other to examine the joinability, joining load and lap-shear load of newly designed SPR were compared with semi-tubular by simulated results and experimental ones.

Recent trend of rapid growth in the basic research activities in East-Asian newly industrialized countries bring about the change in the world knowledge production structure. Particularly, Korea showed the changing patterns not only in the number of publication, but also in the aspect of structural change of basic research activities. The stylized facts of basic research activities in Korea can be summarized in three aspects; first, selective development patterns, second, reverse pattern of evolution, and finally, the rapid growth of basic research activities in major firms. This paper analyse the evolutionary patterns of basic research activities in empirical base and propose the policy implication for supporting basic research activity in newly industrializing countries.

The purpose of this study was to investigate factors influencing role adaptation in newly employed nurses and the consistency between role expectations before employment and after one year of employment. The results of this study may contribute to strategy development towards positive role adaptation in newly employed nurses. The data used in this study were collected from 111 nurses, the sample was drawn from all newly employed professional nurses working at Y Medical Center in 1987. The data were collected longitudinally in the 2nd - 3rd weeks, the 3rd month and the 12th month after employment. The results of this study were as follows : 1. The degree of change the importance of factors influencing role adaptation and the length of time after employment were investigated. the result showed that the degree of change was the greatest within the first 3 months after employment. Important factors related to role adaptation were working conditions, the environment of the assigned ward and the work load. These factors always displayed high scores without any great change over time. New employees put more importance on practical factors which were obtained through experience in their jobs rather than on ideal factors Which they had considered more important while in school. 2. Consistency between role expectation before employment and after 12 month of employment was investigated. The highest consintency item was the expectation about the variety of Patients, and the highest inconsistency was the expectation about their own welfare. An average score of 69.07 points was achieved from a maximum of 125 points for the 25 items. showing that expectations for role development before employment were not fully satisfied. In conclusion the administraor should assess the initial expectation at the time of employment of new nurses and she / he should make clear to the new nurses that these expectations may not be realistic. In this way the administrator can provide more satisfactory conditions towards the expectations of the new nurses and help them towards positive role adaptation and reduction of role conflict. Newly employed nurses have high and unrealistic expectations about socialization to the profession from their nursing educational program. It is suggested that a transitional training program should be planned and carried out for newly employed nurses.

Purpose: This study aimed to analyze the impact of increasing the supply of newly licensed nurses on improving the hospital nurse staffing grades for the period of 2009~2014. Methods: Using public administrative data, we analyzed the effect of newly licensed nurses on staffing in 1,594 hospitals using Generalized Estimating Equation (GEE) ordered logistic regression, and of supply variation on improving staffing grades in 1,042 hospitals using GEE logistic regression. Results: An increase of one newly licensed nurse per 100 beds in general units had significantly lower odds of improving staffing grades (grades 6~0 vs. 7) (odds ratio=0.95, p=.005). The supply of newly licensed nurses increased by 32% from 2009 to 2014, and proportion of hospitals whose staffing grade had improved, not changed, and worsened was 19.1%, 70.1%, and 10.8% respectively. Compared to 2009, the supply variation of newly licensed nurses in 2014 was not significantly related to the increased odds of improving staffing grades in the region (OR=1.02, p=.870). Conclusion: To achieve a balance in the regional supply and demand for hospital nurses, compliance with nurse staffing legislation and revisions in the nursing fee differentiation policy are needed. Rather than relying on increasing nurse supply, retention policies for new graduate nurses are required to build and sustain competent nurse workforce in the future.

Glycyrrhizae radix, commonly known as licorice, is a perennial herb belonging to Leguminosae and also includes various components such as, glycyrrhizin, liquiritin, liquiritigenin and isoliquiritigenin etc. Licorice has been widely used in East Asia as a medicine having pharmacological effects like antioxidants, anti-bacterial, anti-inflammatory, anti-cancer and immune modulatory activities. Among various licorice, Glycyrrhiza (G.) uralensis G. glabra and G. inflata are used for pharmaceutical purposes in Korea. However, cultivation of licorice has some problems such as low quality, low productivity, and early leaf drop. Korea Rural Development Administration developed new cultivars Wongam and Sinwongam, which are improved in cultivation and quality. To register the newly developed cultivar (s) on Ministry of Food and Drug Safety in Korea as a medicine, it is necessary to prove the similarity and difference through the comparative studies between already-registered species and new cultivars. Some fungi and bacteria usually in the human oral cavity and intestines exist as harmless state in human body. Also, the skin and genital infections by fungi can lead to toxic systemic infections and are accompanied by flushing, rashes, burning or painful sensation. The influences of licorice varieties on fungi and bacteria might be an evidence to prove the outstanding effect of newly developed licorice variety. In this study, the antifungal and antibacterial activity was investigated using newly developed licorice varieties Wongam, and Sinwongam against various fungi and bacteria. These results means newly developed licorice could be used as a replacement of already-registered species in terms of antifungal and antibacterial application.

최근 대량의 텍스트 분석을 위해 딥 러닝(Deep Learning)을 활용하는 연구들이 활발히 수행되고 있으며, 특히 대량의 텍스트에 대한 학습 결과를 특정 도메인 텍스트의 분석에 적용하는 사전 학습 언어 모델(Pre-trained Language Model)이 주목받고 있다. 다양한 사전 학습 언어 모델 중 BERT(Bidirectional Encoder Representations from Transformers) 기반 모델이 가장 널리 활용되고 있으며, 최근에는 BERT의 MLM(Masked Language Model)을 활용한 추가 사전 학습(Further Pre-training)을 통해 분석 성능을 향상시키기 위한 방안이 모색되고 있다. 하지만 전통적인 MLM 방식은 신조어와 같이 새로운 단어가 포함된 문장의 의미를 충분히 명확하게 파악하기 어렵다는 한계를 갖는다. 이에 본 연구에서는 기존의 MLM을 보완하여 신조어에 대해서만 집중적으로 마스킹을 수행하는 신조어 표적 마스킹(NTM: Newly Coined Words Target Masking)을 새롭게 제안한다. 제안 방법론을 적용하여 포털 'N'사의 영화 리뷰 약 70만 건을 분석한 결과, 제안하는 신조어 표적 마스킹이 기존의 무작위 마스킹에 비해 감성 분석의 정확도 측면에서 우수한 성능을 보였다.
