Prior research provides evidence that R&D expenditures contribute to the performance of firms. However, the performance of R&D expenditures is affected by the strategies employed by the firms. This study reviews the relationship between R&D expenditures and company performance in major R&D intensive industries over a 20-year period from 1989-2008. This paper investigates the relationship between R&D performance and company strategy among companies involved in the electric and electronics industry. Samples consist of 25 firms,whose R&D performances and strategies are examined every five years. Three variables are used for classifying strategy types: marketing differentiation strategy, product differentiation strategy, and cost leadership strategy. We developed a technology and value matrix (hereafter referred to as a TnV Matrix) to analyze the relationship between R&D expenditures and the firm`s performance. The TnV Matrix is used in categorizing four types of firm: investment-profit type, profit-seeking type,status quo type, and poor outcome type. We reviewed the trends in company strategies over a 20-year period and identified differences in strategies between successful R&D firms and other firms in each five year period. The results suggest that successful R&D firms implement dominant strategy and differentiation strategy in both product and marketing for the whole period. We found that several firms moved from the “successful category” (investment-profit type) to other categories because their strategies were very simple and inconsistent. The evidence suggests that firms should develop differentiation strategy in both product and marketing for sustainable growth. Our findings suggest that the TnV Matrix is an effective tool for identifying successful R&D firms and analyzing the relationship between their success and the strategies they employ.

The purpose of this study was to understand the labor division between men’s housework and market work and to research the change of men’s contribution to housework. And it was also examined what kinds of valuables work on a change in men’s market work and housework. The information about men’s change in the labor division was collected from the biggest 5 news papers in Korea for last five years for this study. And either men’s new participation trend to household work did. Words searched for this study were men, labor, family, horne, housewife, work, household work, father etc. Korean men have experienced a overloaded breadwinner role and have worked most in the world since 1960s. But Korean men’s working time was continuously decreased a little every year. As Korean Companies had fired many worker during IMF economic crisis period, Korean men had to work more than before because of decreased fellows and they should have concentrated on their work at the sacrifice of private life and family-sharing time. On the other hand, some men were started to participate to do housework as a results of long-unemployment and early retirement after this periods. 5 day working system be in forced gradually since 2003 especially make men come back home and interest on housework. So Korean men’s housework participation is gradually increasing by the practical application of sex-equitable politics such as 5 day working system and men’s suspension regime for baby care. father's increased participation to children education and care, men’s new family-oriented life style, dual-sexuality education system, and socially changed perception to husband housemaker. These interrelated trends demands us to shape a new labor division pattern in the family that make change the breadwinner/homemaker conception by the gender role. Now, all of family, men, women, and children have to join housework It would help women, men, and all families make more human and equitable relationship.

This study was conducted to investigate the prevalence rate for rabies antibody (PRRA) of dogs near the Pukhansan National Park and in some other districts in Seoul Metropolitan city. From April to July 2000, a total of 414 serum samples were taken from dogs for breeding (92), pet dogs (62), and unclaimed/stray dogs (62). Rabies virus antibodies were detected by neutralizing peroxidase-linked assay (NPLA). Of 414 sera tested, 145 (35%) were positive to rabies virus antibody. PRRA in Pukhansan National Park area and in the other districts of Seoul city were 34.8% and 35.4%, respectively. There was no significant difference in the prevalence rate between these two districts. PRRA in pet dogs, unclaimed/stray dogs, and dogs for breeding were 39.5%, 35%, and 27.2% respectively. PRRA in dogs from residential areas, apartments, animal hospitals, and farms were 32.5%, 60%, 35.3%, and 26.7% respectively. Especially, the dogs reared in apartments had a significantly higher seroprevalence (60%) than those in residential or farm areas. PRRA in less than 1 year, 1~<2 years, 2~<3 years, and over 3 years old dogs were 14.7%, 40.4%, 38.4%, and 53% respectively, and overall 35% in the dog population. In addition, we found that dogs less than 1 year of age had lower antibody prevalence than those over 1 year of age. It was concluded that enhancement of vaccination is important in the prevention of the rabies, and that rabies vaccines should not be less supplied than the population of the dog.

This study aims to investigate the predictors of frailty in different age groups. To address this purpose, this study used the 2014 Survey of the Living Conditions of the Elderly (SLCE). In the research model, 4,123 older adults aged 75 and older were included from the SLCE. All participants were subdivided into two age groups based on their age; the young old group (75-85) and the old-old group (85+). The young old group consisted of 1,453 (43%) pre-frail older adults and 1,268 (37%) frail older adults; the old-old group consisted of 304 (40%) pre-frail older adults and 396 (52%) frail older adults. Our regression analysis showed that in the young-old, being female, lower levels of education, having more chronic diseases, having fall experience, higher depression, lower cognitive functioning significantly predicted transition to pre-frailty from non-frail status. In the old-old, being female, higher depression, lower level of social activity were significant predictors. On the other hand, predictors of transition to frailty from pre-frail status in the young-old were being female, higher age, being unemployed, having more chronic diseases, having fall experience, higher depression, lower cognitive functioning. In the old-old, predictors of transition to frailty from pre-frail status were only higher age, having more chronic disease, higher depression, and lower cognitive functioning. The research findings can be used as a reference point in the making of strategies for preventing frailty.

본 연구는 대학생들의 영어 말하기 능력 향상을 목표로 기획 및 운영된 방학 중 몰입 프로그램의 개요를 제시하고, 협동학습이 외국어 불안감에 미치는 영향을 분석하였다. 2019년 K대학에서 4주간 진행된 본 프로그램은 ESL 문법 및 말하기, TOEIC 학습, 소그룹 중심 말하기 활동, 개인학습으로 구성되었으며, 총 40명이 참여하였다. 프로그램 운영 결과, 협동학습을 기반으로 한 교육 방식이 학습자들의 영어 말하기 능력 향상에 긍정적인 영향을 미쳤으며, 외국어 교실 불안척도(FLCAS)를 활용한 사전·사후 조사에서도 ‘의사소통 불안’, ‘시험 불안’, ‘부정적 평가 불안’, ‘외국어 교실 불안’의 네 가지 영역에서 전반적인 불안감 감소가 확인되었다. 특히, 소그룹 활동을 통한 자발적 참여와 협력적 학습 환경이 ‘부정적 평가 불안’과 ‘의사소통 불안’을 낮추는 데 효과적이었음이 나타났다. 본 연구는 국내에서 진행되는 영어 몰입 교육이 해외 연수와 유사한 효과를 거둘 수 있음을 시사하며, 향후 보다 체계적인 협동학습 적용 및 지속적인 연구의 필요성을 제언한다. This study outlines the planning and implementation of an intensive English program aimed at improving university students’ speaking skills and examines the impact of cooperative learning on foreign language anxiety. Conducted at K University in 2019, the four-week program consisted of ESL grammar and speaking lessons, TOEIC preparation, small-group speaking activities, and self-directed learning, with a total of 40 participants. The results indicate that the cooperative learning approach positively influenced students’ English-speaking proficiency. Pre- and post-program assessments using the Foreign Language Classroom Anxiety Scale (FLCAS) revealed reductions in four key areas of language anxiety: communication anxiety, test anxiety, fear of negative evaluation, and classroom anxiety. Notably, small-group activities fostering active participation and collaborative learning were particularly effective in reducing fear of negative evaluation and communication anxiety. The findings suggest that domestic intensive English programs can achieve outcomes comparable to overseas language immersion programs and highlight the need for further research on structured cooperative learning methods.

In this paper, PLC which can be installed easily and is stable to transfer datum, is tested for approving its application in a real ship. Internet access service, CCTV monitoring, light control and huge sensor communications are needed for enhancing the convenience and safety of passengers and crew in ships. In order to apply PLC in ships, we surveyed some noises interrupting PLC in ships and investigated the PLC characteristics. The Hannara, a training ship of Korea Maritime University, was used for the test. We measured and analyzed blocking noises using by NI's SCXI-1001. When noises of specific frequency band occurred near the PLC frequency band, PLC transfer capacity was low for mass datum. We developed and verified some methods to apply PLC in a ship under lots of noises.
