이 연구는 1인가구가 계속 증가하는 현상과 함께 1인가구를 주제로 한 연구가 축적되어야 한다는 필요성 그리고 사회적으로 워라밸(일-생활 균형)에 대한 관심에 주목하여 취업 1인가구의 일-생활 균형 실태를 파악하고자 수행되었다. 1인가구 중에서 미혼 20-30대 11명을 대상으로 심층면접을 통해 1인가구로서의 일상생활, 일-생활의 실태 그리고 일-생활 균형과 관련된 사례 분석을 실시하였다. 연구 결과, 1인가구로 살게 될 때의 자발성, 1인가구 삶에 대한 준비와 계획 등은 1인가구 삶에 대한 만족도에 영향을 미치는 중요한 요인으로 나타났다. 자기계발이나 여가활동에 있어서 돈과 시간이라는 자원의 영향이 크다는 점도 확인할 수 있다. 가족과의 소통과 교류에서, 직접적인 대면은 충분치 않지만 메신저 사용을 많이 하고 있으며, 떨어져 사는 가족 특히 부모님과의 관계에서 경제적, 정서적, 가사노동의 상호 지원이 이루어지고 있음을 알 수 있다. 또한 참여자들은 직장생활을 경험하면서 일-생활 균형의 중요성을 더욱 인식하게 되었고, 일과 대비되는 생활의 영역에서 자기계발, 여가활동의 의미가 부각되고 있다. 또한 일-생활 균형의 장애요인으로 업무부담 외에 돈과 시간이라는 자원의 제약을 발견할 수 있다. 일-생활 균형을 위해서 경제적 지원 그리고 유연근무제와 같은 제도에 대한 요구가 나타났다. 이러한 결과를 통해 1인가구로서의 삶을 준비하고 계획하는 데 도움을 주는 가정경영 및 가족자원관리 교육의 필요성을 확인할 수 있다. 나아가 다양한 집단의 일-생활 균형을 위해 맞춤형의 사업과 제도가 활성화될 필요가 있을 것이다.

본 연구에서는 기혼자 22명을 대상으로 심층면접을 통하여 기혼자의 '결혼'에 대한 인식을 살펴보았다. 심층 면접 자료를 분석한 결과는 다음과 같다. 1. 기혼자들은 결혼을 통해 얻는 것이 있으면 잃는 것이 있다는 양면을 잘 인식하고 있었다. 즉 결혼을 하면서 잃어버린 자신의 세계에 대한 동경이 있고, 자유로웠던 싱글 시기를 그리워하고 아쉬워하지만, 반면에 결혼을 통해 안정감과 소속감을 얻게 되었고 외롭지 않다고 한다. 2. 기혼자들은 결혼은 경험하지 않으면 모르는 세계라고 인식한다. 싱글은 인생의 간만 보는 것이라면 결혼은 인생의 맛을 보는 것이라고 인식한다. 기혼자들이 결혼의 삶에서 찾아나가는 '맛'은 '가족과 자식의 힘', '인생 고비 뒤의 나를 찾아가는 길', '함께 하는 삶의 즐거움과 편안함', '넓어지는 삶의 폭, 높아지는 삶의 질'이다.

Acinetospora asiatica and Botrytella reinboldii are reported as two new records from S. Korea based on morphological studies and molecular analyses. A. asiatica is mainly characterized by the presence of sparsely branched uniseriate filaments with diffused meristematic zones, the formation of crampons at right angles, and the formation of plurilocular sporangia on both prostrate and erect filaments. B. reinboldii is characterized by the presence of irregularly alternating branched uniseriate filaments attached by rhizoids, and single or clustered plurilocular sporangia with a single opening. Molecular analyses of rbcL gene revealed that A. asiatica and B. reinboldii are placed within each clade of Acinetospora and Botrytella, respectively.

In South Korea, social, the number of single-person households has rapidly increased because of financial factors. Since single-person households have characteristics differentiated from general households, many enterprises pay attention to them that appear as important consumers. This study conducted a survey with consumers in their 20s to 50s in single-person households, nationwide who had an experience of purchasing HMR. The results of this study can be summarized as follows: First, of the benefits pursued in dietary life, the pursuit of nutrition a negative (-) impact on RTH type and did not have any impacts on the RTE and RTC types. The pursuit of taste had a positive (+) impact only on the RTE type while it did not have any impact on the RTH and RTC types. The pursuit of convenience had positive (+) impacts on all RTH, RTE and RTC types, while the pursuit of price sought did not have any impact on all types. Second, of the preferences by each HMR type, preferences for the RTH and RTC types had positive (+) impacts on purchase intention while preference for the RTE type did not have any impact on purchase intention. Third, of the benefits pursued in dietary life, the pursuits of taste and convenience had positive (+) impacts on purchase intention while the pursuits of nutrition and price did not have any significant impacts on purchase intention. In addition, of the benefits pursued in dietary life, the pursuit of convenience had a significant impact on purchase intention mediated by preference by each HMR type. As a result, taste of HMR and the aspects of convenience act as factors inducing purchases, and products in the various forms of taste and convenience in order to appeal consumers who pursue taste and convenience.

The pharmacokinetics of CJ-50001 (recombinant human granulocyte-colony stimulating factor, developed by R&D center of Cheil Jedang Corp.) were investigated in rats and dogs. The serum concentrations of CJ-50001 were measured by a sandwich enzyme immunoassay. After single intravenous (iv) administration of Cf-50001 to rats at a dose of 5 $\mu$g/kg, the mean terminal half-life and area under the concentration-time curve (AUC) were 0.96 h and 124.497g . h/ml, respectively. After single subcutaneous (sc) administration at the same dose, maximum serum concentration was observed at about 2 hours after administration, and the mean terminal half-life, AUC and the bioavailability were 1.11 h,63.58$\mu$g . h/ml and 51.07%, respectively. In repeated dosing studies, CJ-50001 was administered iv and sc to rats at a daily dose of 5$\mu$g/kg for 7 days. The pharmacokinetic parameters, such as mean AUC and terminal half-life, were no significantly different from those of single administration. Following single iv and sc administration of CJ-50001 to dogs at a dose of 5 $\mu$g/kg, mean AUCs were much higher than those of rats, due to the decreased clearence (CL). After sc administration to dogs, maximum serum concentration was observed at 2~4 hours after administration and the bioavailability was 54.60%.

Purpose: The aim of this study was to evaluate the effects of tailored case management using a gatekeeper on depression and life satisfaction in the single-household elderly population. Methods: The design of Quasi experiment was applied to compare the variables before and after the management. Ninety-seven people who had depression categorized by the Korean Geriatric Depression Scale. Results: Depression (t=11.22, p<.001) and life satisfaction (t=-5.36, p<.001) were improved after management in comparison to the results of pre-tests, and the differences were statistically significant. The difference in the pre-test and post-test scores of the support system ($x^2$=13.89, p<.001) were significant, while the differences in the perception of depression ($x^2$=.02, p=.891) and coping methods ($x^2$=.34, p=.558) were not statistically significant. Conclusion: Tailored case management using a gatekeeper is effective to reduce the degree of depression and improve life satisfaction in the single-household elderly population having depression. This study offers a model of individualized as well as systemic mental health care for the community of single-house hold elderly people as an effective means for prevention of and early intervention in depression.

To identify genes involved in the decolorization of crystal violet, we isolated random mutants generated by transponson insertion in crystal violet-declorizing bacterium, Citrobacter sp. The resulting mutant bank yielded mutants with six distinct phenotypes, and Southern hybridization with a Tn5 fragment as a probe showed a single hybridized with six distinct phenotypes, and Southern hybridization with a Tn5 fragment as a probe showed a single hybridized band in the mutants Ctg 2, 5 an 6, whereas two and three bands were detected in Ctg1, 4 and 3, respectively. Tn5-inserted genes were isolated and the DNA sequence flanking Tn5 was determined. From comparison with a sequence database, putative protein product encoded by ctg 5 was identified as E. coli maltose transproter(Mal G) homolog, whereas the deduced amino acid sequence of the other ctg genes did not show any significant similarity with any DNA or protein sequency. Therefore, these results indicate that the other ctg genes except ctg 5 encode new proteins responsible for decolorization of crystal violet.

The purpose of this study is to offer basic data of education to improve farm lives though investigating rural homemakers' life style. The results of this study are as follows : 1. The life structure of rural homemakers was classified into two structures as a material resources and human resources. The life style of rural homemakers was classified into systematical life style, traditional value style, social active style, and progressive active style. 2. The life styles of rural homemakers according to social population variance were as follows. The lower of age, homemakers whose family incomes more 30 million won or below 10 million won, who has religions, who employed in livestock were showed at very systematical life style. The homemakers who live in mountain village, higher the much age becomes, and the education level become lower, have showed traditional value style. Rural homemakers the lower of age, the higher incomes, composed of single parent ＋ children who remain single were appeared social active style. Rural homemakers the lower of age, the more shortened farm life periods, who employed in livestock were appeared progressive active style. 3. Systematical life style was more affected by material resources structure, traditional value style was affected by material resources. And social active style was more affected by human resources, progressive active style was affected by human resources.

1인 가구의 비율은 꾸준히 증가하고 있으며, 청년층의 비율은 35.9%로 전체 1인 가구 중 가장 많은 비율을 차지한다. 하지만 청년 1인 가구에 대한 연구가 활발히 이루어진 것은 비교적 최근이다. 1인가구에 대한 연구는 대부분 1인 가구 전체 또는 노인 1인 가구에 집중되어 있는 실정이며, 더 나아가 연령층별 차이 및 비교에 관한 연구는 부족하다. 따라서 본 연구는 전체 1인 가구를 청년층과 중장년층, 노년층으로 나누어 세 집단의 주거만족도에 영향을 미치는 요인에 어떤 차이가 있는지 확인하고 이러한 주거환경요인이 주거만족도의 매개효과를 통해 삶의 만족도에 어떠한 영향을 미치는지 확인하고자 한다. 분석에는 2020년 서울서베이 도시정책지표조사 데이터를 활용하였으며, 구조방정식 모형을 이용해 각 요인들의 영향관계를 분석하였다. 본 연구의 첫 번째 결과는, 다양한 주거환경요인들이 주거만족도와 삶의 만족도에 직접적인 영향을 미치는 것으로 나타났다. 다음으로 청년 및 중장년 1인 가구 모형에서 주거만족도가 삶의 만족도에 직접적인 영향을 미치는 것으로 나타났다. 이를 통해 주거만족도에 영향을 미치는 주거환경요인에는 차이가 있음을 확인하였으며, 주거만족도가 중요한 매개 역할을 한다는 사실 또한 확인하였다. 마지막으로 다른 연령층에 비해 청년층의 주거 및 삶의 만족도에 영향을 미치는 요인이 더 다양한 것으로 나타났다. 본 연구의 정책적 시사점은, 1인가구의 주거 및 삶의 만족도 제고를 위해서는 연령층별 차이가 우선적으로 고려되어야 한다는 것이다. 특히 청년 1인가구의 경우에는 주거 및 삶의 만족도 향상을 위해 더 다양한 대안을 고려해야 할 필요가 있다.

Since the surface roughness of adherends affects much the strength of adhesivelybonded joints, the effect of surface roughness on the fatigue life of adhesively bonded tubular single lap joints was investigated analytically and experimentally by fatigue torsion test. The stiffness of the interfacial layer between adherends and adhesive was modeled as a normal statistical distribution function of surface roughness of adherends. From the investigation, it was found that the optimum surface roughness of adherends for the fatigue strength of tubular single lap joints was dependent on bondthickness and applied load.
