  • The walls of all higher plants are organized as a cellulosic, fibrillar phase embedded in a matrix phase composed of non-cellulosic polysaccharides, some proteins and, in most secondary walls, lignin. At the effective utilization of plant biomass, qualitative and quantitative analyses of plant cell walls are essential. Structural features of individual components are being clarified using newly developed equipments and techniques. However, "empirical" procedures to elucidate plant cell walls, which are not due to scientific definition of components, are still applied in some fields. These procedures may give misunderstanding for the effective utilization of plant biomass. In addition, interesting the investigation of wall organization is moving towards not only qualitatively characterisation, but also quantitation of the associations between wall components. These involve polysaccharide-polysaccharide and polysaccharide-lignin cross-links. Investigation of the associations is being done in order to understand the chemical structure, organization and biosynthesis of the cell wall and physiology of the plants. Procedures for qualitative and quantitative analyses based on the definition of cell wall components are reviewed focussing in nutritional elucidation of forage grasses by ruminant microorganisms.

  • 현대사회가 정치, 경제, 사회를 포함한 모든 분야에서 전문화되고 복잡해지면서 일반적인 공권력으로는 범죄를 통제하기 어려운 상황에 이르렀다. 19세기 이후 요동치기 시작한 민간보안 산업은 그 범위를 넓혀 공권력이 필요한 다양한 분야에서 보조적인 역할을 수행하고 있다. 이러한 민간보안 활동 중에서 민간조사시스템은 오랫동안 개인의 인권보호와 범죄로부터 안전한 민간조사 서비스를 제공하는 데 이용되어 왔다. 이 연구에서는 선행연구 분석과 질적 내용분석을 통해 실종자 조사 시스템에 초점을 맞춘 영국과 한국의 민간조사 시스템을 비교분석 할 것이다. 질적 내용 분석의 결과는 영국의 민간조사시스템과 실종자 조사시스템이 어떻게 구현되는지에 대한 문헌 검토 및 심층면담 등의 방법을 통해 기술된다. 민간조사 분야에 대한 연구는 양국에서 매우 중요한 분야이지만 한국의 시각에서 볼 때 그 연구가 매우 제한적이라고 할 수 있다. 따라서 이 연구는 민간조사 시스템의 성공적인 합법화를 위한 논의를 촉진할 뿐만 아니라 향후 연구의 기초자료가 될 것으로 기대된다. 민간조사 시스템의 연구는 앞으로도 지속적으로 이루어져야 한다. 또한 한국에 민간조사제도를 도입하기 위해서는 본 연구에서 언급한 민간조사제도와 관련된 문제점을 발견하여 민간, 학계, 관련 기관의 의견을 수렴해 민간조사시스템을 개발해야 한다. 민간조사제도의 도입은 민간, 학계 및 관련 기관의 노력을 통해 이익을 극대화시킬 것으로 사료된다.

  • 과학적이고 합리적인 화재조사 및 수사를 위해서는 화재조사 전담부서의 설치가 시급하고, 화재조사원의 충분한 확보와 이들의 전문성 강화가 필요하며, 화재감식 연구시설의 확충이 절실히 요구된다. 또한 화재조사업무의 신뢰성 확보를 위해서는 화재피해산정을 정확히 하도록 최선을 다해야 하며, 대외발표창구를 일원화해야 할 것이다. 그리고 방화 및 실화범에 대한 사회적 관심이 너무 부족하였다. 앞으로 이에 대한 많은 연구와 제도적 개선이 필요하다고 본다. 집행유예의 선고시 부과할 수 있는 수강명령 등을 방화 및 실화범에게 적용하여 소방시설 및 안전교육 등을 받게 함으로써 재범을 방지하는 등의 사회적 노력과 예방 관리적 프로그램이 요망된다.

  • This qualitative study delves into consumers' meanings, perceptions, and behaviors toward the anthropomorphism of fashion goods based on personal experiences. Previous studies focused on consumer responses to the marketer-driven anthropomorphism of products, messages, and brands; however, the present study examines consumers' spontaneous anthropomorphism focusing on personal meanings as a possessor and meanings in their social relationships. A qualitative methodology is adopted that involves in-depth interviews with eleven males and females in their 20s and 30s. Participants stated that were engaged in the anthropomorphic practice of fashion goods on a daily basis. Data analysis was based on grounded theory. Findings on consumer-driven anthropomorphism are discussed at personal and interpersonal levels. At the personal level, anthropomorphic objects are their companions that are often called "baby." Interestingly, anthropomorphism reduces the stigmas of materialism from the participants' side. At the interpersonal level, anthropomorphic practice is a ritual of sharing a common interest and assuring intimacy. Implications and suggestions for future research are also discussed.

  • This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

  • One of the major health problems of working women is job stress according to many studies. However, existing job stress questionnaires are suitable for men and men's job environments only, and do not reflect emotional labor for sales people. The aim of this research is to find women's job stress factors. The subjects of this investigation are married working women in sales since they experience emotional labor in addition to physical and psychological labor and the work-family conflict is very important job stressor for them. The job stressor of married sales women was analyzed through qualitative research. After I had in-depth interviews with 20 married sales women, I identified 49 new concepts, 3 main categories and 17 sub categories. The results are like the following. 1. 3 main categories are job factor, aggravate factor, and compensate factor. 2. Job factor has 5 sub-categories including 'increasing of selling', 'emotional labor' and 'physical burden'. 3. Aggrabate factor has 6 sub-categories including 'work/family conflict', 'relationship with higher office' and 'relationship with a fellow worker' 4. Compensate factor has 6 sub-categories including 'opportunity of employment', 'discrimination', and 'prestige' Consequently this study newly found some major job stressors for married working women in sales department.

  • A review of taxonomic treatments of the amentiferous plant taxa reveals diverse classification. It appears to be necessary to investigate new characteristics and attempt to determine the significance of these characteristics in terms of amentiferous systematics. Serological techniques have been empolyed in a systematic investigation of selected taxa of the Amentiferae: Betulaceae, Fagaceae, Juglandaceae, Myricaceae, and Salicaceae. Data by qualitative analysis of pollen proteins, double immunodiffusion and conventional immunoelectrophoresis, have proved to be valuable in delimitation of taxa tested. When the antisera against Alnus hirsuta, Betula platyphylla var. japonica, Quercus aliena, Q. dentata, Q. glauca were tested; Alnus and Betula have the greatest protein similarity to one another; and next to the rest of betulaceous genera. Relatively strong protein similarity obtained with most representatives of Quercus and Fagus when reacted with antisera against Alnus and Betula is very much in contrast to the weak protein similarity obtained for the genera of Juglandaceae, Myricaceae, particularly of Salicaceae Tested with the same antisera. When Quercus antisera were used for various genera, the weakest protein similarity was obtained with Populus.
