This study examined the fashion culture of 20-30s working women through clothing norm relationships in the workplace. A literature research was conducted along with qualitative research, in-depth interviews in order to understand the domestic working environment and fashion culture such as lifestyle and consumer culture characteristics of 20-30s working women. The results were: First, it showed that the increased number of members having various inclinations caused subcultures through an increase of women's economic activities and transition to a knowledge-information society in domestic work places that changed into a business casual that recognized employees' autonomy and diversity. Second, in the working place, clothing norms coexist as stipulated by statutes, company rules, and official documents as well as others implied by experiences of sanction against members. Workplace closing norms are classified into norms of exposure that draw attention to clothes and casual clothes. Third, it showed that factors pressuring clothing norms are classified as external pressures and by spontaneous self-censorship that cause conflict and confusion with working women's fashion according to the degree of pressure. Two kinds of pressure by others (or types of departments and members) were observed.

The bisexuality deconstructivity and diversity that are great characteristics on the comtemporary fashion are showed in the fashion collections. The purpose of this paper is to investigate and analyze the influence of these characteristics made by the post modern-feminism fashion through the cultural pattern analysis. The post modern-feminism was analyzed by dividing the cultural pattern into 1) the deconstructivity of androcentrism -This characteristic was presented in the costume design that breaks the basic from of the line color and quality of the material showing in men's clothes. 2) By rejecting main current fashion -Subculture style appeared in main current fashion the boundary of main and anti-main current fashion was vagued and the phenomena that the identity of subgroup was weakened were showed. 3) In the coexistence of double-sided value -This characteristic was presented in the cross-dressing fashion that cut away women's slender part and men's rough part. 4) In the open-minded thought of gender -This tendency was reached an extreme from excessive exposure to design which gives the sexual stimulus. This paper is expected to be helpful to understand the contemporary fashion by treating the cultural category associated with post-modern feminism in relation to contemporary fashion and to establish the direction of 21 century fashion.

Daphne pseudomezereum var. koreana is an endangered deciduous shrub distributed in mountain areas that is vulnerable to climate change. The purpose of this study was to provide foundational data on the physical characteristics, soil environment, and vegetation structure of habitats of Daphne pseudomezereum var. koreana habitat in Korea in order to help with management decisions on ecosystem restoration. Rock exposure was 15 to 35%, with an average of 24%. The native habitat of D. pseudomezereum included 129 taxa consisting of 46 families and 95 genera. Two-way cluster analysis divided the habitat into three plant communities: Community I (dominaterd by Tilia amurensis and Quercus mongolica), Community II (dominaterd by Fraxinus rhynchophylla and Acer pseudosieboldianum), and Community III (dominaterd by Ulmus davidiana var. japonica). The diversity indices for Communities I, II, and III were 1.124, 1.047 and 0.932, respectively. The soils were loam or clay loam. Soil pH, organic matter content, and available phosphoric acid were 5.40, 14.38%, and 31.08 ppm, respectively. Ordination analysis resulted that most significant factors influencing D. pseudomezereum distribution were magnesium content of soil, shrub layer, and altitude.

The expansion of information sharing activities using online can increase the threat of information exposure by increasing the diversity of approaches to information within an organization. The purpose of this study is to present conditions for improving the information security compliance intention of insiders to improve the level of information security within the organization. In detail, the study applies the theory of planned behavior that clearly explains the cause of an individual's behavior and proposes a way to increase the compliance intention by integrating the social control theory and goal-setting theory. The study presented research models and hypotheses based on previous studies, collected samples by applying a questionnaire technique, and tested hypotheses through structural equation modeling. As a result, information security attitude, subjective norms, and self-efficacy had a positive influence on the intention to comply. Also, attachment, commitment, and involvement, which are the factors of social control theory, formed a positive attitude toward information security. Goal difficulty and goal specificity, which are the factors of goal setting theory, formed a positive self-efficacy. The study presents academic and practical implications in terms of suggesting a method of improving the information security compliance intention of employees.

In the past few decades, great progress has been made on understanding the interaction between nutrition and health status. But despite this wealth of knowledge, health problems related to nutrition continue to increase. This leads us to postulate that the continuing trend may result from a lack of consideration for intra-individual biological variation on dietary responses. Precision nutrition utilizes personal information such as age, gender, lifestyle, diet intake, environmental exposure, genetic variants, microbiome, and epigenetics to provide better dietary advices and interventions. Recent technological advances in the artificial intelligence, big data analytics, cloud computing, and machine learning, have made it possible to process data on a scale and in ways that were previously impossible. A big data platform is built by collecting numerous parameters such as meal features, medical metadata, lifestyle variation, genome diversity and microbiome composition. Sophisticated techniques based on machine learning algorithm can be used to integrate and interpret multiple factors and provide dietary guidance at a personalized or stratified level. The development of a suitable machine learning algorithm would make it possible to suggest a personalized diet or functional food based on analysis of intra-individual metabolic variation. This novel precision nutrition might become one of the most exciting and promising approaches of improving health conditions, especially in the context of non-communicable disease prevention.

Cadmium (Cd) is a prevalent environmental contaminant that poses a potential hazard to the health of both humans and animals. In this study, biosynthesized selenium-enriched Lactobacillus plantarum and selenium nanoparticles (SeNPs) were developed and evaluated for their protective effects against Cd-induced hepatic injury in mice through oral administration for 4 weeks. Cadmium exposure resulted in severe impairment of liver function, as evidenced by increased levels of serum markers of liver injury and, oxidative stress and significant damage to liver tissue, and a notable decrease in the diversity of the intestinal microbiota. Oral administration of Se-enriched L. plantarum (LS) reduced cadmium accumulation in the liver by 49.5% and, restored other cadmium-induced damage markers to normal levels. A comparison of the effects with those of L. plantarum (L) and SeNPs isolated from LS revealed that LS could more effectively alleviate hepatic oxidative stress and reduce the intrahepatic inflammatory responses of the liver, further protecting against cadmium-induced liver injury. These findings suggest that the development of LS may be effective at protecting the liver and intestinal tract from cadmium-induced damage.

The experimental exposure of animals to sources of ultraviolet radiation (UVR) which emit their energy primarily in the UVB region (280-320nm) is known to result in a number of well-described changes in the recipient's immune competence. Two such changes include a depressed capacity to effectively respond immunologically to transplants of syngeneic UVR tumors and a markedly reduced responsiveness to known inducers of delayedtype (DTH) and contact hypersensitivity (CH) reactions. The results of experiments that were designed to elucidate the mechanisms responsible for UVR-induced immunomodulation have implicated: 1) an altered pattern of lymphocyte recirculation, 2) suppressor T cells(Ts), 3) deviations in systemic antigen presenting cell (APC) potential. 4) changes in the production of interleukin-1-like molecules, and 5) the functional inactivation of epidermal Langerhans cells in this process. The exposure of skin to UVR, therefore, causes a number of both local and systemic alterations to the normal host immune system. In spite of this seeming complexity and diversity of responses, our recent studies have established that each of the UVR-mediated changes is probably of equal importance to creating the UVR-induced immunocompromised state. Normal animals were exposed to low dose UVR radiation on their dorsal surfaces under conditions where a $3.0\;cm^2$ area of skin was physically protected from the light energy. Contact sensitization of these animals with DNFB, to either the irradiated or protected back skin, resulted in markedly reduced CH responses. This was observed in spite of a normal responsiveness following the skin sensitization to ventral surfaces of the UVR-exposed animals. Systemic treatment of the low dose UVR recipients with the drug indomethacin (1-3 micrograms/day) during the UVR exposures resulted in a complete reversal of the depressions observed following DNFB sensitization to "protected" dorsal skin while the altered responsiveness found in the group exposed to the skin reactive chemical through directly UVR-exposed sites was maintained. These studies implicate the importance of EC as effective APC in the skin and also suggest that some of the systemic influences caused by UVR exposure involve the production of prostaglandins. This concept was further supported by finding that indomethacin treatment was also capable of totally reversing the systemic depressions in CH responsiveness caused by high dose UVR exposure (30K joules/$m^2$) of mice. Attempts to analyze the cellular mechanisms responsible established that the spleens of all animals which demonstrated altered CH responses, regardless of whether sensitization was through a normal or an irradiated skin site, contained suppressor cells. Interestingly, we also found normal levels of T effector cells in the peripheral lymph nodes of the UVR-exposed mice that were contact sensitized through normal skin. No effector cells were found when skin sensitization took place through irradiated skin sites. In spite of such an apparent paradox, insight into the probable mechanisms responsible for these observations was provided by establishing that UVR exposure of skin results in a striking and dose-dependent blockade of the efferent lymphatic vessels in all peripheral lymph nodes. Therefore, the afferent phases of immune responses can apparently take place normally in UVR exposed animals when antigen is applied to normal skin. The final effector responses, however, appear to be inhibited in the UVR-exposed animals by an apparent block of effector cell mobility. This contrasts with findings in the normal animals. Following contact sensitization, normal animals were also found to simultaneously contain both antigen specific suppressor T cells and lymph node effector cells. However, these normal animals were fully capable of mobilizing their effector cells into the systemic circulation, thereby allowing a localization of these cells to peripheral sites of antigen challenge. Our results suggest that UVR is probably not a significant inducer of suppressor T-cell activity to topically applied antigens. Rather, UVR exposure appears to modify the normal relationship which exists between effector and regulatory immune responses in vivo. It does so by either causing a direct reduction in the skin's APC function, a situation which results in an absence of effector cell generation to antigens applied to UVR-exposed skin sites, inhibiting the capacity of effector cells to gain access to skin sites of antigen challenge or by sequestering the lymphocytes with effector cell potential into the draining peripheral lymph nodes. Each of these situations result in a similar effect on the UVR-exposed host, that being a reduced capacity to elicit a CH response. We hypothesize that altered DTH responses, altered alloresponses, and altered graft-versus-host responses, all of which have been observed in UVR exposed animals, may result from similar mechanisms.

본 연구는 고온기 여름철 사육환경에서의 홀스타인종 젖소의 반추위내 미생물 균총 변화를 분석하고, 반추위내 미생물과 고온 스트레스간의 연관성을 규명하고자 수행하였다. 국립축산과학원 낙농과에서 사육 중인 홀스타인 젖소 10두의 반추위액을 채취하였으며, 채취한 시료 샘플은 PowerSoil® DNA Isolation Kit (Cat. No. 12888, MO BIO)를 이용하여 DNA를 추출한 후 Illumina HiSeq^TM platform (Illumina, CA, USA)을 이용하여 미생물 균총 분석을 실시하였다. 반추위액 내 미생물 균총을 분석한 결과, 사육환경 온습도에 따른 미생물 군집 구성에는 큰 차이는 없었으나, 미생물의 상대적 함량에는 차이가 있었다. LEfSe 분석을 통해 적온과 고온 환경에서 특정 미생물들의 상대적 조성이 유의적으로 증가함을 확인하였다. 이들 결과를 볼 때, 반추위내 미생물 균총은 고온과 같은 외부 환경변화에 영향을 받는 것으로 판단되어 젖소의 고온스트레스 반응에 있어 반추위 미생물 변화가 중요한 역할을 담당할 것으로 사료된다. 추후 연구는 이러한 차이를 나타내는 미생물들의 대사 경로나 대사 물질에 분석을 통해 환경변화와 미생물간의 연관성 및 이러한 미생물 균총 조절을 통한 고온기 젖소의 적응성 향상을 위한 미생물학적 전략 연구가가 필요할 것으로 생각된다.

본 연구는 뉴스미디어의 의제설정 기능이라는 이론적 배경을 바탕으로 한국 공중의 중요한 사회적 의제(MIP)와 이러한 MIP의 중요성에 대한 공중의 사회적 합의 수준을 시기별로 그리고 다양한 사회계층별로 분석하였다. 주요 분석결과를 보면, 우선 한국 공중들의 MIP는 주로 경제, 시화복지, 그리고 정치 관련 이슈들이 큰 비중을 차지하고 있는 것으로 나타났다. 또한 공중의제의 일치 정도를 알아볼 수 있는 의제의 다양성분석(H-statistic)에서는 일정한 변동의 폭에도 불구하고 장기간에 걸쳐 상당히 높은 의제일치 정도를 보여주었으며, 이는 미국 공중의 의제일치 정도와 비교했을 때 상대적으로 높은 것으로 판단된다. 나아가 한국 공중의 의제다양성은 과거에 비해 어느 정도 줄어들고 있는 것으로 관찰되었으며, 이러한 감소는 다양한 사회계층에서 나타나는 전반적인 현상으로 보인다. 그러나 교육수준, 경제수준, 그리고 거주 지역에 따른 여러 사회계층들 사이에서 상이한 의제다양성이 관찰되었는데, 즉 교육수준이 증가할수록, 사회경제적 수준이 높을수록, 그리고 거주지역의 단위가 클수록 보다 높은 의제일치현상이 관찰되었다. 이런 결과는 해당 변인들과 미디어노출이라는 요인 간의 정적인 관계에 어느 정도 기인하는 것으로 추측된다. 공적 의제들의 중요성에 대한 한국 공중의 높은 사회적 합의수준에도 불구하고, 교육, 경제력, 그리고 거주지역 등에 따른 차별적인 합의의 정도는 공적 이슈에 대한공중들의 인식에 미치는 다양한 사회적 영향들에 대한 후속적인 탐구의 필요성을 제기하고 있다.
