This study aims to examine the expressive characteristics and meanings of modern in contemporary fashion, especially focusing on Vogue and The New York Times. First, modern signified originality born out of borderless fusion and compromise. It was also expressed to signify diversity and tolerance not bounded by conventions, TPO, areas, ethnic groups, seasons, or gender. Second, modern meant functionality encompassing the comfort of body and mind. It was used to refer to convenient mobility and activity fit for the lifestyle of busy modern people. Third, lightness and naturalness were used as new meanings of beauty in modern fashion. In the fashion of the twenty-first century, the principal meaning of modern was lightness, which was sought after in everything including materials, modes of wearing, and ways of thinking. Finally, modern fashion was expressed as a democratic tool for social reform and used in the meaning of enlightenment to benefit society as well as oneself. The results of this study indicate that constant changes in trends, lifestyles, and psychology of contemporary society have the potential to give new meaning to the concept and the use of the term modern.

An uncertified facility is a facility not certified, as defined in the Biological Agents and Toxins Act (BATA) in Singapore, but has met the requirements of the Ministry of Health to possess First and Fifth Schedule biological agents and toxins. This type of facility is also known as a Biosafety Level 2 Plus (BSL 2+) facility. Registration as an uncertified facility or a BSL 2+ facility requires a certain process and procedure to be sought with the Biosafety Branch of the ministry. This review, shares first-hand knowledge on the journey to achieving registration of the authors' facility. The procedure involved considerable preparation, setting up facility requirements, biosafety precautions, procedures and practices, and training and competence of laboratory users. The ministry conducted a thorough onsite facility audit to ensure that the facility requirements and biosafety procedures and practices were in place. It then issued an approval letter of possession for the first-time use of biological agents and registered the laboratory as an uncertified facility. The expectation is that the comprehensive information shared may be of great benefit to other facilities with similar interests.

Objectives: Epidemiological evidence linking long working hours and shift work to metabolic syndrome remains inadequate. We sought to evaluate the impact of reducing working hours on metabolic syndrome. Methods: We compared the prevalence of metabolic syndrome among male manual workers in a manufacturing company (N = 371) before and after the introduction of policy to reduce daily work hours from 10 to 8 hours. Components of metabolic syndrome were measured in periodic health examinations before the intervention, 6-9 months after, and 1.5-2 years after the intervention. Generalized estimating equation models were used to estimate changes in the prevalence of metabolic syndrome. Analyses were stratified by day work versus shift work. Results: The results showed a significantly decreased prevalence of metabolic syndrome 6-9 months following the intervention in day workers (risk ratio = 0.68, 95% confidence interval 0.52-0.88), but the benefit disappeared after 1.5-2 years. Shift workers showed a decreased prevalence of metabolic syndrome for the whole follow-up duration after the intervention, although the change was not statistically significant. Conclusion: Reducing working hours was associated with short-term improvement in metabolic syndrome in male manual workers.

This study compared and analyzed parental leave and child allowance, two major policies among solutions to the current serious low fertility rate problem, using unstructured data, and sought future directions and implications for related response policies based on this. The collection keywords were "low fertility + parental leave" and "low fertility + child allowance", and data analysis was conducted in the following order: text frequency analysis, centrality analysis, network visualization, and CONCOR analysis. As a result of the analysis, first, parental leave was found to be a realistic and practical policy in response to low fertility rates, as data analysis showed more diverse and systematic discussions than child allowance. Second, in terms of child allowance, data analysis showed that there was a high level of information and interest in the cash grant benefit system, including child allowance, but there were no other unique features or active discussions. As a future improvement plan, both policies need to utilize the existing system. First, parental leave requires improvement in the working environment and blind spots in order to expand the system, and second, child allowance requires a change in the form of payment that deviates from the uniform and biased system. should be sought, and it was proposed to expand the target age.

The purpose of this study is to explain the benefits of public libraries in Korea. While many studies had focused on measuring the economic value, this study sought to investigate how do user benefits from public library service and how are these benefits associated with major demographic factors. The questionnaire was developed by two question formats, which is open-ended and 5 Likert scale on 'enjoyment indicators' in earlier studies. Total 313 responses data were collected in S public library in Seoul. As a result, respondents most frequently perceived benefits from library services is reading, saving the money and relaxation. Also, user's benefits level had measured based on the 'enjoyment indicators'. According to the analysis, respondents perceived benefits from library for reading (4.31) and saving the money (4.14). The results show the public libraries' benefits differ in age and careers in 'family relations', 'reading of children', 'cultural life', 'career improvement', and 'saving the money'.

Treatment of Leptomeningeal carcinomatosis (LMC) from solid cancers has not advanced noticeably since the introduction of intra-cerebrospinal fluid (CSF) chemotherapy in the 1970's. The marginal survival benefit and difficulty of intrathecal chemotherapy injection has hindered its wide spread use. Even after the introduction of intraventricular chemotherapy with Ommaya reservoir, frequent development of CSF flow disturbance, manifested as increased intracranial pressure (ICP), made injected drug to be distributed unevenly and thus, the therapy became ineffective. Systemic chemotherapy for LMC has been limited as effective CSF concentration can hardly be achieved except high dose methotrexate (MTX) intravenous administration. However, the introduction of small molecular weight target inhibitors for primary cancer treatment has changed the old concept of 'blood-brain barrier' as the ultimate barrier to systemically administered drugs. Conventional oral administration achieves an effective concentration at the nanomolar level. Furthermore, many studies report that a combined treatment of target inhibitor and intra-CSF chemotherapy significantly prolongs patient survival. Ventriculolumbar perfusion (VLP) chemotherapy has sought to increase drug delivery to the subarachnoid CSF space even in patients with disturbed CSF flow. Recently authors performed phase 1 and 2 clinical trial of VLP chemotherapy with MTX, and 3/4th of patients with increased ICP got controlled ICP and the survival was prolonged. Further trials are required with newly available drugs for CSF chemotherapy. Additionally, new LMC biologic/pharmacodynamic markers for early diagnosis and monitoring of the treatment response are to be identified with the help of advanced molecular biology techniques.

Purpose: This study sought to examine whether near total gastrectomy (nTG) confers a longterm nutritional benefit when compared with total gastrectomy (TG) for the treatment of gastric cancer. Materials and Methods: Patients who underwent nTG or TG for gastric cancer were included (n=570). Using the 1:2 matched propensity score, 25 patients from the nTG group and 50 patients from the TG group were compared retrospectively for oncologic outcomes, including long-term survival and nutritional status. Results: The length of the proximal resection margin, number of retrieved lymph nodes and tumor nodes, metastasis stage, short-term postoperative outcomes, and long-term survival were not significantly different between the groups. The body mass index values, and serum total protein and hemoglobin levels of the patients decreased significantly until postoperative 6 months, and then recovered slightly over time (P<0.05); however, there was no difference in the levels between the groups. The prognostic nutritional index values and serum albumin levels decreased significantly until postoperative 6 months and then recovered (P<0.05); the levels decreased more in the nTG group than in the TG group (P<0.05). The mean corpuscular volumes and serum transferrin levels increased significantly until postoperative 1 year and then recovered slightly over time (P<0.05); however, there was no difference between the groups. Serum vitamin $B_{12}$, iron, and ferritin levels of the patients did not change significantly over time, and no difference existed between the groups. Conclusions: A small remnant stomach after nTG conferred no significant nutritional benefits over TG.

Despite its universal coverage of health insurance, the rural health insurance program(RHIP) stands at the crossroads in Korea. The RHIP has weaknesses in stability of financing, problems of inequities in the provision of health services and has suffered from high cost of running the program. The author has analyzed these problems from the perspective of health insurance policy and presented several options for improvement. First of all, this study urged the importance of a firm Governmental commitment of RHIP with the 50% subsidization of contributions as the Government had promised, instead of the current 40%. This can be justified from the 20% subsidization by the Government for the contributions of private school teachers and their dependents, who belong to richer segments of the population. Second, various cost containment measures ought to be sought curbing the rising demand for medical through strengthening health education and increasing individual responsibility, and tightening the claim review process. Third, this study requires the Government to run a demonstration project on the introduction of case payment system for primary health care. Fourth introducing an income-related cost sharing scheme is another possibility. Reforming the cost sharing formula for large medical expenditures is recommendable for a beginning. This measure can take the form of tax credit for medical expenditures of the poor. Fifth, the degree of financial adjustment among health insurance plans should be levelled up for enhancing stability of RHIP and social solidarity. Sixth, health policy should be redirected toward development of rural health resources and higher priority should be put on relieving difficulties in access to care. Seventh. the insurance plan owned-hospital needs to be developed or provision of health services in the medically underserved areas, and the need of such facilities is particularly acute for geriatric care, rehabilitation and renal dialysis, etc. Eighth, more generous insurance benefits are required of the elderly who are suffering the most : elimination of the maximum 180 days of benefit period and provision of glasses and artificial dentures, etc. Ninth. the economies of scale principle is working for the operating expenses of regional self-employed insurance plan. Thus, measures should be instituted to pursue an optimum size of health insurance plans. Lastly, excessive dependence on exclusion items is an evil so that some radical remedies are urgently required to cut them.
