The purpose of this study was to investigate the effects of ultraviolet (UV) treatment on the hydrophilic properties and removal of particulate soils from microfiber fabrics. A nylon/polyester microfiber knit fabric was irradiated by UV with different treatment times upto 90 min. The hydrophilic properties such as sediment time and contact angle were increased gradually with increase of UV treatment time. However, wicking and water adsorption rate decreased with increase in UV treatment time, which resulted in damage of capillary channel on fabrics. UV treated and untreated fabrics were soiled with carbon black and washed by Launder-O-meter at $40^{\circ}C$ with 40 rpm. In order to assess degree of soil removal, following analysis was carried out to remove soils on the fabrics: surface reflectance, K/S was measured to quantify the amount of remaining carbon black and $\alpha-Fe_2O_3$. The deposition behavior of carbon black on UV treated/untreated fabrics has been also investigated. The soils were more efficiently removed with the increase of UV treatment time.

Carisoprodol (CSP) is commonly prescribed as a skeletal muscle relaxant. Recently, we encountered 7 suicidal cases in which carisoprodol was detected. We developed a rugged, sensitive, and specific method for the determination of CSP and meprobamate (MPB) by GC and GC/MS. Postmortem blood concentrations of CSP and MPB ranged 22.9-124.4 ,$\mu$g/ml and its metabolite, 26.8-144.5 ,$\mu$g/ml respectively. Among 7 cases studied, Only CSP was ingested in 4 cases and combination of CSP and dextromethorphan was ingested in 2 cases according to the case history and one case was with ethanol. The order of the tissue concentration of CSP and MPB was liver> kidney > brain, and the concentration of MPB was higher than that of CSP in all tissues. The MPB /CSP concentration ratios of urine, bile juice, liver, kidney, brain and blood were 15.7, 4.0, 1.2, 1.4, 1.4 and 1.0 respectively. There was a big difference in concentration of CSP and MPB in 7 cases due to differences in the amount of dose administered and time to death after dosing.

본 연구는 뉴욕 거버너스 아일랜드 프로젝트를 사례로 삼아 오랜 시간 동안 대중과 단절되어 있던 공간이 공원이나 공공 공간으로 조성될 경우, 참여 설계를 어떠한 방식과 단계로 진행하는 것이 적절한지 프로젝트 단계별로 심층 고찰한다. 그 결과, 단계적 참여 설계의 방식은 다음과 같이 분석되었다. 첫째, 프로젝트 준비 단계에서는 넓은 의미에서 참여 설계의 일환으로 공론의 형성이 있었다. 다양한 사람들이 원하는 방향으로 개발하기 위해 합의점을 찾는 시도가 여러 주체의 주도로 이루어졌다. 둘째, 프로젝트 착수 단계 이전에 대상지를 공공에게 개방하고 다양한 활동을 지속적으로 유치함으로써 지역에 대한 애착을 높이고 커뮤니티를 형성해 나갔다. 셋째, 공모전 이후 프로젝트 마스터플랜 완성 단계 전까지, 다년간의 커뮤니티 형성 단계를 거치며 만들어진 커뮤니티의 사회적 상호작용을 통해 실질적이고 적극적인 참여 설계가 이루어졌다. 넷째, 프로젝트 세부 설계와 조성 단계에서는 공청회와 같은 전통적이고 소극적인 방식의 참여 설계를 시행함으로써 전문적인 설계 내용 및 전문가의 영역을 보전하였다. 공공의 참여는 공원의 큰 틀을 만드는 마스터플랜 단계에서 대부분 반영되고 구체적인 설계에서는 그 내용을 전문가가 발전시킬 수 있도록 함으로써 일반 시민과 전문가가 각자의 역할에 충실히 하는 효율적이고 효과적인 결과를 낳았다. 본 연구의 결론은 다음과 같이 요약될 수 있다. 프로젝트 단계별로 참여 설계의 방식을 다르게 할 필요가 있다. 즉, 단계별로 공론의 형성, 커뮤니티의 형성과 발전, 커뮤니티의 사회적 상호작용을 위한 참여 설계가 구상되어야 하며, 참여하는 시민과 전문가 각각의 영역을 보전하는 것이 효과적이다. 특히 공론과 커뮤니티의 형성 단계를 참여 설계의 한 과정으로 확장하는 것이 중요하다. This study, which takes the New York Governors Island project as an example, is an in-depth analysis of the process of participatory design for transforming a space that had long been isolated from the public into a park and/or communal space. We found that the process of participatory design at each project phase consists of the following. First, in the preparatory phase, there was construction of public discourse: efforts to find a consensus to develop the space in a public-driven direction was led by various initiatives. Second, by opening the site to the public before the design phase and by consistently inviting a wide range of activities, a community was formed and its attachment to the site was established. Third, after the competition until the completion of the project master planning phase, substantial and active participatory design was enabled through social interaction of the community formed and developed over many years. Fourth, in the detail design and implementation phase, a traditional and passive way of participatory design such as public hearings was used, thereby preserving the expertise of professional designers. Public participation was reflected most in the master planning phase to create a broad framework of the park, while professionals designed the more specific aspects; this efficient and effective approach enabled both citizens and professionals to dutifully take part in developing the park. The results of this study can be summarized as follows. The mode of participatory design should be varied at each project phase, from construction of public discourse, to formation and development of the community, to participatory design for social interaction. Furthermore, it is effective to preserve the unique roles of citizens and design professionals. It is particularly important to extend the process of participatory design to include the construction of public discourse and community.

Even though driving under the influence of drug (DUID) is a worldwide problem, we, Korea has no regulation system yet except for alcohol, and there are little cases reported related to DUID. In order to investigate the type of abused drugs for drivers in Korea, we tried to analyze controlled and non-controlled drugs in alcohol-positive blood samples. 275 whole bloods, which were positive for alcohol on the roadside test, were collected from the police for two months ($Nov.{\sim}Dec.$ 2006). The analytical strategy was constituted of three steps: First, alcohol in blood samples were confirmed and quantified by gas chromatography. Second, controlled drugs were screened by $Evidence_{investigator}\;^{TM}$ (Randox, U.K.) as preliminary test. It was based on immunoassay by biochip array analyzer. Nine groups of drug abuse were screened: amphetamines, methamphetamines, cannabis, cocaine, opiates, barbiturates, methadone, benzodiazepines I (oxazepam) & II (lorazepam). Finally, confirmation of these drugs was performed by GC-MS. Blood samples were extracted by solid-phase extraction by $RapidTrace^{TM}$ (Zymark, U.S.A.). After trimethylsilyl (TMS) derivatization, eluates were analyzed to GC-MS. Total 49 drugs were investigated in this study including controlled drugs, antidepressants, 1st generation antihistamines, dextromethorphan, nalbuphine, ketamine, etc. For rapid detection, we developed the automated identification system. It was made up a new software, "DrugMan", modified Chemstation data analysis menu and newly developed macro modules. A series of peak selection, identification and reporting of the results were performed automatically by this system. Concentrations of alcohol in 275 blood samples were ranged from 0.011 to 0.249% (average, 0.119%). Among 149 blood samples, just six samples (4.0%) were showed positive results to the immunoassay: one methamphetamine and five benzodiazepines group I. By GC-MS confirmation, only benzodiazepines were detected and methamphetamine was not detected from immunoassay positive blood sample. Besides these drugs, 5 chlorpheniramines, dextromethorphan, diazepam, doxylamine, ibuprofen, lidocaine and topiramate were also detected in whole bloods by GC-MS. Conclusively, the frequency of drug abuse for Korean drivers was relatively low. There was none case which illegal drug was detected. However these results were limited to alcohol positive blood samples, so it is necessary to analyze more samples including alcohol negative blood.

This paper includes a review of 555 drug-facilitated sexual assault (DFSA) cases analyzed at the National Forensic Service (NFS), South Korea, between 2006 and 2012. The results of toxicological analyses of blood and urine samples were also reported, and furthermore the results were interpreted with respect to the number of drugs detected. The number of DFSA cases was highest during warmer summer months and the mean age of the victims was 25 years, with 48% being between 20 and 29 years. Accommodations or entertainment places were the most frequent place of the sexual assault (57%); and the assailant was a stranger in 72% of the DFSA cases. Drugs were identified in the blood or urine samples in 145 cases (26%) and sedative-hypnotics, such as benzodiazepines and zolpidem, were the most commonly detected, along with sedative antihistamines such as doxylamine and diphenhydramine. The frequent presence of sedative drugs in biological samples tends to implicate their use in chemical submission. However, interpreting the analytical results in terms of voluntary vs. surreptitious administration of drugs requires further detailed investigation and knowledge of the victim's health status and medication used at the time of event.

Objective: This study purposed to provide implications in regards to the Moon Jae-in Administration that launched in May 2017. Three sectors of childcare polices on administration of childcare centers were reviewed in terms of supporting the healthy development of young children. Methods: Medium and long-term childcare plans and the main policies of previous administrations since 2004 when the Childcare Act was completely reformed, as well as the 'Five-year policy for the Moon Jae-in administration of state affairs' that was announced on July, 2017, were reviewed in terms of publicness of childcare, regulations on operation of childcare services, and customized childcare programs for diverse needs. Results: It was proposed that the concept of publicness of childcare should be conservative when focusing on public childcare centers. The regulations on operating childcare services should focus on improving structural dimensions of childcare quality to keep the well-being of children a top priority. Furthermore, diverse programs should be designed and implemented to satisfy changes in childcare surroundings and the various needs of children and their families. Conclusion/Implications: The Moon Jae-in administration is expected to outline childcare policies and carry out tasks under the new paradigm. The healthy development of young children should be embodied as the final goal that forms the vision of childcare policies based on publicness, rationality, and diversity.

Neurofascin, one of the members of L1CAM, has been known to have some important roles during the development of nerve fibers. In order to investigate the role of neurofascin associated with the formation of Schmidt-Lantermann incisure in the sciatic nerve, the localization of neurofascin was studied with electron microscopy, immuno-fluorescence and immuno-electron microscopy. In the electron microscopy, the first formation of Schmidt-Lantermann incisure was checked at postnatal day 6 and the complete form of incisures traversing the whole myelin sheath began to be observed at postnatal day 8. In the immunofluorescence, neurofascin immunoreactive Schmidt-Lantermann incisures were first checked at postnatal day 6 and dramatically increased with aging by postnatal day 56. In the immunoelectron microscopy, neurofascin immunoreactive gold particles at the incisure forming sites were first observed at postnatal day 6 and the number of gold particles was increased as the animal was getting old by postnatal day 56. According to the present study, neurofascin is likely to have some relationships with Schmidt-Lantermann incisure formation.

CDP/Tencel 혼방사의 혼합비와 섬도에 따른 물리적 특성의 변화

Blended yarns comprising CDP and Tencel (TA) were produced for fabrics with improved color intensity. Their tensile force and extension and bending properties were investigated to evaluate their ease of handling during use. Their surface properties were also assessed by SEM and evaluating hairiness. Tensile force and extension decreased with increasing TA content due to slippage between CDP and TA. Bending strength was directly proportional to TA content.

Hansan ramie fibers were irradiated with an electron beam to improve the interfacial bonding in the manufacture of composites. The effect of electron beam irradiation was examined by SEM, chemical component analysis and the mechanical properties. The impurities on the surface of ramie and lignin were removed by electron beam irradiation, which increased the tensile strength of the ramie fibers. However, the excessive electron beam energy caused the degradation of ramie fibers, due probably to the reduced ${\alpha}$-cellulose. The reduction of ${\alpha}$-cellulose indicates the degradation of the cellulose chain, which usually leads to a decrease in fiber strength.
