The meaning and role of public space has existed based on the periodical situation like history. The more the time has passed, the faster the meaning of it has changed. We can see the differences of it from the one which used to be. This study is about Platoon Kunsthalle which is so-called the complex cultural space. The purpose of this study is to show how the user is related to the program for the planning of the public space. It is based on the procedure of the research with absorbing the place. The people who are using the space are absorbed for knowing the user's action. And then, the specific actions are written and the status of the using space is photographed. The research is based on asking and answering about that. The result of this study is as follows : The first is that young people between 20's and 30's are using a hall comparing with other age through daily using of space and features of users. Also, Using between 7p.m. and 9p.m., a dinnertime, takes the first place and using of meals and beverages is major at lunch due to restaurant and bar. User behavior of "sitting" is the biggest part and the hall is used for the public purpose connected with "talking". The second is that the daily hall space is classified with the spacial area indirectly based on the condition. Also, it depends on the time and the using. The third is that the unusual hall space is depended on the program which is the role of leading the extention of using the space. That is why the program is important because it is effected directly to the way of using the space and the place of the furniture. I am looking forward that this study is the basic data for the planning of the public space in the complicated culture.

Background: The Global Adult Tobacco Survey has 15 key indicators, cigarettes smoked per day (CPD) among daily smokers being one of them. The first wave of GATS in 14 countries indicated that mean CPD use is higher in women than men in India only, which is contrary to the current understanding of tobacco use globally. This study was undertaken to understand the unusual findings for mean CPD use in the GATS-India survey. Materials and Methods: Items B06a and B06b of the GATS India survey questionnaire that collected information on daily consumption of manufactured and rolled cigarettes were analyzed using SPSS software. Exclusive users were identified from these items after excluding the concurrent users of other tobacco products. Cigarette type, exclusive use and gender stratified analyses were made. Consumption of different types of cigarettes among the mixed users of manufactured and rolled cigarettes were correlated. Results: Higher mean number of CPD use among male daily-smokers was observed than their female counterparts in product specific analysis. Mean CPD as per GATS cigarette definition was higher in males than females for exclusive users but a reverse trend was observed in case of non-exclusive users. Use of manufactured cigarettes increased with increase in use of rolled cigarette among the mixed users and around half of these users reported equal CPD frequency for the both types of cigarettes. Conclusions: The anomaly in mean CPD estimate in GATS-India data was due to inclusion of two heterogeneous products to define cigarettes, variation in cigarette product specific user proportions contributing to the average and non-exclusive concurrent use of other tobacco products. The consumption pattern of cigarettes among the mixed users highlights bias in CPD reporting. Definition, analysis and interpretation of 'cigarettes per day' in the GATS India survey need to be improved by redefining cigarettes and making product specific analyses.

The mucoepidermoid carcinoma is classified as either well, moderately, or poorly differentiated. The criteria used to classify the lesions are discussed, and pathologic features are illustrated. The most important factors in prognosis are : 1. degree of histologic differentiation, and 2. presence or abscence of tumor on the lines of surgical excision. Recurrences rates are correlated with histologic differentiation. Stewart, Foote, and Becker in 1945 coined the term "mucoepidermoid tumor" to discribe an unusual salivary neoplasm containing epidermoid and mucus-secreting cells which was thought to arise in salivsary gland ducts. The treatment of the mucoepidermoid carcinoma is chiefly surgical, although recent data have shown favorable responses to radiation therapy. Currently, surgery followed by radiation treatment is recommended for intermediate-grade and high-grade tumors ; low-grade tumors can be managed by surgery alone. Authors present a case of mucoepidermoid carcinoma managed with wide surgical resection and postoperative irradiation and showing a good clinical result with review of literatures.

Cyanobacteria have been widely reported to produce a variety of UV-absorbing mycosporine-like amino acids (MAAs). Herein, we reported production of the unusual MAA, mycosporine-glycine-alanine (MGA) in the cyanobacterium Sphaerospermopsis torques-reginae ITEP-024 using a newly developed UHPLC-DAD-MS/HRMS (ultra-high performance liquid chromatography-diode array detection-high resolution tandem mass spectrometry) method. MGA had previously been first identified in a red-algae, but S. torques-reginae strain ITEP-024 is the first cyanobacteria to be reported as an MGA producer. Herein, the chemical structure of MGA is fully elucidated from one-dimensional / two-dimensional nuclear magnetic resonance and HRMS data analyses. MAAs are unusually produced constitutively in S. torques-reginae ITEP-024, and this production was further enhanced following UV-irradiance. It has been proposed that MAA biosynthesis proceeds in cyanobacteria from the pentose phosphate pathway intermediate sedoheptulose 7-phosphate. Annotation of a gene cluster encoded in the genome sequence of S. torques-reginae ITEP-024 supports these gene products could catalyse the biosynthesis of MAAs. However, addition of glyphosate to cultures of S. torques-reginae ITEP-024 abolished constitutive and ultra-violet radiation induced production of MGA, shinorine and porphyra-334. This finding supports involvement of the shikimic acid pathway in the biosynthesis of MAAs by this species.

Human beings are having suffered from the unexpected climate changes which are caused by global warming leaded from air pollution. More than 3 billions of people will be forced to experience insufficient water in 2015. In Korea, over 70% of precipitation has been concentrating in Summer season. Furthermore, natural disasters has been occurred constantly all over the country. The unusual flood and drought have broken out not only victims but also, property damages. By the natural condition, the effective consuming and controlling system of water is going to be the core business field and constructing dams will be encouraged and promoted for the system. To convince the objectionable against the constructing dams, a dam exhibition center stands the very important position by being responsible for the presenting positive factors and highlighting the beneficial functions. The dam exhibition center is built as complex space combined by information center regarding water resources and visitor center for the community nearby the inundated area. Combined of the different purposes, the dam exhibition center can be confused to understand the concept and contents established in the space. To enhance the visitors' understanding contents of the dam exhibition center, the spatial composition and contents are being analyzed with existing centers and define the most effective exhibition methods between the spaces and visitors. This study will be the basic quantitative analysis data for the following design works those can get the better insight how to make visitors to get information and agreement of constructing dams effectively.

본 논문에서는 파일이 요청된 순간에는 파일의 선호도만을 조사하고, 일정 시간이 흐른 후에 선호도가 높은 파일들을 일괄적으로 캐싱하는 새로운 캐싱 전략을 소개한다. 이 전략에서는 일정 기간 동안 캐시의 상태가 변하지 않기 때문에 캐시 조작 비용이 거의 들지 않는 매우 효과적인 자료 구조의 사용이 가능하다는 장점을 가지고 있다. 뿐만 아니라, 국내외 5개 웹 서버로부터 수집한 log 파일을 대상으로 실험한 결과에 의하면, LRU를 사용하였을 때보다 오히려 캐시 히트율이 증가하였으며, 캐시 내 자료 재사용율도 증가하는 장점을 보석 주고 있다. 본 논문에서 제안하는 선호도 기반 게으른 캐싱전략(Popularity Based Lazy Caching Strategy)은 캐시에 포함되지 못한 파일의 선호도가 크게 증가하는 경우에 성능이 떨어지는 단점을 가지고는 있다. 그러나 이러한 경우는 자주발생하지 않으며, 웹 서버를 적응적으로 구현하여 해결할 수 있다.

The current status of the curricula of departments related to Clothing & Textiles was checked. The names of colleges and departments affiliated with Clothing & Textiles were also examined. Data on introduction of curricula and subjects disclosed on the website of 60 universities were collected, and the total number of subjects collected was 2,306. As a result, the following conclusions were reached: First, departments related to Clothing & Textiles were the most frequently affiliated with the art/design schools. Depending on the name of the department, the colleges they belong to were different. It was found to be related to the name of the department and the name of the college. Second, According to a survey of the percentage of each major area in the curriculum, the portion of the fashion design area was the highest. The results of checking the composition ratio of the major areas according to the department name showed that there were differences in the curriculum according to the department name. Third, we looked for unusual subjects that were not found in other universities, which could be largely summarized into three: those for characterization, those for preparing for the Fourth Industrial Revolution, and those related to the current situation in the department of Clothing & Textiles. Fourth, we examined subjects related to the Fourth Industrial Revolution, and found that words such as 'sustainable', 'convergence', 'smart', 'knowledge property' and 'computer' were in common. However, the number of subjects was extremely low.

The complete mitochondrial genome of a troglobite millipede Antrokoreana gracilipes (Verhoeff, 1938) (Dipolopoda, Juliformia, Julida) was sequenced and characterized. The genome (14,747 bp) contains 37 genes (2 ribosomal RNA genes, 22 transfer RNA genes and 13 protein-encoding genes) and two large non-coding regions (225 bp and 31 bp), as previously reported for two diplopods, Narceus annularus (order Spirobolida) and Thyropygus sp. (order Spirostreptida). The A + T content of the genome is 62.1%, and four tRNAs ($tRNA^{Ser(AGN)}$, $tRNA^{Cys}$, $tRNA^{Ile}$ and $tRNA^{Met}$) have unusual and unstable secondary structures. Whereas Narceus and Thyropygus have identical gene arrangements, the $tRNA^{Thr}$ and $tRNA^{Trp}$ of Antrokoreana differ from them in their orientations and/or positions. This suggests that the Spirobolida and Spirostreptida are more closely related to each other than to the Dipolopoda. Three scenarios are proposed to account for the unique gene arrangement of Antrokoreana. The data also imply that the Duplication and Nonrandom Loss (DNL) model is applicable to the order Julida. Bayesian inference (BI) and maximum likelihood (ML) analyses using amino acid sequences deduced from the 12 mitochondrial protein-encoding genes (excluding ATP8) support the view that the three juliformian members are monophyletic (BI 100%; ML 100%), that Thyropygus (Spirostreptida) and Narceus (Spirobolida) are clustered together (BI 100%; ML 83%), and that Antrokoreana (Julida) is a sister of the two. However, due to conflict with previous reports using cladistic approaches based on morphological characteristics, further studies are needed to confirm the close relationship between Spirostreptida and Spirobolida.

Damages caused by torrential rain occur every year in Korea and summer time convection can cause strong thunderstorms to develop which bring dangerous weather such as torrential rain, gusts, and flash flooding. On 6 August 2013 a sudden torrential rain concentrated over the inland of Southern Korean Peninsula occurred. This was an event characterized as a mesoscale multicellular convection. The purpose of this study is to analyze the conditions of the multicellular convection and the synoptic and mesoscale nature of the system development. To this end, dynamical and thermodynamic analyses of surface and upper-level weather charts, satellite images, soundings, reanalysis data and WRF model simulations are performed. At the beginning stage there was a cool, dry air intrusion in the upper-level of the Korean Peninsula, and a warm humid air flow from the southwest in the lower-level creating atmospheric instability. This produced a single cell cumulonimbus cloud in the vicinity of Baengnyeongdo, and due to baroclinic instability, shear and cyclonic vorticity the cloud further developed into a multicellular convection. The cloud system moved southeast towards Seoul metropolitan area accompanied by lightning, heavy precipitation and strong wind gusts. In addition, atmospheric instability due to daytime insolation caused new convective cells to develop in the upstream part of the Sobaek Mountain which merged with existing multicellular convection creating a larger system. This case was unusual because the system was affected little by the upper-level jet stream which is typical in Korea. The development and propagation of the multicellular convection showed strong mesoscale characteristics and was not governed by large synoptic-scale dynamics. In particular, the system moved southeast crossing the Peninsula diagonally from northwest to southeast and did not follow the upper-level westerly pattern. The analysis result shows that the movement of the system can be determined by the vertical wind shear.
