This study examined the impact of community facilities on parents` perceptions of visiting public libraries. Previous research on public libraries has focused on the services provided by libraries, including the provision of information and the space for holding programs in the buildings. Urban planners have also insisted that the interaction between primary and convenience functions makes libraries work best. However, previous research has paid little attention to the connection between libraries and community facilities. We investigated whether the proximity of parks and transportation services has an impact on parents` perceptions on visiting libraries with their children. A field survey was conducted at 8 public libraries in Busan Metropolitan City, and the data from 488 respondents were analyzed with the ordered logit model. The results revealed that parents were more likely to visit public libraries near parks. Therefore, librarians, policymakers, and urban planners should consider the location and function of public libraries in relation to community facilities/services during the urban planning and design process to encourage the use of public libraries by parents and their children.

This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

목적 : 골 연장술 후 생기는 연장 가골에 황화 칼슘과 이종 이식골을 투여하여 골 경화 속도에 대한 영향을 알아보기 위한 실험이었다. 연구대상 및 방법 : 성장중인 뉴질랜드 화이트 토끼(2.0-2.5㎏)의 경골 간부에 골막을 보호하고, 절골술을 시행하고, 5일간의 휴지기후 외고정 장치를 이용하여 1주일 동안 7㎜가 연장될 때까지 하루 1㎜씩 2회의 리듬을 가지고 골 연장을 실시하였다. 제1 실험 군 7마리에는 연장이 끝난 직후 황화 칼슘(Osteoset^(ⓡ), Wright medical USA) 1정, 제 2 실험 군 7마리에는 이종 이식골의 일종인 Lubboc 5㎟을 각각 연장된 가골 부에 주입하고, 단순 연장한 대조군 7마리와 함께, 방사선 및 골 밀도비를 측정하고 추시하여, 골 경화의 진행속도를 비교하였다. 방사선 촬영은 전후면 및 측면사진을 1주 간격으로 촬영하였고, 골밀도 측정은 DEXA(dual energy X-ray absorptionmetry, Lunar^(ⓡ)) 장치를 2주일 간격으로 시행하였다. 결과 : 방사선 소견상, 제 1실험군의 연장가골의 완전 경화시간은 평균 14주, 제 2실험군은 154 주로 각각 대조군의 16.9주보다 단축되었으며, 골 밀도 비에서도, 두 실험군에서 최고치가 대조군의 값보다 높고, 최고치까지의 경과기간도 빨랐다. 결론 : 본 연구에서 연장 가골에 황화칼슘 및 이종 이식골의 투여가 골 경화의 기간을 단축시킬 수 있고, 외고정 장치의 빠른 제거에 도움이 될 수 있음을 알았다. Purpose : This study was designed to know the effect of calcium-sulfate and xenograft on the distracted callus after lengthening. Materials & Methods : We had operation of subperiosteal osteotomy and external fixation on the tibial diaphysis of young New Zealand White rabbits(2.0-2.5㎏); after 5 days of latency period, 7㎜(1㎜/day, 2times/day) of tibial lengthening was reached in a week. At 1 week after lengthening, the 1st experimental group of 7 rabbits received a pellet of calcium sulfate(Osteoset, Wright medical, USA) in the distraction gap, and the 2nd experimental group of 7 rabbits received 5㎜ 2 of xenogrfat(Lubboc) in the distraction gap. But, the control group of 7 rabbits did not receive any of above materials. We compared three groups with the changes of radiographic findings at every week and bone mineral ratio(DEXA) at every two weeks. Results : The time to complete consolidation of distraction callus of both experimental group(calcium sulfate;14 weeks, xenograft; 15.4 weeks) was shorter than that of control group(16.9 weeks) in radiographic findings. Maximum value of bone mineral ratio of distraction callus was higher and the time to reach the highest value was also shortened in the both experimental group compared to control group. Conclusion : By use of bone substitutes as like calcium sulfate or xenograft in the distraction callus with external fixator, it may be possible to shorten the consolidation period and the fixator-wearing period.

박형철,김희수 홍익대학교 산업디자인 연구소 2004 미술디자인 논문집 Vol.- No.9

Furniture has an important role of storage in a residential space from the past. In particular, the cultural change, from the Joseon's sitting style to the modern standing style, resulted in various kinds of storage furniture. This phenomenon has been accelerated to the present. Besides some exceptions, most of the wooden furniture from the Joseon dynasty is rarely found in our daily living space because the furniture is not well preserved as a result of the changes of residential environmentand the user's taste. In addition, the study resources about wooden furniture do not well remain either: the inheritance of the making process and the background of producing wooden furniture. This study is about cabinets, which is one of the most necessary furniture for living in the Joseon dynasty. The study had to limit the studying objects because there is wide variety of the wooden furniture and small number of them remained. As the research method written records were investigated at first then field researchwas done an actualextant cabinets to identify the background and the usage of each parts. Through the field research oral records, photos, actual measurements, and written information from inscriptions were collected and studied. This method was considered the most reasonable way for the reliability of information and for the convenience of comparative analysis in the given condition. Through the research two problematic situation were pointed out: first, the shared information about the traditional wooden furniture is mostly from the 19 th century in the Tate Joseon dynasty but it is regarded as a representative one of the whole period of the dynasty; secondly there is not clear standard or reference for the name and usage of the detail parts of the traditional wooden furniture. The present classifications vary depending an the results of the previous researches. The research results in collecting valuable information to study further in comparison with other previous researches; maker, time, name of each part, and written records about the producing process. The meaning of this study is to collect the fundamental information from the written records and field research, which would enable more comprehensive study about traditional wooden furniture of the 19th century. Furthermore this study may contribute to appreciate the value of Korean aesthetics in Korean furniture as well as in traditional wooden furniture.

저자들은 만성골수성백혈병으로 동종 골수이식 후 림프구성급성전환으로 재발한 환자에서, Gleevec 투약 후 DLI (donor lymphocyte infusion) 없이 공여자 조혈(donor hematopoiesis)의 재건이 이루어지고, 세포유전학적, 분자생물학적 기준에서 모두 완전관해에 이르고, 12개월째 관해를 유지하고 있는 환자를 경험하였기에 이를 보고하는 바이다. 본례의 환자에서 Gleevec은 동종 골수이식 후 급성전환기로 재발한 환자에서도 매우 효과적인 것으로 나타났다. Gleevec은 동종 골수이식 후 재발한 만성골수성백혈병에서 Interferon-α, DLI, 2차골수이식 등 기존의 치료의 문제점을 보완할 수 있는 유용한 치료방법으로 사용될 수 있을 것으로 생각되며, 이의 장기적 치료효과의 평가와 기존치료와의 병합요법의 유용성 등에 대한 향후 연구가 필요할 것으로 생각된다. We report a 32-year old woman with chronic myelongenous leukemia (CML) in lymphoid blast crisis, who underwent allogenic bone marrow transplantation (BMT) from HLA phenotype full mached unrelated donor. Her disease relapsed into full-blown blast crisis. Upon treatment with gleevec, she achieved immediate remission of leukemia as well as the donor type hematopoiesis without donor lymphocyte infusion (DLI). Our case suggests the high effectiveness of gleevec in CML relapsed after allogeneic BMT. Further studies are needed to define the role of gleevec (with or without DLI) in the management of CML relapsed after allogeneic BMT.

Toluene diisocyanate(TDI) has been known the materials which is induced occupational asthma, is mostly used by the materials of industrial polyurethane, excreted as toluene diamine(TDA) in case of occurring metabolism in the human body when it inhaled. This research is demonstrated to make scrutiny into efficiency of two differentways of sampling in comparison with the cocentration after make use of the open cassette holder and the modified 2-piece cassette holder which are originaly existing to doing sampling 2,4-TDI as 2,6 TDI in the air, and to present more adequate way to TDI sampling in the air and to present more adequate way to TDI sampling in the air from comparing concentration TDA in a worker's urine with concentration of TDI which is being sampling each ways And this study want to grasp the influence for TDA excretion by exposing TDI from the general character of workers. The study was experimented on the 22 workers from the factory where is pperated paining work using by paints from poly urethane. This study was performed to identify the personal character of workers by using the questionnaire. analysed TDI from 44 sample each in the middle of morning and afternoon and TDA from the 17 workers by take their urine. Open cassette holder is manufactured to face the filter with the outside by remove the modified 2-piece cassette holder eliminated he middle of section and top of the upper holder. As a result of analysis, the concentration of TDI in the air is higher on the mokigied 2-piece cassette holder than the open cassette holder for sampling, There was no different on the concentration of urinary TDA by personal character. The concentration of TDI in the air had a relation with the concentration of urinary TDA no matter what kind of sampling method used, but the sampling by modified 2-piece cassette holder had more relation than sampling by open face cassette holder. As a result of this experiment, the concentration of TDI by sampling from the each cassette holder has shown to us significant relation with the concentration of urinary TDA.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.
