Purpose: In this study, pollutants generated in industrial areas were measured using a Portable Air Quality Measurement System(PAQMS). This study intends to examine in detail improvement measures and operational capabilities to operate a more efficient PAQMS. Research design, data and methodology: This study compares and analyzes the measurement values of the PAQMS and the measurement values of the national air quality measurement network. It is intended to develop a PAQMS corresponding to the data of the national measurement network by minimizing the errors that occur during comparative measurement and analysis and supplementing and improving the problems that occur during the current equipment calibration. Results: A PAQMS is an essential equipment for faster and more accurate measurement and analysis of pollutants in case of untimely measurement and civil complaints due to Micro Climate(local weather and environmental influences). Currently, there are many atmospheric measurement equipment in Korea, but only equipment for each item is produced and sold. Currently, these devices on the market must satisfy various conditions such as stable power, temperature, and humidity to calculate accurate measurement values. Conclusions: Therefore, there is no equipment that satisfies the conditions for performing detailed measurement in the field where accurate measurement is required. In this study, these field work conditions and contents for stable measurement were mentioned in the text.

Objectives : We performed a pilot study to investigate inter- and intra-rater reliability of pattern identification using nasal endoscopy for allergic rhinitis(AR). Methods : Eight experts of ophthalmology, otolaryngology and dermatology of Korean medicine evaluated 20 nasal endoscopy photograph cases of AR patients with pattern identification index using nasal endoscopy for AR including the nasal membrane color(pale / hyperemia), nasal membrane humidity(dryness / dampness), rhinorrhea(watery / yellow), and membrane edema (atrophic / edematous) on nasal endoscopy. Results : Intra-rater agreement(%) and Kappa coefficient was generally from 'moderate' to 'good'(% agreement: 73.13-90% / Kappa coefficient: 0.547-0.748). Inter-rater agreement(%) and Kappa coefficient was also from 'moderate' to 'good' (% agreement: 65-85% / Kappa: 0.475-0.778) except 'humidity(dryness / dampness)' item (% agreement: 55.98% / Kappa: 0.340). In findings of subgroup analysis according to affiliation of raters, Inter-rater agreement(%) and Kappa coefficient of raters in same affiliation was higher than inter-rater agreement(%) and Kappa coefficient of raters in different affiliation except 'dryness / dampness' item. Conclusions : It is necessary to improve objectivity and reproducibility of pattern identification using nasal endoscopy for allergic rhinitis(AR) through the development of detail-oriented criteria and enhanced training of clinicians with development of standard operating procedures(SOPs).

This research is focused on not only cultivated land as an important factor which represented the agricultural district, but also details of the research in the landscape of cultivated land. Moreover, we also focused on the cultivated land operating environmental friendly agriculture which took a lot of interest among the landscape of the cultivated land. The reason is, we judged environmental friendly agriculture is not only the simple purpose only for manufacturing food but also the key role for preserving their environment and landscape, and making sustainable agriculture. For this reason, our research treats the analysis that operating environmental friendly landscape has what kinds of different factors in landscape characteristic compare with other general agricultural methods. Plus we selected evaluating both the degree of citizen's presence and the degree of rural residents's importance in those factors as a mainly research matter. We drew out the landscape of cultivated land and concerning factors by analyzing policies(ESA, CSS, CTE, MFSP, ACL, etc) concerned with overseas agricultural landscape to deduct landscape Character factors in internal cultivated land. Based on eleven items of landscape factors in cultivated land deducted by documents research, we started to conduct field studies during MAY. 7th. 2004 $\sim$ JUL. 8th, DEC. 1th $\sim$ 3th reaching 32 villages and concerned institutes to deduct the factors in landscape characteristic in agricultural cultivated land in detail. We analyzed degrees of importance and preference in citizen and rural residents classified by 5 province of the whole country to evaluate the landscape Character factors in environmental friendly agriculture deducted by field research and 21 documents including extra items such as a scene of duck grazing by the duck techniques which is very popular way among internal environmental friendly agriculture, gardening space composed around farm and furrow on slope ground formed by unique topology in hilly country. The research period was progressed for 20 days from MAY. 28th. 2005 $\sim$ JUN. 17th. This research is the result that cultivated land landscape as a detail item holding agricultural environment especially, it is also meaningful result in environmental friendly agriculture as a basic research, because it is not only a value of simple food producing but also very effective role in both landscape and environmental parts.

Category of rare plant was reevaluated and evaluation technique for the grading of rareness in plant was developed. The results obtained from this study were as follows: 1. The evaluation technique of rareness in plant was not reflected in the current preparation provision for EIS. And t his fact also appeared in most of the EIS which were reexamined in this study. 2. The category of rare species which have been considered as the subject of protection in EIA have to be enlarged to more than legally protected species designated by MOE. 3. The taxonomic characteristics and status of species, characteristics of population, geographical characters, extent of threat and its possibility by man resulted from the habitat loss were investigated. Each item was endowed scores from 1 to 5 and all the scores were summed, and then this value was used to evaluate the order of conservation. 4. Conservation measures for the rare plants have to be applied according to the levels of rareness grade, and they are absolute conservation, in situ conservation, transplanting and ex situ conservation, post observation and none by the levels from A to E. 5. Considering the phenology of rare plants, investigation for the rare plants have to be made a1 least three times. 6. Size of the MVP(Minimum Viable Population), pollination ecology also have to be considered for the conservation of rare plants. And in the case of adopting ex situ conservation measure, the site and methods for the conservation of rare plants have to be proposed in detail.

The men's costume of eighteenth century showed feminine image of elegant decoration through the influence of social feminine atmosphere. As years go, heading towards the end of the eighteenth century, most of men's wear were simplified except vest, which had gorgeous decorations showing feminity. Therefore, men's vest of eighteenth was regarded as good item to apply to modern women's wear. The men's vest design of eighteenth century were divided into three types due to the passage of time, they showed the difference in the length, detail and trimming. Cutting lines in the modern fashion are used to give comfort and show the three-dimensional body silhouette. Also, cutting lines, as a decoration element, can define the costume's image and characteristics. Therefore, by using cutting lines, we can represent historical costume as modern costume and men's wear as women's wear. I made five women's costumes applying design characteristics of the men's vest of the eighteenth century. These five women's costumes have decorative aspect of men's vest of eighteenth century and simple aspect of men's costume. I applied dart manipulation in several different ways to make various cutting lines for women's costume. These cutting lines were emphasized by matching various colors and patterns of fabrics. I made small buttons and cords of these various fabrics. I sewed fabric buttons on five costumes for the purpose of function and decoration like buttons of the men's vest of eighteenth century. I applied fabric cords to decorate five costumes in various way. We should further study how to express important characteristics of historical costumes as modern costume in many ways.

최근 건설공사에 있어서의 VALUE ENGINEERING 적용에 대한 관심이 높아지고 있으며 VE WORK-SHOP 을 통한 많은 효과가 현대건설의 사례에서 입증이 되고 있음에도 신문매체 등에 발표되는 VE 관련 논고가 일반론적 기고에 국한되어 있어 VE에 대한 이해에 큰 도움은 되지만 갈증을 해소하기에는 어려운 실정이며 우리사회에 전문성을 가진 리더군이 많지 않음을 반증하는 것도 되기에 향후 좀더 많은 VE 경험을 토대로 한 리더군이 형성되어 다양한 주제를 기사화한 실무적인 VE 기법의 소개가 필요하다고 본다. VE 적용은 그 기법이 매우 다양하므로 해당 공사의 시기와 특성, 제약요소 팀원 구성의 전문성 등 다양한 요소를 종합적으로 고려하여 가장 적합한 형태의 VE가 추진될 수 있도록 VE 계획 시 추진 팀의 방향설정과 역할분담이 필요하고 준비되어야 한다. 특히 WORK-SHOP 형태의 VE는 현장 테마 중임의 ITEM VE에 비하여 적은 투입으로 많은 효과를 거둘 수 있지만 팀원의 전문성이 결여시 VE 작업결과의 시행에 따른 신뢰도가 떨어질 수 있는 가능성을 내포하고 있으므로 추진팀의 입장에서는 보다 세심하고 조직적으로 접근 할 필요가 있다. 성공적인 VE 작업을 하기 위하여서는 특히 WORK-SHOP 개념의 새로운 기법을 설계 및 시공초기에 단계적으로 적용하고 VE 팀 리더의 효과적인 VE 작업을 위한 절차의 명확한 이해와 선진 기법의 이해를 바탕으로 한 팀원의 교육과 가이드가 점점 중요한 요소가 되고 있다. 실제 건설공사에 있어 효과적인 VE를 적용하기 위한 핵심요소를 VE 교육을 진행하고 있는 담당 실무자 입장에서 정리하여 보았으며 기회가 허락되면 한 두 차례의 추가 연재를 통하여 상세히 논하고자 한다.

Objectives: To evaluate the methodological quality of Korean Acupuncture Clinical trials Methods : Two independent researchers reviewed 12 protocols of Acupuncture clinical trials which were conducted in Korea 2006. Also, Survey Principal Investigator of those was conducted. We compare the results of protocol review with investigator reponses of actual practice. Quality assessment consisted of 5 items including random sequence generation, randomization method, allocation concealment, subject blinding, assessor blinding. Results : Randomization was performed using the proper procedure to insure that treatment assignment is unbiased and concealed from subjects in all clinical trials, According to protocols, 6(50%) of 12 clinical trials used computer-generated random numbers, 6(50%) remaining trials didn't describe the randomization method. Also all trials used appropriate randomization methods on the basis of the survey results: 8 trials used computer-generated random number, 2 used random table. Of 7 protocols in which allocation concealment was stated, 5(71%) reported appropriate method (Calling a central office or statisticians, Sealed opaque envelopes). However according to survey, 5(42%) of 12 trials used inappropriate allocation concealment (Keeping a master randomization list and referring to when subject entered the trial). In addition, the result of protocol review and survey response was not coincident in 5(42%) trials. Subject blinding was conducted in all except 1 clinical trials. Although 11(92%) of 12 trials were conducted using assessor blinding in actual practice, only 7(58%) reported that in protocol. Conclusion : Although randomization and blinding were conducted adequately, allocation concealment was used inadequately, Not only appropriate allocation concealment, but also every quality assessment item including randomization, blinding should be stated in more detail in protocol.
