The purpose of this study carried out to analyze production status, pricing trend and distribution status of landscape plants, so that it could predict the demand of landscape plants for the balance of supply and demand. The production amount of landscape plants made constantly increased. The annual output of shrubs increased more higher than that of trees. The prices of trees have raised consistently, but shrubs were susceptible to price fluctuations. And there were still many problems in the distribution structure. The landscaping work has focused on the metropolitan area. And large-scale nationwide projects were scheduled for coming years, so the demand of landscape plants was expected to expend. However, the lack of increase in production amounts of landscape plants, it is cause to supply problems. So, demand forecast was necessary to control the production of landscape plants.

In apparel industry, the production of clothing for the global market, has it#s origin in its characteristics depending on hands on working style, according to the globalization of a fashion industry. These days, however, the globalized production is unable to keep pace with the short cycle of production due to the unpredictable change of the taste or demands in the local area, as a result, the industry has come to take a focus on the production and consumption in the circumscribed region. In this stream, the northeastern area, specially, Dalian which is renowned for a center of fashion was designated as a city of this study as a representative. The cultural, racial and geographical uniqueness, asks for the analysis, based on the individual local area on the part of Korean fashion company desiring to launch into China fashion market. The purpose of this thesis is to analyse the style, color, and items of street fashion in Dalian. I would contribute to the understanding the preference of fashion in northeastern area, thereby, affording a fundamental resources for designing strategies for Korean fashion brands in China. The period of investigation is about 5 weeks from 14 May 2006 until 18 June 2006, with combined use of camcorder and digital camera. The site was Victory Shopping Plaza, in center of city, also with Mycal, Ansung, Dasang department store situated in the Economic Development area. The result of this study are as follows: 1. Preferred clothing styles are casual styles(68%) rather than formal styles(32%). In the casual styles, sports casual(36.0%), character casual(29.5%), jean casual(2.6%) were listed. All kinds of clothes are tightly fitted due to the stretched fabric and knit fabric. 2. Preferred colors are white(31.1%), red(16.6%), black(15.8%) khaki(7.8%) and blue(7.6%) for tops, and black(34.6%), blue(27.2%), white(15.4%), brown(14.6%) for bottoms. 3. Preferred clothing items are T-shirt(36.5%), jumper(33.6%), jacket(20.0%), blouse(8.7%), etc.(1.2%) for tops, pants(91.4%), skirts(8.6%) for bottoms. In the pants, cigarette pants(34.6%), bell bottom pants(21.0%), cargo pants(19.9%), straight pants(15.9%) were listed respectively. In the skirts, flare skirt(3.9%), tight skirt(2.2%), semi tight skirt(1.7%), pleats skirt(0.8%) were listed.

In-situ production of PC (precast concrete) members can reduce costs by about 14.5% -21.6% compared to in-plant production due to the reduction of transportation costs, factory profits and overhead costs. However, in-situ production of PC members presents a variety of risks, including member production and yard area securing, and lead time for production within the installation period. To solve this, it is necessary be able to analyze and control and monitor the risk factors that influence in-situ production for PC member. The purpose of this study is to develop a dynamic simulation model for in-situ production and erection integrated management for PC members. For this study, risk factor identification, causal loop diagram, and dynamic simulation model construction were performed sequentially. The results of this study will be used as a basis for developing a risk management model for PC in-situ production.

고온수증기전기분해(HTSE) 장치의 수소생산 및 열 화학적 특성을 파악하고자 COMSOL $^Multiphysics^{(R)}$를 사용해 2차원 정상상태 수치해석을 실시하였다. 계산을 위한 주요 파라메터로는 작동전압, ASR(Area-specific Resistance) 및 유입가스의 온도와 압력 등이다. 해석결과 1.2454 V에서 Thermal-neutral Voltage가 나타나고, 작동 전압이 증가함에 따라 Cell의 내부 온도가 단조 증가하는 것이 아니라 Thermal-neutral Voltage를 기준으로 낮은 전압에서는 Cell의 온도가 감소하고, 높은 전압에서는 Cell의 온도가 증가하였다. 또한, ASR 값이 증가함에 따라 Cell 내부의 온도는 하강하고, 수소생산율도 낮아지는 경향을 보였다.

이 연구는 정부의 목재산업진흥 종합계획에 기초하여 장기적인 산림의 영급구조 변화와 국내재 공급 가능성에 대해 살펴보았다. 목재는 주벌과 수종갱신, 피해지 벌채, 솎아베기 등을 통하여서만 공급된다고 가정하였다. 영급별 면적의 동태적인 변화를 추정하기 위하여 코호트 관계식을 이용하였다. 2010년 전체 시업지의 7.7%에 불과하던 6영급 면적이 크게 증가하여 2100년에는 약 73% 정도를 차지할 것으로 분석되었다. 반면 다른 영급의 면적은 5.3~5.6%의 분포를 나타낼 것으로 전망된다. 목재공급에 있어서는 주벌에 의한 생산이 93~95%를 차지할 것으로 예상된다. 2영급과 3영급의 면적에 좌우되는 솎아베기 생산량은 면적의 감소와 함께 점진적으로 줄어들 것으로 예상된다. 국내재 예상 공급을 선행연구 결과로 제시된 국내재 예상 수요와 비교하여 자급률을 계산한 결과 2050년에 83% 정도 될 것으로 예상된다.

The present study analysed the various productive and reproductive characteristics of 1/2 Pabna Milking Cows (PMC)-1/2 Sahiwal (S) and 1/4 PMC-3/4 S collected from the Pabna milkshed area at Baghabarighat, Sirajgonj, Bangladesh. The studied traits were birth weight (BWT), age at puberty (AP), number of services per conception (NSC), post partum heat period (PPHP), gestation period (GP), daily milk yield (DMY), lactational production (LP), lactation length (LL), fat percentage and solids-not-fat percentage (SNFP). Five individual Sahiwal sires were used for the upgrading of Pabna Milking Cows. The used data covered from 1987 to 1994. Least-squares analysis of variance showed that genetic group had a significant effect on BWT (P < 0.05), AP (p < 0.01), DMY (p < 0.01), LP (p < 0.001), LL (p < 0.05), FP (p < 0.05) and SNFP (p < 0.01). Genetic group had non-significant effect on NSC, GP and PPHP. The effect of sire was significant on BWT (p < 0.01), NSC (p < 0.01), LP (p < 0.05) and LL (p < 0.05). The AP, NSC, DMY, LP, LL and SNFP were higher in 1/2 PMC-1/2S cows; BWT and PPHP were higher in 1/4 PMC-3/4S but GP and FP were almost same in both genetic groups. From this study it may be concluded that production and use of 1/2 PMC-1/2S would seem more profitable for commercial milk production in the Bangladesh Milk Producers' Cooperative Union Limited (BMPCUL) area and at the same time emphasis should be given on rigorous sire selection.

This paper describes a research work of developing a computer-aided design of irregularly shaped-sheet metal product with bending and piercing operation for progressive working. An approach to the CAD system is based on the knowledge-based rules. Knowledge for the CAD system is formulated from plasticity theories, experimental results and the empirical knowledge of field experts. The system has been written in AutoLISP on the AutoCAD with a personal computer and is composed of five main modules, which are input and shape treatment, flat pattern-layout, production feasibility check, blank-layout, and strip-layout module. Based on knowledge-based rules, the system is designed by considering several factors, such as radius and angle of bend, material and thickness of product, complexities of blank geometry and punch profile, and availability of press. This system is capable of unfolding a formed sheet metal part to give flat pattern and automatically account for the adjustment of bend allowances to match tooling requirements by checking dimensions and the best utilization ratio of blank-layout within bending production feasibility area which is beyond ${\pm}30^{\circ}$ degrees intersecting angle between grain flow and bending edge line and which is suitable to progressive bending operation. Also the strip-layout drawing generated by a bending and a piercing operation according to punch profiles divided into automatically for external area of irregularly shaped-sheet metal product is displayed in graphic forms.

국내 최초로 5세기 대 옹관을 생산하는 가마가 나주시 오량동유적에서 발견되었다. 이 가마는 영산강 중류에 입지하고 있으며 고대사회 장묘연구에 있어서 생산과 유통구조 그리고 소비체계를 연구할 수 있는 귀중한 자료이다. 따라서 이 가마에서 생산되는 옹관이 어디로 소비되었는지를 밝히기 위하여 인근 영산강유역을 중심으로 하는 대표적인 옹관 고분유적 5기와 4세기 대 만동유적에서 발굴된 옹관유물을 대상으로 하였다. 중성자 방사화분석법을 이용하여 각 유물들의 미량성분을 분석하고 그 결과를 판별분석을 이용한 통계분석으로 산지의 동일성을 추정하였다. 나주 오량동 가마에서 생산된 옹관은 교역과 유통을 통하여 나주 반남고분, 영암 옥야리고분, 그리고 함평 반암고분에서 사용되었을 가능성이 크다. 또한 고창 만동유적과 무안 인평고분의 옹관은 나주 오량동 가마에서 생산된 것이 아니라 다른 산지의 옹관 가마로부터 교역과 유통을 통해 유입되었다고 사료된다.

본 연구에서는 국내 시설원예 부문의 발전을 주도하고 있는 과채류 가운데 참외 농업을 중심으로 농업의 산업화 과정에서 나타나는 지역적 전문화를 규명하고자 했다. 참외는 장기간에 걸쳐 시설 재배가 진전된 작목으로서 생산의 집약화와 공간적 집중화가 진행되는 과정에서 일부 지역을 중심으로 전문화가 심화되고 있기 때문이다. 이러한 논의는 국내 최대의 참외 주산지로 성장한 경상북도 성주군 일대를 중심으로 수행되었다. 구체적인 연구 목적은 첫째, 국내 참외 농업의 집약화와 공간적 집중화를 개관하고 둘째, 성주군 참외 농업의 전문화를 토지이용, 재배 시설 및 관련 기술, 노동의 분업 측면에서 고찰하는 것이다. 이를 위해 관련 통계자료를 구득하고 사례 지역의 주요 행위자들에 대한 심층면담을 실시했다.
