  • 최근 고해상도의 격자형 기상자료를 활용한 기후변화 또는 농업기후분석이 시도되고 있다. 모형구동을 위해서는 각 격자별로 재배 정보를 입력해야만 한다. 이러한 입력정보 중 Oryza2000 에서는 육묘기간 온도상승값이 필요하며 이는 지역별로 파종기에 따라 변화될 수밖에 없다. 그러나 격자형 자료를 사용하여 모의할 때는 이것들을 모든 격자에 대해서 변화된 값을 주는 것은 어렵다. 이 문제를 해결하기 위해 철원, 수원, 서산, 광주에 대해서 4 월 중순부터 6 월 중순까지 육묘온도 상승값을 0℃, 2℃, 5℃, 7℃ 및 9℃로 적용하고 가장 변이 발생이 적은 온도를 선택하였다. 0℃와 2℃는 4 월 중순의 낮은 온도가 발생하였을 때 큰 변이를 보여 적절하지 않았으며 7℃이상에서는 변이가 줄어들었으나 모몸살 효과에 따른 출수지연 효과가 지역별로 파종기별로 과대평가되는 경우가 발생할 수도 있다. 따라서 전반적으로는 5℃가 가장 안정적인 출수날짜를 보였으며, 격자형 기상자료를 구동할 때는 이를 활용하는 것이 좋을 것으로 판단된다.

  • This study was carried out to examine the improvement plan by analyzing the characteristics of imported wastes, operation rate, and benefits of energy recovery for incineration facilities with a treatment capacity greater than 50 ton/day. The incineration facility capacity increased by 3,280 tons over 15 years, and the actual incineration rate increased to 2,783 ton/day. The operation rate dropped to 76% in 2010 and then rose again to 81% in 2016. The actual calorific value compared to the design calorific value increased by 33.8% from 94.6% in 2002 to 128.4% in 2016. The recovery efficiency decreased by 29% over 16 years from 110.7% to 81.7% in 2002. Recovery and sales of thermal energy from the incinerator (capacity 200 ton/day) dominated the operation cost, and operating income was generated by energy sales (such as power generation and steam). The treatment capacity increased by 11% to 18% after the recalculation of the incineration capacity and has remained consistently above 90% in most facilities to date. In order to solve the problem of high calorific value waste, wastewater, leachate, and clean water should be mixed and incinerated, and heat recovery should be performed through a water-cooled grate and water cooling wall installation. Twenty-five of the 38 incineration facilities (about 70%) are due for a major repair. After the main repair of the facility, the operation rate is expected to increase and the operating cost is expected to decline due to energy recovery. Inspection and repair should be carried out in a timely manner to increase incineration and heat energy recovery efficiencies.

  • 최근 기후변화에 따른 이상기상의 증대는 안정적인 벼 생산에 위협을 주고 있으며, 출수기의 변동은 기후 변화 적응에 주요한 요인 중 하나이다. 2022년도에는 이앙부터 출수까지의 생육기간 동안 평균기온이 증가하였음에도 출수기가 5일 이상 지연되는 등의 특이적인 결과를 보였으며, 일반적인 생육단계별로 온도가 출수에 미치는 반응을 고려해 결과를 해석할 수 없었다. 이는 생육단계에 따른 온도의 반응이 다를 수 있어 벼의 출수기 변동을 정확하게 판단하는 것에 한계가 있을 것으로 생각되었으며 또한 일장조건별로 출수 반응에 미치는 온도의 영향이 달라질 수 있기 때문에 이를 구명하는 연구가 필요할 것으로 보인다. 또한 생육단계별로 일사량, 일조시간 등 일사 조건에 따른 생육 발달 변화가 출수 반응에 미치는 영향에 대한 연구가 미흡한 상황으로 이에 대한 연구가 필요할 것으로 생각된다.

  • Up to date cosmetic OEM/ODM (original equipment manufacturing/original development manufacturing) industry receives attention as a future growth engine due to steady growth. However, because of limited research and development capability, many companies have employed commercial management platforms specialized for large-sized companies; thus, overall system effectiveness and efficiency is low. Especially, MRP (material requirement planning) system introduced originally in 1970s is employed to calculate the requirement of the parts. However, dynamic nature of production lead time usually results in incorrect requirements. In addition, its algorithm does not consider the capability of the production resources. Also, because the commercial MRP system calculates all subcomponent for fixed period, the more goods have subcomponent, the slower calculation is. Therefore, conventional MRP system cannot respond complicated situation in time. In this study, we will suggest a new method that can respond to complicated situations resulting from short lead time and urgent production order in Korean cosmetic market. In particular, a distributed MRP system is proposed, that consists of multi-functional and operational modules, based on the characteristic of the BOM (bill of material). The distributed MRP system divides components (i.e. products and parts) into several fields and decrease the problem size; thus, we can respond to dynamically changed data any time. Through this solution, we can order components quickly, adjust schedules and planned quantity, and manage stocks reasonably. In addition, a prototype of the distributed MRP system is presented in this paper, in which ERP (enterprise resource planning) sever data is associated with an excel spreadsheet via MSsql. System user interface is implemented by a VBA (visual basic for applications) tool. According to a case study, response rate for delivery and planning achievement rate were enhanced about 20%, and inventory turnover was also decreased. Consequently, the proposed system improves overall profit.

  • In recent years, business environment is faced with multi uncertainty that have not been suffered in the past. As supply chain is getting expanded and longer, the flow of information, material and production is also being complicated. It is well known that development service industry using application software has various uncertainty in random events such as supply and demand fluctuation of developer's capcity, project effective date after winning a contract, manpower cost (or revenue), subcontract cost (or purchase), and overrun due to developer's skill-level. This study intends to social contribution through attempts to optimize enterprise's goal by supply chain management platform to balance demand and supply and stochastic programming which is basically applied in order to solve uncertainty considering economical and operational risk at solution supplier. In Particular, this study emphasizes to determine allocation of internal and external manpower of developers using S&OP (Sales & Operations Planning) as monthly resource input has constraint on resource's capability that shared in industry or task. This study is to verify how Stochastic Programming such as Markowitz's MV (Mean Variance) model or 2-Stage Recourse Model is flexible and efficient than Deterministic Programming in software enterprise field by experiment with process and data from service industry which is manufacturing software and performing projects. In addition, this study is also to analysis how profit and labor input plan according to scope of uncertainty is changed based on Pareto Optimal, then lastly it is to enumerate limitation of the study extracted drawback which can be happened in real business environment and to contribute direction in future research considering another applicable methodology.

  • This study was conducted as a basic data for preparing future management alternatives by analyzing the status and characteristics of invasive alien plants by land-use type based on the formation of a new town in Goyang Siksa district. As a result, the invasive alien plants in the Goyang Siksa district were 20 families 46 genera 57 taxa; according to the land-use type, the residential area(Wi City apartment complex) is 7 families 10 genera 12 taxa, the public facilities area(Dongguk University campus) is 17 families 40 genera 47 taxa, the mixed forest is 5 families 10 genera 10 taxa, the rice paddy is 5 families 6 genera 7 taxa, river(Mt. Gyeondal creek) is 7 families 13 genera 15 taxa were appeared. The life-form of invasive alien plants in Goyang Siksa district is annuals, the origin is America, the introduction time is third period(1962~the present), and the diffusion grade is wide spread(5 grade) species. It was higher than other types. The naturalization index by location was 31.9% in river(Mt. Gyeondal creek), 21.2% in rice paddy, 16.7% in mixed forest, 15.5% in public facilities area(Dongguk University campus), and 8.5% in residential area(Wi City apartment complex). As a result of comparing the naturalization index by regions with the previous studies, it is judged that there are differences due to the environment such as urbanization progress, size, area, population inflow and location conditions. Although many new towns have been established to date, there is a lack of research on flora (including invasive alien plants) as a basic data for preparing management alternatives. Therefore, Through this study, basic data on the management of exotic plants by land use unit in urban areas can be provided.

  • Pulmonary lymphangioleiomyomatosis is a chronic destruct8ive disease of the lung affecting women of childbearing ages which eventually leads to respiratory failure. Lung transplantation is the only conclusive therapeutic measure because this disease responds poorly to other therapies, To date only a few reports in the literature describes the clinical experience of the bilateral sequential lung transplantation of this rare condition. We performed a bilateral sequential lung transplantation on a 32-year-old woman suffering from lymphangioleiomyo-matosisw. The heart-lung block was harvested from a 51-year-old donor. We transplanted the left lung first through the clam-shell incision. As the hemodynamics deteriorated suddenly during the dissection of the right lung the right lung was transplanted under the cardio-pulmonary bypass. Although the patient's lung function was initially satisfactory the patient died of sepsis and subsequent cardiogenic shock at the postoperative 18th day. Autopsy findings showed infection of Candida albicans on the pericardium and the left lung which had been initiated possibly from the left bronchial anastomosis site,. Through detailed review of the clinical course we concluded that lung transplantation could have been performed safely on this disease provided that early diagnosis and proper management or the oppor-tunistic infection have been carried out.
