In a planning stage, the assessment system is required to select the proper alternative, reflected the environmental affects such as energy, $CO_2$ and $SO_x$. Unit of energy consumption, $CO_2$ emission and $SO_x$ emission among various assessment systems could be effectively utilized to select the better alternative among various building types. But researches for these areas has not been conducted systematically, but limitedly and sporadically. In this paper, it aimed at providing the unit of energy consumption, $CO_2$ emission and $SO_x$ emission to evaluate the environmental affects between the steel-structured apartment building and wall-typed apartment building. For this, the input-output analysis could be utilized in the construction stage with two-type apartment housing. This approach can be utilized to compare the various alternatives in aspect of the energy consumption and the environment affect, and to select the relatively better alternative. This study found that the unit of energy, $CO_2$ and $SO_x$ of the steel-structured apartment building is lower than that of the wall-typed building

The objective of this study was to prepare the base on which Korean food can become a globally important health food. A focus group interview was conducted with a nutritionist and professor of food and nutrition to select the Korean food for a healthy menu. Five main categories were established to select a healthy menu based on the Korean food philosophy, including Korean food made from beans, Korean food made using fermentation, Korean food made using various colors, Korean food with high dietary fiber, and Korean food made with abundant unsaturated fatty acids. The 52 healthy menu items selected based on these standards were composed of easily available food materials. The efficacy of food materials described in Sikryochanyo, the traditional Chosun dietary therapy, was checked to verify the efficacy of this healthy menu. This study demonstrated that basic materials can be efficiently used to enable citizens to select Korean food as an international health food. As such, the results can be utilized to publicize Korean food as a healthy food.

The objective of this research is to select the most effective technique from AMT (Advanced Manufacturing Technologies) and IMP (Innovative Management Practices) for improving manufacturing performance in shipbuilding enterprises. The research consists of several principal steps. The first step is to design critical criteria in evaluating manufacturing performance in shipbuilding enterprises. The second step is to develop sub-criteria of the critical criteria. The third step is to develop a four level AHP (Analytic Hierarchy Process) structure using the critical criteria, sub-criteria and techniques from AMT and IMP. The fourth step is to develope the pairwise comparison matrix by each level of AHP structure, which was based on survey data collected at the H heavy industry. And the last step is to select the most effective technique from AMT and IMP by using AHP analysis. The results of AHP analysis did not show clear difference in priority between techniques of AMT and IMP in terms of manufacturing performance of the shipbuilding enterprise. Thus, each critical criterion was assigned modified weights and examined the priority change of techniques by conducting performance sensitivity analysis.

선형배정문제 (LAP)와 선형병목배정문제 (LBAP)는 다항시간으로 최적 해를 구하는 알고리즘이 알려져 있지 않은 NP-난제로 분류되어 메타휴리스틱 방법이나 O(m⁴) 계산 복잡도의 선형계획법 (LP) 소프트웨어 패키지나 헝가리안 알고리즘 (HA)을 적용하고 있다. 본 논문은 LAP와 LBAP에 대해 O(mn)=O(m²),m=n 복잡도의 다항시간 알고리즘을 제안하였다. LAP에 대해서는 선택-삭제 방법을, LBAP에 대해서는 삭제-선택 방법을 단순히 적용하였다. 모든 데이터에 적합한 유일한 알고리즘이 존재하지 않는 실험 데이터에 제안된 알고리즘을 적용한 결과, 제안된 알고리즘은 모든 데이터에 대해 최적 해를 구할 수 있었다.

Many universities are searching for educational methods to cultivate problem-solving ability and cooperative learning ability or already trying to implement them. Problem Based Learning(PBL) and Action Learning(AL) are effective teaching and learning methods to cultivate men of talent qualified for problem-solving and cooperative learning abilities that universities are seeking after. PBL and AL have something in common in that learning is accomplished while learners are solving the authentic problem. But, in spite of this similarity, PBL and AL have differences. However, most literatures and cases on these two models introduce only the outline of commons and differences and do not provide teachers with actual helping aids to select a model appropriate for the actual design or operation of classes. Accordingly, many teachers usually select and utilize a familiar model rather than select a proper model to the nature of a subject and the educational goal. Teaching and learning methods or learning environment should be selected appropriately to the educational goal. This study indicates the characteristics of PBL and AL that are being introduced and utilized as a principal teaching and learning method of college education and then shows how this method can be realized in the university by comparing the cases of classes applied in two methods.

This study focuses on proposing measures for the reasonable development of offshore wind farms using the case of Norway, which was the first nation in the world to build a floating offshore wind farm of 80 MW or more. Norwegian authorities conducted a strategic environment assessment in 2012 to select offshore wind farm sites, discovered 15 potential sites, and finally decided on two designated sites in 2020. Based on various survey data such as seabirds, marine environment, and fishing activities, scientific-based spatial analysis was conducted to select additional offshore wind farm sites in line with future development plans. In addition, a government-led steering committee and advisory group have established marine spatial plans since 2002. Therefore, it will be possible to listen to and coordinate the opinions of stakeholders by using the steering committee and advisory group for offshore wind power development. By examining the case of Norway, we suggest the following policy points that can achieve carbon neutrality and develop sustainable offshore wind farms: 1. Establish a government-led steering committee and advisory group that can select potential sites for offshore wind farms by coordinating the opinions of stakeholders 2. Induce efficient and sequential offshore wind farm development by using various survey data and scientific-based spatial analysis.

선회다짐기를 이용하여 아스팔트 혼합물의 배합설계를 하는 경우 선회다짐기의 설계 다짐횟수가 필요하다. 본 연구는 이러한 선회다짐기의 설계 다짐횟수를 결정하는데 그 목적이 있다. 선회다짐횟수의 선정을 위하여 세 가지 방법을 이용하였다. 첫 번째 방법은 Marshall 다짐기로 75회 다짐된 혼합물의 밀도와 동일한 밀도를 주는 선회다짐횟수를 선정하는 것이며, 두 번째 방법은 Marshall 다짐기로 75회 다짐된 혼합물의 변형강도와 동일한 변형강도를 주는 선회다짐횟수를 선정하는 것이다. 세 번째 방법은 선회다짐횟수에 따른 공극률을 측정하여 공극률 4%에 해당하는 다짐횟수를 찾아 결정하는 방법이다. 실내 실험을 위해 총 10가지 종류의 아스팔트 혼합물(1가지 골재$\times$10가지 입도$\times$1가지 아스팔트 바인더)이 제작되었다. 세 가지 방법을 종합한 결과, 아스팔트 혼합물의 배합설계를 위한 설계 선회다짐횟수는 100회로 결정되었다. 이러한 결과는 외국에서 사용되고 있는 설계 선회다짐횟수와 유사한 경향을 보이는 결과로, 향후 국내에서 선회다짐기를 이용한 아스팔트 혼합물의 배합설계가 이루어질 경우 적용이 가능할 것으로 판단된다.
