The systematic management of technology infrastructure increasingly becomes critical as it represents the driving power for creating competitive advantage of nations and enterprises. In this sense, public facility and equipment, which is one major asset of technology infrastructure, should be managed effectively, systematically and efficiently to increase its overall equipment effectiveness. However, the manual and off-line communication was the unique way to communicate between the suppliers who provide facilities in the public sector and the customers who utilize the facilities in the industrial sector. This communication way caused invisibility of available usage time and increase of idle time, thereby decreasing the equipment effectiveness. This paper presents an web-based scheduling system that enables real-time collaboration and information sharing for increasing the equipment effectiveness. The designed system performs scheduling, facility management, order management and customer relationship management in an on-line platform, and carries out the processing and storing of relevant information in an integrated database. The paper includes a development approach to identify business process models and standardized system models by using object-modeling technique. The deliverable of the present work will contribute to increasing the equipment effectiveness by enhancing visibility, transparency and predictability by means of the integration with a legacy Enterprise Resource Planning.

The objective of this paper is to suggest structural design for the long-life housing apartment complex to save the construction cost. The key is to use unavailable underground space due to bearing walls or bad configuration of columns in apartments as the parking space. Therefore, the structural plan of apartment buildings considering the parking section in the underground should be designed. After analytical resutls of three cases, it is significant effect in saving construction cost.

Module coordination(分數), which is crucially relevant to plan shape of a fortress and the location of its gates and chis(雉, protruding posts), have not been thoroughly studied, despite its importance in fortress system. While plan shape of Goryeo fortress features orderly placement of gates and chis, under medium-sized Joseon fortress doesn’t follow it strictly. As a result, fortresses with various plan shapes greatly outnumber those of Goryeo. Especially, Gimhaeeupseong Fortress, which is a large-scale town wall, shows such a complicated plan shape, making it difficult to figure out its modular coordination. Presumably, the reason for Joseon fortress’ complicated plan shapes, which doesn’t follow the orderly modular coordination, is thought to be in its various geographical conditions. Also, it seems that the building of fortress with such various and complicated plan shapes was to deter enemies from intruding by confusing them. And various plan shapes of fortress are also figured out to be pertinent to street system of towns and positions of public offices.

경주 방사성폐기물 처분시설은 향후 80만 포장물을 처분할 계획이며 다양한 처분방식 및 관리형태를 가진 복합계가 될 것 이다. 본 논문에서는 전체부지 처분용량(80만 포장물) 처분시설의 단계별 개발에 따른 영향을 평가하기 위하여 처분시설 종 합개발계획(안)에 따른 예비안전성평가를 수행하였다. 각 시나리오에 대한 안전성평가결과 처분시설의 성능목표치를 만족 하였다. 다만, 전체처분시설의 안전성 평가결과에 중준위 방사성폐기물로 인하여 1단계 동굴 처분시설이 가장 크게 영향을 미치므로 처분시설의 안전성 향상을 위하여 처분방사능량제한 설정 등 관리방안이 필요하다. Safety Case 단계별 구축을 통 하여 중·저준위 방사성폐기물 처분시설 종합개발 과정에서 인지된 불확실성을 저감하여 안전성을 증진 시킬 수 있을 것으 로 판단된다.

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.

Lentinula edodes, shiitake, is a very important non-timber forest product that has been consumed more than 50,000 tons every year in Republic of Korea. However, the rapid increase of imported shiitake media from China has eroded domestic goods’ competitiveness. The domestic shiitake industry has faced this situation and has exerted great efforts to localizing shiitake spawn while encouraging the growers to utilize the domestic shiiake spawn. To address such a challenge, the “Golden Seed Project” was designed, with an objective to expand the market share of domestic spawn and to increase the exports of the domestic spawn within the period of 2013 to 2021. Under the project, two projects and five commissioned sub-projects have been conducted up to now, making some outcomes. Protections of two new varieties (Sanmaru 2-ho and Sanbaekhyang) of shiitake, whose cultivation periods were shortened up to 20 days compared to the existing ones, have been applied. Also, there have been three cases of technology transfers of new varieties to private enterprises, all of which contributed to disseminating domestic spawn. Besides, the research team has held public fairs and presentations of new shiitake varieties in a regular basis, while operating a total of 24 test beds consisting of log cultivation and sawdust bag cultivation. Meanwhile, other research projects have been done to identify fruit-body ingredients and the properties of molecular markers of mating types and to monitor diseases and pests. The second stage of “Golden Seed Project” aims to increase the share of domestic spawn in the domestic market, up to more than 70%.

Wholesale beef price is the critical factor for determining Korean native cattle, Hanwoo, farm’s income in short-term. Wholesale beef price has seasonality due to high demand in Korean traditional holidays such as Korean thanksgiving day and lunar new year’s day. Therefore, it is important to make reproduction and marketing plans for Korean Hanwoo farmers, in order to increase their farm income. However, there is no study available on changes in the expected farm income depending on reproduction and marketing schedules. This study analyzed the expected farm income per head depending on the monthly-based marketing schedules. The analysis was conducted based on the seasonality of wholesale beef price, reproduction efficiency, operating costs, relationship between carcass grade and slaughter age. The result shows that slaughter Hanwoo at the age of 29 months-old in August and January generating the highest expected farm income per head.

In this paper we have tackled the outstanding inventory planning problems over new product launching period in a more holistic manner by addressing first the definition of efficient business rules to effectively control and reduce the inventory risks followed by the rigorous explanations on the implementation guide on suggested inventory planning rules. It is not unusual for many companies in the consumer electronics market to make a great effort to reduce the time to launch a new product because the ability to bring out higher performing products in such a short time period greatly increases the probability for them to remain competitive in the high tech market. Among so many newly developed products, those products with new features and technologies appeal to many potential customers while products which fail to win customers by design and prices rapidly disappear in the market. To adapt to this business environment, those companies have been trying to find the answer to minimize the inventory of old products so they can move to next generation products quickly with less obsolete material . In the experimental implementation of our rule-based inventory planning, Company ‘S’ reduced the inventory cost for the outgoing products as low as 49% of its peak level of its preceding product version in just 5 month after the adoption of rule-based inventory planning process and system. This paper concluded the subject with a suggestion that the best performance of rule-based inventory planning is guaranteed not from one-time campaign of process improvement along with system development but the decision maker’s continuing support and attention even without seeing any upcoming business crisis.

본 연구에서는 소년범들 중에서도 범죄를 사전에 계획한 범죄자들에 주목하여, 소년범의 배경 특성 및 범행 내용을 다각도로 분석하고, 특히 범죄를 계획하지 않은 소년범들과의 비교를 통해 범죄 계획성에 영향을 미치는 요인들에 대해 살펴보았다. 이를 위해 경찰서에 입건된 소년범 총 279명을 바탕으로 분석하였다. 본 연구 결과, 우선 두 집단 사이에 성별, 연령 및 인성 검사 결과에 있어서는 차이가 나타나지 않았다. 그러나 배경 특성 및 범행 특성에 있어서는 여러 가지 차이점이 나타났다. 우선 범행을 사전에 계획한 비행청소년들이 그렇지 않은 비행청소년들보다 비행을 저질러 경찰서에 출입하는 친구가 더 많으며, 술을 더 자주 마시고, 알코올을 포함한 약물남용에 해당되는 비율 역시 2배 이상 높은 것으로 나타났다. 범죄와 관련된 태도에 있어서도 뚜렷한 차이가 나타났는데, 범행을 사전에 계획한 비행청소년들의 경우 준법의식이 없고, 인생목표에 있어 현실성이 없고 실제로 노력하지 않으며, 어려운 일에 대한 대처능력이 없고, 경찰서에서의 면담 태도가 불량한 경우가 훨씬 더 많았다. 또한 범행을 사전에 계획한 비행청소년들이 그렇지 않은 비행청소년들보다 총 전과 수는 더 많지 않으나, 절도 전력이 있는 비율은 두 배 가량 많았고, 본 비행에 있어 절도, 대물범죄를 저지른 비율이 훨씬 더 높았으며, 장물처리 등의 비행수법에 대해 더 잘 알고 있었다. 그 외에도 범죄 계획성 여부에 따라 범행 장소 및 가해자-피해자 관계, 공범 수에 있어서도 차이가 나타났다. 마지막으로 본 연구 결과를 토대로, 소년범의 재범 방지를 위한 실질적 방안에 대해 논의하였다.

For air express service providers offering various express delivery services such as overnight delivery and next-business day delivery services, establishing quickly cargo loading plans is one of important issues owing to the characteristics of air express business, i.e., a short amount of time is available to complete all cargo loading operations before flight departure after receiving air express containers, pallets and bulks. On the other hand, one of major concerns in the air cargo loading planning is to make a plan that insures the stability of an aircraft to avoid take-off, flight, and landing accidents. To this end, this paper considers an air cargo loading planning problem, which is the problem of determining locations in the aircraft cargo space where air containers, pallets and bulks to be loaded while insuring the aircraft stability, motivated from DHL and Air Hong Kong. The objective of the problem is to maximize the total revenue gained from loading air express containers, pallets and bulks. To solve the problem, this paper suggests a simulated annealing algorithm to overcome impracticality of the integer programming model developed by a previous study requiring excessive computation time. The results of computational experiments show that the heuristic algorithm is a viable tool for establishing express cargo loading plans as giving robust and good solutions in a short amount of computation time. Scenario analyses are performed to investigate the effect of the current activities of air express carriers on the revenue change and to draw practical implications for air express service providers.

This paper aimed to identify the units of measuring scale in Hwangnyongsa temple planning with the published excavation survey reports. Hwangyongsa temple site was planned under Silla Capital’s urban planning in 6～7C, its full size was 800×800, and main temple was 400×515 of Goguryeo’s system of measurement. Main hall was located in the center of Hwangnyongsa temple site, and its location could be seen that there was the arrangement of main temple divided into 3 : 2. Building plan measuring units proved to be 351～356㎜ and 294～ 296㎜ by analyzing measured data of remains. Lecture hall and Wooden pagoda were rebuilt by using the ancestors’ units of measuring scale again and Bell hall was not planned by Tang’s system of measurement in middle of 8C. In this respect, it would be important to have a deliberate attitude and lay down stereotypes on research of the units of measuring scale in ancient architecture.

This paper considers the allocation and engagement scheduling problem of interceptor missiles, and the problem was formulated by using MIP (mixed integer programming) in the previous research. The objective of the model is the maximization of total intercept altitude instead of the more conventional objective such as the minimization of surviving target value. The concept of the time window was used to model the engagement situation and a continuous time is assumed for flying times of the both missiles. The MIP formulation of the problem is very complex due to the complexity of the real problem itself. Hence, the finding of an efficient optimal solution procedure seems to be difficult. In this paper, an efficient genetic algorithm is developed by improving a general genetic algorithm. The improvement is achieved by carefully analyzing the structure of the formulation. Specifically, the new algorithm includes an enhanced repair process and a crossover operation which utilizes the idea of the PSO (particle swarm optimization). Then, the algorithm is throughly tested on 50 randomly generated engagement scenarios, and its performance is compared with that of a commercial package and a more general genetic algorithm, respectively. The results indicate that the new algorithm consistently performs better than a general genetic algorithm. Also, the new algorithm generates much better results than those by the commercial package on several test cases when the execution time of the commercial package is limited to 8,000 seconds, which is about two hours and 13 minutes. Moreover, it obtains a solution within 0.13 ~33.34 seconds depending on the size of scenarios.

PURPOSES: The demand for extending national highways is increasing, but traffic monitoring is hindered because of resource limitations. Hence, this study classified highway segments into 5 types to improve the efficiency of short-term traffic count planning. METHODS : The traffic volume trends of 880 highway segments were classified through R-squared and linear regression analyses; the steadiness of traffic volume trends was evaluated through coefficient of variance (COV), and the normality of the data were determined through the Shapiro-Wilk W-test. RESULTS : Of the 880 segments, 574 segments had relatively low COV and were classified as type 1 segments, and 123 and 64 segments with increasing and decreasing traffic volume trends were classified as type 2 and type 3 segments, respectively; 80 segments that failed the normality test were classified as type 4, and the remaining 39 were classified as type 5 segments. CONCLUSIONS : A theoretical basis for biennial count planning was established. Biennial count is recommended for types 1~4 because their mean absolute percentage errors (MAPEs) are approximately 10%. For type 5 (MAPE =19.26%), the conventional annual count can be continued. The results of this analysis can reduce the traffic monitoring budget.
