  • Objectives: By grasping trends in research, technology, and general characteristics of learning support tools, this study was conducted to present a model for research on Korean Medicine (KM) to make use of information technology to support teaching and learning. The purpose is to improve the future clinical competence of medical personnel, which is directly linked to national health. Methods: With papers and patents published up to 2011 as the objects, 438 papers were extracted from "Web of Science" and 313 patents were extracted from the WIPS database (DB). Descriptive analysis and network analysis were conducted on the annual developments, academic journals, and research fields of the papers, patents searched were subjected to quantitative analysis per application year, nation, and technology, and an activity index (AI) was calculated. Results: First, research on medical learning support tools has continued to increase and is active in the fields of computer engineering, education research, and surgery. Second, the largest number of patent applications on medical learning support tools were made in the United States, South Korea, and Japan in this order, and the securement of remediation technology-centered patents, rather than basic/essential patents, seemed possible. Third, when the results of the analysis of research trends were comprehensively analyzed, international research on e-PBL- and medical simulation-centered medical learning support tools was seen to expand continuously to improve the clinical competence of medical personnel, which is directly linked to national health. Conclusions: The KM learning support tool model proposed in the present study is expected to be applicable to computer-based tests at KM schools and to be able to replace certain functions of national KM doctor license examinations once its problem DB, e-PBL, and TKM simulator have been constructed. This learning support tool will undergo a standardization process in the future.

  • Grouping of the Korean traditional rice processed foods and their historical background in development were surveyed, principally being concentrated on the current topics reported on the rice-processed foods such as rice cakes and rice cookies. Rice-processed foods could be classified into seven groups according to the literature reported so far: rice gruels, boiled rices, rice cakes, alcoholic liquors, non-alcoholic beverages and seasonings. Among them, rice gruels and boiled rices were further divided into seven to eight groups based on their characteristics together with added materials. Eighty one names of rice cakes were reported in the literature, however it might be condensed to five groups according to their processing methods. Ninety different alcoholic liquors were found and arranged according to the cited period in the literature. Five kinds of rice cookies and nine kinds of non-alcoholic beverages were found in the literature. These are maintained until today with almost identical methods of preparation as described in the old literature. The scientific research results on the Korean traditional rice cakes and cookies published in the literatures were reviewed. A total of forty one research papers were collected: twenty seven papers on rice cakes and fourteen papers on rice cookies. Most of the researches were concerned to the processing conditions. The author felt deeply some too short of researches in the physicochemical changes during processing, the maintenance of the products quality and the industrialization of the traditional processing methods in rice foods.

  • According to appearance of a new competitive factor, as 'Green', Green Logistics becomes the important evaluation factor for many firms in emerging competitive environment. Despite this importance, the recognition level of Korean firms on Green Logistics lags behind that of leading companies in developed countries. In addition, the literature studies and practical strategies for systematic management control plans are very insufficient. In this paper, we establish decision making framework of Green Logistics by using ANP(analytic network process). Specifically, we suggest at first the overall concepts and issues of Green Logistics through literature studies. Next, we derive 6 clusters and 21 components forming the strategic green logistics, and then we conduct surveys for pairwise comparison of experts on Green Logistics and compute relative weights of the clusters, components and altanatives considering the feedback structure. We expect that the results of this study will be very helpful for managers to make strategic decisions.

  • Purpose of the War history's study is getting instruction by analyzing victory and defeat factor. This study is studied by qualitative form in war study mainly. In case recording literature is full, victory and defeat factor analysis is easy, but occasionally definite analysis that recording literature is feeble is difficult. Also, when it is battle result that escape common sense, about victory and defeat factor, various estimations are brought. As such example, there is Myeong-Ryang sea-battle at Japanese Invasion of Korea in 1592 and Korea(Cho-Sun) naval forces did big victory in 13 vs. 133 numerical inferiorities. This study presented method of study that using agent based simulation model for quantitative analysis of these victory and defeat factor.

  • ATM network design procedure is different from the current circuit or packet networks design procedure because of the variety of the offered services and the variability of requested bandwidth for each connection of ATM network. A number of optimization models for the link dimensioning of ATM network design have been proposed in the literature. However, most of the literature did not consider the modularity of resources allocated to a transmission path and the non-bifurcation of a VP link over the more than one TP, which are standardized in recent ITU-T Recommendations. In thIs paper, we propose a mathematical model for link dimensioning of ATM networks, based on the network synthesis method and a generalized bin-packing problem. The suggested model satisfies the constraints mentioned in the ITU-T Recommendations. We also propose efficient and practical algorithms for the suggested model. Computational experiment shows that the suggested algorithm gives efficient solutions even for moderate and large-sized networks within reasonable time.

  • In the era of Joseon Dynasty there was a national system of postmortem investigation with literatures of postmortem inspection. The author reviewed the postmortem findings in the literature(Shinjumoowonrok) to compare with recent knowledges of forensic medicine. Characteristics of old system of postmortem investigation was three instance investigation system and was carried out only with a postmortem inspection without autopsy. The postmortem findings described in the old literature were about various kinds of death, such as cases of suicide and homicide and natural and unnatural death. Most of postmortem findings in the Shinjumoowonrok were accurate and reasonable in the aspect of recent knowledges of forensic medicine.

  • The objective of this study is to evaluate the effects of sharing uncertain yield information with a downstream supply chain player. We are interested in understanding how the amount of yield uncertainty affects the supply-side benefits and/or costs, which has not been considered in the literature, in addition to the customer-side benefits. With that purpose, this work evaluates a supplier who provides yield information in comparison with another supplier who shares no information. We simulate an order-up-to type heuristic policy that is adapted from the literature and reasonably modified to represent yield information sharing with error. From the simulation study, we argue that the customer would experience cost reduction, but the cost for supplier's inventory is increasing when sharing yield information. Furthermore, the amount of benefits and costs are situational and affected by level of yield uncertainty and demand variance. Based on the simulation study, we finally make several recommendations for the supply-side approaches to yield information sharing.

  • Bisphenol A (BPA) is an endocrine-disrupting chemical that is capable of interfering with the normal function of the endocrine system in the body. Exposure to this chemical from BPA-containing materials and the environment is associated with deleterious health effects, including male reproductive abnormalities. A search of the literature demonstrated that BPA, as a toxicant, directly affects the cellular oxidative stress response machinery. Because of its hormone-like properties, it can also bind with specific receptors in target cells. Therefore, the tissue-specific effects of BPA mostly depend on its endocrine-disrupting capabilities and the expression of those particular receptors in target cells. Although studies have shown the possible mechanisms of BPA action in various cell types, a clear consensus has yet to be established. In this review, we summarize the mechanisms of BPA action in spermatozoa by compiling existing information in the literature.

  • Objectives : Acupoint LU6 (Gongchoe) is known as an acupoint for the treatment of pain and bleeding caused by hemorrhoids. The purpose of this study was to critically review acupoint LU6 for treating hemorrhoids. Methods : We searched both ancient and modern literature of acupuncture and moxibustion using keywords "Gongchoe" and "hemorrhoids". We further performed an online ancient literature search for crosscheck. The searched literature was stratified by country (Korea, China, and Japan), and data were organized chronologically. Concerning literature related to hemorrhoids, data based on acupuncture treatment were compiled. Results : The bone proportional measurement of the forearm had been 12.5 cun until the Qing Dynasty but was recorded as 10 cun in "Shinkyushinzui," and the majority of modern Japanese and Korean literature indicated it as 10 cun. Gongchoe for treating hemorrhoids has been reported in the literature, including "Shinkyushinzui" (Japan, 1941), "Shiyoungzongguozhenjiujingxuexue" (Taiwan, 1963), "Gyeonghyeolhak" (Korea, 1971), and "Jinzhenmeihuashichao" (China, late Qing dynasty), but except "Jinzhenmeihuashichao", the location is different from the World Health Organization (WHO) standard acupoint location as it is 7 cun from the wrist out of 10 cun of the forearm bone proportional measurement. In addition, classical guides published until the Qing Dynasty did not report acupoint LU6 for the treatment of hemorrhoids. Conclusions : It is necessary to distinguish between Gongchoe in "Shinkyushinzui" and LU6 in WHO standard acupuncture point locations. Gongchoe (LU6)'s primary treatment for hemorrhoids has not been described in the classical literature, and further clinical evidence is needed to support it. When using Gongchoe for hemorrhoids, we should consider that the location of Gongchoe is closer to the LU5 than the standard acupuncture point locations and it is meaningful not only for treatment but also for diagnosis.
