This paper or article is about bamboo products from Damyang that have been degenerated by the threat of Chinese low-cost products. Comparing the products from Damyang and China, we could point out four problems and come up with solutions. Firstly, we need strong and specific storytelling based on historical facts and various research to boost the bamboo industry. In order to introduce interesting storytelling to the public, it is also necessary to train some good-quality workers. The public would be more familiar with the bamboo products from Damyang than Chinese products. Secondly, technologies used for bamboo products from Damyang are extremely behind the times. Skill shortages for bamboo products caused to create unattractive products to the public for approximately 30 years. Thus, we need to acquire advanced technologies from abroad as well as to develop our own. Thirdly, Even though attractive bamboo products would be produced with advanced technologies, workers in bamboo industry lack knowledge of distribution channels and marketing strategy so that there is no way to introduce their products effectively to the consumers. Therefore, government agencies or marketers should educate workers to help running their business successfully. Finally, bamboo products have been fashion and living items for some specific consumers for the last years. However, we need to create variously new types of bamboo products through the collaboration with a wide range of artists to be widely appealing. In conclusion, it is important to be aware of the problems and solutions above. The 17th Bamboo Expo in Damyang will be a great opportunity to introduce Korean bamboo products in worldwide and develop the bamboo industry.

The purpose of this study was to identify the determinants of traditional food perception, by taking the generation effect into account. This study also analyzed the preference patterns of traditional snacks and the strength as well as direction of improvement for traditional foods. Data were collected from 304 housewives living in the Baeong-Nyeong-Do island. Regression analysis showed that the determinants of traditional food perception varied depending on the generation of housewives. In the 30s age subgroup, income and family type were significantly related with the degree of traditional food perception. In the 40s age subgroup, household income, education, and hometown location were significant, whereas household income, family type, number of years of life spent in the Baeong-Nyeong-Do island, hometown location were the significant factors in the 50s and 60s age subgroup. The results of factor analysis showed that there were three preference patterns of traditional snacks. The results of chi-square analysis proved that foods for strength, and direction of improvement for traditional foods were different among the generation groups. In this article, similarities and differences between determinants of traditional foods, the strength and direction of improvement for traditional foods are discussed, and their implications for nutritionists as well as food marketers are provided.

There are no reliable data about the effect on the baking industry in Korea yet. The damage caused by the product's aging is so much in the confectionary and baking industries. Therefore, the aging of bread is an economical problem which determines its commercial lifespan. In order to solve out this aging problem, this article dealt with the factors which give rise to the effect of starch on the aging and its inhibitory methods. 1. Control of the moisture content : Because the aging of starch occurs at 30~60% of moisture most frequently, controlling the moisture content above or below the above percentage can help restrain the aging to a certain degree. 2. Addition of sugars : The sugars become hydrated through hydrogenation with the moisture in the food. Thus, the sugars suppress the phenomenon of crumbling inside the food acting as a kind of dehydrator. 3. Use of an emulsifying agent : The emulsifying agent increases the stability of starch colloid liquid and suppresses the precipitation of starch molecules and the formation of crystallized range to prevent aging. 4. Method by freezing : The aging of starch does hardly occur reaching -2$0^{\circ}C$~-3$0^{\circ}C$ below zero. 5. Maintenance of warm condition : The freshness of bread is maintained at the 80% of humidity at 5$0^{\circ}C$.

Korean Volunteer Fire Departments are the representative disaster-related civilian organizations which are based on "Firefighting Framework Act Article 37"and ordinance for complementing the lack of fire-fighting personnel and volunteer and they play a part as community safety keepers. They are operated by the National funding, but cannot be defined as the organization in governmental sources completely or pure volunteer organization in terms of its founding purpose and activities. In these special characteristics, some Volunteer Fire Departments play an important role in Civilian Volunteer Disaster Prevention by being managed effectively, but the others do not. There can be many cause-analyses about this difference. They aren't profit-making organizations and are groups which have no compulsion. So it is important that who the leader is, and what type of leadership he has. By solving this bias by considering these characteristics, in this study we make them perform the center role of community safety network through analyzing the existing status and problems of volunteer fire department education and customized training program reengineering to meet class-specific and regional level.

Objectives : The purpose of this systematic review was to overview and evaluate the current state of the usage of bee venom acupuncture. Methods : We collected 173 articles on bee venom acupuncture(BVA) clinical study from eight electronic databases from January 2002 to June 2013. Results : BVA was used in musculoskeletal diseases for 66 %, and the chosen acupoints were various. The ratio of the reports which had collected below 10 cases was 43 %. The concomitant treatment and evaluation tools showed diversity in each article. Conclusions : Bee venom clinical study shows the lack of unity and consistent regulation, and has low clinical cases. Future studies should correct these limits and promote more varied research to develop the therapy of bee venom acupuncture.

Low-power and lossy networks (LLNs) comprised of thousands of embedded networking devices can be used in a variety of applications, such as smart grid automated metering infrastructures (AMIs) and wireless sensor networks. Connecting these LLNs to the Internet has even greater potential, leading to the emerging concept of the Internet of Things (IoT). With the goal of integrating LLNs into IoT, the IETF has recently standardized RPL and 6LoWPAN to allow the use of IPv6 on LLNs. Although there already exist several studies on the the performance of RPL and embedded IPv6 stack in LLN, performance measurement and characterization of TCP over RPL in multihop LLNs is yet to be studied. In this article, we present a comprehensive experimental study on the performance of TCP over RPL in an embedded IPv6-based LLN running over a 30-node multihop IEEE 802.15.4 testbed network. Our results and findings are aimed at investigating how embedded TCP interoperates with common Linux TCP and underlying RPL (and vice versa), which furthers our understanding of the performance trade-offs when choosing TCP over RPL in IPv6-based LLNs.

This article describes a laboratory research on stabilizing tropical peat using ordinary Portland cement (OPC) as a binding agent, and polypropylene and steel fibres as chemically inert additives. California bearing ratio (CBR) and unconfined compressive strength (UCS) tests were carried out to evaluate the increase in the strength of the stabilized samples compacted at their optimum moisture contents and air cured for up to 90 days. The results show that the UCS values of stabilized peat samples increased by as high as 748.8% by using OPC (5%), polypropylene fibres (0.15%), and steel fibres (2%). The CBR values of the samples stabilized with OPC (5%), polypropylene fibres (0.15%), and steel fibres (4%) showed an increase of as high as 122.7%. The stabilized samples showed a shrinkage in volume upon air curing and this shrinkage was measured by an index called, volume shrinkage index (VSI). The highest VSI recorded was 36.19% for peat without any additives; and the minimum was 0% for the sample containing 30% OPC, 0.15% polypropylene fibres and 2% steel fibres. The technique of stabilizing peat with OPC, polypropylene and fibres, coupled with air curing, appears to be cost-effective compared with other frequently used techniques.

Medical ethics has been integrated into the curriculum for medical education in Korea for over 30 years now. There have been many attempts to establish standards for the educational objectives and curriculum, including establishing learning outcomes and publishing medical ethics textbooks in Korean. However, this task is not easy for several reasons: the interdisciplinary nature of the subject, educators' lack of experience, and the lack of a consensus on the criteria that would be effective educational goals. In this article, the author explores (1) the need for reflection on the education itself, (2) two perspectives of medical ethics education, (3) critical perspectives on the effectiveness of the current medical ethics education, and (4) the variety of modalities of medical ethics education. Further, the author proposes a way to teach medical ethics in Korea. The contents and means are closely related to the question of philosophy of medical education: "Should professional ethics education be 'realistic' or 'idealistic'?" Ethics requires educators to be open to new learning experiences and to ethical development. Medical Ethics education should be relevant to everyday clinical experiences and, at the same time provide students and educators to critically review their ethical perspective through reflections.

Arsenic trioxide is one of the 'tooth pulp devitalizing agents' used through the dental history when anaesthesia was not available. But owing to its capacity to kill cells in surrounding tissues, the use of arsenic trioxide in vital pulpotomy has been reduced. Arsenic trioxide can cause necrosis of gingiva, bone which can cause osteomyelitis of the jaws. But some dentists still continue to use arsenic trioxide in their endodontic practices. The purpose of this article is to present arsenic trioxide induced osteomyelitis on maxilla and treatment process.
