  • Objectives : JiaoTeng-Yuan(교등원) is said to be a prescription for preservation of health in $\ulcorner$HuaTuo.ZhongZangJing (화타.중장경)$\lrcorner$. It is known to have the effect of Bu-Shen (보신: strengthening kidney) and Yi-Shou (익수: prolonging the span of one's life). This study investigates whether JTY is effective on inhibition of oxidation stress. Methods : Sprague-Dawley rats (12-week-old, weight $300{\pm}20g$) were divided into 3 groups. The normal group (n=8) was injected with PBS (1ml/body, s.c) subcutaneously behind the neck. The control group (n=8) was injected with D-galactose (50mg/kg, 1ml PBS/body, s.c) to induce pathological animals. The JTY group was injected with the same treatment as the control group, and fed containing JTY (10%). All groups were treated 1 time per day for 6 weeks. After the rats were sacrificed anti-oxidant enzyme (SOD, CAT, G-px) activity, GSH quantity of RBC and tissue (heart, liver and kidney), and plasma Vit-C quantity were examined. Also, the MDA levels of liver and kidney, lipofuscin of heart and endurance of erythrocyte membrane were measured. Results : In the JTY group, RBC's SOD activity decline was halted by 21 % of the normal level, compared to the control group, G-px activity (unit/g of Hb) increased significantly, compared to the normal group, and the level of Vit-C in plasma increased by 16%. Heart's SOD activity was kept at the same level as that of the normal group; and CAT activity decline was halted by 26%. Kidney's CAT and G-px activities were kept at the same level as that shown in the normal group, implying the existence of a halting effect. Liver also showed a slight halting effect against the decline of anti-oxidant ability, but the effect was not significant (${\alpha}=0.05$). A comparison between the levels of peroxide in SD rats showed that the level of TBARS in plasma increased significantly in the control group and that it was normal in the JTY group. The livers in the JTY group, compared to those in the control group, showed 36% halting effect of the normal level while their kidney's indicated the level significantly lower than the normal level. Heart's lipofuscin increased significantly in the control group, but was alike in both the JTY and the normal groups. Endurance of erythrocyte membrane (%) decreased significantly in the control group while it was kept at the similar level in both the JTY and the normal groups, indicating the halting effect. Conclusions : This study suggests that JTY is effective to defend oxidation stress caused by D-galactose in the animals. It showed that the anti-oxidant ability was maintained and strengthened. On the other hand, it reduced the level of peroxide in animals. In sum, JTY appeared to have the equilibrium normal physiological function in SD rat.

  • 마는 다양한 생리활성물질을 포함하여 항 당뇨, 혈당강화 및 콜레스테롤 저하 효과가 있는 것으로 보고된다. 본 연구에서는 마를 각각 진공 알코올 전 처리하여 포장한 경우와, 진공 포장 후 블랜칭 처리 시 갈변(PPO 활성) 및 품질변화에 미치는 영향을 조사하였다. 평가는 색도변화, 경도변화, 미생물 총 균수를 측정하였고, 블랜칭 처리구의 경우 갈변현상과의 유의성을 알아보기 위해 PPO 활성도 변화를 추가적으로 측정하였다. 실험 결과, 알코올 전 처리구의 경우 농도에 따른 색의 변화가 유의적인 차이가 있었으며, 5% 알코올 처리가 대조구나 10% 처리보다 갈변억제 효과가 있었다. 하지만 블랜칭 처리구의 경우 유의적인 색의 변화가 나타나지 않았다. 또한 PPO 활성도가 1분 블랜칭의 경우 대조구 대비 50% 이하로, 5분 처리구는 85%의 활성이 감소된 것으로 보아 갈변억제 효과가 있었음을 알 수 있었다. 경도의 경우 두 실험구 모두 감소하는 것으로 나타났으며, 특히 1분 이상 블랜칭 처리한 처리구의 경우 대조구에 비하여 10 N 이상의 경도가 저하되는 것으로 나타났다. 미생물은 두 처리방법 모두 감소 추세를 보였으며, 알코올 전 처리구의 경우 알코올의 농도에 따라 감소 추세를 보였고 블랜칭 처리구의 경우 처리 시간에 따른 감소 추세를 보였다.

  • 제품판매를 촉진하고 기업이윤의 극대화를 모색하는 기업논리로만 좋은 기업이미지를 형성하는 것은 불가능하다. 좋은 기업이미지 형성을 위하여 형성하는 것은 불가능하다. 좋은 기업이미지 형성을 위하여 기업활동을 통하여 효과적인 마케팅 이미지를 형성해야 하고 올바른 사회적 행동을 통하여 바람직한 사회적 이미지를 형성해야 하며, 문화적예술에 대한 투자, 보건, 교육, 사회적 복지프로그램등에 지원활동으로 사회적 신뢰를 획득해야 한다. 기업은 의도한 바대로의 기업이 미지를 대중들이 가질 수 있게 노력하지만 대중은 여러 정보들을 토대로 주관적으로 기업이미지를 지니게 된다. 기업이미지 형성 자체가 대중의 이성적이기 보다는 감성적인 주관에 의한 것이므로 감성적 접근과 감정적 설듯이 더욱 효과적인 요소가 된다. 유머효과는 기존의 연구를 통해 주의집중, 기억, 설득의 매우 강력한 수단이 된다는 것은 입증된 바 있다. 현대의 가장 인기잇는 광고의 대부분이 유머광고이고, 설문을 통하여 20대 대학생의 절대다수가 유머광고를 선호하고 있고 좋은 기업이미지를 위하여 유머러스한 제품광고를 통한 기업이미지 제고효과, 기업이미지 광고에 유머효과의 사용 그리고 기타 커뮤니케이션 활동에 유머효과를 사용하는 것에 대다수가 긍정적인 의견을 가지고 있다는 것을 확인할 수 있었다. 좋은 기업이미지 형성을 위해 유머효과는 친근함을 유도해 내고, 광고의 역기능적인 면을 최소화하고 정신적 즐거움을 주면서 설득효과를 가진다. 유머효과는 기업실체를 반영한 좋은 기업이미지 형성에 효과적일 뿐만 아니라 광고 커뮤니케이션의 아이디어 개발 근처로 활용할 수 잇다. 유머를 웃음을 유발하는 단순한 수단이라기 보다 인간에 대한 깊은 관조와 이해를 바탕으로한 휴머니즘의 또다른 표현이라고 본다면 바람직한 기업이미지와 연관한 연구는 의미가 있다고 할 수 있다.

  • The purpose of this study is to analyze hygiene education contents of elementary schools in Korea, USA, Japan and compare this and to provide with basic material present improvement method when hygiene education contents of elementary schools in Korea are organized. For this purpose the problems as following are selected centering on the hygiene education contents of the 7th education process in Korea and Japan and the hygiene text of public school in California, USA. First, this study tries to analyze the composition classified by 12 guidance contents each grade of hygiene education contents of elementary schools in Korea, USA, and Japan. Second, this study tries to analyze the composition classified by fields(physical, mental, social) of hygiene education contents of elementary schools in Korea, USA, and japan. As a result of the analysis and comparison on the matters stated above, the conclusion as following was gotten. First, as a result of searching the hygiene education contents system of elementary schools in Korea, USA, and Japan classified by 12 guidance contents each grade, the subjects which have good contents composition classified by class step by step were safe life and disease prevention. And the subjects such as growth development and health, physical fitness, drug use and health were weak and the parts such as consumer health and the careers concerned with are not dealt in the present education process of Korea at all. Second, as a result of analyzing the composition classified by fields of hygiene education contents of elementary schools in Korea, USA, Japan, all the three countries put great on physical part. And there are 57 units about mental part in USA, 27 units in Japan, only 17 units in Korea. And this fact reveals that there was lack of understanding about the need of mental part in Korea. This study tries to suggest improvement method as following through the study results stated above. First, as it is grasped in the analysis classified by guidance part of hygiene education contents, community and environment preservation, physical aptitude and stress management are to be emphasized more strongly and about the parts like consumer health and the persons concerned with hygiene new education programs as contents satisfying the need of age are to be inserted or complemented Second, because the hygiene education contents in Korea are still lack in comparing contents of mental parts compared with those of the two countries, the contents proper to the level and the requirement of learners to each grade are to be developed and complemented. Third, hygiene education units which were reduced in the 7th curriculum in Korea are lack compared with those in the two countries. Therefore, it is necessary that teachers should recognize the need of hygiene education so that the hygiene education can be separated and be taught out regularly.

  • Kochujang, a fermented hot pepper soybean paste, is a spicy condiment mixed with red pepper, boiled rice and mold fermented soybean (as koji) which is then fermented for several months. It has unique taste of hot, sweet, salty and savory flavor by all mixed ingredients by fermentation, and is one of most famous Korean traditional foods. The scale of the kochujang industry is about 200 billion won in Korea, and 7.8 million dollars and 4,500 tons in exports. Although it is still not a large part of the food industry in Korea, the scale of soy products will increase because it is a major subsidiary food in our dietary life and has grown from a homemade to a mass produced product. Kochujang has the largest market in the scale of sales among fermented soybean products and has merit because of its domestic base and its ability to grow to an international market due to its unique fermented taste. In order to make kochujang an international food, it Is necessary to study the scientific development of kochujang and the diversity of products using kochujang that are fitted to the taste of people around the world. In addition, participation in various exhibitions and food fairs supported by the government should help to promote kochujang throughout the world. In addition, these should be actively supported by the related businesses. Red pepper, a major ingredient in kochujang, has been widely studied and shown to have a positive effect on the reduction of fat, on the strengthening of the immune system, and on active biological functions. A fermented spice like kochujang has been shown to be beneficial for the body due to the process of fermentation rather than from the red pepper itself. If we prove the various biological functions of kochujang with a particular taste and flavor, it will energize a new market. It is necessary for business to make a continuous effort supported fly the scientific world and by government policy, in order to introduce this traditional food to the world. In the present day, the kochujang market is now on a firm basis and has been activated in the field of its study. Now, it is possible to achieve the birth of a secondary international market by concentrating on these efforts.

  • Standard therapy for advanced head and neck cancer consists of a combination of surgery and radiation. However, survival of this patient population has not improved during the past 20 years. Many different multimodality treatment schedules have been proposed, and chemotherapy is often used with the intent of organ preservation. The present study was intended to establish the efficacy of concomitant chemoradiation with a single agent carboplatin in advanced head and neck cancers.The objectives were to investigate the feasibility of concomitant administration of carboplatin, monitor acute toxicity during radiotherapy, and determine subacute side effects, such as wound healing following surgery after chemoradiotherapy. A prospective study was conducted wherein a total of 40 patients with stage III and IV squamous cell carcinomas of oral cavity, oropharynx, hypopharynx and larynx were enrolled. All patients were treated with external beam radiotherapy and weekly carboplatin area under curve (AUC of 5). Radiotherapy was given in single daily fractions of 1.8-2 grays (Gy) to a total dose of 66-72 Gy. Salvage surgery was performed for any residual or recurrent locoregional disease. Neck dissection was recommended for all patients with neck disease showing less than a complete response after chemoradiation. A total of 40 patients were enrolled of whom 32 were males and 8 were females. Highest incidence of cancer was seen in the 5th-6th decades of life with a median age of 47.7 years. Oropharyngeal tumours constituted a maximum of 21 patients followed by hypopharynx in 10, larynx in 7 and oral cavity in 2. 80% of the patients had a neck node on presentation of which 40% had N2-N3 nodal status. TNM staging revealed that 58% of patients were in stage III and 43% in stage IV. Evaluation of acute toxicity revealed that 50% had grade II mucositis, 25% grade III mucositis, 2.5% grade IV mucositis. 50% of patients had grade I skin reactions, 65% of patients had grade I thrombocytopenia, and 24% of patients had grade I anaemia. After completion of treatment 65% of patients had complete response at the primary and regional sites, and 35% of patients had a partial response of whom 23% underwent neck dissection and 5% of them underwent salvage surgery at the primary site. At the end of one year there were six deaths and four recurrences and 70% were free of disease. Concurrent chemoradiation with carboplatin provided good locoregional control for locally advanced head and neck cancers. This regimen, although toxic, is tolerable with appropriate supportive intervention. Primary site conservation is possible in many patients. Chemoradiotherapy appears to have an emerging role in the primary management of head and neck cancers.
