This study was conducted to analyze the current management status of green tea processors in two regions (Hadong-gun and Boseong-gun) in Korea and to suggest directions for the development of the green tea industry based on an understanding their difficulties in management. This study showed that the number of green tea farms and the cultivation area had decreased, while the average unit sales price of green tea in Boseong-gun was approximately three times higher than that in Hadong-gun. Also, this study found that Hadong-gun mainly provided green tea products to wholesalers, whereas Boseong-gun sold it directly to the local retail stores targeting tourists, and this results in generating relatively higher unit prices. Meanwhile, we discovered that both regions had difficulties in management which were caused by the demand for low delivery unit costs from large corporations and small food companies. Therefore, in order to develop the green tea industry in both regions, the size of green tea fields and the scenery satisfaction should be improved to draw more tourists and boost tourists' intention to revisit. In addition, it is necessary to enhance guidance and accessibility of related tourist sites, to expand green tea experience activities, and to improve product satisfaction by developing various goods. By inducing more tourists in these ways, it could change the sales type of green tea from wholesale to retail and help activate the management of green tea processors.

Deer Antler has been known for its traditional oriental medicinal properties and has been widely used to promote growth, boost immune function, treat blood loss and chronic joint pain. Recent study showed imported (New Zealand) Deer Antler was beneficial in reducing the side effects of cancer treatments. However, there was no intervention study conducted on the effect of Korean Deer Antler on reducing the oxidative stress to patients with diabetes. One of the sensitive ways to measure endogenous oxidative stress is by measuring cellular DNA damage using single cell gel electrophoresis (COMET assay). This study was conducted to investigate the possible beneficial effect of commercial Deer Antler drink (provided by Chung-yang Deer Farm) on lymphocyte DNA damage and blood glucose of diabetic patients. Ten patients (4 men, 6 women) participated in the study and consumed 2 pouches of Deer Antler drink every day for 20 days. Blood was collected on the morning before and after the intervention for lymphocyte isolation and blood glucose analysis. Both systolic and diastolic blood pressure showed a tendency to decrease but did not reach statistical significance after the trial. Blood glucose level was not affected by the supplementation. After the intervention, over 50% reduction were noted in the cellular DNA damage, expressed as tail length (TL) and tail moment (TM: tail length ${\times}$ percent tail DNA) . Although we did not obtain beneficial effect on lowering blood glucose levels in the patients, this results suggest that Deer Antler may initially act in protecting endogenous DNA damage in short-term experiment.
21st century is the Age of Culture, and a period that is represented by symbolism and imagery. This is no exception for the countries that want to enhance their image in the international community. In order for a country to improve its brand, it has to select a representative emblem, symbols and cultural items. The usual suspects for this are its name, flag, and anthem. Each of these items can elicit different types of symbolism. It can also be used to differentiate the country from others; however, these are not the only sources of symbolism at the country's disposal. Other popular tools include cultural heritage, both tangible and intangible, climate, natural environment, and its national character. A country can use these items to associate itself with certain images. The purpose of this study is to find an objective way to effectively boost Korea's brand. This will be done by comparing and contrasting the ways countries including Korea have used their national emblems to enhance their image. Data from each of the countries were collected and analyzed. The results of this study will become empirical evidence in researches aimed to develop fashion designs that use Korea's national emblem as its motif in order to improve its national brand Countries that were used for this research were United States, United Kingdom, Japan, France and Korea, and they were chosen because their national brand rated highly. The items selected for the analysis were scarves and neckties. This was because, compared to other fashion items, it was easier to sort out scarves and neckties that used motifs of national emblems as well as these two items having the highest usage rate of this type of motif. Group of experts looked through a combined total of 370 scarves and ties and they analyzed the following factors in the design: type of motifs, frequency, use of color, methods of expression and images.
Background: The standard radiotherapy (RT) fractionation practiced in India and worldwide is 50Gy in 25 fractions over 5 weeks to the chest wall or whole breast followed by tumour bed boost in case of breast conservation (BCS). A body of validated data exists regarding hypofractionation in breast cancer. We here report initial results for 135 patients treated at our center with the START-B type of fractionation. Materials and Methods: From May 2011 till July 2012, women with all stages of breast cancer (excluding metastatic), who had undergone BCS or mastectomy were planned for 40Gy in 15 fractions over 3weeks to chest wall/whole breast and supraclavicular fossa (where indicated) followed by tumour bed boost in BCS patients. Planning was done using Casebow's technique. The primary end point was to assess the acute toxicity and the cosmetic outcomes. Using cosmetic scales; patients were assessed during radiotherapy and at subsequent follow up visits with the radiation oncologist. Results: Of the 135 patients, 62 had undergone BCS and 73 mastectomy. Median age of the population was 52 years. Some 80% were T1&T2 tumours in BCS whereas most patients in mastectomy group were T3&T4 tumours (60%). 45% were node negative in BCS group whilst it was 23% in the mastectomy group. Average NPI scores were 3.9 and 4.9, respectively. Most frequently reported histopathology report was infiltrating ductal carcinoma (87%), grade III being most common (58%), and 69% were ER positive tumours, and 30% were Her 2 Neu positive. Triple negative tumours accounted for 13% and their mean age was young (43 yrs.) The maximum acute skin toxicity at the end of treatment was Grade 1 in 94% of the mastectomy grouppatients and 71% in BCS patients. Grade 2 toxicity was 6% in mast group and 23% in BCS group. Grade 3 was 6% in BCS group, no grade 3 toxicity in mastectomy patients and there was no grade 4 skin toxicity in any case. Post RT at 1 month; 39% of BCS patients had persisting Grade I skin reaction which was only 2% in mastectomy patients. At 3 months post RT, 18% patients had persisting hyperpigmentation. At 6 months 8% patients had persisting erythema in the BCS group only. Some 3% BCS and 8% mastectomy patients had lymph edema till the date of evaluation. Cosmetic outcome in BCS patients remained good to excellent 6 months post surgery and radiotherapy. 1 patient of BCS and 3 patients of mast had developed metastatic disease at the time of evaluation. Conclusions: Hypofractionated RT is well tolerated in Indian population with reduced acute skin toxicity and good cosmetic outcome. Regimens such as these should be encouraged in other centers to increase machine output time. The study is on-going to assess long term results.
The purpose of this study was to develop the entity theory on the recovering process from gambling addiction. This study focused on "What is the process of getting out of the pit of gambling addiction?" based on grounded theory methodology suggested by Strauss and Corbin(1990). The subjects of this study were 7 male gambling addicts living in Jeonbuk area. As the result of this study, a total of 97 concepts were drawn, which were classified into 28 subcategories and 16 superordinate categories. The results of analyzing the categories by paradigm showed that in the process of overcoming gambling addiction, the casual condition was 'Being cut off money; 'Losing the will', and the contextual condition corresponding to this phenomenon was 'Shame', 'Repent', and 'Wanting to die'. The core phenomenon was 'Giving up the dream of hitting the jackpot'. The intervening condition to boost this core phenomenon was 'Being helped by friends', 'Being supported by the police', 'Being led by the family', and 'Showing the willpower'. The action/interaction strategies were identified as 'Cutting off the flow of funds', 'Overcoming the temptation of gambling', and 'Diverting attention to other things', ending up 'Being conscious of family', 'Growing up', and 'Being free'. The core concept in the process of overcoming the gambling addiction was revealed as 'Being free by giving up the dream of hitting the jackpot'. The process of getting over the gambling addiction was 'The dream of hitting the jackpot being shattered', 'Giving up the dream of hitting the jackpot', 'Getting out of it', and 'Being free'. The study participants were classified into four types; 'Challenging type', 'Enjoying type', 'Showing off type', and 'Obsessive type'. This study was expected to have significance in establishing the first theory in Korea on the recovering process of gambling addict.
The purpose of this research is to find out whether children's self-efficacy can be improved by sensory activities devised to encourage spirituality. The survey involved 36 children aged 4 to 5. To measure the subjects' self-efficacy, Jeon Inok(1996)'s tool was used. The 18 members of the experimental group attended a program which was dedicated to promoting spirituality by using sensory activities. The program was administered three times a week for four weeks, totaling 12 sessions, each of which contained a type of activity and lasted about fifty minutes. To the 18 members of the control group, the standard child care curriculum was applied. The levels of the subjects' self-efficacy were measured twice, both in the same way, before and after the children participated in the program. The finding reveals that the program which was designed to boost children's spirituality through sensory activities has positive effect on children's self-efficiency - cognitively, socially, emotionally, and physically. The self-efficiency level in the experimental group significantly increased by t=7.17(df=34, p<.001) compared to the control group. So, it can be said that the program dedicated to improving spirituality using sensory activities is more effective than the standard child care curriculum.
Purpose: To evaluate acute toxicity in nasopharyngeal cancer (NPC) patients treated with intensity modulated radiotherapy (IMRT)/volumetric modulated arc therapy (VMAT) with or without cisplatin-based chemotherapy. Materials and Methods: A total of 45 newly diagnosed, histologically proven non-metastatic NPC patients treated with IMRT between May 2010 and December 2012, were evaluated retrospectively, 37 planned with Eclipse and 8 with Prowess Panther treatment planning system. The doses to the planning target volumes of primary tumor and involved lymph nodes, high risk region, and uninvolved regional nodal areas were 70 Gy, 60 Gy, and 54 Gy respectively and delivered simultaneously over 33 fractions to 39 patients. Another 6 patients irradiated with sequential boost technique. Some 84.4% of patients received chemotherapy. Acute toxicities were graded according to the Radiation Therapy Oncology Group scoring criteria and Common Terminology Criteria for Adverse Events (CTCAE) for chemotherapy side effects. Results: Median age was 43 years (14-79) and all patients were WHO type II. Grade 1 mucositis and dysphagia were observed in 17 (37.8%), and 10 (22.2%) patients, respectively. The incidence of acute grade 2 mucositis and dysphagia was 55.6% and 68.9%, respectively. The most common chemoradiotherapy related acute toxicities were nausea, leucopenia and thrombocytopenia. Grade 3 toxicity was detected in 13 (28.8%) cases. No grade 4 toxicity was occurred. Mean weight loss was 9%. None of the patients required the insertion of percutaneous endoscopic gastrostomy for nutritional support. Radiation therapy was completed without interruption in all patients. Conclusions: IMRT is a safe and effective treatment modality, and well tolerated by patients in the treatment of nasopharyngeal carcinoma. No unexpected side effects were observed.
With progress in emerging new media technology and associated device, there is growing interest in a new type of contents in the filed of children education. In this research, we developed a edutainment content for enhancing sociability and visual perception of children exploiting kinect. Recreating what is visually perceived with physical movement is adopted to develop visual perception. It is also designed such that one's sociability can be enhanced through experiencing natural physical contact and collaboration while interacting with the developed content. The prototype of the content was created through development of character to boost interest, a short animation for storytelling, and interactive programming. In the second pilot test which was done with the content improved through the first pilot test, it was observed that children easily played with it and actively participated in experiencing it. From this observation, it is expected that the developed content may work as a promising edutainment content which fosters children to enhance visual perception and sociability through natural interaction.

Purpose: The purpose of this study is to compare the dosimetry of electron beam (EB) plans and three-dimensional helical tomotherapy (3DHT) plans for the patients with left-sided breast cancer, who underwent breast conserving surgery. Materials and Methods: We selected total of 15 patients based on the location of tumor, as following subsite: subareolar, upper outer, upper inner, lower lateral, and lower medial quadrants. The clinical target volume (CTV) was defined as the area of architectural distortion surrounded by surgical clip plus 1 cm margin. The conformity index (CI), homogeneity index (HI), quality of coverage (QC) and dose-volume parameters for the CTV, and organ at risk (OAR) were calculated. The following treatment techniques were assessed: single conformal EB plans; 3DHT plans with directional block of left anterior descending artery (LAD); and 3DHT plans with complete block of LAD. Results: 3DHT plans, regardless of type of LAD block, showed significantly better CI, HI, and QC for the CTVs, compared with the EB plans. However, 3DHT plans showed increase in the $V_{1Gy}$ at skin, left lung, and left breast. In terms of LAD, 3DHT plans with complete block of LAD showed extremely low dose, while dose increase in other OARs were observed, when compared with other plans. EB plans showed the worst conformity at upper outer quadrants of tumor bed site. Conclusion: 3DHT plans offer more favorable dose distributions to LAD, as well as improved target coverage in comparison with EB plans.

Exhaust gas recirculation (EGR) is an emission control technology allowing significant NOx emission reduction from light-and heavy duty diesel engines. The future EGR type, dual loop EGR, combining features of high pressure loop EGR and low pressure loop EGR, was developed and optimized by using a commercial engine simulation program, GT-POWER. Some variables were selected to control dual loop EGR system such as VGT (Variable Geometry Turbocharger)performance, especially turbo speed, flap valve opening diameter at the exhaust tail pipe, and EGR valve opening diameter. Applying the dual loop EGR system in the light-duty diesel engine might cause some problems, such as decrease of engine performance and increase of brake specific fuel consumption (BSFC). So proper EGR rate (or mass flow) control would be needed because there are trade-offs of two types of the EGR (HPL and LPL) features. In this study, a diesel engine under dual loop EGR system was optimized by using design of experiment (DoE). Some dominant variables were determined which had effects on torque, BSFC, NOx, and EGR rate. As a result, optimization was performed to compensate the torque and BSFC by controlling start of injection (SOI), injection mass and EGR valves, etc.
