With rapid economic development, the emphasis of the public health movement in Korea has shifted towards addressing the burden of chronic disease. With this shift in direction comes a greater focus on health behaviour and the need for planning models to assist in lifestyle modification programs. The Health Belief Model (HBM), which originated in the US, has generated more research than any other theoretical approach to describe and predict the health behaviour of individuals. In recent years it has been applied in many different cultures and modifications have been suggested to accommodate different cultures. Given the centrality of language and culture, any attempts to use models of health behaviour developed in a different culture, must be studied and tested for local applicability. The paper reviews the applicability and suitability of the HBM in Korea, in the context of the Korean language and culture. The HBM has been used in Korea for almost three decades. The predictability of the HBM has varied in Korean studies as in other cultures. Overall, this literature review indicates that the HBM has been found applicable in predicting health and illness behaviours by Korean people. However if the HBM is used in a Korean context, the acquisition of health knowledge is an important consideration. Most new knowledge in the health sciences is originally published in English and less frequently in another foreign language. Most health knowledge in Korea is acquired through the media or from health professionals and its acquisition often involves translation from the original. The selection of articles for translation and the accuracy of translation into language acceptable in the Korean culture become important determinants of health knowledge. As such translation becomes an important part of the context of the HBM. In this paper modifications to the HBM are suggested to accommodate the issues of language and knowledge in Korea.

Sparassis latifolia is called "Cauliflower Mushroom" and is known as an edible mushroom that has high content of ${\beta}$-glucan. Recently, artificial cultivation of S. latifolia has been done by bottle, plastic bag and wood cultivation in Korea. However it is not widely used because there are low incubation ratio and yield. For the high efficiency of production, we aim to find the superior strains and media for better mycelial and fruit body growth. First, we analyzed the genetic relationship among 31 strains and divided five groups with three kinds of URP primers. And then ten strains were selected from five groups based on the experiment of mycelial growth. The suitability of media for mycelial growth was different according to media type. The suitable solid and liquid media for mycelial growth of S. latifolia isolates were PDA and M2, respectively. In addition, with regard to C/N ratio, the mycelial growth increased even until C/N 160. Second, we investigated the production of fruitbody of the strains by plastic bag cultivation. The substrate was mixed with larch sawdust, corn flour, and wheat flour (8:1:1, v/v). Moisture content of substrate was controlled by about 60% with 10% molasses solution. Out of 31 strains, 19 strains formed primordia. The eight strains produced more than 140g/1kg in fresh weight. Third, molasses culture media was selected for the mycelial growth. And molasses suitable sugar content and input aeration were around 8Brix% and 0.3~0.6vvm, respectively. The longer the incubation period is, the more dried weight of mycelia increased, but medium volume decreased. Therefore, the best incubation period was 9 to 11 days depending on strains. In the future, research project entitled development of culture system and new variety for stable production of S. latifolia will be considered as a new item.

Clothes for a 3 to 6 year-old toddler should be made in consideration of their behavioral characteristics since it is when the physical ability of toddlers has rapidly developed and their social, emotional, and cognitive development are increasingly active. Indoor clothes are the item that consumers prefer because they provide the function of outside underwear when functioning as outerwear when indoors that is used frequently for toddlers. We analyzed the wearing condition and the uncomfortable aspects of toddler's clothes worn indoors through consumer surveys of toddler wear. This study gathers data for the development of indoor clothing that is useful for 3-6 year old toddlers. Consumer surveys indicate that the clothes most worn indoors were underwear (69.4%). The most important aspect in the selection of indoor clothes was the suitability for activities (29%). The preferred colors for indoor clothes were found to be pastel-tone colors (66%). Regarding the uncomfortable aspects of indoor clothes, knees of the clothes (36.8%) have the most naps and the breast of the clothes (37.8%) dirty quickly. Knee parts (35.4%) become worn easily; in addition, the material for the knee area is likely to have naps and require special functions. In conclusion, designing toddler clothing requires elaborated design techniques that consider the characteristics of the subject group and reduce inconveniences. This study will serve as preliminary data to develop ultimate products that have the functionality to meet gender behavior characteristics and the aesthetics for toddlers 3 to 6 years of age.

Background: This study was conducted to compare the physicochemical properties of 12 different cultivars of Rehmannia glutinosa, a plant used in Korean traditional herbal medicine. Method and Results: We investigated the following 12 cultivars of R. glutinosa; Jihwang1, Goryeo, Daegyung, Gogang, Togang, Dagang, Wongang, Yeongang, Hwanggang, Dahwang, Segang and Chunggang. We measured water content, chromaticity, hardness, active components levels, and antioxidant activity. Our results showed that Togang has the lowest water content and the highest yield. The catalpol content was the highest in Togang (40.50 mg/g) and the lowest in Chunggang (22.17 mg/g). The aucubin content was the highest in Hwanggang (0.28 mg/g). Chunggang had the lowest aucubin content, but the highest level of verbascoside. Total flavonoid and total polyphenol were the highest in Daegyung and Chunggang, respectively. There was a strong correlation between the total flavonoid and total polyphenol (r = 0.89) content. Conclusions: There were significant differences in physicochemical properties among 12 cultivars. These properties will affect suitability for processing and final product quality. We therefore suggest the selection of appropriate cultivars for different uses.

Managed Aquifer Recharge (MAR) in the form of Aquifer Storage and Recovery (ASR) systems are being applied for numerous water augmentation projects both in developed and developing countries. Given the onset of Climate Change and its influence on weather patterns and land use, it has been acknowledged the utilization of this technology will be ever increasing. This technique like all others does have its drawbacks or disadvantages, whereby to overcome these drawbacks or disadvantages it is recommended that logical planning process be followed. In this study, we developed a decision framework known as "Decision framework for the planning, designing, construction/testing and implementation of subsurface water storage system" to further standardize the planning and design process of subsurface water storage system to increase the probability of having a successful ASR/ASTR project. The formulation of this framework was based on earlier frameworks, guidelines, published papers and technical reports which were compiled into a data collection database. The database of which consider both qualitative and quantitative aspect for example recharge objectives, site location, water chemistry of the native, source and recovered water, aquifer characteristics(hydraulic conductivity, transmissivity, porosity), injection/pumping rate, ecological constraints, societal restrictions, regulatory restrictions etc. The assimilation of these factors into a singular framework will benefit the broad spectrum of stakeholder as it maps the chronological order under which ASR project should be undertaken highlighting at each stage the feasibility of the project. The final stage of which should result in fully operational ASR system. The framework was applied to two case studies and through the application of a modified ASR site selection suitability index (Brown et al., 2005) a score was derived to identify the performance of each site. A high score of which meant a maximize chance of success given the reduce presence of project constraints.

The purpose of this study was to investigate the wearing & fit of ready-made and online custom dress shirts by surveying middle-aged men aged 40-54 years in order to collect information necessary for making good fit dress shirts. Also, we analyzed whether there were significant differences in the actual wearing of dress shirts according to the stature of middle-aged men. The stature was classified according to KS K 0050 as $R(157{\leq}x<170)$ and $T(170{\leq}x<182)$. The 23 questionnaire items were divided into three categories: 'General purchasing behavior and wearing', 'Fit satisfaction of ready-made dress shirts' and 'Wearing and fit satisfaction of online custom dress shirts'. Through the results of the study, we could understand the actual wearing condition of ready-made and online custom dress shirts. Also, differences in stature groups were found. The significant differences according to the stature groups were found in the interest in fashion, the purchase criteria, the limitation of the shirt size selection due to stature and body shape, shirt size satisfaction, repair experience, dissatisfaction with purchase and the experience of purchasing online custom dress shirts. Suggestions should be made to improve dissatisfaction with stature groups in the ready-made dress shirts. In addition, the study confirmed the consumer demand for the online custom dress shirts. In order to activate the online custom market, the online custom dress shirts company needs to reduce consumer dissatisfaction and improve size suitability.
