Korea Ginseng Corporation is a global ginseng company, owning one of the most leading brands in Korea, CheongKwanJang. Although Korea Ginseng Corporation was an undoubted market leader in the red ginseng market, it faced a new challenge in 2012 due to the changes in market environment. In order to keep its market leadership in a saturated and competitive market, the company decided to extend its product lines alongside the launches of new brands. In this article, the authors demonstrate the development process of the company's brand portfolio strategy to reveal how the company turned CheongKwanJang into a mega-brand. Also, this paper explores the impact of CheongKwanJang's reputation on new brands, thereby illustrating how the company successfully managed to introduce new products outside of the red ginseng category, ranging from organic food to a pet food market.

We studied the electrical, optical and structural properties of microcrystalline silicon thin films prepared by a new chemical vapour deposition technique, called filament assisted(FA)-CVD. The microcrystalline silicon is sucessfully deposited when the hydrogen dilution ratio exceeds 30. The Raman peak at 520 cm-1 and the X-ray diffraction peak at 27.7\ulcorner0.2\ulcornerbecome sharper with increasing hydrogen dilution ratio. We obtain high quality microcrystalline Si by FA-CVD with optical gap of \ulcorner2.2eV and hydrogen content of \ulcorner3 at %.

Particular matter is steadily increasing due to environmental factors at domestic and abroad such as industry and economy. Recently, the exposure particular matters has been reported to increase the risk not only for morbidity and mortality, but also for diseases of the respiratory system, cardiovascular system and central nervous system/neuropsychiatric disorder. Although the causes of neuropsychiatric diseases are genetic and environmental factors, it is necessary to pay more attention to environmental factors in terms of prevention. We mainly describe environmental factors that affect neuropsychiatric disorders, mainly on particular matter, which is one of harmful environmental substances. In the current study, we reviewed evidence for the presence of particular matter or particular matter related harmful air pollutants-O₃, SO₂, NO₂/NOx, traffic related air pollution, that may represent risk factors for the development of neuropsychiatric disorder.

Risk assessment considers the situations and characteristics of the exposure environment and host. Various physiological variables of the human body reflects the characteristics of the population that can directly influence risk exposure. Therefore, identification of exposure factors based on the Korean population is required for appropriate risk assessment. It is expected that a handbook about general exposure factors will be used by professionals in many fields as well as the risk assessors of the health department. The process of developing the exposure factors handbook for the Korean population will be introduced in this article, with a specific focus on the general exposure factors including life expectancy, body weight, surface area, inhalation rates, amount of water intake, and soil ingestion targeting the Korean population. The researchers used national databases including the Life Table and the 2005 Time Use Survey from the National Statistical Office. The anthropometric study of size in Korea used the resources provided by the Korean Agency for Technology and Standards. In addition, direct measurement and questionnaire surveys of representative samples were performed to calculate the inhalation rate, drinking water intake, and soil ingestion.

Aging society and aged society are determined by the component ratio of the elderly to the whole population; aging society is defined as a society whose ratio of the elderly population is less than 7%, and it is called aged society when the ratio is over 14%. Korea's aging process is so fast and unprecedented over the world according to many statistical data and investigations. The purpose of this study was to provide guidance and basic data to educate the elderly for the proper use of medication and health functional food. This study was carried out on 80 subjects of age 65 or older in Cheong Jusi in Choogncheongbuk-do. They answered questionnaire that was prepared for this study. The data were collected from August 4, 2008 to August 18, 2008. The collected data were analyzed by using the SPSS 12.0OK (for window) program and Microsoft EXCEL. The following is a summary of the results of this study. First, in the aspect of purchasing, the majority of respondents bought OTC drugs and health functional food for health and illness prevention. Purchasing places of drugs were diverse. Second, in the aspect of taking drugs, the older answerers were, the higher the number of drugs being taken was. Third, in the aspect of proper storage of drugs, most respondents have no specific spaces. Finally, regarding recognition of drug abuse and disposal, most people have little awareness or have no idea.

Objectives: This study was conducted to examine the relationship between crude oil exposure and physical symptoms among residents participating in clean-up work associated with the Hebei Spirit oil spill, 2007 in Korea. Methods: A total of 288 residents responded to a questionnaire regarding subjective physical symptoms, sociodemographic characteristics and clean-up activities that occurred between two and eight weeks after the accident. Additionally, the urine of 154 of the respondents was analyzed for metabolites of volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs) and heavy metals. To compare the urinary levels of exposure biomarkers, the urine of 39 inland residents who were not directly exposed to the oil spill were analyzed. Results: Residents exposed to oil remnants through clean-up work showed associations between physical symptoms and the exposure levels defined in various ways, including days of work, degree of skin contamination, and levels of some urinary exposure biomarkers of VOCs, metabolites and metals, although no major abnormalities in urinary exposure biomarkers were observed. Conclusions: This study provides evidence of a relationship between crude oil exposure and acute human health effects and suggests the need for follow-up to evaluate the exposure status and long-term health effects of clean-up participants.

One of the primary goals of epidemiology is to quantify various aspects of a population's health, illness, and death status and the determinants (or risk factors) thereof by calculating health indicators that measure the magnitudes of various conditions. There has been some confusion regarding health indicators, with discrepancies in usage among organizations such as the World Health Organization the, Centers for Disease Control and Prevention (CDC), and the CDC of other countries, and the usage of the relevant terminology may vary across papers. Therefore, in this review, we would like to propose appropriate terminological definitions for health indicators based on the most commonly used meanings and/or the terms used by official agencies, in order to bring clarity to this area of confusion. We have used appropriate examples to make each health indicator easy for the reader to understand. We have included practical exercises for some health indicators to help readers understand the underlying concepts.

소 품종 판별을 위해 DNA 마커 정보는 품종을 구별하거나, 형질을 구분하는데 있어 꾸준히 이용되고 있다. 본 연구에서는 Finnzymes (DIAGNOSTICS)사의 Bovine Genotypes Kit Ver1.1/2.1을 농촌진흥청 국립축산과학원이 보유한 호주산 및 미국산 수입우 DNA 샘플 148두/국내산 육우 DNA 샘플(Holstein) 170두와 정읍지역 한우 DNA 샘플 177두에 적용하여 한우품종 식별력을 분석 하였다. Bovine Genotype Kit 1.1은 11개의 ISAG MS 마커로 이루어져 있으며, 여기에 5개 MS 마커가 추가된 ver2.1 Kit를 사용하여 집단별 유전자형 데이타를 구축하였고, MS Tool kit 분석 및 Phylip program 분석을 수행하여 Phylogenetic tree를 작성하였고, Genotype 분석 프로그램인 GeneClass 2.0 (INRA/France)을 이용하여 품종 식별력을 추정하였다. 분석 결과 95% 이상의 정확성을 가진 한우 식별력은 100%로 나타났고, 호주산 수입우 95.3%, 국내산 육우는 90%의 높은 식별력을 각각 나타내었다. 따라서 Finnzymes 사의 상용화된 16종의 MS 마커는 한우집단의 유전적 특징을 객관적으로 구분하여 수입쇠고기/젖소고기/한우쇠고기에서 간편하게 한우개체 및 품종식별에 활용될 수 있는 가능성과 특히 국내에서 비육된 육우(젖소)를 수입산 쇠고기로부터 식별할 수 있는 장점이 있을 것으로 사료된다.
