This study purposed to analyze difference in experience of life in Korea among adolescents whose immigrant backgrounds were different (Korean-born children of multicultural families and foreign-born immigrant children) using the data of the 2012 National Survey of Multicultural Families (adolescent children aged between 9 and 24). According to the results of analysis, first, multicultural adolescents with immigrant backgrounds experienced 'difficulty in using the Korean language (speaking, listening, reading, and writing),' 'school dropout,' and 'school violence' more frequently than Korean-born multicultural adolescents. Second, with regard to social discrimination (friends, teachers, relatives, neighbors, and unknown people), multicultural adolescents with immigrant backgrounds experienced 'discrimination by teachers,' 'discrimination by relatives,' 'discrimination by neighbors,' and 'discrimination by unknown people' more frequently than Korean-born multicultural adolescents. By analyzing these differences, this study suggested directions for differentiated support policies and specific strategies for adjustment to life in Korea by multicultural family adolescents with different backgrounds.

The study was conducted to evaluate consumer awareness of the risk elements associated with foods and their information search behavior regarding food safety. The data were collected from 504 adult consumers living in Seoul, Busan, Incheon, Daegu, Daejeon, and Gwangju through a self-administered questionnaire on August, 2006. Frequency analyses, t tests, one-way analysis of variance, and Duncan's multiple range comparison tests were conducted to analyze the responses using SPSS v. 14.0. The levels of recognition of consumers regarding each risk element were generally low. Many respondents answered that they obtained information regarding food safety from TV/radio/newspapers and family/relatives/friends/neighbors. The respondents also indicated that they had strong confidence in the information from family/relatives/friends/neighbors. Additionally, most respondents required information regarding heavy metal contamination, endoctrine disruptors, and avian influenza.

Two culture-independent methods, namely ribosomal DNA libraries and denaturing gradient gel electrophoresis (DGGE), were adopted to examine the microbial community of a Malaysian light crude oil. In this study, both 16S and 18S rDNAs were PCR-amplified from bulk DNA of crude oil samples, cloned, and sequenced. Analyses of restriction fragment length polymorphism (RFLP) and phylogenetics clustered the 16S and 18S rDNA sequences into seven and six groups, respectively. The ribosomal DNA sequences obtained showed sequence similarity between 90 to 100% to those available in the GenBank database. The closest relatives documented for the 16S rDNAs include member species of Thermoincola and Rhodopseudomonas, whereas the closest fungal relatives include Acremonium, Ceriporiopsis, Xeromyces, Lecythophora, and Candida. Others were affiliated to uncultured bacteria and uncultured ascomycete. The 16S rDNA library demonstrated predomination by a single uncultured bacterial type by >80% relative abundance. The predomination was confirmed by DGGE analysis.

Two new species, Thelopsis ullungdoensis and Phylloblastia gyeongsangbukensis are described from Ullung-Do (Island), South Korea. The closest relatives from Europe and Korea are epiphytic Thelopsis flaveola which differs by their immersed or semi-immersed yellow ascomata, ascospores without halo and their habitat of smooth bark (mainly Fagus) in humid and cold climates. Thelopsis gangwondoensis differs by its bigger semi-immersed ascomata (600-700 ㎛ in diam.), oblong halonate ascospores (8-12 × 6-8 ㎛) and its habitat of smooth bark of deciduous trees. P. gyeongsangbukensis differs from its relatives within the genus in having 5-septate ascospores (22-26 × 6-8 ㎛), semi-immersed, subglobose ascomata with a flattened top (250-400 ㎛) and a thin, matt, uneven gray-brown to gray-green continuous thallus without isidia.

Golestan province has a reputation for relatively high incidence rates of gastric cancer in Iran. Along with dietary, lifestyle and environmental influential factors, soil selenium and high levels of pesticide used may exert influence in this region. The present study was designed for modeling the influential predictors on incidence of gastric cancer in Golestan. All registered cases of gastric cancer from March 2009 to March 2010 (49 females and 107 males) were investigated. Data were gathered by both check list and researcher made questionnaire (demographic, clinical and lifestyle characteristics) and analysed using logistic regression. Mean (${\pm}SD$) age at diagnosis was $62.9{\pm}13.8$ years. CIR and ASR of gastric cancer showed 9.16 and 13.9 per 100,000 people, respectively. Based on univariate logistic regression, a history of smoking (OR= 2.076), unwashed hands after defecation (OR= 2.612), history of cancer in relatives (OR= 2.473), history of gastric cancer in first-degree relatives (OR= 2.278), numbers of gastric cancers in first-degree relatives (OR= 2.078), history of X-ray and dye exposure (OR= 2.395), history of CT scan encounter (OR= 2.915), improper food habits (OR= 3.320), specific eating behavior (OR= 0.740), consumption of probable high risk foods (OR= 2.942), charred flesh (OR= 1.945), and animal fat (OR= 2.716) were confirmed as a risk factors. Changes in lifestyle may be expected to increase gastric cancer incidence dramatically in the near future. Therefore, appropriate educational interventions should be designed and implemented by competent authorities.

The purpose of this study is to research support systems of the community child care services for optimum work-family balance. For this purpose, the questionnaire to be completed combined four areas: the workplace, school, community and home. Then questions concerning demographic factors and community-related aspects were analysed for this article. After analyzing 197 questionnaires, supplementary questions were asked, by interview to 10 samples. Full-time working wives (eg. working from 9am to 6pm) who have 1 or more children under 10 years old, living in Seoul and Gyeonggi province were collected as samples. The results were as follows: First, child care from family and relatives, and community services was properly used during the week, but dual working parents took complete charge of child care on Saturdays. Second, emergency child care was usually provided by the family, while relatives and community child care services were used less. Third, parents spent 17% of their monthly income on total child care expenditure. Fourth, community child care services were not used often, but the level of satisfaction with them was very high. Finally, they used relatives' services for safety reasons and community services for location, and only based on informed decisions. Therefore, Saturday child care programmes need to be initiated to help physically and mentally tired parents, with more general provision of positive and diverse public support systems.

This research was performed to screen the cytotoxic activities of some pharmaceutical insect relatives. Cytotoxic activities of total extract and fractions of hexane, ethyl acetate, methanol, water and boiling water were extracted from four pharmaceutical insect relatives: the Chinese gall, the cicada slough, the hornet nest and the batryticated silkworm. These extracts were investigated against the cancer cell lines of L1210, P388 and SNU-1 in vitro tests. Results showed that, ED, , against the cancer cell lines of L1210, P388 and SNU-1 were 0.55, 0.50, and $0.83{\mu}g/ml$ in the ethyl acetate fraction from the Chinese gall; 1.07, 2.19, and $2.24{\mu}g/ml$in the ethyl acetate fraction, 1.51, 1.26, and $1.45{\mu}g/ml$ in the water fraction and 1.48, 2.29, and $1.29{\mu}g/ml$in the boiling water fraction from the cicada slough; 3.31, 2.00, and $6.61\mug/ml$ in the water fraction from the hornet nest and 13.80, 19.95, and $31.62{\mu}g/ml$in the hexane fraction and 33.88, 21.88, and $25.12{\mu}g/ml$in the ethyl acetate fraction from the batryticated silkworm, respectively. All of the fractions mentioned above showed high cytotoxic activities and could be suggested for further studies in vivo tests.

Objectives : This study aims to examine the effects of death education program on meaning in life, death anxiety and attitude toward nursing care of the dying patients among nursing students. Methods : Subjects were 155 nursing students of the K college. Before and after the intervention, students responded a questionnaire developed to measure meaning in life, death anxiety and attitude toward nursing care of the dying patients. To analyse the data, Cronbach's ${\alpha}$, t-test, and paired t-test were used with an SPSS 12.0 program. Results : 1. Meaning in life and attitude toward nursing care of the dying patients levels significantly increased, death anxiety levels significantly decreased. 2. Meaning in life levels increased significantly in the 20-24 age group, female, first grade, no religion, no death experience of relatives. 3. Death anxiety levels decreased significantly in the 20-24 age group, female, no religion, no death experience of relatives, but increased significantly in a buddhist group. 4. Attitude toward nursing care of the dying patients levels increased significantly in the 20-24 age group, female, first grade, won buddhist, no death experience of relatives. Conclusions : This study, through the above result, shows that the death education program can be an effective nursing education to improve meaning in life and attitude toward nursing care of the dying patients and to decrease death anxiety. These results suggest that the death education program will be helpful for recognizing the values of themselves and their current lives and improving their nursing intervention care of the dying patients.

This paper describes hierarchically stratifying and analyzing haplotrees of haplogroups from haplotypes on the Y and X chromosomes of human cells for genetic and Korean traditional and genealogical trees. The specific region is Chungcheong province, and the Y-DNA of the paternal lines has high frequency of O3a∗ and O2b∗ in the O group, and the mtDNA of the maternal line has a relatively high frequency of D∗ and M∗ in the L3 group. Each combination of these constructs the family tree of the father lines and mother lines. Genetic distances using Nei's standard genetic distance, are very close relatives of less than 0.1 and close relatives of 0.1 to 0.8. Provided, the distance is more than 1.0, it is difficult to estimate relatives. STR has the identified kinship, and SNP has the personal genetic identification. A scientific stratification of the Korean genealogical tree is created by the three factors.
