  • Research has consistently reported a strong association between spouse abuse and problem drinking. The primary aim of this study was to examine the role of spouse abuse as mediator between the husband's problem and wife's problem drinking. Data from 1st year Korea Welfare Panel were used for the analysis. Subjects in this study consisted of 3,284 male household who aged between 19 years old and 64 years old. The statistical significance was tested by SPSS 18.0, AMOS 18.0. The findings of the study were as follows: First, husband's problem drinking were significantly affected to the wife's problem drinking. Second, there was a strong association between husband's problem drinking and spouse abuse. Third, spouse abuse worked as mediators between the husband's problem and wife's problem drinking. Based upon these findings we suggest to develop an integrated substance abuse-domestic violence treatment program. The implications and limitations of these findings were discussed, and directions for future studies were also proposed.

  • Purpose: The aim of this study was to compare with color reproducibility of the coating method and dipping method using a colour liquid. Methods: Two groups of square-shaped specimens ($10mm{\times}10mm$ in diameter, 1.5mm thickness) were prepared for analysis(n=15/group). The CM(Coating Method) group was fabricated as full zirconia specimens with the coating coloring method and Group DM(Dipping Method) was prepared as specimens of 0.7 mm-thick zirconia plate using the dipping coloring method and veneered with 0.8mm-thick porcelain. Color parameters were measured with ShadeEye $NCC^{(R)}$ spectrophotometer and color differences were calculated using the equation ${\Delta}E^*= \{({\Delta}L^*)^2+({\Delta}a^*)^2+({\Delta}b^*)^2\}^{1/2}$. Non-parametric statistical methods, the Mann-Whitney test, and the Kruskal-Wallis test were used to analyze the data. Type one error rate was set at 0.05. Results: Color difference values larger than 7 were observed between specimens with the coating method and the dipping method, which were detectable difference in a clinical setting. Conclusion: Cautious application of the coating coloring method in a clinical setting and further researches to standardize the coating method are needed.

  • In this paper, we quantiatively analyze the broadband CDMA systems with high chip rate, which virually eliminates the multipath fading effects by distinguishing each reflected paths in the process of despreading. We model the broadband multipath propagation channel with random time-variant impulse response as a linear filter of tapped delay line to evaluate the performance of broadband CDMA systems in multipath fading environment. This statistical model, based on extensive experimental data, was established to characterize the urban radio propagation medium in various environments. We perform computer simulation of the transmission and reception of broadband CDMA systems by applying it to abve channel model. From the simulation results, we confirm that the broadband CDMA systems inherenly reduce the effects of multipath fading phenomena which causes to degrade the performance of mobile communication systems, based on the results of eye-diagram and BER curve.

  • Newly born lambs have to face challenges in a new environment totally different from that of the uterus. Adaptation to extra-uterine life involves functional changes with almost each organ and system in the body undergoing a series of metabolic and anatomical modifications. Failure to adapt the extra-uterine environment can not only lead to homeostatic disturbances but also lead to the death of the affected lambs. Hematological parameters of newly born lambs show variability that differs between breeds of lambs. The purpose of present study was to determine homeostatic responses and physiological reference values in Kajli breed lambs occurring in the neonatal period through changes in blood profile, respiratory rate, heart rate, live weight and rectal, scrotal and skin temperatures. For this purpose, sixteen clinically fit lambs (males = 10 and females = 6) with a mean body weight $6.92{\pm}0.46$ kg were selected. Physiological data of selected parameters of each Kajli lamb was recorded at three day intervals and hematological parameters at five days for a period of 30 days. In general, statistical analysis showed a significant effect of time (p<0.001) on all the studied physiological and hematological parameters except platelets counts, white blood cells and hemoglobin concentration. The results documented in the current study are an addition to existing knowledge of the physiology of Kajli sheep breed should be helpful in developing feeding, disease diagnoses and treatment protocols for newborn Kajli stock.

  • At the opening of a new millennium and a new century, health promotion and education services in Korea are in the early developmental stage. The National Health Promotion Act legislated in 1995 was a milestone for initiating a national and local health promotion program in Korea. And since then local governments and health centers have been developing and providing health promotion program for the community populations. The short history of health promotion and education in Korea has meant that local governments and health centers have a limited experience and organizational capacity for health promotion and education planing and practice. This study was attempted to measure health education need of rural community and to analyze the factors for health education need assessment. Surveyors interviewed 1250 subjects randomly selected. Subjects were 2.17% of men and women in Changnyung county and older then 20 years old. Data were collected from April 17, 2000 through April 27, 2000. The questionnaire consisted of general characteristics, health educational experiences, health educational method, health educational content and health educational needs for rural community residents. The questions on the health educational needs of content consist of 36 questions in 8 fields. The statistical methods used for the analysis were $X^2$-test, t-test, F-ratio and ANOVA using SPSS program. In conclusion, despite more needs to the respondents who are in the low education level and socioeconomic state, in the old age, in the low health knowledge, they required less health education. To enjoy a more healthy life after more community residents actively understand and are interested in health education and health promotion, we certainly require a designed and systemic health education. The resources of health department in Korea are limited and the investment involved in health promotion and health education is severely reduced. Particularly this situation is more severe in the rural community. To select and perform an effective health education methods that the nature and reality of the rural community are considered, well use the resources to invest in health promotion affairs as effectively as possible and then they will take the responsibility of healthy community.

  • Objectives: The present study examined whether smoking rate has declined in 1992-2006 and who the high risk groups were on industry classification and employment type. Methods: Data from 91,263 persons aged 25-64 years were analyzed from three rounds of the Social Statistical Surveys of Korea between 1992 and 2006. Industry indicators were divided by the 9th Korean Standard Industrial Classification. Age-adjusted prevalence of smoking was calculated. Prevalence ratios(PR) and differences(PD) were estimated using log-binomial regression analysis. Results: Age-adjusted prevalence of smoking decreased between 1992 and 2006, specially the smoking prevalence of regular employees decreased most. PD in age-adjusted prevalence of smoking were the biggest between regular and daily employees. PR of the temporary employees', daily employees', self-employed persons' in order was wider than that of regular employees. PR increased significantly increased between 1999 and 2006 for those in manufacturing, construction, wholesale & retail trade, service industries. Increases in PR(regular/irregular) for women in service industry were statistically significant. Conclusions: Despite reducing overall cigarette smoking rates in males, the smoking rate was not reduced equally by industry classification and employment type in both genders. More adjustable antismoking policies and consideration of employment type are requested to reduce inequalities in smoking.

  • Litterfall has been recognized an important part of the forest ecosystem production, playing a major pathway in energy flow and nutrient cycling through the ecosystem. This study was carried out to examine the quantity and components, temporal variation, and spatial heterogeneity of the litterfall in the mixed broadleaved-Korean pine forest. The data were collected from the 9ha permanent experimental plot, of which on the center area, i.e. $150m{\times}150m$, the total number of 319 circular litterfall traps with the size of $0.5m^2$ were established to collect falling litterfall. The results showed that the annual amount of litterfall was totalized 3,033.7 kg/ha, occupying broad-leaves of 39.3%, conifer-leaves of 29.5%, others of 18.5%, branches of 10.4%, and seeds of 2.3%. The peak point of the litterfall production was made at the end of September, proportionating 32.2% of total amount. The analysis of semivariogram revealed the existence of high spatial heterogeneity, calculated the scale of spatial heterogeneity ranged from 11.6 m to 29.1 m. The result of proportion (C/[Co+C]) showed that spatial heterogeneity of autocorrelation in total spatial heterogeneity were from 97.0% to 100%. The relatively heavy branches and others had significant differences in litterfall production between the areas of canopy gap and closed canopy in the 95% probability level, but the other components did not show statistical differences.

  • In Korea, metropolitan cities and provinces are responsible for setting up their own Regional Forest Plans to manage the forests at regional scales distinguished by administrative boundaries, and the role of the plans are very crucial by linking the Forest Basic Plan for nationwide forest management policy with Forest Management Plans for local-level forest management practices. Thus, the analysis of forest resources at regional levels is required to make more efficient regional forest plans by properly reflecting regional forest situations. This study aims to present which species are concentrated at each individual metropolitan city or province, contributing to more efficiently establishing its regional forest plan. In order to measure the concentration levels of species for each region, Location Quotient and Relative-Specialization Index are computed using area- and volume-data for the major species selected in the Statistical Yearbook of Forestry. As a result, the ranks among the indices of the major species for each individual municipal city and province are presented. The results from this study can contribute to the selection of regional target species and establishment of regional forest management objectives. Further study regarding the differences between the results from area-based and volume-based indices will be helpful to consider regional level productivity by species into the regional forest plans.

  • This study was to provide the fundamental data for a scientific and rational clothing construction by investigating the length variation of the upper arm surface, using the method of surgical tape, and to understand the expansion and contraction of parts of body for the making of clothing adaptable to movement. The subjects were li early elementary schoolgirls in Busan area classified with three somatotypes, and arm-movements consisted of 6 types. The statistical analyses used in this study were mean, standard deviation and the ANOVA and LSD procedure. The results of the analysis of the length of the upper arm surface are as follows: By arm-movements, in the items of horizontal, upper arm length changed more in the front than in the back, and in the items of vertical, represented the opposite of horizontal items. In the items of upper arm, the anterior-posterior axilla length and under arm length were influenced by arm-movements, and the under length of the upper arm represented the maximum rate increase of 74.59%(3.20cm)$\sim$138.72%(4.28cm). In the somatotypes of early elementary schoolgirls, type II was more influenced by arm-movements, and for the making of clothing adaptable to movement, type III needed to reflect more surplus length(2cm) than the other types.
