This study examined the demographic and oral behavioral risk factors for periodontal disease in adult workers. The research subjects and method were conducted targeting 1,650 Korean adult workers aged 20-64 utilizing the data from the fifth Korea National Health and Nutrition Examination Survey (KNHANES V-3). As a result of this study, the periodontal tissue patients showed the risk factors for gender, age, income level, educational level, systemic disease, sleep hours, oral health level, biting trouble, and chewing difficulty. In terms of the greatest influence, the workers with problems with biting and chewing had a more than 3.5 times higher likelihood of being affected by periodontal disease. The findings of this study show that there are a variety of risk factors for periodontal diseases in Korean workers. To reduce the prevalence rate of periodontal disease, regular checkups including dental checkups and sufficient sleeping will be necessary, and the level of stress should be decreased. In addition, the government should take the required measures to remove the socioeconomic inequality, such as income gap or educational divide.

The purpose of this study was to obtain basic data for nutrition education of the children in a health promoting elementry school. The data was collected by a questionaire of food habits, and anthropometric measurement and biochemical test in comparison with obesity index. The study subjects were boys and girls aged 10 to 12 years who participated in the “99 Children Nutrition Camp”. The average obesity index was 1.7$\pm$21.6% in boys and -11.4$\pm$12.6% in girls. After school, major leisure items were significnatly different by gender but both boys and girls played mainly computer game. In concern for body image and eating habits, girls had more concern and girls had attempted weight control more than boys. 80.2% of subjects had prejudice for special food, especially, all subjects in the severely underweight group had prejudice. But this tendency was significantly decreased with the increasing obesity index. The lowest preferency was for vegetables(64.4%). The tendency of prejudice of subjects was higher whose mother are thirties than those of subjects whose mother are in fourties. The serum GOT and GPT values were significantly higher in overweight and obese group than the other groups. The only serum T-chol was significantly higher in boys than in girls. The number of risk factors related to coronary heart disease(CHD) based on coresponding criteria of TG, T-chol, HDL-chol, and LDL-chol was not increased significantly with the degree of obesity index. The results indicated the need of nutritional management for the children. At a point of view, to educate children early who are able to change food habits and life-styles means to help heathy growth and to deliver up heathy adults. Active nutrition education for both children and mothers will be recommended with joint participation of nutritionists in community public health center and elementary school.

The purpose of this study is to provide base line data required to establish a viable knitwear marketing strategy targeting young people by comparing and analyzing preference and buying behavior of customers in their twenties. A survey was conducted in 2009 and 2013 on people in their 20's male and female living in Busan. The total of 362 people participated in the survey and the results are as follows: Firstly, the seeking factors for knitwear were utilization factor, functionality factor, care for clothing factor, economics factor and vogue factor. Secondly, a differentiated marketing strategy targeting 20-something customers needs to be established as there was a steep rise in the number of customers purchasing clothes on online shopping malls using smart phone devices according to the survey.'Low-price, broad-line strategy'is also required as those surveyed preferred stores offering a wide choice of designs with reasonable price. Considering the survey results that a growing number of people tended to buy a variety of knitwear items regardless of the seasons, knitwear production needs to be diversified in terms of designs and materials. Thirdly, the survey revealed that pastel-colored knitwear was preferred for spring/summer season whereas knitwear with achromatic colors was voted the most-preferred one during the autumn and winter season. In terms of knitwear shapes, the gap between genders continues to narrow and tendency sensitive to fashion trend became more apparent reflecting the change of the times.

The purpose of this study is to survey middle school students’s awareness of sexuality and relationships with the opposite sex. The students need to have at their disposal basic resources on sexuality education and an established and systematic curriculum. To achieve this result, questionaires were distributed to 640 students who were chosen randomly in three middle schools in Seung-ju Goon and Goo-rye Goon in Chonnam area, 573 questionaries were used for the final analysis. The results were as follows： In the area of awareness of sexuality, male students regarded sex more positively than female students. It also showed that 19.9% or male students and 17.6% of female students were not aware of their virginity. Male students said they felt sexual impulses most when they saw naked women, and secondly, by sex magazines. This indicates students are motivated mostly by outside influences. There is a considerable gap in the degree of sexual knowledge between male and female according to their school year and father’s family education level. However, little difference is seen according to student’s family circumstance, father’s education level. However, little difference is seen according to student’s family circumstance, father’s job, and student’s religion and vise versa. School restrictions were so severs that 48.2% of boys and 47.1% of girls said that schools paid little attention to their needs. The school restricted rather than permitted relationships with opposite sex. Most of the students revealed a dissatisfaction with the school sexuality education program. Because of confucianism, Korean society has a negative attitude towards sexual activity including sexual education in the schools. 56.8% of male students and 81.4% of females students wanted female teachers to be their sexuality education teachers or advisors rather than male teachers, and 44.8% of male students and 51.2% of females students wanted to receive sexuality education in their Home Economics classes. Materials for sexuality education were considered most effective through videos and audio-visuals. As a result, this survey showed that there appeared to be a great need for a sound, effective, and sensitive sexuality education curriculum in the middle schools for teenagers. It should be conducted in such a way that the teenagers will learn about their sexual needs, their gender differences, and understand and know how to conduct themselves in today’s society sexually.

Objectives: The purpose of the study was to identify a gap between consumer characteristics and utilization of health information on the Internet. Methods: A telephone survey of nationally representative samples was conducted using structured questionnaires, and 1,000 of the 1,189 responses obtained were included in our analysis. The following variables were included in the analysis as potential predictors of health information use on the Internet: predisposing factors such as gender, age, and education status; enabling factors such as region and monthly household income; consumer need for health information; and attitude to health. Multiple logistic regression analysis was used to evaluate the association between utilization rate and the potential predictors. Results: Thirty-nine percent of consumers had obtained health information on the Internet over a one-year period. The utilization rates were higher for consumers who were young, educated, worked in the office setting, had higher incomes, wanted health information, and were able to use the Internet. The utilization rate was 5.35 times higher in the younger group (20-30 years) than in the elderly group (95% CI=2.21-12.97); 2.21 times higher for office workers than for manual workers (95% CI=1.16-4.20); 3.61 times higher for college graduates than for middle school graduates and below (95% CI=1.07-11.59); 1.99 times higher for people with monthly household incomes over 3,000,000 won than for those with monthly household incomes below 1,500,000 won (95% CI=1.01-3.92). Conclusions: There needs to be a paradigm shift, with consideration of not only Internet accessibility in the digital age, but also consumer ability and attitudes toward utilization of health information.

This study is to demonstrate the effects of working hour on the workers' subjective well-being. Working hour, in this study, means working time per a day and the generosity of weekly holiday. Firstly, the effects of working hour on the worker's well-being will be analyzed. Secondly, it will be investigated if the effects of working hour on the worker's well-being change according to the existence of the family member who needs care. The results of the analysis show that longer working hour and the lower generosity of weekly holiday decrease workers' well being. If workers have family member who needs care, the effects of working hour and the generosity of weekly holiday on the worker's well-being are not significant. It contrasts to the result that women are more satisfactory to their lives than men in cases they don't have family member who needs care. It is supposed that these results are closely related with the enormous gender gap of care time in Korea.

Financial literacy is one of the sustainable development goals of huge concern of governments. Governments explore solutions addressing policies to improve financial literacy. Nevertheless, financial management has such a broad scope and is not just limited to knowledge. As human nature, individuals are born with different confidence levels that include various financial abilities. This study aims to investigate the household-financial efficacy through the application of psychometric instruments, risk preference, and demographic characteristics toward consumption decision behavior. The research is based on a survey 479 households in the peninsular Malaysia, and utilizes the structural equation model, cluster proportional and systematic random sampling, and two measurements - composite reliability and average variance extracted. Results show that households' financial efficacy is one of the critical factors that explain the households' consumption decision behavior. Also, risk preference, gender and area location (rural or urban) of the household determined the consumption decision behavior of the household. The effectiveness of consumption decision is not only determined by financial literacy, but also financial efficacy. The implications of this paper may help to design policies in narrowing the broad gap between the rural and urban level of financial efficacy. The government needs to take appropriate actions to fix it.

Objectives: The study was designed to evaluate the efficacy of performing a second, repeat anterior maxillary distraction (AMD) to treat residual cleft maxillary hypoplasia. Materials and Methods: Five patients between the ages of 12 to 15 years with a history of AMD and with residual cleft maxillary hypoplasia were included in the study. Inclusion was irrespective of gender, type of cleft lip and palate, and the amount of advancement needed. Repeat AMD was executed in these patients 4 to 5 years after the primary AMD procedure to correct the cleft maxillary hypoplasia that had developed since the initial procedure. Orthopantomogram (OPG) and lateral cephalograms were taken for evaluation preoperatively, immediately after distraction, after consolidation, and one year postoperatively. The data obtained was tabulated and a Mann Whitney U-test was used for statistical comparisons. Results: At the time of presentation, a residual maxillary hypoplasia was observed with a well maintained distraction gap on the OPG which ruled out the occurrence of a relapse. Favorable movement of the segments without any resistance was seen in all patients. Mean maxillary advancement of 10.56 mm was achieved at repeat AMD. Statistically significant increases in midfacial length, SNA angle, and nasion perpendicular to point A distance was achieved (P=0.012, P=0.011, and P=0.012, respectively). Good profile was achieved for all patients. Minimal transient complications, for example anterior open bite and bleeding episodes, were managed. Conclusion: Addressing the problem of cleft maxillary hypoplasia at an early age (12-15 years) is beneficial for the child. Residual hypoplasia may develop in some patients, which may require additional corrective procedures. The results of our study show that AMD can be repeated when residual deformity develops with the previous procedure having no negative impact on the results of the repeat procedure.

Tremendous progress has been made over the past quarter-century studying the genetics of gametogenesis and the resulting gametes and embryos. Studies merging molecular techniques and conventional cytogenetics are now beginning to bridge the gap between what we have learned about the meiotic process in males and females and what we know of the mitotic chromosomes of zygotes. Numerical abnormalities in sperm, oocytes and embryo can now diagnosed by fluorescence in situ hybridization (FISH). "At risk" couples can, therefore, have only unaffected embryos replaced in the sterus and avoid the possibility of terminating a pregnancy that might only be diagnosed as affected later gestation. Single-cell genetic analysis has also provided powerful tools for studying genetic defects arising during early human development. Recent studies of sperms, oocytes and cleavage-stage human embryos have revealed an unexpectedly high incidence. These genetic abnormalities are likely to contribute to early pregnancy loss and have important implications for improving pregnancy rates in infertile couples by assisted reproduction. The widespread use of preimplantation genetic diagnosis (PGD) awaits further documentatio of safety and accuracy. Other issues also must be addressed. First, the ethical issues regarding germ cell and embryo screening must be addressed including what diseases are serious enough to warrant the procedure. Another concern is the use of this technology for non-genetic disorders such as gender selection. Finally, the experimental nature of these procedure must continually be discussed with patients, and long-term follow-up studies must be undertaken. Development of more accurate and less expensive assays coupled with improved assisted reproductive technology success rates may make PGD a more widely use clinical tool. The future awaits these development.velopment.
