Many pharmaceutical products are available through prescription (Rx) only status. As a result, access to physicians and insurance coverage play a key role in the use of these products, and therefore may affect the population to whom advertising is targeted at. The movement of pharmaceutical products from prescription (Rx) to Over-the-Counter (OTC), or Rx-to-OTC switch changes the cost of acquiring the drug and therefore may change the incentives manufacturers have at targeting particular population segments. This study examines whether Rx-to-OTC switch changes the frequency and the distribution of who is exposed to pharmaceutical advertising. Using an archive of pharmaceutical advertisements and National Consumer Survey, this study examines how individuals with particular demographic characteristics are exposed to pharmaceutical advertisements before and after drugs are moved from Rx to OTC. The results provide evidence that individual's advertising exposure increases after Rx-to-OTC switch. Moreover, the increase in advertising exposure is greater for the low socioeconomic status (SES) consumers which implies they may get more information about the disease, treatment and product after the Rx-to-OTC switch through advertising. If low SES consumers have more exposure to the advertising after products switched to OTC, then FDA policies regulating this switch should recognize the potential role of advertising providing access to health-related information.

본 실험은 음나무 배발생 세포의 증식 및 체세포배 발달을 위한 액체 현탁 배양조건의 확립을 위해 수행되었다. 배발생 세포의 생장율은 접종 밀도가 증가할수록 감소하였다. 배발생 세포의 증식에 가장 효과적인 접종 밀도는 0.1 g/100 ml 로서 이 농도에서 세포의 생장율이 가장 높았다. 배양기간에 따른 배발생 세포의 생장 패턴 및 세포 주기 (G1, S, G2/M) 분석 결과, 세포의 생장은 배양 5일 후부터 증가가 시작되어 15일 까지 급격히 생장하였으며 그 이후에는 점차 감소하였다. 배양 기간 별 세포 주기 (cell cycle)의 변화가 명확하게 관찰되어 배양 5일째 5기는 초기의 5.5% 에서 11.7%로 두 배정도 증가하였으며, 배양 15일 이후부터는 다시 초기의 세포 주기로 되돌아가면서 안정화되는 것으로 나타났다. 따라서 음나무 배발생 세포의 현탁배양은 15일의 주기로 배양하는 것이 증식에 가장 효과적인 것으로 생각되었다. 한편 배발생 세포에서 체세포배의 유도는 배양초기의 접종 밀도가 중요한 것으로 나타났다. 0.5 g/L 의 낮은 밀도로 접종 시에는 65% 이상의 어뢰형 배가 유도된 반면 접종 밀도가 높아질수록 어뢰형으로의 배발달은 급격히 감소하였다. 초기의 접종 밀도가 증가할수록 특히 어뢰형 배의 발달은 지연되었으나 구형 및 심장형 배의 유도는 초기 접종밀도에 영향을 받지 않았다. 이상의 실험결과로 음나무 액체 배양 시 초기 접종 밀도를 조절함으로써 배발생 캘러스의 증식 및 체세포배를 효과적으로 유도할 수 있었으며 이는 체세포배 생산을 위한 배양 기간의 단축이 가능함을 보여주는 결과이다.

Objectives : Psychological comorbidities are high in patients with obesity and are associated with a variety of medical and dietary problems. This study aims to examine the association between psychological factors and obesity. Methods : This study was performed in pre-menopausal obese($BMI{\geq}25kg/m^2$, waist circumference ${\geq}85cm$) women in Seoul, in 2008 (n=35). Every patient underwent the obesity treatment program. The program included dietary and exercise education, and abdominal mesotherapy for 6 weeks. Simple anthropometry including weight, BMI and Computed Tomography (CT) including Subcutaneous adipose tissue (SAT), Visceral adipose tissue (VAT) and Visceral adipose tissue/Subcutaneous adipose tissue ratio (VSR) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory(SRI) questionnaire were administered. Results : 1. All of the obesity indicators (except VSR) decreased significantly after the obesity treatment program. 2. There was a significant relationship between self esteem (SES score) and visceral obesity (VAT and VSR) measured at the end of the program. 3. During the intervention, the more weight, BMI, and subcutaneous adipose tissue decreased, the more self-esteem (SES) increased. There was no relationship between depression (BDI) and obesity. And the change in stress response (SRI) was associated with the change of deep subcutaneous adipose tissue and total abdominal adipose tissue. Conclusions : This study proves that visceral obesity may contribute to low self-esteem, and there is a possibility that the other psychological factors could also be related with obesity in Korean obese women. Individualised antiobesity therapy may be required depending on the patient's psychological characteristics and weight loss could be helpful in order to treat psychological problem in obese patients.

Objectives : The objective of this study was to assess a level of oral health related quality of life(OHRQoL) for rural communities elderly and to determine the association between OHRQoL and socio-economic position. Methods : The study population was elderly(60+year-old) residents of PyeongChang county, Jeongseon county, Yeongwol county, Gangwon province. A total of 171 people were invited to participate. Oral health related quality of life was measured using the GOHAI. The data were analyzed with Mann-Whitney U test or Kruskal-Wallis test and to assess socio-economic inequalities in OHRQoL(GOHAI), we used multi-variable logistic regression models. We used models adjusting for age, sex, family status factors(Model I) and compared them to models additionally adjusting for stress level(Model II). Results : There were significant differences in lower score of GOHAI at lower age group and live alone group. And we found that lower SES was significantly associated with lower score of OHRQoL. Social gradient in the score of OHRQoL persisted when adjusted for age, sex, family status, stress level. Conclusions : We recommend that oral health promotion program should be developed after due consideration SES for rural communities elderly because OHRQoL of rural communities elderly was low and association between SES and OHRQoL for rural communities elderly.

Children from low-income families are vulnerable to variable psychological and emotional stress related to financial issues and dysfunctional families. The subjects were 15 1st to 3rd graders who were low on the Self Esteem Scale (SES). They were attending an after-school center for elementary school students. They participated in three art therapy groups from April to October 2005. Children's depressive symptoms and self-esteem were assessed using the Children's Depression Inventory (CDI) and an observational check-list. Results showed that the group art therapy program brought about significant effects on increasing self-esteem of the children and reducing depressive symptoms, showing that group art therapy can facilitate emotional and psycho-social growth of children from low-income families and can be developed in family-based community programs.

Objectives: The purpose of this study is to examine change in adolescent depression across time and to determine the relation between individual and neighborhood socioeconomic status (SES) and depression. Methods: This study employed multilevel latent growth analysis using longitudinal data from Korea Children and Youth Panel Survey. A sample of this study consists of 2,351 adolescents who were in first grade of middle school in 2010. Results: Results showed that both initial level and downward trajectory of depression varied significantly across individuals as well as across neighborhoods. On the individual level, self-rated economic condition(b=-0.203, p<.001) was related to the initial level of depression. Adolescents whose father had a high educational level(b=0.028, p<.001) or whose mother had a low educational level(b=-0.022, p=.011) had lower rates of decline in adolescent depression. On the neighborhood level, neighborhood deprivation index (b=0.003, p=.019) and gini coefficient(b=0.124, p=.040) were associated with lower rates of decline in depression. Conclusions: Low SES in adolescence is correlated with worse mental health, especially depression. Social disparities in depression likely originate before adulthood. The findings argue for the importance of understanding depression in adolescence from a multilevel or ecological framework.

The Korea Research Institute of Standards and Science (KRISS) has three major vacuum systems: an ultrasonic interferometer manometer (UIM; Section II, Figs. 1 and 2) for a low vacuum, a static expansion system (SES; Section III, Figs. 3 and 4) for a medium vacuum, and an orifice-type dynamic expansion system (DES, Section IV, Figs. 5 and 6) for high and ultra-high vacuum systems. For each system, explicit measurement model equations with multiple variables are given. According to ISO standards, all of these system variable errors were used to calculate the expanded uncertainty (U). For each system, the expanded uncertainties (k = 1, confidence level = 95%) and relative expanded uncertainty (expanded uncertainty/generated pressure) levels are summarized in Table 4. Within the uncertainty limits, our bilateral and key comparisons [CCM.P-K4 (10 Pa to 1 kPa)] are extensive and in good agreement with those of other nations (Fig. 8 and Table 5).

Titanium nitride and related overlayers produced by arc ion plating (AIP) are applied as commercial coatings in world-wide scale since the middle of 80s. Due to the achievements of low temperature deposition (LTD), they begin now to be used as wear and corrosion-resistant coatings for machine parts, besides applications on cemented carbide and high speed steel cutting tools. On the other side, TiN can be now applied successfully to brass, Al-alloy, ZnAl alloy articles as decorative coating through LTD. Various nitrides, carbonitrides, borides and other refractory compounds, such as (Ti, Al)N, TiCN, CrN, are used as the coatings for special heavy-duty working conditions instead of TiN since 90s. More and more multilayer coatings are applied now substituting single layer ones. Duplex processes are under development.
