This study investigated the effectiveness of the assessment of psychosocial treatment outcome in symptomatology and social functioning as rated by the depressed client's significant other in explaining the client's symptomatology and social adjustment at 6 and 12 month follow-up period after the 16-week psychosocial treatment was terminated. The data were drawn from the National Institute of Mental Health Treatment of Depression Collaborative Research Program of the U.S. Significant others of depressed clients have rarely participated in the assessment of treatment outcome, although they are major participants of the clients' daily life and have meaningful opportunities to observe the clients' functioning in different social situations. Thus, this study aimed to examine the explanatory power of the significant others' outcome assessment in depressive symptomatology and social functioning for the long-term outcome in symptomatology and social adjustment. The outcome measures used by the significant others were actual performance, expected performance, gap between actual and expected performance, and symptomatology drawn from the Katz Adjustment Scale-Relatives Form. Three major findings were: (1) in general, the posttreatment assessment by the significant other demonstrated stronger explanatory power of the follow-up status than the assessment rated at pretreatment in all of the four outcome domains; (2) the significant other's assessment of actual and expected performance at both pre- and posttreatment demonstrated significant explanatory power of the follow-up status in symptomatology and social/leisure and work adjustment; and (3) the significant other's assessment of social functioning at pretreatment improved the explanatory power over and above the explanation by symptomatology in the follow-up status of social/leisure and work adjustment; however, at posttreatment, symptomatology improved the explanation over and above social functioning more frequently in predicting both symptomatology and social/leisure and work adjustment. These findings suggest the effectiveness of the measures of symptomatology and actual and expected performance as assessed by significant others. The results imply that mental health professionals and researchers need to involve the depressed client's significant other in the treatment and make good use of their contribution in treatment planning and further intervention in the follow-up period to prevent relapse.

The purpose of this study was to investigate nutrient intake status and dietary behaviors in elementary school children. The subjects were 98 boys and girls in the 4~6 grade and divided into three groups by body shape. The protein intakes of the subjects were higher than the Korean EER (estimated energy requirements). Especially male over weight group had more than twice intakes (216.0% ) comparing the Korean EER. The mean daily intakes of calcium, iron, vitamin A and vitamin C in all subjects did not meet the Korean RI (recommended intake). The vitamin C intake of male underweight group was only 43.2% comparing the Korean RI. Rice & cereals were main food sources of energy, protein and iron, and milk & milk products were main food sources of calcium. As their weights were high, the meal volume and the rate of skipped meal were shown to be high (p<0.05). Thus, this study implicates that desirable nutrition education may be needed for overweight and underweigh children.

This study was to investigate the level of knowledge, recognition, behavior of radiographic safety control and job stress in dental hygienists and to determine the relationship among variables. The subjects were 256(56.9%), who were worked in dental hospital and clinic with mean age of $29.59{\pm}7.30$. Data was collected using a self administrated questionnaire from April 4 to May 15, 2010. Behavior of radiographic safety control was measured using the 15-items and job stress was measured using the 5-items with 5-point likert scale. The data were analyzed with t-test, one-way ANOVA and pearson correlation coefficient using the SPSS WIN 17.0 program. Regarding job stress, the subjects was a mean of 2.63 out of a maximum 5 points. The level of knowledge, recognition, behavior of radiographic safety control a mean of 3.11, 4.08 and 3.43 out of a maximum 5 points. Recognition and behavior of radiographic safety control was negative related job stress in this study. Based on the findings, behavior of radiographic safety control is associated with job stress. These results suggest that various program should be considered for radiation safety control of dental hygienists.

World production of mushrooms has been increasing 10-20% every year. Recently, Pleurotus eryngii and P. nebrodensis are very popular as new mushroom species for cultivation. Two kinds of mushrooms, Gumji (Ganoderma) and Soji, were described in old book of Samguksagi (History of the three kingdoms; 1145) in Koryo-dynasty. Many kinds of mushrooms were also described in more than 16 kinds of old books during Chosun-dynasty in Korea. One hundred and sixty commercial strains of 25 species in mushrooms were distributed to cultivators. By the way, only 8 varieties of them have registered variety protection. Mushroom industry as important export products developed from 1960 to 1980. Production of mushrooms as food was 181,828 metric tons valued at 800 billion Korean won in 2003. Isolated and identified substances from mushrooms are promising antifungal, antiinflammatory, antitumor, antiviral (anti-HIV), antibacterial & antiparasitic, antidiabetic, immunomodulating, kidney tonic, hepatoprotective, nerve tonic, and sexual potentiator. These substances can also be used for blood pressure regulation and effective against cardiovascular disorders, hypocholesterolemia & hyperlipidemia, and chronicbronchitis. Mushroom products including pharmaceuticals, tonics, healthy beverages, functional biotransformants, and processed foods have also became available on the markets. Compost and feed can likewise be made from mushroom substrates after harvest. The mushroom industry is already one of the fastest growing investment sectors in Korea. By the way, there is a need to strain improvement for variety protection, advanced cultivation technology at low cost for growers, and control of demand and supply for marketing in order to more upgrade development of mushroom industry in the future.

Skin wrinkles are associated with collagen synthesis and matrix metalloproteinase-I (MMP-1) activity. This study was carried out to select optimum ratio of 3 herbs in skin health food for anti-wrinkle. Human dermal fibroblast cell was incubated with experimental samples, which were Korean red ginseng ethanol extracts (ER), Torilis fructus water extracts (WT), Corni fructus water extracts (WC) and their mixtures (WM1, WM3). And then we determined effects on collagen biosynthesis, MMP-1 activity and SOD activity in human dermal fibroblast cell. In control group, collagen biosynthesis was amounted at 474.8 ng/ml and 533.9 ng/ml, 539.3 ng/ml, 514.1 ng/ml in ER, WT and WC respectively. Furthermore, WM3 (KTNG0345) was increased to 561.45 ng/ml. MMP-1 activity of ER, WT, WC, WM1 were determined to 31.9 ng/ml, 32.85 ng/ml, 32.0 ng/ml, 31.3 ng/ml and WM3 (KTNG0345) was decreased to 28.85 ng/ml. In addition, the experimental samples showed a antioxidative activities. From this results, we conclude that Korean red ginseng ethanol extracts, Torilis fructus water extracts, Corni fructus water extracts and their mixtures have a anti-wrinkle effect and WM3 (KTNG0345) may be regarded as an optimum composition for synergic effect producing. The standardized components of KTNG0345, ginsenoside-$Rb_1$, torilin and loganin were identified at 10.85 mg/g, 0.128 mg/g and 3.92 mg/g respectively.

The purpose of this research is to distinguish the quantitative determination of phytochemicals in various agricultural products and to optimize an HPLC method for the determination of lycopene, lutein, ${\alpha}$-carotene, ${\beta}$-carotene, and cryptoxanthin. Among the different conditions studied, the most suitable ones for our samples were the extraction with hexane/acetone/ethanol (50:25:25, v/v/v), dissolution of the dry extract in tetrahydrofuran/acetonitrile/methanol (15:30:55, v/v/v), injection on a $C_{18}$ column with methanol/acetonitrile (90:10, v/v) + triethylamine $9{\mu}M$ as mobile phase, and ${\lambda}_{detection}$=475 nm. The mean percent recovery for the HPLC method were $120.7{\pm}4.1%$ (lycopene), $89.2{\pm}3.5%$ (lutein), $91.2{\pm}2.9%$ (${\alpha}$-carotene), $99.1{\pm}4.4%$ (${\beta}$-carotene), and $100.0{\pm}5.3%$ (cryptoxanthin). The contents of lutein in the agricultural products were spinach, kiwi, tomato, blueberry, melon, respectively. However, the lycopene contents were the highest in the Black tomato ($56.66{\pm}7.48mg/kg$) and Jangseong tomato ($50.28{\pm}5.42mg/kg$). The concentration of ${\beta}$-carotene in all of the agricultural products ranged from 0.07 mg/kg to 65.03 mg/kg. The quercetin content of the agricultural products increased in the order of blueberry (986.57~1,054.06 mg/100 g), kiwi (44.96~55.09 mg/100 g), hallabong (31.92~35.60 mg/100 g), and tomato (26.38~34.94 mg/100 g). The highest kaempferol content was found in the blueberry (47.79~76.15 mg/100 g) with results in all of the tested samples varying between 6.54~48.11 mg/100 g. The total polyphenol contents of the various agricultural products increased in the blueberry (213.60~229.96 mg/100 g), spinach (112.50~141.67 mg/100 g) and kiwi (46.49~70.44 mg/100 g). The total flavonoid content was the highest in both blueberry and spinach. Vitamin C content was detected in kiwi > hallabong > tomato > blueberry, respectively. The total anthocyanin contents (TAC) was detected in the Damyang blueberry and the imported blueberry.

Objectives: The development of internet programs for smoking cessation was motivated to quit smoking in the large group of smokers. This personalized program consisted of tailored message to consider the smokers characteristics, and contain the informations on the outcomes of smoking cessation and the skills to be used in the quit attempts. The purpose of this study was to develop the internet management program and information push-delivery system for smoking cessation to encourage the personal intention to quit smoking. Methods: We conducted in 3 steps as developing push service to encourage intention of smoking cessation, analyzing problems of smoking cessation program through the pilot test and suggesting improvements by implication stages. Results: This program is delivered for 30 days. if the participants do not fail to quit smoking. The contents consisted of 13 stages which were divided on starting period. practical period, maintenance period and success period. And push service afforded the tailored message to participants using their e-mail. According to the evaluation of pilot test, the problems of internet information push-delivery service for smoking cessation were the over-tasks per visiting time, recording style of participants, difficulty of terms and sentences, lack of visual effects, absence of follow-up module and unsuitable link with main homepage. Improvements were divided on 3 stages by implication period. The first stage included the immediate improvements as improving link with homepage, modifying menu of smoking information and upload file of notice part. The second stage included the short term improvements as alleviating condition of withdrawal, coordinating start stage of retrial, modifying errors of information push-delivery service and addition of educational materials. The third stage included the long term improvements as development of follow-up module, cost-effectiveness evaluation, reducing contents quantity, introduction of checking style, compensation of graphics effect and review for SMS utilization. Conclusions: This program contribute to improving smoking cessation rate. Therefore this program should be tested in a community to evaluate the effectiveness. To promote the effectiveness, this program should be developed the contents and the strategies for various targets, and established the follow-up system for ex-smokers.

Statement of problem: Restoring and replacing teeth with fixed prostheses commonly used in dental practice. Because of improper oral hygiene care and inaccurate laboratory procedure, complications of fixed prostheses were found in the mouth of patients. Although many efforts have been continually made to obtain the data of long term prognosis of fixed prostheses, it was difficult to do it. Purpose: The purpose of this study was to evaluate the clinical status of fixed prostheses. Material and methods: In order to assess the clinical status of fixed prostheses, a total of 161 individuals(aged 17-85, 99 women and 62 men with 1596 unit of fixed prostheses, and 1169 abutments) who first visited the Department of Prosthodontics, Pusan National University Hospital, between April to September, in 2007 were examined. Results and conclusion: The results of this study were as follows: 1. Length of service of fixed prostheses was $8.6{\pm}0.6$ years(mean), 10.0 years(median). 2. Location of fixed prostheses was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in posterior region and in mandible where the failure rate was high in combination(P<.05). 3. Longevity of fixed prostheses made of metal was longest(mean: $13.0{\pm}9.3$, median: 14.0), gold, precious ceramic, non-precious ceramic trailing behind(P<.05). 4. Number of units in fixed prostheses was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in Single-unit and the failure rate was high in over 3-unit(P<.05). 5. Condition of opposing dentition was found to have no statistically significant influence on longevity of fixed prostheses(P>.05). But, the success rate was high in natural dentition(P<.05). 6. Defective margin(28.2%), dental caries(23.0%), periodontal disease(19.3%), periapical disease(16.9%) were frequent complications. In 30.1% of the cases, abutment state after removing fixed prostheses was needed to be extracted.

This study investigated the anti-inflammatory activity of barley leaf extract in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and hairless mice. Pre-treatment with barley leaf extract significantly inhibited the protein expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-II (COX-II) in a dose-dependent manner in LPS-stimulated RAW264.7 cells. Barley leaf extract also significantly inhibited the secretion of inflammatory cytokines, such as tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), and interleukin-6 (IL-6). Moreover, phosphorylation of mitogen-activated protein kinases (MAPKs) and nuclear translocation of nuclear factor-kappa B (NF-${\kappa}B$) were strongly suppressed by barley leaf extract in LPS-stimulated cells. In hairless mice, barley extract significantly decreased the pathological phenotypes of contact dermatitis, such as erythema, edema, and scabs. These results indicate that barley leaf extract has an anti-inflammatory effect and therefore a possible role in the treatment of inflammatory diseases or in functional cosmetics.

The purpose of this study was to investigate food involvement, dietary behavior and relationship according to the levels of nutrition knowledge. Data in this research was obtained by using the questionnaire which was given out to 528 subjects(boys 182, girls 346) in Naju city area. The awareness of dietary behavior of middle school students put the first priority on breakfast from among 3 meals a day, and they selected 'taste' as the most important criterion. The majority and above of subjects responded that they had ever delivered food at least more than 1 or 2 times a week. This research found that middle school students are tends to regard themselves as being rather close to obesity or fatness. Subjects were also aware that they have some problems with a unbalanced eating habbit and irregular timing of having meals, and more than 40% of the subjects responded that they obtain the most of information about food & dietary behavior through television. Significant difference was found in the food involvement with related variables such as sex, grade, the academic background of mother, self-perception of weight, the way of weight control, perception of problems requiring improvement. Dietary behavior related with variables showed significant difference. Variables are grade, perception of meal importance, selecting standard of food, method of weight control, improvement of eating habits. Dietary behavior is found highly relative with food involvement. Dietary behavior is found highly relative with food involvement. In conclusion, suggestions that could bring motivation to improvement is more essential to the nutrition education rather than knowledge oriented education.
