This research aims to audit foodservice sanitation management practices and to assess microbiological quality of foods and their food contact environments in kindergartens. Sanitation auditing was conducted in 10 kindergartens in Seoul, Gyeonggi, and Incheon areas to assess the levels of safety practices. Results revealed that the surveyed kindergartens scored 41.4 out of 100 points, on average. The average scores of each category were 6.4/11 (58.1%) for facilities sanitation, 4.2/12 (35.0%) for equipment sanitation, 2.4/10 (24.0%) for personal hygiene, 5.1/10 (51.0%) for food ingredients management, 6.0/17 (35.3%) for production process, 5.4/10 (54.0%) for environmental sanitation, 2.0/6 (33.3%) for kitchen utensils sanitation, and 2.2/6 (96.7%) for safety management. Microbiological quality of raw, prepared foods, personal sanitation (hands), environmental sanitation, and drinking water were assessed. Total plate counts (TPC) of the following menus exceeded the critical limit: seasoned leek (5 log CFU/g), cucumber (5.0 log CFU/g), panbroiled fish paste (TNTC at $10^4$), tangpyeongchae (5.3 log CFU/g), egg rolls (6.1 log CFU/g), panbroiled sausage (TNTC at $10^4$), and soft tofu pot stew (TNTC at $10^4$). Coliform which exceeded the standard limit were detected from seasoned leek (2 log CFU/g), cucumber (2.5 log CFU/g), panbroiled fish paste (2.0 log CFU/g), egg roll (3.8 log CFU/g), tangpyeongchae (4.0 log CFU/g), panbroiled sausage (2.3 log CFU/g), and soft tofu pot stew (3.7 log CFU/g). For seasoned foods (muchim), S. aureus ranged 2.2~2.9 log CFU/g. In food workers' hands, microbial profiles ranged 3.8~7.9 log CFU/hand for TPC, ND~4.5 log CFU/hand for coliforms, ND~4.7 log CFU/hand for S. aureus, and ND~5.3 log CFU/hand for Enterobacteriaceae. Microbiological profiles of food contact surface of knives, cutting boards, dish-clothes, and trays showed possibilities of cross-contamination. General bacteria were 2.1~4.5 logCFU/ml in 4 purified water samples and E. coli were found in the kitchen of one kindergarten. These results suggested that environmental sanitation management practices need more strict improvement: effective sanitation education methods and practices were strongly required, and more strict sanitation management for cooking utensils and equipment were required.

This study aimed to provide directions and implications for a future program by analyzing studies on diabetes programs from 2000 to 2020. Among the studies with control and experimental groups, the selected studies included ones that provided intervention to patients with diabetes and ones that contained descriptive statistics. Sixteen studies were selected to verify the effectiveness and homogeneity of the data coding meta-analysis. The overall effect size in the diabetes program combined estimate was 0.398 (95% CI: 0.268, 0.425, p=0.000). Among the dependent variables, fasting blood glucose (-0.616) and glycated hemoglobin (-0.442) showed median effect sizes, but the effect of fasting blood glucose was not statistically significant. In terms of the study design, non-randomized control trials (NRCTs) (-0.543) was more effective than randomized control trials (RCTs) (0.719). Among, the counseling and self-management program (-3.241) showed a very large effect size. Furthermore, the cognitive-behavioral (-0.828) and self-management (-0.482) programs were also found to have a positive effect on lowering fasting blood glucose. As the importance of diabetes management increases, further studies based on RCT should be actively performed, and differentiated and specialized diabetes intervention plans need to be established.

The study was carried out to assess whether the nutritional management program by dietician at child center can affect nutritional status of children at child care center. The diet intakes were measured by mother\`s record at home and by direct weighing at child care centers, and the hight and weight of children were measured before and after nutritional management program for 3months to see the effects. The energy intakes were significantly increased 56.29 Kcal after program, and protein 3.61g, lipid 3.12 g, calcium 49.71mg, iron 0.39 mg, vitamin B$_1$ 0.084 mg, vitamin B$_2$ 0.116 mg, and vitamin C 10.10 mg, respectively, except vitamin A and niacin. the significant changes of nutrient intakes were more at higher age group compared to at the lower age group, and more at girls compared to boys, Although the significant increase fo nutrient intakes at child care center, most nutrient intakes at home were not significantly changed, except energy, lipid, iron, vitamin A. The changes at changes of fat and calcium intakes for 3 months were positively correlated to the change of Z-score for weight, and the change of A-score for weight was positively correlated to changes of Z-score for height. The results showed that the nutritional management program for 3 month at child care center can increase nutrient intakes significantly and the incresed nutrient intakes can enhance children\`s growth.

The aim of this study was to investigate the effects of aqueous extract from Sarcodon aspratus on tenderization of the bovine longissimus dorsi muscles in comparison with commercial proteolytic enzymes. Furthermore, meat quality and muscle protein degradation were examined. We marinated meat with 2% Sarcodon aspratus extract, 2% kiwi extract, and 0.2% papain. Beef chunks (3×3×3 cm³) were marinated with distilled water (control), Sarcodon aspratus extract (T1), kiwi extract (T2) or papain (T3) for 48 h at 4℃. There were no significant differences in muscle pH and lightness between control and treated samples. T1 had the lowest redness (p<0.01), and higher cooking loss and water holding capacity than control and T2 (p<0.05). T1 and T3 exhibited lower shear force values than control (p<0.05). Total protein solubility did not differ significantly between T1 and control, but T1 had less myofibrillar protein solubility than control and T2 (p<0.001). The degradation of myosin heavy chain in T1 and T3 was observed. This degradation of myofibrillar protein suggests that Sarcodon aspratus extract could influence tenderization. These results show that aqueous extract of Sarcodon aspratus extract actively affect the tenderness of the bovine longissimus dorsi muscle.

Monitoring or follow-up surveying pesticide residues in agricultural commodities is the key to meet the international regulations and to enhance international competitiveness of Korean agricultural commodities. Six neonicotinoid insecticides, acctamiprid, clothianidin, dinotefuran, imidacloprid, thiacloprid, and thiamethoxam were monitored in 95 paprika samples collected from Gyeongnam area. Thc pesticide residues were extracted by EN 15662 buffer based on the QuEChERS method, clean-upped with dispersive solid-phase extraction method to remove interfering pigments, and analyzed using UPLC-MS/MS. The neonicotinoid pesticides were detected in 90.5% of the paprika samples. Two or more pesticides were detected in 82.3% of samples. Although detection frequencies were high, all samples complied with the maximum residue limits (MRLs) set by both the Korea Food and Drug Administration (KFDA) and Japanese Ministry of Health, Labour and Welfare.

For the continuous growth of firms, the contributions of effective risk management system are required. This research analyzes the impact on the firm's performance related to risk management structure which includes the risk management system, risk management activity and risk management competency. In this research, the structural equation model considering the variable which contains enterprise risk management system, risk management activity and risk management competency was suggested. Also risk management organization and management procedures are identified as in enterprise risk management system. The implementation activity and control activity were the factors related in risk management activity. And risk management competency can be described as the response level of managing risk in outside and inside the firms' environment. Finally this model was analysed empirically for 112 firms in Korea using SPSS 18.0 and Amos 16.0. As the results, the suggested hypothesis were adopted. So as to manage risk performance for their firms, the development of systematic Risk Management Framework is important for their risk management activity and risk management competency. Ultimately, we can conclude that the focusing to the systematic risk management approach could be effective on the firm's risk management performance.

There's an opinion that it may be a combination of change of values and social economic factors that caused low fertility of Korean society. This study intends to analyze actual conditions of family children values and gender role centered on university students in a marriageable age so draw a policy implication for overcoming low fertility. Main findings of this study are like following. First, as for analysis of childbirth intention shows average score of $3.35{\pm}1.142$ presented sex distinction that men have a higher tendency to women. Second, in gender role attitudes, it shows that gender role related on women's social activities($2.06{\pm}0.739$), traditional gender role in family($2.41{\pm}0.789$) influence on childbirth intention (p<0.001). Third, in family children values indicates moderate scores($2.95{\pm}0.648$) that son's position in family ($2.33{\pm}0.911$), relation between children and parents($2.80{\pm}1.050$), individual's position in family($3.56{\pm}0.671$) influence on childbirth intention(p<0.000) in the traditional values. Measures against low fertility will prove effective when family values are established favorable to marriage, childbirth, rearing, gender equality is settled in a society as a whole and related systems.
