The present study conducted to examine the effects of proteins from different sources on Ca excretion in 6 healthy young adult Korean women. The subjects were given meat protein diet for 5 days and soy protein diet for subsequent 5 days. the two diets were similar in protein and Ca contents. Urinary and fecal samples were collected for the last 2 days of each diet period and were analyzed for Ca and P. The results were as following ; 1) Mean daily urinary calcium excretion was 126.5$\pm$22.70mg for meat protein diet and 83.7$\pm$17.19mg for soy protein diet and the difference was significant (P<0.025). 2) Fecal Ca excretion did not show significant difference between two experimental preiod ; 466.9$\pm$73.68 mg of meat portein diet 284.4$\pm$54.96mg for soy protein diet. 3) Three out of six subjects showed negative balance on meat protein diet, but only one showed negative balance on soy protein diet. The averageof the balances on meat protein diet was -65.4 $\pm$68.19 and that of soy protein diet was 155.3$\pm$52.28 ; the difference was significant(P<0.025). 4) Urinary P excretion tended to be higher on meat protein diet but was not significant compared to soy protein diet . Fecal P excretion was significantly higher (P<0.001) on soy protein diet. Overall P balances for meat protein diet and soy protein diet were 219.94 mg and 229.46mg respectively (P<0.05). The above results show that urinary Ca excretion was significantly higher on meat protein diet but fecal excretion did not show significant difference between meat protein diet and soy protein diet. The overall Ca balance was significantly higher on Soy protein diet compared to meat protein diet.

The purpose of the study focuses on the agriculture education services in the changing rural areas conditions such as population decline, aging society, and returning farmers. The study reviews the effects of agricultural education services on returning farmers and local residents for satisfaction, intention for recommendation, and intention to continue participation. Further, the study aims to investigate any difference in the level of satisfaction for two groups. The results suggested that there is a meaningful difference between return-farmers and local residents. Among the demographic variables, age and income showed a notable difference. However, sex, level of education and type of household did not suggest noticeable differences. In addition, the study accessed agricultural education from a service perspective and analyzed its service quality and customer satisfaction, loyalty and relationship using a service profit chain model. Like the result of most other studies, the analysis showed that these had positive relationships. While the study focused on the efficiency of agriculture education training program in agriculture technology centers, the study carries a meaningful value in that it discovered a meaningful difference in the satisfaction level between returning farmers and locals despite the fact that agriculture education was applied as a part of service. In practical terms, the study pointed out the need for consumer-centered education that reflects the characteristics of the groups rather than standardized education.

The objective of this study was to confirm the validity of classification of dental disability by measuring the dental treatment time required for disabled patients and identify the disability type that requires more of chair time. As a result of measuring a total of 123 patients who were admitted to the Seoul dental hospital for the disabled on Oct. 2014, I was able to make the following conclusions: 1. For dental counseling and check-up, the chair time did not show significant differences between the different types of disability. 2. For periodontal treatment, restorative treatment, root canal treatment, and surgical treatment, the difference of the chair time for dentally disabled patients was significantly longer than that of non-dentally disabled patients. 3. The difference in the total chair time for prosthetic treatment was statistically insignificant. However, each of the prosthetic treatment steps did show statistically significant differences.

This is a study of care-oriented morality and justice-oriented morality among middle-aged adults. Thirty seven males and forty six females between the ages of 45 and 59 years old participated in this study Care-oriented morality was measured by the Ethic of Care Interview(ECI) while the justice-oriented morality was assessed using the Korean Defining Issues Test(DIT). Sex role identification was interpreted by using the Korean Sex Role Inventory(KSRI). In terms of care-oriented morality, the majority of the subjects were at level 2. The P(%) score of justice-oriented morality was found to be a little low. We found a significant difference between genders in terms of care-oriented morality, with females exhibiting a higher care-oriented morality. However, there was no significant difference in sex role identity types in terms of care-oriented morality. Nor did we find a significant interaction effect between gender and sex role identity. There was no gender difference in justice-oriented morality, but there was a significant difference among sex role identity types. Masculine males Possess the highest justice-oriented morality. A significant interaction effect was found to exist between sex role identity and gender.

Purpose: The purpose of this study was to demonstrate the effects of visiting nursing services in long-term care (LTC) insurance on changes in health status and physical functions among the elderly. Methods: We analyzed survey data on the living status and welfare needs of the elderly from 2008 and 2011 using the difference-in-difference method with propensity score matching. Results: The subjects were 76 elders including 38 visiting nursing service users(intervention group) and 38 home-based LTC service users (control group). Results from DID analysis confirmed that the subjective health status level of the intervention group was 2.2 points higher (p=.044) and the depression level was 0.3 point lower (p=.039) than the control group. In addition, the intervention group's ADL score was 1.9 (p=.027) and IADL 3.9 (p=.030), showing that their health was deteriorated less. Conclusion: Visiting nursing service in LTC insurance was associated with delayed deterioration of subjective health status, depression, ADL and IADL. These findings suggest the need of rebuilding visiting nursing service programs focusing on prevention services, which will be more contributive to elderly health care and the reduction of social costs.

This study was conducted to investigate methods to overcome serious problems in hedge making. The growth response of Enonymus japonica was investigated, using different sizes of nonwoven fabric containers. Changes of shoot length, fresh weight and chlorophyll contents were measured a period of growth in each size of container. The results of this study are as follows; 1) The maximum growth of shoot length in all treatments was observed in May and August. The significant difference was found in the smaller size of container containing a less amount of soil than the control. 2) The soil amount of rhizosphere for the production of a standardized hedge seemed to be over 2,400-3,600㎤ per plant. 3) The depth of containers had a greater influence on growth of shoot length than the width of containers. 4) The fresh weight in 40cm width containers and 30$\times$20cm containers was similar to the control, but the rest of the containers showed significant difference compared with the control. 5) A significant difference of chlorophyll content was found in A, B, C, D and G treatment but I treatment did not show significant difference at the 5% level.

Objective: Core training is a key exercise for conditioning and fitness programs, injury prevention, and more. This study aimed to find out the effect of adding dynamic core training, which is frequently prescribed in clinical practice, on dynamic balance and muscle activity compared to conventional static core training. Design: An experimental study Methods: This study is an experimental pilot study of prospective parallel design. Six healthy young adults were allocated to static core training group (SCG; crunch and plank) and blended group (BG; crunch, plank, and dead bug exercise) for two weeks to perform core training. Dynamic balance and muscle activity (erector spinae, rectus abdominis) were measured for all participants before and after core training. Results: All six healthy young adults enrolled completed the study. No significant difference was found before and after 6 sessions of core training in each group (P>0.05). Likewise, no significant difference was found in the results of the difference comparison between groups (P>0.05). Conclusions: In conclusion, in this experimental study, no difference was found when dynamic core training was added. Although the results before and after core training did not show improvement in dynamic balance and muscle activity, a randomized controlled trial is needed considering the results of previous studies and the limitations of this experimental study.

This study was carried out to analyze the surface color change according to the weathering time. The surface color of material was one of evaluation indexes in exposure experiment. For the purpose, accelerated weathering test was performed with wood. The weathering time level was composed with 0, 500, 1000, 1500 and 2000 hours and color difference was estimated with the color difference meter. The surface color was changed to 500 hours that lightness and redness were decreased and yellowness was increased. However it did not changed after 500 hours. It means that the surface color could be the evaluation index of deterioration of the wood but it means very little after certain time.

This study aimed to investigate the effect of repeated oral health education on the oral health of preschool children. This study classified the control group of children of 5~6 years of age where the oral health education was conducted one time, and the experiment group where the oral health education was conducted 4 times. The oral health conditions of each group and their risk of developing dental caries were also assessed. No significant difference was observed in the participants in terms of general characteristics, oral health conditions, risk of developing dental caries, and oral health behavior after oral health education. The two groups did not show a significant difference (p<0.001) in dental plaque index before and after oral health education, and showed a significant difference (p<0.001) according to the number of education sessions. Before oral health education, the participants in both groups were brushing their teeth incorrectly. However, after the third session, 56.7% of the participants in the experimental group and 9.4% in the control group used the correct method of tooth brushing. A significant difference was observed between the two groups (p<0.05). In addition, when the tooth-brushing time was compared, the two groups showed a significant difference (p<0.001), and a significant difference was observed in terms of the number of education sessions (p<0.05). In summary, repeated oral health education had significant influences on the dental plaque index, tooth-brushing method, brushing occlusal surfaces, and tooth-brushing time. Therefore, when oral health education is carried out, repeated oral health education in children is more effective than one-time oral health education as reflected in the changes in dental plaque index and oral health behavior. Moreover, oral health education is considered effective in changing the oral health behavior of children when conducted at least 3 times.
