In order to assess the relative importance of providing rural life services for the sustainability of rural communities and determine their prioritization, this study employed Analytic Hierarchy Process (AHP) to derive the relative importance of sectors and items in the realm of life services influencing the quality of rural life. A survey was conducted with three groups of experts. Group I consisted of experts in rural life services and rural environmental research (22 individuals), Group II included government officials responsible for implementing rural agreements in pilot areas (18 individuals), and Group III comprised executives from the Rural Life Improvement Association and 4-H organization working towards improving rural life and society (20 individuals). The analysis results revealed the following facilities as top priority in their respective categories: ‘National and Public Childcare Centers’ for ‘Childcare,’ Elementary and Middle Schools for ‘Education,’ Senior Welfare Facilities for ‘Welfare,’ Cultural Centers and Local Cultural Facilities for ‘Culture,’ Public Sports Facilities for ‘Sports,’ Emergency Medical Services for ‘Healthcare,’ Commercial Facilities in daily routines for ‘Commercial and Residential Services,’ Emergency Safety Agencies for ‘Administration and Security,’ and rural village Shelter for ‘Leisure and Rest.'

The aim of this study was to determine the therapeutic effects of beauty care on negative mental health, including stress and depression. Nail care, massage care, and makeup were used as programs for beauty therapy. Qualitative research was conducted with six female participants over five-month period. After interviewing the subjects in advance, beauty care treatments were performed every week 4 weeks in the following order: nail care, massage, and makeup. The results are as follows, First, the participants perceived beauty care in the form of 4 concepts: “courtesy in social life,” “investment in oneself,” “self-satisfaction,” and “self-care.” Second, the effects of beauty therapy were categorized as “psychological effects,” “confidence,” “behavioral changes,” “evaluation of others,” and “positive social effects.” Third, each subject showed different psychological effects during the process when the function of the therapy took effect through the beauty care treatment. It was confirmed that confidence levels increased as a result of treatment through the process of becoming re-aware of oneself. Positive statements from the participants included: “I want to go out,” “I have become kind and positive to others,” “I have become more active in a given task,” and “It seems that my work ability is improving.” Finally, t-test results for selfesteem, depression, and stress showed there were significant differences in self-esteem and depression. This confirmed that self- esteem increased, and depression decreased after the beauty care treatment.

Demethoxycurcumin (DMC), which is a curcuminoid found in turmeric, has anti-proliferative effects on cancer cells. However, the effect of DMC on osteosarcoma has not been established. The aim of this study was to examine the effects of DMC on cell growth and apoptosis induction in MG-63 human osteosarcoma cells. This study was investigated using 3-[4, 5-dimethylthiazol-2-yl]-2, 5 diphenyl tetrazolium bromid assay, Live/Dead cell assay, 4’, 6-diamidino-2-phenylindole staining, and immunoblotting in MG-63 cells. DMC induced MG-63 cell death in a dosedependent manner, with an estimated IC50 value of 54.4 μM. DMC treatment resulted in nuclear condensation in MG-63 cells. DMC-induced apoptosis in MG-63 cells was mediated by the expression of Fas and activation of caspase-8, caspase-3, and poly (ADP-ribose) polymerase. Immunoblotting results showed that Bcl-2 and Bcl-xL were downregulated, while Bax and Bad were upregulated by DMC in MG-63 cells. These results indicated that DMC inhibits cell proliferation and induces apoptotic cell death in MG-63 human osteosarcoma cells via the death receptormediated extrinsic apoptotic pathway and mitochondria-mediated intrinsic apoptotic pathway.

Alpha-lipoic acid (ALA) is a naturally occurring antioxidant and has been previously used to treat diabetes and cardiovascular disease. However, the autophagy effects of ALA against oxidative stress-induced dopaminergic neuronal cell injury remain unclear. The aim of this study was to investigate the role of ALA in autophagy and apoptosis against oxidative stress in the SH-SY5Y human dopaminergic neuronal cell line. We examined SH-SY5Y phenotypes using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay (cell viability/proliferation), 4′,6-diamidino-2-phenylindole dihydrochloride nuclear staining, Live/Dead cell assay, cellular reactive oxygen species (ROS) assay, immunoblotting, and immunocytochemistry. Our data showed ALA attenuated hydrogen peroxide (H2O2)-induced ROS generation and cell death. ALA effectively suppressed Bax up-regulation and Bcl-2 and BclxL down-regulation. Furthermore, ALA increased the expression of the antioxidant enzyme, heme oxygenase-1. Moreover, the expression of Beclin-1 and LC-3 autophagy biomarkers was decreased by ALA in our cell model. Combined, these data suggest ALA protects human dopaminergic neuronal cells against H2O2-induced cell injury by inhibiting autophagy and apoptosis.

본 연구는 원통형 종이포트 토마토 육묘시 Diniconazole의 처리방법이 도장억제 및 근권발달에 미치는 영향을 검토하기 위하여 수행되었다. 그 결과, 엽면적, LAR, 초장, 충실도, 생체중, RGR 및 R/S 에서 시험구간 유의한 차이를 보였다. 동일한 농도를 처리했을 경우, 근권부와 지상부의 흡수도 차이로 인해 저면관수가 엽면살포에 비해 도장억제에 효과적이었다. 저면관수는 엽면시비의 10분의 1의 농도만으로도, 20~30%정도의 동일한 도장억제 효과를 얻을 수 있었다. 디니코나졸 처리에의한 근권부 반응이 흥미로웠는데, 저면관수시 총근장, 근권부피, 평균 근경 및 근단수가 증가하였다. 특히, 0.3mm 이하의 초미세근이 감소하고 0.3~0.6mm의 세근이 증가하였다. 따라서 원통형 종이포트 육묘시 저면관수를 하는 것이 기존 엽면시비에 비해 사용량이 적으면서도 도장억제 및 근권부 활착률을 높힐 수 있을 것으로 판단된다.

Acacetin, which is present in damiana (Turnera diffusa ) and black locust (Robinia pseudoacacia ), has several pharmacologic activities such as antioxidant, anti-inflammatory, and anti-proliferative effects on cancer cells. However, the effect of acacetin on head and neck cancers has not been clearly established. This study aimed to examine the effects of acacetin on cell growth and apoptosis induction in FaDu human pharyngeal carcinoma cells. These were investigated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, Live/Dead cell assay, 4′,6-diamidino-2-phenylindole dihydrochloride staining, caspase-3 and caspase-7 activation assay, and immunoblotting in FaDu cells. Acacetin induced FaDu cell death in a dose-dependent manner, with an estimated IC50 value of 41.9 µM, without affecting the viability of L-929 mouse fibroblasts as normal cells. Acacetin treatment resulted in nuclear condensation in the FaDu cells. It promoted the proteolytic cleavage of procaspase-3, -7, -8, and -9 with increasing amounts of the cleaved caspase isoforms in FaDu cells. Acacetin-induced apoptosis in FaDu cells was mediated by the expression of Fas and activation of caspase-8, caspase-3, and poly (ADP-ribose) polymerase. Immunoblotting showed downregulation of the anti-apoptotic mitochondrial proteins Bcl-2 and Bcl-xL, but upregulation of the mitochondria-dependent pro-apoptotic proteins Bax and Badin FaDu cells after acacetin treatment. These findings indicate that acacetin inhibits cell proliferation and induces apoptotic cell death in FaDu human pharyngeal carcinoma cells via both the death receptor-mediated extrinsic apoptotic pathway and the mitochondria-mediated intrinsic apoptotic pathway.

Consumers’ desire for beauty has become a driving force in the beauty service industry which was further developed through specialization and segmentation. Nail-care service, which is one of the beauty services, is showing rapid growth, and intense competition among salons has become apparent. Thus, service management method and marketing strategy are required for customer satisfaction. Therefore, in this study, we tried to classify the nail-care services on the basis of systematization and realization of its characteristics which are fundamental when developing management and marketing strategies. The subjects of this study were women in their 20s and above living in Seoul, Gyeonggi, and Incheon areas. As a result, the nail-care service factors are classified as “external environment” (interior, celebrity, newness), “internal environment” (equipment and products, cleanliness, and environment), “location” (location and transportation convenience), “reputation” (good reputation), “technician skill,” “kindness,” “relationship” (relationship, empathy, and affinity), and “price and discount.” The consumer types of nail-care services were classified into three groups according to the degree of involvement of these concept systems. These results can be used as marketing basics and will be the basis for studying marketing strategies. However, the consideration of setting up a marketing strategy for each consumer type will be presented in a follow-up study.

Resveratrol (3,4',5,-trihydroxystilbene), a phytoalexin present in grapes, exerts a variety of actions to reduce superoxides, prevents diabetes mellitus, and inhibits inflammation. Resveratrol acts as a chemo-preventive agent and induces apoptotic cell death in various cancer cells. However, the role of resveratrol in odontoblastic cell differentiation is unclear. In this study, the effect of resveratrol on regulating odontoblast differentiation was examined in MDPC-23 mouse odontoblastic cells derived from mouse dental papilla cells. Resveratrol significantly accelerated mineralization as compared with the control culture in differentiation of MDPC-23 cells. Resveratrol significantly increased expression of ALP mRNA as compared with the control in differentiation of MDPC-23 cells. Resveratrol significantly accelerated expression of ColⅠmRNA as compared with the control in differentiation of MDPC-23 cells. Resveratrol significantly increased expressions of DSPP and DMP-1 mRNAs as compared with the control in differentiation of MDPC-23 cells. Treatment of resveratrol did not significantly affect cell proliferation in MDPC-23 cells. Results suggest resveratrol facilitates odontoblast differentiation and mineralization in differentiation of MDPC-23 cells, and may have potential properties for development and clinical application of dentin regeneration materials.

Nail-care services are growing rapidly. If causes for the increase in nail-care service consumption is diversion or self-satisfaction, we can speculate that consumers perform self-care through nail-care services. Nail-care-service consumption should be allowed to increase because of the positive psychological effects such as improving mood or alleviating depressed emotions. Moreover, the psychological effects of nail-care services differ according to consumers’ tendencies. Therefore, this study divides the types of consumers, to investigate whether there is a difference in the psychological effects of nail-care services depending on the types. This study used the questionnaire survey method. Results of the study revealed that the sub-factors of self-esteem, extracted as two factors, were “personal self-esteem” and “social self-esteem”. Consumers were classified according to the sub-factors of self-esteem into four groups. There were differences in the psychological effects of nail-care services according to these four groups. It was found that all groups had psychological effects above the average value. This result indicates that only the degrees of psychological effects differ in accordance with the types of self-esteem, and that psychological effects generally play a large role in all types. Since psychological effects were positive for everyone regardless of their self-esteem, utilizing nail-care services considerably reduces the depression and anxiety of modern people. Nail-care services expected to become the basis of the nail therapy field.

Fumigation activity of Frankliniella occidentalis, western flower thrips, and phytotoxicity were evaluated with phosphine(PH3) and ethyl formate (EF) in the asparagus. Fumigation activity of PH3 and EF showed in the order of egg (64.7 mg·h/Land 132.9 mg·h/L), nymph (5.5 mg·h/L and 14.8 mg·h/L), and adult (3.8 mg·h/L and 14.7 mg·h/L) respectively at 5˚C in12 L desiccator. The adsorption of PH3 was 24% at 5˚C. However, the adsorption of EF increased sharply to 98% at 5˚C.PH3 showed 100% control for all development stage of F. occidentalis with 4g/m3 in 0.65m3 at 2˚C for 48h exposure. Thephytotoxicity was not found. The results revealed that the EF is highly absorbable in asparagus, so it is not suitable as afumigant, but PH3 is considered to be suitable as an alternative MB fumigant for control of the F. occidentalis in asparagus.

Ethyl formate (EF) and phosphine (PH3) is an alternative fumigant to methyl bromide (MB). For applying import sweet pumpkins in Korea, the efficacy of EF and PH3 was evaluated on Tetranychus urticae adult and egg stage which is pest in sweet pumpkins. The eggs of T. urticae were more tolerance than adults in both EF and PH3. When T. urticae eggs were treated with EF for 4 hrs, LCT99=107.63 mg/L and LCT99=45.37 mg/L at 5°C and 20°C, respectively. PH3 treatment at 5°C and 20°C for 24 hrs, eggs were controlled LCT99=49.44 mg/L and LCT99=17.23 mg/L, respectively. The mixed treatment of EF and PH3 showed no significant synergistic effect on T. urticae. However, EF (80 mg/L) and PH3 (4 mg/L) treatment did not cause any external phytotoxicity damages in sweet pumpkin even when treated with the maximum amount of fumigant at 5℃ and 20℃ for 24hrs.

Ethyl formate (EF) and phosphine (PH3) is an alternative fumigant to methyl bromide (MB). The egg, nymph, and adult stages of Frankliniella occidentalis in asparagus were examined for the fumigation activity of EF and PH3. The eggs of F. occidentalis were more tolerance than other stages (adults and nymphs) in both EF and PH3. When the EF was treated for 4 hrs at 5℃ and 20℃, the eggs of F. occidentalis were LCT99=98.70 mg/L and LCT99=61.13 mg/L, and adults were LCT99=11.50 mg/L and LCT99=3.18 mg/L, respectively. However, at 5℃ and 20℃, the eggs were LCT99=83.76 mg/L and LCT99=53.6 mg/L, and adults were LCT99=4.58 mg/L and LCT99=3.44 mg/L, respectively for 4 hrs treatment of PH3. The PH3 was not any external phytotoxic damages at the maximum dose (4 mg/L), but the EF caused significant phytotoxicity in asparagus.

This study investigated the antidiabetic effect of amaranth grain ethanol extract (AEE) in a diabetic animal model, db/db mouse. The mice were divided into 4 groups: normal control mice (C57BL/6J), diabetic mice (C57BL/6J db/db), diabetic mice fed a lower concentration of AEE (0.3 mg/kg), and diabetic mice fed a higher concentration of AEE (0.5 mg/kg). After 10 weeks of treatment, body weights, blood insulin levels and blood glucose levels of each group were compared. At the end of treatment, the results showed that both AEE supplemented groups had lower body weights than those in the diabetic groups although higher than those in the normal groups. Moreover, in both AEE supplemented groups, serum insulin levels were higher and blood glucose levels were lower than those in the diabetic groups although both values were higher than those in the normal groups. The results of this study suggest that AEE can alleviate many of the common symptoms of diabetes in diabetic mice and, therefore, has potential as a therapeutic supplement for normalization of blood glucose and insulin levels in humans.
