The purpose of this study was to verify the emotional response of user to LED light colors in healing bed system in cypress tree. Eight colors of LED light were provided including red, orange, yellow, green, blue, indigo, violet and white. And three illumination color temperature were provided including 3,000K, 5,000K, 8,000K. Seven subjects in their twenties were involved without the medical history of eyes and heart disorders. The subjects were exposed to LED lighting during 5 minutes and their emotional response was evaluated through the following: first, at the physiological effect heart rate variability(HRV) was measured during the stimulation; second, at the emotion level the subjects were asked about lighting color and color temperature through a survey. Results, lower color temperature of 3,000K and green color shows high value on HRV. We have found that there is a difference of physiological and emotion level effect depending on color stimulus. This study could be applied to reference data to analysis of a decrease in fatique and charges of brain waves for color stimulus.

Endothelin (ET) is a 21 amino acid peptide with multifunctional effects on the vasculature as well as a variety of other cell types such as respiratory, gastrointestinal, urogenital, endocrine, central nervous systems, and others. Endothelin has emerged as a modulator by autocrine and paracrine actions for many cellular activities, including vasoconstriction, cell proliferation, hormone production, neurotransmitter and/or neuromodulator. The endothelin family consists of three closely related peptides, ET-1, ET-2, and ET-3 derived from separate genes, such as chromosome 6, 1, and 20, respectively. ET-1 is the predominant isoform produced in the cardiovascular system and about which most is known. Endothelin receptors are seven-transmembrane GTP-binding protein-coupled receptors, which are classified into endothelin-A (ETA) and endothelin-B (ETB) receptors. Interestingly, recent evidence is accumulating to suggest that ET -1 may contribute to a variety of pain states such as allodynia and hyperalgesia in animals and humans. Therefore, in this review the biological characteristics and contraction-related mechanism of endothelin-1 in mammalian cells will be summarized. Especially, we focus on multifunctional roles for ET-1 in noxious stimulation-induced pain for the study of pain specialized physical therapy.

Currently, sexually transmitted diseases (STD) are referred to as "sexually transmitted infections" (STIs) in the sense of including asymptomatic infections. STIs have a range of interrelationships. This study used the STI defined by the Minister of Health and Welfare of the Republic of Korea, and targeted syphilis, gonorrhea, chlamydia infection, chancroid, genital herpes simplex, condyloma, human papillomavirus, and non-gonococcal urethritis. The factors were characterized by identifying multiple and simultaneous STIs. This study used the data from the laboratory information system of a consigned inspection institution located in Seoul from 2014 to 2019. In this study, multiple STIs were identified as overlapping STIs of a double infectious source (10 types) and multiple STIs of a third infectious source (6 types). Among the 16 types of multiple STIs, U. urealyticum (9 types), HSV-2 (8 types), C. trachomatis (7 types), HPV 6, 11 (7 types), N. gonorrhoeae (6 types), and T. pallidum (1 type) were included. Therefore, additional research on interrelationship studies, such as STIs, which has the highest proportion of multiple STIs, will be necessary.

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.

The purpose of this study was to explore the effects of perceived care-related burden and social support on life satisfaction and the moderating effect of social support from elderly spouses caring for their elderly partners with dementia. The subjects were 165 spouses aged over 60 years, caring for their elderly partners afflicted with dementia, and living in Seoul and Gyeonggi Province. The analysis results are as follows: First, the quantified total care-related burden shouldered by the participant spouses was 3.76 points (SD = .57), which was slightly higher than the median value. In the case of social support, informal support was scored 2.65 (SD = .78), and formal support was scored 2.60 (SD = .77), which was lower than the median value. Life satisfaction earned a score of 3.11 points (SD = .78), which somewhat exceeded the median. Second, subjective health status, income level, burden from social activity, and informal support influenced life satisfaction. Put differently, the higher the subjective health status of a caring spouse, the higher the income level, the lower the social activity burden, the stronger the informal support, and the greater the life satisfaction. Third, the interaction terms of social activity burden and informal support were significant. Therefore, informal support had a moderating effect on the relationship between social activity burden and life satisfaction among the elderly with dementia. In other words, even though the caring spouses experienced a burden from social activities, the higher the frequency with which they accessed informal support, the lower the decrease in life satisfaction.

Article 117, Paragraph 1 of the 「Constitution」 states that "Local governments may enact provisions relating to local autonomy, within the limit of Acts and subordinate statutes". It restricts the enactment of effective self-government laws. The fundamental problem-solving is securing the right to self-governing legislation through constitutional amendment. Therefore, it must be revised to "Local governments can make regulations on self-government to the extent that they handle resident welfare affairs in accordance with the subsidiarity and do not violate the law." In the long-term perspective, the current education council problem, which is contrary to the constitution, has to be revived as a constitutional independent education committee system, and the voting agency and the executive agency must go together and education councilors must have about 10 years of experience in education and education administration. The current superintendent's election system is of great significance in establishing democratic legitimacy by ensuring residents' right to vote and securing a superintendent's representation of residents. It hasn't been long since the system was implemented, but there are some side effects and it is argued that the election system should be replaced by the appointment by the head of the local government, the running mate system or the joint registration system. However it is thought that it is necessary to minimize and supplement the side effects rather than fixing the system as it violates the Constitution of the local education autonomy system.

While the local construction market has lost its steam in recent years, it is discussed that the overseas construction projects should be activated by using the Official Development Assistance (ODA) in terms of finding a new way. This study empirically identifies the relationship between ODA and the foreign construction orders, and discovers the effectiveness of orders for overseas construction projects using the ODA. Therefore, based on the past 25 years of time-series data on Asia, the VECM model was used to identify the relationship between the Asia country's ODA and construction orders. As a result, it has shown a lower-than-expected correlation between the value of ODA and the construction orders. There are several reasons for this; This is because profit-purpose construction projects and ODA for public welfare are fundamentally different, and the timing of ODA applications and overseas construction orders are different. Also, compared to other developed countries, Korea has far less experience and scale of ODA. At last, there are huge differences in the size of ODA and construction orders. In conclusion, although the effectiveness of overseas construction orders based on ODA was not clearly disclosed, the significance of this study is that it attempted to conduct a empirical study on the relationship between ODA and overseas construction orders. Further relationships are expected to be drawn through the accumulation of future ODA experience and the supplementation of time series data, which can provide on a theoretical and practical basis.

The purpose of this study is to examine female baby boomers' dietary habits and their attitudes together with their needs for future perspectives of dietary life. Our aim is to use these findings as a basic data when forecasting for food-related industries or policy making. A survey is being carried out for a total of 358 female baby boomers and analyzed by SPSS 12.0. The following is a summary of this study. The average age is 52.6 years old, most of them graduated from highschool (63.1%) and had a nuclear type of family (76.1%). Only 39.0% is composed of housewives, others had either full-time or part-time jobs. Self-assessment of stress is not so high and only 8.1% are dissatisfied with their lives. 38.2% are either overweight or obese in terms of BMI, and most of them are non-smokers (97.2%) or non-drinkers (63.0%). Their mean dietary habit scores are $70.6{\pm}11.8$, and the scores show significant relations with their education levels (p<0.01), monthly income (p<0.01), life satisfaction rates (p<0.001), stress levels (p<0.001), smoking habits (p<0.05), drinking habits (p<0.05), regular exercises (p<0.001) and regular health check-ups (p<0.05). The rate of skipping breakfast, lunch and dinner are 18.2%, 1.1%, 5.2% respectively. The main reason for skipping breakfast is the 'lack of time'. With regards to the frequency of grocery shopping, almost half of the subjects (55.7%) said '1~2 times per week' and bought mainly raw food sources such as vegetables, fruits, and meats. The majority of the subjects (91.3%) report that they cooked meals at homes, and took about 1 hour of time. The subjects also point out that cooking was a bothering task, and only 46.4% would prepare meals at home, while others would rather eat out or eat convenience foods. The main reasons for not wanting meal services in the elderly welfare facility are because they didn't want to live such places (48.4%) and the meals are tasteless (31.3%). As for delivery meal services, 60.1% are aware of it, and 39.9% would consider using it in the future. Factors to be considered when using the delivery meal service are sanitation (43.7%), nutrition (28.7%), taste (18.4%), price (6.3%), and brand name (2.9%). This study is expected to be used as useful information when developing food-related strategies for baby boomers in the future.

The purpose of this study is to verify the medial effect of social support in the process of the effect of working mother compatibility on spouse satisfaction. To that end, 727 employed workers who were kept samples until the 10th year (2017) were analyzed out of the data from the Korea Children's Panel Survey. Data analysis was performed for frequency analysis and regularity verification, and correlation and hierarchical regression were performed. In addition, the three-step method of Baron & Kenny (1986) was used to verify the mediated effect of social support. The results of the verification are as follows. First, the advantages of working mothers' work-in-home compatibility have had a static impact on their spouse satisfaction(ß=.164, t=4.078, p<.01). Second, the conflict between working mothers and their families has shown an amulet (-) impact on their spouse satisfaction(ß=-.134, t=-3.438, p<.05). Third, the partial selling effect of social support was verified in the process of the effect of the factors of conflict and advantages of working mothers on their spouse satisfaction. Based on the above research results, the compatibility of working mothers with working families suggested development and application of programs to enhance spouse satisfaction and social support.
