This research seeks to clarify correlationship between satisfaction of visually impaired, hearing impaired and mentally disabled mothers and their burden of raising their children and whether communication between their children mediates their relationship. This research tries to set a standard performing method to alleviate burden of raising children and devise an effective parenting method. The study was done in cooperation with 13 welfare centers for the disabled in the Seoul area, 23 and performed 300 questionnaires were distributed. Hearing impaired person had answered by themselves, and visually impaired were provided with disability aid, by reading the questionnaire to them. 210 responses were collected, and 187 were used for final analysis. Analysis showed that burden of fostering showed a negative correlation between satisfaction as a mother and availability for communication. Moreover, communication with the children were shown to mediate the satisfaction as a parent and burden of raising the children. Thus, the goal is to reduce the burden of fostering for female disabled and increase their satisfaction as a parent as well as enhancing their communicational skills.

The objective of this study was to prevalidate the Organization for Economic Cooperation and Development's (OECD) rodent uterotrophic assay as a test method for screening of potential endocrine disrupting chemicals (EDCs). This study was conducted exactly as described in the OECD protocol documents. A positive control substance, 17$\alpha$-ethinyl estradiol (EE), was administered daily for three days to ovariectomized (OVX) Sprague-Dawley rats at various doses for determine the dose-response curve. Additionally, a pure antiestrogenic chemical, ZM189, 154 was administered to OVX rats at the same time EE to determine the effectiveness of the material against blocking the estrogenic effects of EE. At higher concentration of EE (10 $\mu\textrm{g}$/kg), a statistically significant difference in body weight gain and food consumption was observed compared to vehicle controls. In uterine responses, EE produced a dose-related increase in uterus weights compared to vehicle control. These increases were statistically significant at the >1.0 $\mu\textrm{g}$/kg doses. However, a similar dose-response relationship was not observed in vagina weight. A comparison of the two groups receiving ZM189,154 (0.1 and 1.0 mg/kg) with 0.3 $\mu\textrm{g}$/kg of EE and the group receiving only 0.3 $\mu\textrm{g}$/kg of EE showed dose-related decreases in uterus weights. However, statistical significance was shown in 1.0 mg/kg of ZM189,154. In conclusion, administration of EE produced a dose-related increase in uterine (wet and blotted) weights. Additionally, the 1.0mg/kg dose of ZM189,154 was effective in blocking the estrogenic activity of EE. These data suggest 3-day uterotrophic assay using OVX rats may serve as a good tool for EDCs screening.

This paper evaluates the influences of sex on the human emotions while coexisting with robots. When we consider human vision, robot's motion is the most important parameter which influences human emotions and must be well controlled for males and females emotions. On the other hand, when we consider human touch of sense, which is effective for cooperation transmitting mutual forces, the softness of robot is an important parameter for human emotions and must be also well controlled for males and females emotions. From these points of view, at first, we evaluate robot's motion under four different shapes of velocity pattern while handing over a cup to humans. Second, we evaluate robot's softness realized by impedance control. From the first experiment, we concluded that the conditions of choosing an adequate maximum velocity value and locating the velocity peak at the center or the first half of the duration are necessary for male's emotions. In addition, the smooth velocity decrease in the last part of the velocity pattern's duration is desired for female's emotions. From the second experiment, we concluded that females prefer lighter values of virtual impedance characteristics than males and any small increase on the heaviness of virtual impedance values is followed by the negative exponential change on human emotions.

Fouett$\acute{e}$ turns are repeated pirouettes which begin as a normal pirouette en dehors but include a movement that allows the rotational momentum lost to friction to be regained once each revolution. The purpose of this study was to investigate on orientation density of head/trunk to the front with and without music to which dancers perform the Fouette turn in time. 10 female dancers($21.0{\pm}1.4$ years old, height; $165.3{\pm}3.9$ cm, weight: $50.5{\pm}5.7$ kg) who are the students of S University participated in this study. It took shorter time to perform one revolution of fouette turn with music (930 ms) than without music (961 ms), which reason may be the shorter time of phase 2 in which the rotational momentum is not produced but lost to fiction. Orientation density of trunk to the front was smaller with music (.176) than without music (.196), while the one of head had not significant difference between with and without music. And the path length of marker on $2^{nd}$ left metatarsal bone during one revolution was smaller with music (35.7 cm) than without music (40.2 cm) but the difference was not statistically significant (p=.267).

General anesthesia is an effective behavior management method for disabled patients or uncooperative children who have difficulty in cooperation. The objective of this study was to assess and analyze dental treatment under general anesthesia in department of pediatric dentistry at Pusan National University Dental Hospital for 5 years. One hundred and nine cases of general anesthesia from June 2013 to May 2018 were surveyed for this study. Patients' distribution, reasons for general anesthesia, treatment pattern, agents for general anesthesia, duration of treatment, and visiting route were assessed. The proportion of male was higher than female and age group of 5 to 9 was highest. Reasons for general anesthesia were handicapped situations with or without systemic disease(52%), operative treatment needs(13.2%), uncooperative(15%) and others(29.8%). Most used agents for general anesthesia were thiopental sodium and sevoflurane. Dental treatment under general anesthesia for handicapped and uncooperative children has been increasing. Therefore, it is important to improve the system and efficiency of general anesthesia to provide satisfactory treatment.

The principal objective of this study was to evaluate the consumption patterns, the importance of product properties, and the satisfaction levels of blackberry and mulberry fruit beverage products(BMBPs) in the Jeonbuk area, Korea. Self-administered questionnaires were collected from 294 customers(male 40.8%, female 59.2%) residing at Jeonju in Jeonbuk area. Descriptive and comparative statistical analyses were completed using SPSS PC program(version 19.0). Approximately, 61.6% of participants consumed BMBPs 1-2times a year. Only 1.7% of participants consumed BMBPs everyday. The main information source about BMBPs was 'families/friends'. About 58.8% of participants responded that the main reason for purchasing BMBPs was 'for health'. The result indicated the overall importance level(3.94) was higher than the satisfaction level(3.41)(p < .001). The importance and satisfaction levels of the older group (50's) were significantly higher than the levels of younger group(20-30's)(p < .01 ; p < .05). According to the IPA(Importance-Performance Anslysis), 'price' and 'credibility' of companies were the most important properties that had to be changed as soon as possible to increase satisfaction with BMBPs. Therefore, to increase BMBPs'-consumption, quality improvements on these products through cooperation between BMBPscompanies, the regional government, and research institutions are necessary.

Nutritional status of minerals of beef and dairy cattle and buffalo in central Thailand were investigated by evaluating the mineral concentrations in feedstuff and blood plasma of animals. Three crossbred beef cow herds, a native cow herd, a buffalo female herd and 3 dairy cattle herds which consisted of the herds of lactating cows, dry cows and heifers were studied in both rainy and hot seasons. Low Na concentrations (<0.07% on a dry matter basis) in pasture samples from the fields for a cross bred beef cow were observed. Copper concentrations in all the pasture samples ranged from 3.7 to 13.5 mg/kg. Iron and Se concentration in pasture samples had a wide variety ranging from 185 to 1,345 and 0.033 to 1.127 mg/kg, respectively. The concentrations of K, Ca, Mg, P, Zn and Mn in total diets were higher than the requirements for beef and dairy cattle. Some animals with subnormal plasma Cu concentrations(< $0.65{\mu}g/ml$) existed in each herd. The animals which showed subnormal plasma Se concentrations(< $0.03{\mu}g/ml$) were observed in beef cow herds. The concentrations of Ca, Mg and Zn in plasma of animals were normal. Attention should be paid to the deficiencies in Na, Cu and Se of the animals in central Thailand.

Marbled flounder Pseudopleuronectes yokohamae is a commercially important flatfish in the coastal waters of the East Sea off Pohang, Korea. Maturity and spawning dynamics of P. yokohamae were investigated based on samples collected by gill net and long line in the coastal waters off Pohang from January 2013 to December 2014. We analyzed monthly changes in maturity stage, gonadosomatic index (GSI), egg diameter, fecundity, and total length at 50% group maturity. We found that the spawning period was December to February, wherein fecundity ranged from 55,760 eggs at 20.40 cm total length (TL) to 1,559,007 eggs at 46.6 cm TL. The relationship between TL and fecundity (F) was F = 0.0017 TL^3.5604 (R² = 0.6984), and F increased with increasing TL. We estimated the TL at 50% group maturity as 27.4 cm for female and 23.5 cm for male P. yokohamae, respectively. The results from this research will aid in the development of policies on season and minimum catch length for sustainable production of P. yokohamae. We propose that it is necessary to conduct long-term ecological monitoring for this species because biological properties such as spawning ecology and growth performance are being affected by climate change.

Oriental melon (Cucumis melo L. var. makuwa) is one of six subspecies of melon and is cultivated widely in East Asia, including China, Japan, and Korea. Although oriental melon is economically valuable in Asia and is genetically distinct from other subspecies, few reports of genome-scale research on oriental melon have been published. We generated 30.5 and 36.8 Gb of raw RNA sequence data from the female and male flowers, leaves, roots, and fruit of two oriental melon varieties, Korean landrace (KM) and Breeding line of NongWoo Bio Co. (NW), respectively. From the raw reads, 64,998 transcripts from KM and 100,234 transcripts from NW were de novo assembled. The assembled transcripts were used to identify molecular markers (e.g., single-nucleotide polymorphisms and simple sequence repeats), detect tissue-specific expressed genes, and construct a genetic linkage map. In total, 234 single-nucleotide polymorphisms and 25 simple sequence repeats were screened from 7,871 and 8,052 candidates, respectively, between the KM and NW varieties and used for construction of a genetic map with 94 F2 population specimens. The genetic linkage map consisted of 12 linkage groups, and 248 markers were assigned. These transcriptome and molecular marker data provide information useful for molecular breeding of oriental melon and further comparative studies of the Cucurbitaceae family.

The purpose of this study was to analyze middle school students' consumption lifestyle and develop a program for measuring Ecological Footprint (EF) for them. For this study, 200 male and female middle school students in large cities, medium & small cities were selected to analyze their consumption lifestyle. It was also that the existing programs for measuring EF were studied and basic rules of setting up new EF indicators were established based on the results of survey and literature study. 15 indexes was selected by dividing the life areas into food, housing, traffic, goods and services areas and than the delpi computer programming tools was used to develop program for measuring EF in this study. The program for measuring EF can be used as educational materials for consumers' environment education in the areas of social environment education and school environment education. The followings are suggestions coming out of this study. First, it is required to revise and complement program for measuring EF analyzing the problems that occur when applying it to middle school students actually. Second, some data that used during normalization of EF ate originally from the USA. So it is necessary to change the data to meet the Korean situation. Third, it is necessary to have design work that can invite interests of students with consumers' environmental education materials through cooperation between environmental education experts and computer programmers. Fourth, it is necessary to have practical research with consumers' environmental education adding educational contents into EF measurement program. Fifth, it is necessary to develop a method for distribution an expansion of the program for measuring EF to make it usable in different types of environmental education materials.
