Because students are spending more time in their classroom for learning and study, indoor air quality problems in school classrooms are very important. when the classroom is built for the first time, namely newly built school, the selection of inside finishing material is directly connected with indoor air quality problems especially with HCHO and TVOC. But until now, there is no plenty of study about this. Moreover, there are some concerns about the desks and chairs which are used in classroom will affect the air quality. but almost no study is being made at all Therefore, this study focuses on the field survey and analysis of classroom indoor air quality in newly built schools in Changwon. In this study filed surveys and analysis are conducted as follows. 1) The effect of the material difference in general classroom. 2) The effect of the material and loading ratio difference in special classroom. 3) The effect of the desks and chairs in general classroom.

Purpose: This paper aims to report the effects of Oryeong-san on lower urinary tract infection. Methods: Four women were admitted to Dunsan Oriental Hospital with chief complaint that was not supposed to be a symptom of urinary tract infection. During the admission, urine test showed pyuria with white blood cell and their chief complain also accompanied. We prescribed Oryeong-san three times a day, and then took follow-up 4 days later. Results: After treatment, symptoms of lower urinary tract infection were decreased and the results of urine test improved also. Conclusions: These cases indicate that Oryeong-san is effective in treatment of the lower urinary tract infection.

Objectives: The purpose of this study is to report the effects of herbal medicine on infertility caused by premature ovarian failure. Methods: The patient in this case was 38-year-old female. The patient was diagnosed premature ovarian failure by serum hormone assay. The chief complain is amenorrhea and infertility. She was treated by traditional treatment, such as herbal medicine (Buickjihwang-hwan), acupuncture and moxibustion. Results: After the treatment, the patient recovered the menstrual cycle and became pregnancy and delivery. Conclusions: This case shows that traditional Korean treatment might be effective in infertility caused by premature ovarian failure.

Objectives: This study was to establish safety and efficacy of using herbal medicine during pregnancy and to investigate patient's satisfaction. Methods: We investigated general pregnancy outcome, birth history, newborn infant's physical condition and patient's satisfaction. Survey respondents were 54 gynecological outpatients who visited Daejeon University Dunsan Oriental hospital from January 1, 2011 through February 28, 2013. Results: A total of fifty one cases maintained pregnancy and 3 cases had miscarriages. Forty seven cases delivered normally, 4 cases gave birth prematurely. There was no congenital malformation due to using herbal medicine and most of newborn babies had on the average weight and height and were healthy condition. The average score of patient's satisfaction was 3.44 point (Excellent=5). Conclusions: This study presents safety and efficacy of using herbal medicine during pregnancy.

Objects: The purpose of this study was to examine the differences of college students' big-five personality factors, academic adaptation, and psychological well-being according to cluster types based on the grit. Methods: The participants of this study were 190 college students. All variables were evaluated by self-report of college students. The data were analyzed by one-way ANOVA and two-step clustering statistics using SPSS 21.0. Results: First, a cluster analysis on a sample of 190 college students revealed four clusters: the more highly grit group, higher tenacity group, higher consistency of interests, and the less grit group. Second, there were significant differences of 190 college students' big five personality factors, academic adaptation, and psychological well-being according to cluster types based on the grit. Conclusions: These findings can be used as an important contribution to further research and educational practices for promoting the grit in college students. Also it suggests the need for health education to increase the psychological well-being of college students.

In this study, formaldehyde and benzene were selected as the arbitrary chemicals in accidental leakage to environment, and their physicochemical and biological characteristics and toxicity were studied. Also, the fate of these chemicals in soil and groundwater was studied based on the results of previous studies. They can be released into the atmosphere as gas or vapor phase, which then can be photochemically degraded. Since they have relatively high water solubility, they are likely to have high mobility in water and soil. Volatilization of these chemicals from soil is affected by the soil moisture content. Biodegradation of formaldehyde and benzene is one of the important pathways as well. Therefore, it is necessary to study the environmental impacts of leakage accidents of flammable chemicals such as formaldehyde and benzene. Further research on the fate of flammable chemicals in the environment is needed to take appropriate response actions to leakage accidents of flammable chemicals, and this will contribute to the development of practical guidelines to cope with leakage accidents.

The growth of cheap, industrial, mass-production-so-called "fast fashion"-has led to dramatic increases in levels of consumption. Inexpensive products tend to foster unsustainable consumption behaviors, which negatively impact the environment and increase pressure to obtain goods at lower and lower prices; this, in turn, has the competitive effect of decreasing wages. This study focused on the concept of socially responsible consciousness in relation to fashion products. Environmental and labor issue concerns were employed as major variables. Empirical data were collected from males and females, between the ages of 10 and 50. Demographic differences were found in SR consciousness. For example, participants in their 10s, 40s, and 50s had higher levels of SR consciousness than those in their 20s and 30s. In addition, consumers' levels of environmental and labor issue concerns had varying effects on the criteria they used to select clothing. Product category type was also an influential factor. Moreover, the analysis showed that SR consciousness was less important in the apparel industry than in the food sector. The study also found an attitude-behavior link in relation to the concept of SR consciousness. The link was stronger for environmental concerns than for labor issue concerns. This study aimed to develop a better understanding of current customers' characteristics and levels of SR consciousness.

This paper analyzed the posthuman features of the open-world adventure game. These games represent the player character as Posthuman Subject through the restrictions of information and body. The player explores all of the spaces to perform the quests due to nonlinearity of open-world. The interactions are restricted conflicts and it reveals through gameplay. The experiences as Posthuman Subject allow the player to embody the Hybrid Subjectivity and think about coexistence of human and inhuman.

In this study, various electrochemical experiments were carried out to compare the corrosion characteristics of AA5052-O, AA5083-H321 and AA6061-T6 in seawater. The electrochemical impedance and potentiostatic polarization measurements showed that the corrosion resistance is decreased in the order of AA5052-O, AA5083-H321 and AA6061-T6, with AA5052-O being the highest resistant. This is closely associated with the property of passive film formed on three tested Al alloys. Based on the slope of Mott-Schottky plots of an n-type semiconductor, the density of oxygen vacancies in the passive film formed on the alloys was determined. This revealed that the defect density is increased in the order of AA5052-O, AA5083-H321 and AA6061-T6. Considering these facts, it is implied that the addition of Mg, Si, and Cu to the Al alloys can degrade the passivity, which is characterized by a passive film structure containing more defect sites, contributing to the decrease in corrosion resistance in seawater.
