This study aimed to evaluate the effects of shaking stress in the hemolymph of the Manila clam Ruditapes philippinarum by quantification of nitric oxide (NO) levels. The clams were divided into 3 groups as follows: clams placed in a plain container (control), clams injected with nitro-L-arginine methyl ester (NAME, an NO inhibitor), and clams in a container filled with nylon fiber at a density of $1kg/m^3$. Subsequently, each group was placed in sea water and shaken at 100 rpm for 6 h. The concentration of NO was quantified by using DAF assay and Griess assay. Both the assays showed that while shaking significantly increased the NO concentration, the NO inhibitor reduced the NO concentration in the hemolymph of the clams tested. In addition, the nylon fiber, which was used as a filler, effectively prevented the increase in NO concentration. This result suggests that measurement of NO concentration is a useful tool for evaluation of physiological stress in marine bivalves. In addition, it should be considered that a filler is necessary when dredge fishing or the suspended clam culture method is developed.

The purpose of this study is to develop an educational program for Korean traditional food culture, which is consisted of diverse activity factors and educational contents of the elementary students, and to transfer Korean traditional food culture to the next generation effectively. We have developed the program on the basis of FIB(Fun Integrated Behavior) approach derived from the activity-based education theory. This program is consisted of 32 subjects related with Korean traditional food culture, which is planned to perform in special activity classes for 2 semesters. An instruction guidebook for teachers and a workbook for students have been also developed. The traditional food culture educational program which is developed in this study could be used as a practical educational tool in 'dietary life and culture class' or 'special activity class' which is recently being introduced as the nutrition education curriculum in the elementary school. Furthermore, we expect this program to be able to contribute to transferring Korean traditional food culture to the next generation and reinforcing the elementary schoolers' diet behavior through inspiring them with a realization of the superiority of Korean traditional food culture.

Emerging three-dimensional television (3DTV) as a new IT product shows a possibility that television is not for just watching broadcasting, but an attractive tool for applying it to our real life. Three dimensional television is generally more effective and attractive than two-dimensional television (2DTV). But it still needs continuous technological improvement to solve its inherent limitations until many customers decide to purchase 3DTVs without hesitation. Innovative products like 3DTV encounter a quality problem leading purchase decision by customers. Quality is regarded as one of the most important factors affecting customers to adopt and use the product. Furthermore, measuring quality effectively is considerable for the 3DTV research. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for evaluating 3DTVs in a view of quality. We describe quality criteria affecting the 3DTV selection through a literature survey and develope an analytical method for measuring quality. We classify the quality of 3DTV into four types and suggest a concept of the quality ratio as a measurement criteria instead of the quality gap. Though a numerical example, we show how priorities of 3DTV with versatile manufacturers is computed.

The BIM called information modeling is used by tool not only it will simply be appearing the image and can save the information. Recently, there is a lot of case that improves the construction productivity by using the BIM during the life cycle of bridge from order to management. Although we already recognize the advantage of BIM, it is a careful phase to use the BIM. Therefore, We made the BIM for bridge, evaluated the possibility that can build the object used in the civil engineer, studied about the utility, the improvement in order to use the BIM properly. As a result, the BIM can recycle the information by using parametric model and attribute the efficiency and accuracy on drawing and calculating the quantity. The BIM is able to help productivity increase by using the builded model after we spend the effort building a model in early stage.

The purpose of this research was to examine the effect of dance sports for twelve weeks on physical self-efficacy in post-menopausal depression obese women. A total 38 women participated in this study, and they were divided into three groups: mild-depression group(n=9), light-depression group(n=14) and control group(n=15). For the exercise program in this study, a dance sports program performed at an intensity of heart rate reserve 50~80%, 60 minutes of exercise time, and the frequency of 3 times a week. Physical self-efficacy for mild-depression group after 12-week dance sports program was significantly increased compared to before the exercise. Although light-depression group and control group didn't show significant increase in physical self-efficacy, dance sports is expected to act positively on mental stability, such as depression and hope used as an effective tool to improve the quality of life. Furthermore, we expect a convergence is achieved between the sports science and medical research sectors.

Objectives : We investigated the effectiveness and safety of intranasal phototherapy for allergic rhinitis (AR). Methods : We searched 8 electronic databases (PubMed, Cochrane Library, CNKI, CiNii Articles, OASIS, NDSL, KISS, KMbase) to identify randomized controlled trials (RCTs) that reported the use of intranasal phototherapy for AR from their inception until May 30, 2020. Two investigators independently searched, collected, and screened the RCTs. We performed data extraction and evaluation for risk of bias using the Cochrane risk-of-bias tool. Results : This study included 12 RCTs; six studies compared intranasal and sham phototherapy, of which four studies reported a significant inter group difference and two studies reported a significant difference partially. No significant changes in symptoms were observed between the phototherapy and conventional therapy groups. The phototherapy and concurrent acupuncture treatment group showed a significantly higher effectiveness rate compared with the group that received only acupuncture. Both the phototherapy and laser acupuncture group showed significant improvement in the symptom severity scale scores. Six studies reported mild adverse effects, such as dryness and nasal pain in the intranasal phototherapy group; however, no severe adverse effects were reported. Conclusions : This study confirmed the safety and effectiveness of intranasal phototherapy for symptom relief and improved quality of life in patients with AR. However, further studies are needed on this topic in order to demonstrate it clearly.

As a preliminary step to develop the Daily stress Inventory(DSI) for assessing minor stressors frequently experienced in everyday lift. We examined the reliability and validity of the DSI. The Daily Stress Inventory(DSI), the Beck Depression Inventory(BDI), the State-Trait Anxiety Inventory(STAI), the Social Readjustment Rating Scale(SRRS) and the Minnesota Multiphasic Personality Inventory(MMPI) were administered to 111 college students. Compared with the weekly DSI Event, Impact and I/E ratio scores of the American college students, the weekly event and I/E ratio scores of the Korean college students were significantly higher but weekly Impact score was lower. The internal consistency reliability of the DSI as computed by Cronbach alpha was .98. The DSI I/E ratio scores were significantly correlated with the scores of State Anxiety$({\gamma}=.27)$ and Trait Anxiety${\gamma}=.24)$, but not with BDI scores. And the SSRS scores were not significantly correlated to the DSI Event or Impact and In ratio scores. Significant correlations were revealed between the DSI Impact scores and the Sc and Ma scales of the MMPI. And the correlation between the DSI I/E ratio scores and the L, D, Hy, Pd and Pa scales of the MMPI was also significant. But no significant correlation was found between the DSI Event scores and all the scales of the MMPI. This study suggests that the DSI can be a reliable and valid tool to assess the minor stress frequently experienced in everyday life future study should be directed to obtain normative data based on more varied and larger population. Especially gathering additional evidences for the validity of the DSI using other minor stressor scale will be required.
