Purpose - The purpose of this study is to develop a tool to measure the corporate social responsibility activities of tourism and hotel companies using ISO26000 and to verify its reliability and validity. Design/Methodology/Approach - This study is the development of a tool for evaluating social responsibility activities of tourism and hotel companies. For this, as the first stage filer research, 4 experts developed the questions based on ISO26000. And 12 experts (academia, industry) were surveyed by Delphi to evaluate suitability. Finally, the validity and reliability of the development tool were verified for a total of 55 incumbents and related persons. Research Results - For the development of a tool for measuring social responsibility activities of tourism and hotel companies, based on the standard draft of ISO26000, questions that fit 7 core areas were composed (60 questions). In addition, a Delphi survey was conducted on a panel of 12 experts, and a total of 45 questions were derived. Finally, as a result of an exploratory factor analysis of 55 field experts, 20 items consisting of 6 factors were finally confirmed as a measuring tool for social responsibility activities of tourism and hotel companies. Research implications or originality - It is significant for the first development of a social responsibility activity scale suitable for the situation of tourism and hotel companies by applying ISO26000. This will raise awareness of the importance of social responsibility activities in the tourism industry environment, and will help tourism companies to develop a positive awareness of social responsibility activities and to prepare effective implementation strategies.

Purpose: Many substances in saliva or oral health care products interact with each other. The aim of this study was to investigate interactions between hyaluronic acid (HA), lysozyme, peroxidase, and glucose oxidase (GO) in enzymatic activities at low pH levels. Methods: HA (0.5 mg/mL), hen egg-white lysozyme (HEWL, $30{\mu}g/mL$), bovine lactoperoxidase (bLPO, $25{\mu}g/mL$), and GO ($50{\mu}g/mL$) were used. The influences of HA, bLPO, and GO on HEWL activity were determined by measuring the turbidity of a Micrococcus lysodeikticus suspension. The influences of HA and HEWL on bLPO activity were determined by the NbsSCN assay, measuring the rate of oxidation of 5-thio-2-nitrobenzoic acid (Nbs) to 5,5'-dithiobis(2-nitrobenzoic acid) $(Nbs)_2$. The influences of HA and HEWL on GO activity were determined by measuring oxidized o-dianisidine production. All experiments were performed at pH 4, 5, and 6. Results: HA and GO did not affect the enzymatic activity of HEWL at pH 4, 5, and 6. bLPO enhanced the enzymatic activity of HEWL at pH 5 (p<0.05) and pH 6 (p<0.05) significantly. The enzymatic activity of bLPO was not affected by HA and HEWL at pH 4, 5, and 6. HA and HEWL did not affect the enzymatic activity of the GO at pH 4, 5, and 6. Conclusions: Peroxidase enhances lysozyme activity at low pH, otherwise there were no significant interactions in enzymatic activities between HA, lysozyme, peroxidase, and GO at low pH levels.

본 연구는 우라늄변환시설의 해체과정에서 발생되는 콘크리트 및 구성부품에 대한 알파분광과 감마분광에 대한 방사선계측방법의 타당성을 입증하고자 한다. 우라늄변환시설내의 구성부품 및 내부벽면은 천연우라늄 물질로 오염되어있다. 스테인레스 스틸 파이프와 벽면의 콘크리트의 일부에 대하여 시료를 채취하고 알파분석과 감마분석을 수행하였다. 천연우라늄 시료(AUC)의 측정에서 0.01 Bq/g 이상에서는 알파선 측정결과와 감마선 측정결과가 잘 일치하지만, 0.005 Bq/g의 낮은 농도에서는 감마선 측정결과가 상대적으로 높게 평가된다. 변환공정의 천연우라늄인 $^{238}U$은 $^{214}Pb$, $^{214}Bi$ 와 $^{234}Th$, $^{234m}Pa$을 비교 측정하여 그 농도를 구할 수 있다. 우라늄변환시설의 벽면은 대부분 우라늄으로 오염되어있다. 우라늄변환시설 해체과정에서 발생되는 배경방사능 준위의 폐기물을 감마분광법을 이용하여 계측하여 보수적인 평가 자료로 활용할 수 있다.

Objectives : The purpose of this study was to investigate the differences of chemical composition or biological activities between decoction and commercial herbal medicines of Samchulkunbi-tang (Shenzhujianpi-tang, SKT). Methods : The extracts of SKT from decoction (SKT1) and two different commercial extractive granules (SKT2 and SKT3) were prepared. The index components of SKTs were analyzed with HPLC. The antioxidant activities of SKTs were studied by measuring free radical scavenging activities on ABTS and DPPH. The anti-inflammatory effects were determined by measuring NO, $PGE_2$ and IL-6 in LPS-stimulated RAW 264.7 cells. Results : The contents of 7 components were 1.40-6.08 mg/g in SKT1, not detected-4.75 mg/g in SKT2, 0.03-1.46 mg/g in SKT3. The scavenging activities on ABTS and DPPH of herbal formulas were increased in dose-dependent manner (SKT1>SKT2>SKT3). SKT1 significantly inhibited $PGE_2$ and IL-6 production and SKT3 slightly inhibited $PGE_2$ production in LPS-stimulated RAW264.7 cells. SKT2 showed no inhibitory effects on production of inflammatory mediators such as $PGE_2$ and IL-6. Conclusions : These results demonstrate that the decoction of SKT has more strong anti-oxidant and anti-inflammatory effects than that of commercial herbal medicines consistent with the contents of index components.

The inhibitory activities of various analogues of adenosine (Group I, Group II, Group III, Group IV, Group V) were assayed by using recombinant human placental SAH hydrolase. The activity of the SAH hydrolase was determined by measuring the formation of AdoHcy from Ado and Hcy. AdoHcy was analyzed by HPLC using C18 reverse-phase column. The peak of AdoHcy was monitored at 258 nm. Among the tested compounds, fluoroneplanocin A (LJ-276) was the most potent inhibitor.

Chemopreventive activities of polysaccharides from soybeans fermented with either Phellinus igniarius or Agrocybe cylindracea were investigated by measuring the induction of quinone reductase (QR), glutathione S-transferase (GST) activities, and glutathione (GSH) levels in the cell culture along with inhibition of polyamine biosynthesis. The polysaccharides from soybeans fermented with P. igniarius strongly (p<0.005) induced QR activity at all concentrations tested. The extract not only induced GST activity in a dose-dependent manner in the concentration range of 0.1-1.0 mg, but significantly induced GSH revels in cultured Hepa 1c1c7 cells with a maximal 1.4-fold increase at 0.1 mg. The polysaccharides from soybeans fermented with A. cylindracea were effective in inhibiting polyamine metabolism. These results suggest that polysaccharides from soybeans fermented with P. igniarius or A. cylindracea have cancer chemopreventive activities in in vitro models and, therefore, could be considered as potential agents for cancer chemoprevention.

Purpose: This study was done to investigate correlations among Health Promoting Lifestyles, Health Risk Indicators, Activities of Daily Living, and Depression of the in-house stroke patients. Method: The subjects were 58 in-house stroke patients in a health center and two welfare centers. Data was collected using questionnaires and measuring health risk indicators such as blood pressure, total cholesterol, triglyceride, blood sugar, body fat rate. Data was analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation coefficients. Result: The health promoting lifestyle performance showed a significant negative correlation with health risk indicators and depression. There was a significant negative correlation between activities of daily living and depression. Conclusion: Health promoting lifestyle which focus on regular physical check-up, medication, diet management, exercise, smoking cessation, drinking abstinence, and stress management should be developed to improve health risk indicator and depression of the in-house stroke patients.

This paper purports to investigate the statistical basic principles through "TRIZ-used 6-sigma integrated activity design" and further, to raise "the importance of measuring technical innovative activities based on 6-sigma integrated design methodology by organization". This paper intends to investigate how the activities of the best conditions, which are necessary for the stage of 6-sigma design, are chosen in the TPM-based 6-sigma integration activities. And it will examine the options, when used together with other technique, in the probability statistical methodology. Through the combination of the situations which are chosen when activity techniques, which are mostly used for production and technology, and 6-sigma integration activities are used together, it intends to practically use as the basic data for company standards.
