본 실험에서는 다래나무 및 노각나무 수액을 천연 건강음료로 개발하기 위한 기초 자료를 얻고져 물리ㆍ화학적 성질과 유리당, 무기물 및 구성 아미노산 등을 분석하였다. 다래나무와 노각나무 수액의 pH, 비중, 당도, 수분, 회분 및 조단백질의 함량은 거의 비슷하였다. 유리당 함량은 fructose가 다래나무 수액에서 378.4㎎/100㎖, glucose는 노각나무 수액에서 125.4㎎/100㎖로 가장 높은 함량이었다. 무기물 조성은 망간과 알루미늄을 제외한 모든 무기물에서 노각나무 수액에 비해 다래나무 수액에서 함량이 높았으며 특히 칼슘은 다래나무 수액이 172.0㎎/ℓ, 노각나무 수액에서 13.7㎎/ℓ로 다래나무 수액이 노각나무 수액보다 약 13배나 높은 함량을 보였다. 다래나무 및 노각나무 수액은 분석된 총 17종의 구성 아미노산 중 다래나무 수액은 4종, 노각나무 수액에서는 6종이 검출되었는데, 다래나무 수액은 cystine, aspartic acid, serine 그리고 valine의 순으로 노각나무 수액에서는 cystine, glutamic acid, aspartic acid, serine, valine 및 phenylalanine 등의 순으로 함량이 높게 나타났다. Natural compounds such as free sugars, minerals and composition amino acids in Darae(Actinidia arguta) and Korean stewartia(Stewartia koreana) saps were analyzed to establish to the basic data of foods. Free sugars of the saps determined were fructose and glucose which were detected higher amounts as 378.4 and 125.4㎎/100㎖, respectively, but sucrose and maltose were not detected. Among 10 kinds of mineral detected in the saps, the content of calcium in Darae and aluminum in the Korean stewartia saps was the highest 172.0 and 56.1㎎/ℓ, respectively. The calcium content in Darae saps was 13 times higher than that of Korean stewartia saps. The Darae saps were composed of 4 kinds of amino acids such as cystine, aspartic acid, serine and valine, and then Korean stewartia saps 6 kinds of amino acids such as cystine, glutamic acid, aspartic acid, serine, valine and phenylalanine. It is concluded that saps of Darae and Korean stewartia contain a good variety of natural compounds such as free sugars, minerals and amino acids to serve as an excellent source of very natural and health promoting drinks.

崔洛煥,杜政玩 全北大學校 1997 論文集 Vol.43 No.-

It makes the rational decision making more critical that the complexity, importance of marketing decision and the radical change of marketing environment followed by technical innovation. Therefore, this study aim to review the Analytic Hierarchy Process which could help a marketing manager to come to a rational decision making, to study the analyzing procedure by the software of AHP for personal computer applied to the case of marketing decision which developed for this study. For the purpose, we premised the decision making as a consecutive three process; intelligence, design and choice. Analytic Hierarchy Process should be an useful tool for the third one. From the application of the case of marketing decision to AHP, it revealed that the analytical and systematic approach were essential. Expert Choice, which is a software of AHP for personal computer, compelled the decision maker to analyze the case in terms of at least three hierarchies; goal, objectives and alternatives. In short, AHP enable the decision maker to incorporate all the facts, and to compare of which through addition and subtraction so that he/she could lead to a reasonable decision or re-evaluate it for an advanced decision.

최원준,성낙정,강영중,한상환 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.3

목적: 작업관련 근골격계 질환의 선별검사에 사용되는 두 종류의 증상설문지(NIOSH 스타일 설문지,노르딕 스타일 설문지)의 결과를 신체검사 결과와 비교하여 타당도를 평가하고,활용방안에 대하여 검토하고자 수행되었다. 방법: 인천에 위치한 3개의 제조업 사업장 근로자 208명을 대상으로 NIOSH 스타일 설문지와 노르딕 스타일 설문지를 작성하도록 하고,신체검사를 시행하였다. 신체 검사 소견과 과거병력을 바탕으로 한 환례정의를 최적기준으로 하여 두 설문지의 민감도,특이도,양성예측도,음성예측도,일치도를 구하여 타당도를 조사하였다. 결과: NIOSH 스타일 설문지는 민감도 59.5%, 특이도 68.0%, 양성예측도 68.0%, 음성예측도는 59.5%로 조사되었다. 카파계수(Kappa coefficient)로 나타낸 일치도는 0.27(95% confidence interval 〔CI〕=0.14∼0.40)이었다. 노르딕 스타일 설문지는 민감도 73.9%, 특이도 68.0%,양성예측도 72.6%,음성예측도 69.5%로 조사되었다. 카파계수로 나타낸 일치도는 0.42(95% CI=O.30∼0.54)이었다. NIOSH 스타일 설문지와 노르딕 스타일 설문지의 일치도는 카파계수 0.43(95% CI= 0.31∼O.55)로 나타났다. 증상강도의 합계점수가 2점 이상인 경우를 기준으로 했을 때,노르딕 스타일 설문지의 민감도는 72.1%,특이도는 70.1%이었다. 결론: 두 설문지 모두 적절한 타당도를 가지고 있는 것으로 평가되었다. NIOSH 스타일 설문지는 증상의 빈도,지속기간,강도를 조사할 수 있고 이에 따라 다양한 양성기준을 설정할 수 있다. 노르딕 스타일 설문지는 민감도가 높은 편이고,증상의 강도를 설문항목에 포함시킬 경우 양성기준을 다양화하기 쉽다는 점과 문항이 간단하고 작성하기 쉽다는 점을 장점으로 들 수 있다. 조사 목적과 작업장의 특성에 따라 두 설문지를 적절하게 활용할 수 있을 것으로 기대된다. Objectives: The study aimed to compare the validity of two questionnaires (NIOSH- and Nordic-style) which are used for the screening and surveillance of neck and upper extremity work-related musculoskeletal disorders. To evaluate the validity, clinical examination was used as the reference. Methods: Two types of questionnaire were filled out by 208 workers from three different plants in Incheon, Korea. Workers underwent clinical examination by three occupational physicians. The presence of a symptom or sign in at least one body region was regarded as positive in both results of questionnaire and case definition using clinical examination. Validity was evaluated by sensitivity, specificity, positive predictive value, negative predictive value and agreement (Kappa coefficient). For the Nordic-style questionnaire, the sum of the symptom scores was used to yield the ROC curve. Results: The results of the NIOSH-style questionnaire were sensitivity 59.5%, specificity 68.0%, positive predictive value 68.0%, negative predictive value 59.5%, and Kappa coefficient 0.27(95% confidence interval [CI]=0.14∼0.40). The results of the Nordic-style questionnaire were sensitivity 73.9%, specificity 68.0%, positive predictive value 72.6%, negative predictive value 69.5%, and Kappa coefficient 0.42 (95% CI=0.30∼0.54). For the Nordic-style questionnaire, sensitivity was 72.1 % and specificity was 70.1 % based on the sum of the symptom scores≥2. Conclusions: Both questionnaires demonstrated appropriate validity for the screening and surveillance of work-related musculoskeletal disorders. The selection of questionnaire may depend on the purpose of investigation and characteristics of the work place.

정낙수,최규환 한국전문물리치료학회 2001 한국전문물리치료학회지 Vol.8 No.3

Falls are the most serious health problems in elderly population. They are a major cause of premature death, physical injury, immobility, psychosocial dysfunction, and nursing home placement. To reduce the alarming rate of falls and related excessive mortality and morbidity, efforts must be made to detect persons at risk of falling and to prevent or reduce the frequency of falls. To facilitate such approaches, it is essential to find the cause of falling (and under what conditions) of the elderly and the factors that are associated with risk of falling. This study was aimed at designing interventions that minimize risk of falling by ameliorating contributing factors while maintaining or improving patient's mobility.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

지역소구광고효과에 대한 소비자의 자기지역중심성향의 역할 : 소비자의 정보처리능력수준을 중심으로

최낙환,김종호,황윤용 朝鮮大學校 經營經濟硏究所 2003 經營經濟硏究 = Management and economics research Vol.26 No.2

본 연구는 최근 기업들이 광고촉진의 한 수단으로서 많이 활용하고 있는 특정 감정 소구의 한 형태로서 지역소구광고의 효과를 소비자의 자기지역중심성향(CLOCAL)과 정보처리능력수준의 관점에서 검토하였다. 이를 위하여 본 연구에서는 소비자의 자기 지역중심성향과 지역소구광고에 대한 광고태도, 상표인지, 상표태도 그리고 구매의도 간의 구조적 관계를 살펴보고, 이러한 관계가 소비자의 정보처리능력수준에 따라 어떻게 차이가 나는지를 탐색적으로 살펴보았다. 그 결과 소비자의 자기지역중심성향은 광고태도와 상표태도 그리고 구매의도에 정(+)의 영향력이 있는 것으로 나타났으며, 정보처리능력수준별 광고효과에서는 정보처리능력수준이 낮은 집단의 경우 지역정서 소구가 반영된 광고태도가 구매의도에 정(+)의 영향력이 있었으나, 정보처리능력수 준이 높은 집단에서는 부(-)의 영향력이 있음을 확인하였다. The purpose of this article is to examine the influence of consumer localism (CLOCAL) on the effect of local appeals advertisement. This study uses level of ability to information processing to explore the moderate effect on suggested model. The results can be summarized as follows. First, consumer localism has positive effect on attitude toward advertisement, attitude toward brand and purchase intention. Second, consumer's level of ability to information processing has moderate effect between attitude toward advertisement and purchase intention path. As a result, the consumer has a low level of ability to information processing is likely to have an positive effect between two paths. In contrast, when the level of ability to information processing is high, attitude toward advertisement negatively related to purchase intension. Finally, implications of these findings for marketing managers are presented along with suggestions for further research.

The Effects of Chinese Consumers’ Self-Construal and Advertising Type on Brand Attitude

Nak-Hwan Choi,Huan Liu,Zhonghua Li 한국유통과학회 2018 Asian Journal of Business Environment (AJBE) Vol.8 No.3

Purpose - This study focused on the attitude differences towards harmony-focused Ad and uniqueness-focused Ad, also those towards brand advertised in each of the two type Ads between self-construals. Research design, data, and methodology - Main survey was conducted online with the people in China, and collected 107 data through harmony Ad questionnaire and 109 data through uniqueness Ad questionnaire. Anova and t-test were used to verify hypotheses. Results - First, More positive attitude towards harmony-focused Ad and the brand in it there was at interdependent Chinese consumers than at independent Chinese consumers. Second, the independent Chinese consumers and the interdependent Chinese consumers did not form significant attitude difference towards uniqueness-focused Ad. However the independent Chinese consumers showed more positive attitude towards the brand in the uniqueness-focused Ad than the interdependent Chinese consumers. Conclusions - By highlighting the attributes of Chinese consumers' self-construal, to appeal to interdependent Chinese consumers, marketers should develop harmony-focused advertisement, and they should appeal to independent Chinese consumers by using uniqueness-focused advertisement. However the harmony might be pursued as the main content in the overall environment by Chinese people. Therefore it is necessary for the marketers to consider the harmony even when appealing them by emphasizing the uniqueness.
