  • This study was conducted to investigate the effects of computer attitudes such as anxiety, confidence, preference, usefulness, and computer literacy on their critical thinking ability, targeting college students at unspecified university universities. The period of data collection was from January 10, 2020 to January 17, 2020. A total of 213 people participated in the study. For data analysis, SPSS 18.0 was used for frequency analysis, Pearson correlation, x2 square, and simple regression analysis. As a result of the analysis, the difference of interests under the statistical significance level among general characteristics was Gender (x2=55.7***, p<0.001), Age (x2=407.5***, p<0.001), Resident (x2=127.5***, p<0.001) Family (x2=289.4***, p<0.001). In the simple regression analysis, computer liking (t=2.102, p<0.05) and computer use ability affected Truth seeking (t=-6.319, p<0.01), computer use ability was affecting analyticity (t=-5.630, p<0.01), computer use ability was affecting systematicity (t=-2.545, p<0.05), computer use ability was affecting maturity under statistical significance (t=-2.583, p<0.05). In conclusion, this study suggests that computer liking and computer use ability affect the sub-factor components of critical thinking disposition, truth seeking, analyticity, systematicity, and maturity, therefore the emphasis of this study is to emphasize that it is desirable to use the computer as a medium of learning based on computer literacy rather than worrying about excessive computer use.

  • The purpose of this study is to analyze the patterns of unconsciousness smartphone use by using an app and a self-administered survey on smartphone addiction comparatively and examine differences between recognition and behavior about actual smartphone use and examine how smartphone addiction influences learning. With an app installed in smartphones, this author collected and analyzed data about users' unconsciousness using patterns for a month. According to the results, there were significant differences found in users' recognition and actual time for use and also frequency of turning on the display. Also, 22% of the subjects used their smartphone over 8 hours a day, and 76% more than 5 hours. Over 95% turned on the display more than 100 times a day, and in extreme cases, they did more than 300 times. In the meantime, users not only in the smartphone addiction high risk group and the potential risk group but also in the general user group are found to use their smartphone too long and too much and frequently turn on the display. The apps that the general user group is mainly using are entertaining apps, and their school records are rather good, so excessive use does not always lead to addiction or learning disorder. Therefore, if we develop more diverse contents for learning and provide digital literacy education, smartphone use will bring more positive effects instead. In follow-up research, the app should be corrected to collect more accurate information, and as variables in personal areas, this researcher will also measure depression, anxiety, stress, self-esteem, and emotional control, and so on to see how they are associated with smartphone use.

  • Patient counseling is emerging as one of the most important roles of community pharmacists because the information on the standard labeling for the prescription drug is not sufficient to ensure the correct use of the drug. However, excessive workload of the community pharmacists in Korea discourages the provision of the effective patient counseling. The use of auxiliary label may be an efficient tool to help patients correctly use the prescription drug in this situation. As a preliminary study to encourage the use of auxiliary label, we have performed a survey analysis of familiarity and willingness of community pharmacists to use the auxiliary label. About three quarters of the participating community pharmacists have heard of the auxiliary label, however, there was not a single pharmacist who uses the label. Furthermore, only one fifth of the participating pharmacists were willing to use the label if they have to purchase. Therefore, it is recommended that governmental and non-profit organizations such as Korean Pharmaceutical Association educate community pharmacists regarding usefulness of the auxiliary label with focus on enhancing patient compliance and constrainment of healthcare expense.

  • This study identifies the effects of sodium sulfate and surfactants in the papain treatment of wool fabrics using L-cysteine and EDTA as activators. The research method involves the use of 2% L-cysteine and 7% EDTA as activators at optimal conditions, papain treatment of wool fabrics with the joint use of sodium sulfates and surfactants, and measurements of the weight loss rate, tensile strength, and whiteness. Results showed that for both 2% L-cysteine and 7% EDTA, the maximum papain activity appeared at 0.5% sodium sulfate concentration. In both cases, the papain activity was enhanced at sodium sulfate concentrations lower than 0.5%. In contrast, the papain activity declined at sodium sulfate concentrations higher than 0.5%. The joint use of EDTA with 0.5% sodium sulfate was proven to be very effective in improving the papain activity. The joint use of 2% L-cysteine with 0.5% sodium sulfate appeared slightly effective in improving the activity but resulted in excessive decrease in the tensile strength and whiteness, compared to improvement in the activity. The joint use of surfactants, in the case of L-cysteine, interrupted the papain activity and decreased the tensile strength regardless of the surfactant type and concentration. In the case of EDTA, however, the joint use with 0.1-5% non-ionic surfactants, 0.1-0.5% anionic surfactants, and 0.1% cationic surfactant appeared to improve the papain activity. The maximum papain activity was observed when 0.1% of surfactant was used, regardless of the surfactant type. The nonionic surfactant was the most effective in improving the papain activity.

  • Heritage resources have become important social assets as the global interests in heritage tourism increased. Utilization of heritage as unique tourist destination has positive effects on regional economy, which in turn plays an important role in heritage conservation. However, it was found that the essential quality of heritage resources has been degraded and even destroyed when excessive use was permitted. This undesirable side-effects of heritage tourism have led to the growing concern for sustainable tourism that can contribute to both utilization and conservation of heritage. In order for sustainable tourism to be effectively implemented, it is crucial for visitors to be aware of the need for heritage conservation because they are the most important consumers of the heritage. The purpose of this study was to suggest some basic information for sustainable tourism by investigating visitors' evaluation of conservation and use values of heritage resources. The study sites were the two Korean traditional temples(Sokrisan Bubjusa and Naejangsan Naejangsa) and contingent valuation method was used. 390 visitors in Bubjusa and 308 visitors in Naejangsa participated in the questionnaire survey. From the results, sustainable tourism is possible in such heritage areas as traditional temples because the participants had relatively balanced values for heritage conservation and use. The WTP for natural conservation value was found to be highest in both temples; visitors may be more agreeable with the heritage conservation plan if the sustainability of natural resource is emphasized. Also, the use value of heritage could be influenced by the tourism utilization of the area where the heritage was located. If there are no other famous tourist destinations except the heritage in the area, additional plans to develop alternative destinations should be prepared in order to formulate the agreement on the need to protect the heritage among visitors, local communities, and government.

  • 본 연구는 언론미디어에 자주 사용하고 있는 신어(신조어)에 대한 문제점을 일반인을 대상으로 인식조사를 분석하고 그 데이터를 기반으로 개선방안과 시사점을 도출하고 있다. 일반적으로 언론미디어를 통해 신조가 매우 많이 노출되고 무분별하게 활용되고 있음을 알 수 있고, 20~30대는 신어 사용에 긍정적이고 50~60대는 상대적으로 부정적으로 나타났다. 신조의 지나친 사용은 세대 간 갈등과 소외를 불러일으킬 수 있다는 점이 가장 큰 문제로 지적되고 있고, 한글 파괴, 부적절한 사회 인식 등을 제고할 수 있어 전반적으로는 올바른 우리말 사용에 대한 필요성을 인지하고 있다. 다만, 언론미디어는 소확행처럼 최신 트렌드에 맞는 용어 적재적소에 사용해 관심을 유발하고 콘테츠를 풍부하게 하려는 긍정적인 측면에서 신어를 사용하는 경우가 많았다. 이러한 문제점에 대한 대안으로 언론미디어 종사자의 자정 작용이 가장 중요하고, 미디어 리터러시 교육과 캠페인 등을 통해 올바른 우리말 사용을 권장하는 것이 좋다고 본다.

  • The objectives of this study are to investigate the prevalence of occupation related carpal tunnel syndrome(CTS) among workers in a condom industry : to analyse the sensitivity and specificity of clinical signs or symptoms such as hand diagram, Tinel's sign and Phalen's sign in carpal tunnel syndrome : and to test vibration threshold test using audiometry as a technically easy and noninvasive method in the diagnosis of carpal tunnel syndrome in stead of nerve conduction velocity (NCV). The study group was divided into exposed group(39 cases) and non-exposed group(48 cases) based on whether or not excessive use of wrist movements exsist. 1. There are stastically significant differences in symptoms and signs of carpal tunnel syndrome such as hand diagram, Tinel's sign and Phalen's sign between exposed and non-exposed group(p<0.05). 2. Six cases(9 hands) were comfirmed as carpal tunnel syndrome by NCV. Five cases(7 hands) belonged to exposed group, 1 case(2 hands) to nonexposed group. As there are significant differences in prevalence of carpal tunnel syndrome between two groups(p<0.05), excessive use of wrist in occupation is a risk factor of carpal tunnel syndrome. 3. When we use NCV as a gold standard in the diagnosis of carpal tunnel syndrome, sensitivity and specificity of hand diagram, Tinel's sign and Phalen's sign is as followed; hand diagram , sensitivity 88.9%, specificity 84.2% Tinel's sign ; sensitivity 55.6%, specificity 72.8% Phalen's sign ; sensitivity 14.3%, specificity 88.4%. Among above clinical signs and symptoms, hand diagram is the best clinical screening test. 4. The differences of vibration threshold between median and ulnar nerve at the same time are useful in the diagnosis of carpal tunnel syndrome but the time change of vibration threshold of median nerve over time are not sensitive enough. It is concluded that vibration threshold between median and ulnar nerve at the same time can be used as a supplementary or alternative criterion to indicate that the nerve dysfunction is located in the carpal tunnel.

  • With the new technology and the popularization of mobile phone. the functions and designs of mobile phone have been varied rapidly. However. based on the user's level of familiarity on mobile phone function and knowledge of information technology. the using behaviors of mobile phone. especially between the young users who are well acquainted with the latest function and technology and the over middle-aged users who are relatively not. would be quite different. A survey was conducted to investigate the various using behaviors of mobile phone in different age groups. The total number of six hundred and sixty-seven people from age seventeen to sixty participated in this study. The participants were divided into young group (age between 17 to 29) and the over middle-aged group (age between 40 to 60) to compare the difference group considered design. price. and function of the mobile phone as three important factors. on the other hand. the over middle-aged group considered quality of communication. price and ease of use as three important factors. All the respondents of the young group know how to use the text messaging function. however for the over middle-aged group. 40% of the respondents knows how to use the text messaging function. The over middle-aged group seemed mainly use the mobile phone for voice communication. however the young group had a tendency to communicate each other with short text message rather than through voice conversation. Twenty percentage of young group responded that they had an experience of pain or discomfort at the thumb. the thenar eminence area. or carpus area during pushing the mobile phone keypad. The excessive frequent use of keypad may cause the risk of repetitive strain injury (RSI). The results of this study could provide important information to understand the way of using mobile phone in different age groups. and also could be used to design and market the mobile phone.

  • As respiratory tract infections (RTI) account for about 60% of all antibiotic prescriptions in outpatient care setting, there are significant concerns about emerging resistance that are largely due to the excessive or inappropriate use of antibacterial agents for viral respiratory infections. This study was aimed to develop retrospective drug utilization review (DUR) program of antibiotics for RTIs using Delphi methods. Retrospective DUR criteria of antibiotics for RTIs were identified based on clinical practice guidelines and opinion of experts. Expert panel members were clinical doctors and pharmacists and Delphi method was applied by survey on 16 members of panels. The claim data from Korean Health Insurance Review & Assessment (HIRA) were used to examine trends in outpatient antibiotic prescription between Janunary to December of 2008. As results, Quality index for RTI was assessed for the claim type, antibiotics use of quantity, duration, number and cost. Antibiotic prescription rate for RTIs, Defined Daily Dose (DDD), and duration of antibiotics use were more recognized as significant quality index by experts' opinion. Use of first line agents suggested by guidelines was low and duration of antibiotics use was shorter compared to the recommendations. Antibiotics were over prescribed for RITs. However, dose and duration of antibiotics were under-used.
