INTRODUCTION The most commonly impacted tooth is the third molar. An impacted third molar can ultimately cause acute pain, infection, tumors, cysts, caries, periodontal disease, and loss of adjacent teeth. Local anesthesia is employed for removing the third molar. This study aimed to evaluate the efficacy and safety of 2% lidocaine with 1:80,000 or 1:200,000 epinephrine for surgical extraction of bilateral impacted mandibular third molars. METHODS Sixty-five healthy participants underwent surgical extraction of bilateral impacted mandibular third molars in two separate visits while under local anesthesia with 2% lidocaine with different epinephrine concentration (1:80,000 or 1:200,000) in a double-blind, randomized, crossover trial. Visual analogue scale pain scores obtained immediately after surgical extraction were primarily evaluated for the two groups receiving different epinephrine concentrations. Visual analogue scale pain scores obtained 2, 4, and 6 h after administering an anesthetic, onset and duration of analgesia, onset of pain, intraoperative bleeding, operator's and participant's overall satisfaction, drug dosage, and hemodynamic parameters were evaluated for the two groups. RESULTS There were no statistically significant differences between the two groups in any measurements except hemodynamic factors (P > .05). Changes in systolic blood pressure and heart rate following anesthetic administration were significantly greater in the group receiving 1:80,000 epinephrine than in that receiving 1:200,000 epinephrine ($P{\leq}01$). CONCLUSION The difference in epinephrine concentration between 1:80,000 and 1:200,000 in 2% lidocaine liquid does not affect the medical efficacy of the anesthetic. Furthermore, 2% lidocaine with 1:200,000 epinephrine has better safety with regard to hemodynamic parameters than 2% lidocaine with 1:80,000 epinephrine. Therefore, we suggest using 2% lidocaine with 1:200,000 epinephrine rather than 2% lidocaine with 1:80,000 epinephrine for surgical extraction of impacted mandibular third molars in hemodynamically unstable patients.

This study measures seriousness of adverse drug reactions (ADRs) among Korean physicians and pharmacists using two times surveys based on Delphi technique. Each participant scored 20 ADR terms on a scale of one to ten (10 being the most serious). We repeated the exercise for the 49 first survey respondents and 32 re-evaluated score. We compared the results of our survey with those of WHO CIOMS (Council for International Organization of Medical Sciences) working groups members conducted in 1995. The overall mean ADR seriousness score was 6.49 for Koreans and 5.12 for WHO CIOMS members, presenting Korean experts perceived more seriously for each ADR. Mean score changes for the same respondents showed similar trends regardless of access to the first survey results. There were no statistically significant score differences between the physicians and the pharmacists. The high consensus of seriousness for each ADR between the Korean experts and the WHO CIOMS members implies that the similar results are reproducible, suggesting the possibility of developing standardized tools for measuring the seriousness of individual ADRs in the future.

This study intends to analyze urban peoples' leisure choice attributes of rural areas from a rural demand perspective. For this purpose, this study investigates regional attributes considered in decision making processes for rural tourism destinations of urban residents using a conjoint model as a stated preference model. Based on literature reviews, two questionnaire surveys were conducted. The first questionnaire survey was performed in 4 cities including Seoul, Daejeon, Suwon and Chuncheon with 408 urban residents. The Second questionnaire survey was performed in 5 cities including Seoul, Chuncheon, Daejeon, Jeonju and Busan with about 1,060 urban residents. The study results suggest that the most important attribute in selecting rural ares for tourism are activity programs and convenience of facility, according to part-worth and vector model. The fitness level of model is 0.986, which is very significant. Among the 5 attribute's levels, the rural residents' kindness, the traditional and the ecological programs and the facilities about sign and lodging are more critical factors than other levels. Utilities of each levels decreases as cost and arrival time increases. Regarding the result of market segmentations, respondents having intention to visit can be divided into 4 group; (1) facility or program oriented type, (2) resident's kindness oriented type, (3) arrival time oriented type, and (4) negatively participant type. The results of leisure choice attributes can provide insightful information for regional planning strategies, such as selection of the type of market segments and the key factor of facility and space planning.

This study examined 12 types of towels with differing fabric material, function, quality, printing, pile length, twist, etc. from a towel company which manufactures and distributes products domestically. After 3 months of use by consumers, a consumer satisfaction survey was administered and results analyzed. Four types of towels were assigned to each group and the towels were used every day for 3 months. Participant feelings after using the towel for the first time and after using it for three months were investigated. The questionnaire consisted of 26 questions on a 5-point Licket-type scale. The first 13 questions measured perceptions of absorption, touch, fine fiber loss, contamination, deformation, drying speed, and design. Other questions compared differences between the two towel types in terms of their material, function, quality, printing, pile length, and degree of twisting. Results showed that, with regards to weight, consumers preferred towels between 130~150g and a thickness of around 1.7~1.8mm. The bamboo towel was considered superior to the cotton towel in terms of sense of touch and did not happen linter after washing. The antibacterial towel was considered better than the cotton towel in terms of absorption but in terms of contamination, participants felt the antibacterial towel became dirty more easily than the cotton towel. We thought that it might be influence of the color of towel. Low-quality towels became stiffer and misshapen more easily than higher-quality towels. But the study showed that the consumers did not perceive significant differences in the towels' quality. Printed towels became thinner and their color changed more with washing. The consumers preferred the design of jacquard towels to printed towels. Towels with short piles was happened more linter than the towel with long pile after washing. Non-twisted towel were better than the highly-twisted towel in terms of sense of touch and absorption but the non-twisted towel happened more linter after washing and became dirty more easily.

Purpose: This study compared the effects of three oral care methods on thirst and oral status in patients after general anesthesia surgery. Methods: Sixty five surgical patients were prospectively randomized into three groups. Each group received one of three oral care methods: wet water gauze, frozen water gauze, or frozen normal saline gauze. The outcomes of thirst and oral status were assessed three times by trained investigators blinded to the oral care methods. Assessment times were right after a participant's arrival to his/her room, and at 30 and 60 minutes after the pre-test. Results: The levels of thirst and oral status were significantly improved as time passed in all three oral care methods. While the level of thirst was not significantly different between the three groups, the level of oral status was significantly better with wet water gauze than frozen gauze groups, soaked in either water or normal saline. Conclusion: We recommend nurses choose one of three oral care methods based on patients' preferences since all three oral care methods showed similar effects in improving postoperative patients' levels of thirst and oral status.

Purpose: This study standardizes the position and direction of devices based on general user expectations and stereotypes. Population stereotypes are cognitive structures that contain the perceiver's knowledge, beliefs, and expectations about human groups. In this paper, the stereotypes that people typically expect when manipulating 'cylindrical key-in-knob locks' and 'lever-type water faucet handles' were investigated and data regarding their expectations were collected. Methods: Two sets of 600 participants, between 13 and over 60 years old, were recruited for the experiment. Each group was evenly subdivided into six age groups. Each participant was presented with cylindrical door locks mounted on a miniature door and actual lever-type water faucet handles mounted on a mockup sink. Results: If the cylindrical lock was positioned 'vertically,' 59.2% of the participants expected the device to be locked, and if the lever type faucet handle was positioned 'up,' 63.0% of the participants expected the device to be turned on. Thus, daily-use devices should be designed consistent with user expectations of operation. There was a significant difference between genders for manipulating the faucet handle between up and down. Conclusion: A more general stereotype may be defined by repetitive measurements under the same test conditions with fixed time intervals, as well as accounting for people with cognitive problems.

과학적 창의성은 새롭고 중요한 과학적 사실, 방법, 이론, 설명, 측정기구와 이를 낳는 활동이다. 지금까지 창의성에 관한 연구가 많이 이루어졌지만, 대학의 실험실에서 팀단위의 협동 연구에서 발현되는 과학적 창의성에 대한 이해는 부족하다. 본 논문은 우리나라에서 대표적으로 창의적인 실험실로 간주되는 서울대학교 RNA 유전체학 연구실에 대한 미시적, 경험적 참여관찰과 이론적 분석을 통해 실험실의 창의성을 구성하는 요소를 찾아내는 것을 목표로 한다. 창의적인 업적은 순간적인 영감에 의해서 이루어지는 것이 아니라 복잡하고 지속적인 진화의 과정을 필요로 하며, 이 과정에서 다양한 지식과 능력을 지닌 연구자들에게 맞는 분업과 협동 체계가 중요하게 요구된다. 또한 이러한 구조를 활성화 하는 실험실 문화와 실험실 책임자의 리더십이 중요하게 작용함을 관찰할 수 있었다.
