Purpose: This study aimed to investigate the effect of stress and oral parafunctional habits on temporomandibular joint disorders (TMD) in college students. Methods: An online survey comprising 354 questionnaires was conducted from May 23, 2020, to June 21, 2020. The collected data were analyzed using Student's t-test, one-way analysis of variance, correlation tests, and multiple regression analysis. Results: The stress symptom score was higher in females than in males. The symptoms of physical stress were significantly higher among students from the Department of Public Health, whereas those of psychological stress were higher among students from the Department of Physical Education. Both TMDs and oral parafunctional habits were higher among females, students of the Departments of Arts and Physical Education, and seniors. The higher the stress symptom level, the higher the scores for TMD and oral parafunctional habits. TMD and oral parafunctional habits were found to be most affected by physical stress. Conclusion: These findings indicate that a reduction in physical stress is required to decrease the prevalence of oral parafunctional habits and TMDs among college students. This can be achieved by the incorporation of physical activity programs, which may aid in reducing the symptoms of physical stress.

김정희(Kim, Jung_Hee) 한국만화애니메이션학회 2013 만화애니메이션연구 Vol.- No.32

본 연구는 특정 학습자를 대상으로 한 영어 디지털 교과서는 사용자를 고려한 디자인이 필요하다는 데서 출발하였으며 사용자는 영어 공교육의 시작 학년으로 구체적 사물의 제시에 의한 인지와 이해가 쉬운 초등학교 3학년 어린이를 대상으로 하였다. 이를 위하여 선호도가 높은 3종 교과서를 중심으로 ‘크레스의 시각디자인 문법틀[Gunther Kress, 2006]’에 의해 디자인 분석을 시행하였고 그 결과에 의해 수정된 디자인으로 초등학교에서 두 차례의 사례연구, FGI, 설문, 관찰 분석을 통해 사용자의 특성을 고려한 영어 디지털 교과서 디자인에 의한 교육 효과에 변화가 있는지 실험하였다. 분석 결과 사용자를 고려한 디자인 요소로 수정한 영어 디지털 교과서가 학생들에게 만족도가 높았으며, 어린이들이 흥미를 가지고 수업에 집중하는 것이 관찰 되었다. 한편 사례 연구 결과 사용자에 맞춘 디자인 요소로 영어 디지털 교과서를 기획하는 것이 교육의 선호도 및 효과에 영향을 주는 것이 확인되었다. 본 연구 결과는 향후 초등학교 3학년 어린이를 대상으로 한 영어 디지털 교과서 디자인 기획에 있어서 디지털 교과서만을 위한 체계적인 디자인 가이드와 사용자 연령의 선호도 및 특성을 고려한 디자인 제안이 될 수 있을 것이다. This research comes from the premise that a student-oriented English digital textbook’s design should be age appropriate. Our study is intended for third-year elementary students, since that age is the onset of English education within the Korean national curriculum. Our proposal focuses on this age’s need for concrete information. Three popular textbooks’ designs were analyzed using Cress’s “Grammar Flame of Visual Design [Cress 2006],” and the results reflected in our modified book design. Via two case studies, a focus group interview, questionnaire, and observation analysis, we learned that the design of an age-appropriate digital English textbook changes the effectiveness of the education. An age-appropriate modified digital English textbook improves student satisfaction and interest. Our research proposes a systematic textbook design guide for age-specific preferences and characteristics.

작업 수준의 행위 표현 언어를 이용한 사이버강의용 아바타 시스템

김정희,임순범,Kim, Jung-Hee,Lim, Soon-Bum 한국정보처리학회 2004 정보처리학회논문지B Vol.11 No.5

최근 웹이나 가상환경에서는 아바타의 활용이 증가하고 있으나, 아바타의 행위를 사용자가 직접 제어하는 수준의 서비스는 이루어지지 못하고 있다. 또한 기존에 제공되었던 언어들에는 제어에 필요한 복잡한 세부 정보들이 많이 포함되어 있어서 사용자가 작성하기에 까다로움이 많았으며, 작성한 언어를 다른 작업 도메인에 적용하고자 할 때에도 언어를 수정하거나 재 작성해야하는 번거로움이 있었다. 따라서 본 논문에서는 아바타의 행위를 간단히 정의하기 위해, 작업수준별 아바타의 행위를 작성 할 수 있는 “작업 수준의 행위 표현 언어”와 동작에 관련된 세부적인 데이터를 작성 할 수 있는 “동작 표현 언어”로 각각 정의하였다. 또한 시스템 내에 “인터프리터”를 두어 동작 표현 언어를 자동으로 생성 할 수 있도록 함으로써, 사용자가 행위 표현 언어만으로 아바타의 행위를 쉽게 제어 할 수 있는 시스템을 구성하였다. 이러한 내용을 사이버 강의에 적용해 보고, 정의한 작업 수준의 행위 표현 언어를 기존 언어들과 비교하여 아바타의 행위를 얼마나 간단히 표현할 수 있는지 검토하였다. In spite of recent increase in the use of avatar systems in Web and Virtual Reality, there has not been a service that allows users to control directly the avatar behaviors. In addition, the conventional behavior control languages required a lot of complicated information for controlling the behaviors, so that users had difficulty using them. To apply written languages to a different task domain, moreover, it was necessary to modify or rewrite the languages. In this paper, for the avatar behavior control more simply define, “Task-Level Behavior Description Language,” which allows description the avatar behaviors in each task domain and “Motion Representation Language,” which enables writing detailed data for motion control. The system, developed in this paper, “included an Interpreter,” which automatically creates the Motion Representation Language, allowing users to easily control the avatar behaviors simply with the Behavior Description Language. The system was also applied to cyber classes, and the Task-level Behavior Description Language was compared with conventional languages to see how it was more effective in behavior description.

The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y<age<80y) and to compare with elderly controls. Obesity indices such as Body Mass Index (BMI), Percent Ideal Body Weight (PIBW), Waist-Hip Ratio (WHR) and weight were significantly higher in the hypertensive elderly than controls (p<0.05). TAS was significantly higher (p=0.001) in the hypertensive elderly than controls, and was significantly positively correlated with weight, BMI, PIBW, systolic blood pressure, diastolic blood pressure (p<0.05). Uric acid tended to be higher in the hypertensive elderly than controls and significantly correlated with TAS and BMI, while plasma concentrations of $\alpha$-tocopherol, $\beta$-carotene and ascorbic acid did not show their significant correlations with TAS. These results showed that the hypertensive elderly are prone to be obese and to have increased TAS. Due to unknown factors affecting TAS values, measurement of plasma TAS as a sole indicator of total antioxidant capacity is limited to fully understanding changes in the body's free radical trapping power. However, the results from the current study may suggest that hypertension and/or obesity might increase oxidative stress, followed by increased the body's total antioxidant defense system.

목적: 본 연구는 암병동 간호사의 임종간호에 따른 스트레스와 인지정도 및 교육요구도를 파악하고자 수행되었다. 방법: 본 연구는 서울과 경기도에 소재한 4개 종합병원 암병동에 근무하는 간호사 151명이었으며, 자가보고식 설문지로 자료를 수집하였다. 스트레스 측정도구는 40문항, 인지정도와 교육요구도 측정도구는 각각 27문항으로 구성되었으며, 수집된 자료는 서술적 통계방법으로 분석하였다. 결과: 암병동 간호사의 임종간호에 따른 스트레스 정도는 5점 만점에 평균 3.96점으로 높았으며, 영역별 스트레스는 업무량 과중이 가장 높았고, 임종환자에게 시간할애의 어려움, 임종환자와의 인간적 갈등의 순이었다. 임종간호에 대한 인지정도는 5점 만점에 평균 2.64점이었으며, 인지정도가 가장 낮은 문항은 죽음에 대한 아동의 이해였으며, 법적 측면, 진실통고에 대한 윤리적 근거의 순이었다. 임종간호에 대한 교육요구도는 5점 만점에 평균 3.25점으로 높았으며, 스트레스와 소진관리, 임종 전 관리, 의사소통 방법, 임종준비에 대한 의사소통, 마약성 진통제 관리에 대한 교육요구도가 높았다. 간호사의 일반적 특성에 따른 임종간호에 대한 스트레스는 유의한 차이가 없었으며, 임상경력이 길수록, 호스피스 교육기간이 길수록, 임종간호 횟수가 많을수록 임종간호에 대한 인지정도가 높았고, 암병동 근무기간이 길수록 임종간호에 대한 교육요구도가 높음을 알 수 있었다. 결론: 본 연구의 결과에서 임종간호에 대한 스트레스가 높고, 인지정도는 낮으며, 교육요구도가 높았던 내용을 토대로 하여 교육 프로그램을 개발, 적용하는 것이 필요하다. Purpose: This study was performed to identify the level of stress perceived by nurses who attend dying patients in the cancer care unit; their understanding regarding end-of-life care and related training needs. Methods: A cross-sectional descriptive study was conducted with 151 nurses stationed at the cancer care units of four general hospitals located in Seoul and Gyeonggi province in Korea. Data were collected using self-reported questionnaires and the response rate was 96%. The data were analyzed using t-test, ANOVA and Pearson's correlation analysis. SPSS 12.0 was used for data analysis. Results: Nurses experienced a high level of stress in the end-of-life care settings. Their understanding of end-of-life care was above the mid-point of the scale while their training needs for end-of-life care was relatively high. The more experienced the nurses were, the more stressed they were, particularly due to excessive workload. Nurses who served longer in the cancer unit tended to show greater needs for end-of-life care training. Conclusion: This study found nurses perform end-of-life care with a high level of stress but with insufficient understanding, and thus, showed great needs for related training. Such findings can be useful to develop an end-of-life care training program for nurses.

Purpose : This study examined characteristics of, problems of and services provided to hospice recipients and their family members at a home hospice organization. Methods : The subjects were 113 people who were discharged from one free-standing home hospice organization between November, 1994 and lune, 1999. Since the opening of the organization in November of 1994, it has provided hospice services at patients' homes with no charge. Data were collected from those subjects' records. Results : The average age of the subjects was 57.1 years; those aged 60 and over were 54%. Spouse was the most frequent(50.9%) primary caregiver followed by daughter-in-law and daughter. All the subjects were diagnosed as having cancer. Of those 41 subjects who did not know their terminal stage in the beginning, 31 subjects came to know their states. Of the subjects, 72.7% were referred from their physicians. On the average, the service duration and the number of home visits were 6.8 weeks and 7.2 times, respectively. Pain was the most prevalent problem of the subjects(89.4%). Medication management was the most frequently provided service followed by psychological supports. The reasons for discharge were death(88.5%) and refusal(8%). Home was the most frequent place of death(60%). Conclusion Home hospice service providers should be trained particularly in working with elders and in managing cancer pain. People need to be referred at an appropriate time for achieving goals of hospice. Community recognition of hospice services needs to be promoted.

This study explored how the family resilience of participants in self-sufficiency programs relates to their willingness to be self-sufficient and analyzed the mediating effects of family support in the relationship. The subjects of the study were 283 people in their 20s to 70s who are participating in a local self-sufficiency center in Gangwon-do. Statistical analyses were conducted using IBM SPSS 18, with descriptive statistics, difference verification and regression, and mediating effects analyzed following Baron & Kenny(1986). The results of the analysis are as follows. First, we conducted difference verification between the sociodemographic characteristics of participants in the self-sufficiency program and major variables. There was a significant difference in the willingness to be self-sufficient in terms of the caregiving family and household income. Family resilience differed significantly depending on age group, marital status, health condition, household type, caregiving family, and homeownership, while family support differed significantly in age group, marital status, health condition, household type, caregiving family, and debt. Second, we conducted a hierarchical regression analysis to determine the factors influencing the will of self-sufficiency of those participating in the self-sufficiency program and found that the better the health condition, the presence of caregiving families, and the higher the level of family resilience and family support, the higher the level of will to be self-sufficient. Third, analyses of the mediating effect following Baron & Kenny(1986) have shown that family support has a full mediating effect on the relationship between family resilience and the will to be self-sufficient. Thus, we have verified that family resilience and family support are important factors as an alternative to improving the level of willingness for self-sufficiency program participants.

전분발효 효모에서의 외래 $\alpha$-Amylase 유전자의 세포분열시 안정성 증진

김정희,김근,최영길,Kim, Jung-Hee,Kim, Keun,Choi, Yong-Keel 한국미생물학회 1994 미생물학회지 Vol.32 No.4

To develop a yeast strain which stably secretes both $\alpha$-amylase and glucoamylase and therefore is able to convert starch directly to ethanol, a mouse salivary $\alpha$-amylase cDNA gene with a yeast alcohol dehydrogenase I promoter has been introduced into the cell of a Saccharomyces diactaticus hybrid strain secreting only glucoamylase. To secrete both enzymes more stably without loss of the $\alpha$-amylase gene during a cell-multiplication, an integrating plasmid vector containing $\alpha$-amylase gene was constructed and introduced into the yeast cell. The results showed that the linearized form of the integrating vector was superior in the transformation efficiency and the rate of the expression of the $\alpha$-amylase gene than the circular type of the vector. The yeast transformant having a linearized plasmid vector exhibited higher mitotic stability than the yeast transformant habouring episomat plasmid vector. The transformant containing the linearized vector producing both $\alpha$-amylase and glucoamylase exhibited 2-3 times more amylolytic activity than the original untransformed strain secreting only glucoamylase. ${\alpha}$-Amylase와 glucoamylase를 동시에 안정하게 분비하여 전분을 일단계로 직접 에탄올로 발효시킬수 있는 효모 균주를 개발하기 위하여 glucoamylase를 분비하는 Saccharomyces diastaticus hybrid 균주에 쥐의 침샘 유래의 ${\alpha}$-amylase cDNA 유전자를 plasmid vector를 이용하여 도입하였다. 이 균주로부터 효소생산에 필요한 유전자를 잃어버림이 없이 안정하게 분비할 수 있도록 하기 위하여 $\alpha$-amylase 유전자를 효모의 염색체에 삽입시키기 위한 integrating plasmid vector인 YIpMS$\Delta$R(LEU2)를 제작하였다. 이 vector의 효모형질전환에 있어 원형(circular)상태와 제한 효소 XbaI으로 처리된 직선화된(linearized) 상태의 두가지 형태를 비교한 결과 형질전환 효율에서나 형질전환체내의 $\alpha$-amylase 유전자 보유정도가 모두 직선화된 형태의 경우가 원형상태의 경우보다 높았다. Linearized vecotr를 가진 효모 형질전환체에서의 유전자 발현 안정도는 세포분열을 거듭할수록 episomal vecotr에 의한 효모 형질전환체에서의 발현 안정도보다 우수하게 나타났다. 또한 이 linearized vector를 가진 형질전환체는 $\alpha$-amylase와 glucoamylase를 동시에 분비하여 glucoamylase만 분비하는 원균주보다 2배 이상의 전분분해력을 보였다.

This study was conducted to develop a novel tomato sauce using natural seasoning. The data was analyzed using SPSS for Windows (version 14.0). Two factors of the tomato sauce were varied was tomato paste and sugar. Nine tomato sauces were produced with various compounding ratios of tomato paste and sugar. The color, viscosity and sensory evaluations of the nine tomato sauces were determined. Items examined in the sensory evaluation were color, sweetness, viscosity and overall quality. Sweetness($4.44{\pm}1.36$), viscosity($5.16{\pm}1.28$) and overall quality($4.68{\pm}1.11$) of the tomato paste 340g and sugar 100 g sample got highest scores. Therefore, this composition was used as tomato spaghetti sauce. Tomato spaghetti sauce using a natural tomato sauce and artificial tomato sauce was prepared and subjected to a sensory evaluation. Items included in the sensory evaluation were taste, flavor, harmony, overall quality. In this analysis, all sensory item scores of the tomato spaghetti sauce using natural seasoning were significantly higher than when artificial seasoning was used. Therefore, the potential of commercialization of tomato sauces using natural seasoning was confirmed.
