This study was designed to evaluate the Temporomandibular Disorders(TMD) with Tension-Type Headache(TTH) by age. Patients with TMD and/or TTH visited the Department of Oral Medicine, Kyung Hee University Dental Hospital were recruited to this study. Experimental group(n=170) is composed of TMD with TTH and control group(n=222) is composed of TMD without TTH. Evaluation list was pain quality, pain intensity, pain laterality, pain increase by routine physical activity and then it was analyzed statistically. The results were as follows ; 1. In the control group, pain quality was not significantly different by age. But, in the experimental group, pain quality was significantly different by age(p=0.042). 2. In the control group, pain intensity was significantly different by age(p=0.000). And, in the experimental group, pain intensity was significantly different by age(p=0.004). 3. In the control group, pain laterality was not significantly different by age. And, in the experimental group, pain laterality was not significantly different by age. 4. In the control group, pain increase by routine physical activity was not significantly different by age. And, in the experimental group, pain increase by routine physical activity was not significantly different by age. Therefore, it is considered that not temporomandibular disorder patients without tension-type headache but temporomandibular disorder patients with tension-type headache was influenced by age in the pain quality.

본 연구는 향에 대한 연령별 감성 구조를 밝히고, 향 감성에 따른 자율신경계 반응을 밝히려는 것이다. 실험 참여자는 연령별(10대, 20대, 40대)로 24명씩, 총 72명이고 자극향은 cederwood, grapegruit, teebaum, peppermint, rose 향을 사용하였다. 향이 제시되는 동안 혈류량, 피부온도, 피부전기반응, 심전도 반응을 측정하였고, 향에 대한 주관적 감성을 측정하였다. 향에 의한 심리적 감성 구조는 심미성, 강도, 자연성, 개성성, 낭만성의 다섯 요인이 확인되었고, 연령별로 차이가 나타나지 않았다. 향 선호도를 예측하는 감성요인은 연령별로 차이가 났다. 감성적으로 "나쁜"향은 "좋은"향보다 교감신경계 활동에 의한 자율신경계 반응이 더 크게 일어났다.

본 연구에서는 긍/부정 판단 과제 시 연령간 뇌파 반응의 차이를 밝히고자 한다. 실험 대상의 연령은 10명(20대 5명, 60대 5명)이었으며, 모두 오른손잡이였다. 실험과제는 의미과제와 일화과제로 구분되며 각각 12문항으로 구성된다. 의미기억과제 덧셈문제를, 일화기억 과제는 도형을 이용하였으며, 마우스 버튼을 눌러 긍/부정 판단 반응을 하도록 하였다. 뇌파는 PE1, PF2, F3, F4, O1, O2에서 단극유도법으로 측정되었으며, EOG를 측정하여 뇌파분석 시에 눈 깜박임으로 인하 noise를 제거하도록 하였다. 뇌파 분석은 원자료를 FFT(Fast Fourier Transformation)를 수행하여 각 대역의 상대적인 power를 구하는 방법으로 이루어졌다. 분석 결과, 반응 시간은 긍/부정판단간의 차이는 없었으나, 두 과제 모두에서 연령별로 유의미한 차이가 있었다. 긍/부정판단간의 따른 뇌파 반응은 명확한 차이가 나타나지 않았다. 연령에 따른 뇌파반응은 theta파, slow beta, fast beta에서 유의한 차이가 나타났다.

The purpose of this study was to compare the physical and psychological functioning by sex, weight and age in Judo athletes. The 124 participants; high school students, college students, and team players. They used physical tests to measure physical examinations by self-describing Knee injury and Osteoarthritis Outcome Score test, Foot and Ankle Outcome Score test, and Oswestry Disability Index, and psychological tests such as Profile of Mood Test, Athletes' Self-Management Questionnaire, and The Athletic Coping Skills Inventory-28, to examine the effects of physical and psychological functions of sports athletes. The physical tests of sex showed differences in knee and back, psychological tests of sex showed differences in mood state, self-management, and athletic coping skills. As a result of physical examination by weight, there was a difference in knee pain and sports items, psychological tests showed that there was a significant difference in mood state except for vitality. Physical examination by age showed differences in knee, ankle, and back. As a result of age-based psychological test, mood state test showed difference in all items except tension and vitality. There was a significant difference only in the items of physical management in self-management test. The results of this study are expected to be used as a basic data for sports injury training and medical technology development by sex, weight and age of Judo athletes.

The experiment was conducted to find out the nutritive value and microbial status of different wholesale cuts of goat carcass. The meat sample (4 cuts from each animal $\times$ 3 different age groups $\times$ 3 animals in each group = 36 samples) was obtained from 1-, 2-, and 3-year aged goats. The whole sale cuts were shoulder, rack, loin and leg of each goat carcass. To assess the quality of meat sample, the general appearance, color, smell, juiciness, proximate composition, pH, total bacteria, coliform bacteria, and yeast were studied. The mean pH value of different cuts ranges from 5.65-5.69 didn't differ significantly, but due to age differences the pH values (5.59-5.74) differed significantly (p < 0.01). The values of juiciness in different ages ranged from 32.24-42.10% which differed significantly (p < 0.01). The marbling of the cuts of rack portion was more pronounced than that of other cuts. The ranges of crude protein (CP) content of goat carcass (20.78-27.71%) differed significantly (p < 0.01) and leg portion contained higher CP than other portion. Fat contents of different cuts ranged from 2.66-11.47% differed significantly (P < 0.01). The moisture content of the carcass differed significantly which ranged from 69.20-73.31%. The ash content of the cuts of 1-year aged groups (0.99 $\pm$ 0.13%) was higher than that of other age groups and differed significantly (P < 0.01). The calcium (Ca) content did not differ significantly. The phosphorus (P) content was higher in one year old goat (0.15 $\pm$ 0.03%) than that of the goats of other ages. The total viable count (TVC) content of microorganisms ranging from 5.05-5.15 log cfu/g at different ages did not differ significantly. The coliform count (CC) of different cuts differed significantly (P < 0.01) which ranged from 2.56-3.05 log cfu/g; it also differed significantly (P < 0.05) in different ages (2.79-2.84 log cfu/g) and was higher in 1 year old goat carcass. The yeast count differed significantly in different cuts (P < 0.01) and ages (P < 0.05). From the study it is concluded that the age and different wholesale cuts have direct influence on quality of goat carcass.

This study was conducted to identify the structure of the sensibility and autonomic nervous responses to odor by ages. 72 participants, 24 each in their teens, twenties, and thirties were given odor stimuli, cederwood, grapefruit, teebaum, peppermint, rose. During the presentation of stimuli, participant were measured blood flow, skin temperature, skin conductance, and ECG and subjective emotion to each odor were evaluated, Five factors, aesthetic, intensity, naturality, uniqueness, and romantism were identified but there were no differences by ages. Emotional factors that predict the preference to certain odors turned out partly different by ages. However, odors that made participants feel sick created more autonomic nervous response than odors that made them feel good.

The respondents preferred rice cakes as wedding food to fishes, fruits, traditional sweets and skewered slices of seasoned meats. More than half of the respondents think current practices of wedding food is prodigal and has to be done in thrifty manner. As a ritual practices of wedding food were to be readjusted to the change of social custom depending on the degree of modernization. More than half (52.1%) of the housewives expected traditional wedding food should fade away. A conclusion was that it is necessary to develop modernized wedding food reflecting traditional wedding customs with economic costs.

부산지역 청소년 음성의 지속시간, 피치주파수 포만트 주파수 특성을 연령별, 성별로 분석하였다. 실제 발음 환경에서의 음성 패턴은 발성화자 개인 및 화자별로 다양하게 변화한다. 이를 모델 화하기 위해서는 다량의 음성 데이터로부터 통계적 방법에 의한 변화 요인별 파라미터 분석이 선행되어야 할 것이다. 실험에 사용된 데이터는 부산지역에 거주하는 청소년(초등학생, 중학생, 고등학생)들이 연령별로 3회 발성한 우화의 일부와 단모음(/아/,/이/,/우/,/에/,/오/)이다 실험 결과로부터 얻어진 지속시간, 주파수 특성 변화 패턴을 연령별, 성별로 구분하여 통계적으로 분석한 뒤 이를 정량화 하였다. 실험 결과로부터 부산 지역 청소년 음성의 지속시간, 주파수 특성은 예측된 바와 같이 기 연구된 성인 음성과 많은 차이를 보였으며 이는 부산 지역 방언의 DB 구축 시 설계자가 고려해야 할 기초자료로 활용 될 수 있을 것이다.
