This study was to investigate the speech sound production characteristics and evaluation aspects of preschool children through word test and connected speech test. For this, the authors conducted Assessment of Phonology and Articulation for Children(APAC) to 72 normal children(24 three-, four-, and five-year-olds each) and analyzed difference in percent of correct consonant(PCC) and intelligibility according to age and sex, correlation between PCC and intelligibility, and speech sound error patterns. PCC and intelligibility increased with age but there was no difference according to sex. The correlation was statistically significant in 5-year-old group. Speech sound error patterns were different in the two tests. This study showed that children's speech sound production varied according to language unit. Therefore, both types of tests should be done to grasp their speech sound production ability properly. This suggests that current standard to identify language impairment only by PCC of word level requires review and further studies.

현대사회에서 청소년기에 발생하는 영양문제 중 가장 빈번히 나타나는 청소년기 비만은 성인 비만으로 이행되기 쉬우며, 당뇨병, 지방간, 고혈압과 같은 각종 성인병의 발생과도 관련이 있다. 또한 체형에 대한 관심이 증가하고 있는 현대사회에서 편견의 대상이 됨으로 인한 심리적 장애를 발생시키기도 한다. 이에 따라 비만인의 체중조절을 위한 다양한 교육프로그램들이 실시되고 있는데, 현재까지의 실시되고 있는 프로그램들은 강의식교육이 주류를 이루고 있어 적극적인 교육효과를 이끌어 내는데 많은 한계점을 가지고 있었다. 이에 본 연구자들은 지역보건소를 중심으로 2박 3일간의 청소년 캠프 프로그램을 통하여 VTR감상, CAN-Pro를 이용한 섭취 식단의 평가 및 영양상담, 영양뷔페, 역할극, 다양한 영양지식 응용게임, 일상생활에서 활용가능 한 운동교육, 비만의 원인과 건강과의 관련성 및 식사요법 등에 대한 강의를 실시하였다. 캠프 참가자들은 부천시에 거주하는 중학생으로 사전에 신장과 체중에 대한 조사를 바탕으로 비만으로 판정된 총 42명(남 28명, 여 14명)으로 하였다. 캠프 시작전과 후에 설문조사를 통하여 영양지식, 영양태도, 자아만족도에 관한 조사를 실시하여 프로그램 직후의 효과를 판정하였고, 일상적인 영양소섭취상태를 평가하기 위해 24시간 회상법을 통하여 캠프참가 전날의 식이섭취 조사를 실시하였다. 대상자의 평균 연령은 13.9세로 남녀학생 간에 유의적인 차이가 없었으며, 신장은 남학생이 160.7cm, 여학생이 156.8cm였다. 체중, 체질량지수, 비만지수, 허리엉덩이둘레비 및 체지방 함량은 남학생이 각각 75.5kg, 29.1kg/$m^2$, 30.1, 0.89, 33.3%이었고, 여학생이 각각 67.8kg, 27.5kg/$m^2$, 25.3, 0.81, 34.6%였다. 영양소 섭취량에 대한 분석결과 열량의 경우 남학생이 2137.7㎉, 여학생이 2059.7㎉ 섭취수준을 보였으며, 총열량에 대한 당질, 단백질, 지질의 섭취 비율은 남학생 57:14:29, 여학생 60:13:26으로 남여학생 모두 총열량에 대한 지질의 섭취 비율이 높았다. 프로그램의 효과 평가를 위하여 남녀중학생을 모두 합하여 비교하였을 때 프로그램 실시 후 영양태도가 유의적으로 향상되었으며(p<0.001), 자아만족도 및 영양지식에 있어서는 유의적인 변화가 나타나지 않았다. 그러나, 성별로 분류하여 비교 시 남학생은 영양태도(p<0.01)와 영양지식(p<0.05)이 유의적으로 향상되었고, 여학생의 경우에는 영양태도(p <0.01)에서만 유의적인 향상을 나타내었다. 이상의 결과에서 2박 3일간의 청소년 캠프는 남녀 비만중학생에 있어 영양태도의 향상을 가지고 왔으며, 남학생의 경우에는 영양지식에도 유의적인 향상이 나타났다. 그러나 영양교육의 효과가 실제적인 영양소섭취 및 비만도의 변화에 영향을 미치는지를 알아보기 위해서는 지속적인 추적 관리를 통한 효과판정이 필요한 것으로 보여진다.

The purpose of this study was to investigate the dietary habits, behaviors, and food consumption frequency according to gender and obesity level among middle school students in the Jeonju area. Subjects for the questionnaire were 450 middle school students (male 255, female 195) and were classified as either obese students (n=150 or non-obese students (n=299) by the obesity assessment method. The results were analyzed with SAS program (Version 9.1), and were as follows. 1. Dietary behaviors were significantly different in the rate of 'Skipping breakfast (p<0.05)', 'Duration of meal time (min) (p<0.05)' and 'Unbalanced diet (p<0.01)' between males and females. Dietary habits and behaviors also differed significantly for the rate of ‘Taste preferences (p<0.05)’, and 'Unbalanced diet (p<0.01)' between obese students and non-obese students. 2. Food consumption frequency per week was as follows. First, males were significantly higher than females in 'Instant noodle (p<0.05)', 'Milk (p<0.01)', and 'Soda pop (p<0.01)'; on the other hand females were significantly higher than males in 'Chocolate, Candy (p<0.01)'. Second, non-obese students were significantly higher than obese students in 'Instant noodle (p<0.05)', 'Hamburger, Pizza (p<0.05)', and 'Chocolate, Candy (p<001)'. Especially, non-obese male students were higher in 'Instant noodle (p<0.05)' and 'Hamburger, Pizza (p<0.05)'; non-obese female students were higher in 'Chocolate, Candy (p<0.01)'. In conclusion, an action program is needed to encourage healthful dietary behaviors, increased physical activity, and forming good lifelong habits.

Purpose: To evaluate the anatomical localization of neurovascular bundle at the level of the korean knee joint using a magnetic resonance imaging study and minimize the risk of neurovascular injury from arthroscopy surgery. Materials and Methods: The transverse and central axes were described on axial MRI scans of 100 korean knee joints. The distance between the neurovascular bundle and central axis was measured. The differences in neurovascular bundle localization according to sex and side were analyzed. The results were evaluated with SPSS(ver. 10.1). The influence of sex was evaluated by t-test. The difference between right and left side was evaluated by paired t-test. Significance was considered as p<0.05. Results: Whereas neurovascular bundle localization was lateral to the central axis in 94 cases(94%), it was on central axis in 6 cases(6%). There was no statistically significant difference of sex and side(P>0.05). Conclusion: Preoperative evaluation of neurovascular bundle with MR axial scans may prevent neurovascular injury when performing arthroscopic posterior cruciate ligament reconstruction and interventions on the posterior horns of menisci.

This study was to investigate the eating attitutes, food habits, perceived stress of high school students. Three hundred and fifty four high school students in Seoul area were surveyed to obtain the information from Sep. 18 to 26 in 1997. The average height and weight of high school students were 173.7 cm, 62.9 kg for male students and 162.5 cm, 52.6 kg for female students. The 52.5% of high school students were normal weight and 41.5% of them were underweight. Female students(46.7%) showed higher proportion of underweight than male students(37.0%). The students(50.9%) ate breakfast irregularly and most students(92.5%) ate Korean food for breakfast. The dietary changes of high school students over past few years showed that the intake of vegetable, fruit and yogurt were increased. The food habit score showed no significant difference by gender, mother's employment and monthly spending money. The nutritional knowledge score of female students were higher than the score of male students. Most high school students(93.9%) were highly stressed in their living. The stress score(3.35) of female students were higher than those of male students(3.15). However, excercise, eating slowly and good appetite could lower their perceived stress.

This study was carried out to investigate the carcass grade and characteristics of pigs by carcass weight and backfat thickness. Data used in this experiment were collected and analyzed from a total of 656 pigs composed of 128 gilts and 528 barrows at commercial public slaughter house. The carcass grade of gilts was superior to that of barrow. The carcass weight by gender tended to be heavier in castrated pig than in gilt. Backfat was significantly (p<0.05) thicker in castrated pig than in gilt. Differences between castrated pig and gilt on meat colour, marbling standard, water holding capacity, and marketing age were not significantly found. However, the level of carcass grade was higher ratio in gilt group than in castration. The appearance of percentage of PSE (pale, soft, exudative) of gilt group was superior to that of castrated group. There were significant differences among carcass weight in the marbling score (p<0.05) and water holding capacity (p<0.05). There was significant difference among backfnt thickness in carcass weight (p<0.05), marbling score (p<0.05) and water holding capacity (p<0.05).

Purposes: This study aimed to investigate the differences in the prevalence of obesity according to sex and age and self-rated health in adults with metabolic syndrome according to sex, age, and the presence or absence of metabolic syndrome. Methods: The study subjects were 5,674 adults, who completed all three components of the KNHANES VI-2. The subjects were categorized, using life transition periods, into young adults, middle-aged adults, and older adults. Research methods were selected based on the research objectives of the KNHANES VI-2. IBM SPSS 23.0 was used for complex samples cross-tabulation and a complex samples general linear model analysis. Results: Obesity was prevalent in 77.2% of young male adults, 66.2% of middle-aged male, and 52.3% of older male adults with metabolic syndrome, whereas it was prevalent in 72.4% of young female adults, 73.9% of middle-aged female adults, and 64.6% of older female adults with metabolic syndrome. Men had higher self-rated health than women. As age increased, self-rated health status decreased. Those with metabolic syndrome had lower self-rated health status than those without metabolic syndrome. Conclusion: The prevalence of obesity was found to be high in those with metabolic syndrome. This study found that based on sex, men had the highest self-rated health status, and based on age, young adults had the highest self-rated health status, whereas those with metabolic syndrome had low self-rated health status.

Background: The natural history of bacillary tuberculosis was studied in India and results showed that at the end of the 5-year period, 49% of the patients were dead, 33% were cured and 18% remained sputum-positive. The aim of this survey is to observe the natural course of the patients with intractable tuberculosis disease who were incurable with all drug regimens of the national tuberculosis programme(NTP). Method: Of the patients who have been found as intractable cases in Kang-Weon Province by the supervisory medical officer during the period from January 1,1987 to December 31,1992, 179 were eligible for this study. Sputum examination was done for those who were survived until October in 1993 at the Kang-Weon provincial laboratory of KNTA. 49 out of 179 patients were transferred to the private sectors and retreated with the combination of prothionamide, cycloserine, ofloxacin, enviomycin, etc. They seemed to have been bacteriologically cured, and so they were excluded from the study. Finally 130 patients were analyzed by modified life table method to calculate the fatality rate and the survival rate during the period of 7 years. Results: 1) 80.8% of intractable cases were male and 19.2%, female. 2) More than 94% of intractable cases showed moderately or far advanced Tb findings on their X-rays at the time of registration at health centres. 3) The cumulative case-fatality rate was 19.74% at the end of 1-year period and has risen to 34.55% by the end of 4-year period(increasing by 4.9% a year on an average). The case-fatality rate has shown no appreciable rise since then until the end of 7-year period. 4) The case-survival rate was 80.26% at the end of 1-year period and has decreased to 65.45% by the end of 4-year period. And then there was no appreciable change in the survival rate until the end of 7-year observation. Conclusion: The case-survival rate of intractable cases was higher than that of untreated pulmonary tuberculosis patients and they may have risk of spreading multidrug resistant organisms. It is time we made an effort to improve case-management qualitatively.

The Jeju native pigs of 168 heads (116 barrows and 52 gilts) were examined to investigate the carcass characteristics related to gender, meat quality grades and yield grades. The averages of carcass characteristics for Jeju native pigs were 72.94 kg for carcass weight, 20.98 mm for backfat thickness, 38.14 for Hunter L*, 4.68 for a*, 6.04 for b*, 5.61 for pH, 3.61 for visual plate meat color, 3.36 for marbling scores, 1.83 for meat quality grades and 2.08 for yield grades, respectively. The carcass weight of gilts was significantly higher than that of barrows (p<0.05). There were no significant differences between barrows and gilts in carcass percent, backfat thickness, and meat color. The pH of barrows was significantly higher than that of gilts (p<0.05). The differences between gender groups were significantly noticed in carcass quality grades, and yield grades (p<0.05). The carcass weight, carcass percent, backfat thickness, and marbling scores for pigs with high grades(1 and 2 grades) were significantly higher than those for pigs with low grades (p<0.05). However, there was no significant difference among 4 carcass grades. The carcass weight, carcass percent, backfat thickness, pH, and meat color for carcass with high yield grades were significantly higher than those for carcass with low grades (p<0.05). The meat colors for Hunter L*, a* and b* were not significantly shown in carcass yield grades.

Predominant explanations of the persistence of sex segregation ill occupations link job choices to profoundly gendered responses to childbearing and other family demands, arguing that women are more likely to seek jobs which are in some sense compatible with motherhood, either because they are family friendly (flexible, low intensity work) or because they are easy to exit and re-enter. In this paper, I examine the effect of occupational sex segregation on job exits into the labor market among women, with a special attention to the role of childbearing and child rearing. I use data from detailed employment histories gathered from the National Longitudinal Survey of Youth (NLSY) in continuous time event history models. My results indicate that women in female dominated jobs are less likely to exit their jobs than women in other types of occupations. Further this relationship is not shaped by motherhood. While mothers or pregnant women are more likely to leave work, mothers in female-dominated occupations are slightly less likely to leave employment than mothers in other occupations. These results are not consistent with the ideas that women's choice of female-dominated occupations expresses a gendered identity and women strategically seek jobs which accommodate maternal roles. Taken together, my findings do not provide support to the idea that women choose female-dominated occupations because they are easier to integrate with motherhood (except for the pregnancy period).
