The purpose of this study was to evaluate self perception of occlusal status and recognition for orthodontic treatment as well as the prevalence of orthodontic treatment need objectively and subjectively. 3979 (male 2107, female 1872) school students of age 7~18 were analyzed by questionnaire and clinical examination and the results were as follows, 1. Perception of occlusal status on one's own was more generous than that of orthodontist's and it was affected by the factors such as age, patterns of malocclusion. 2. Recogniuon of subjective need for orthodontic treatment was more generous than that of objective need for the treatment, and factors such as age and sex of patient, parents' age and rate of education, income, occupation, classification of malocclusion and regional discrepancy were influenced. 3. Negative aspect of orthodontic treatment was influenced by the environmental factors. 4. A survey of want for orthodontic treatment showed one's alteration in recognition of the occlusal status with age and esthetic component was much more emphasized than functional component. 5. The multivariate discriminanat analysis for orthodontic treatment group showed that mother's rate of education, classification of malocclusion, demographic characteristics were critical in the determination of treatment group. 6. Test of inter-examiner reliability showed moderate coincidence.

In this study, the representative hand shapes for the adult Koreans were analyzed by factor analysis and cluster analyses. The analyses were conducted on the anthropometric data of 58 hand dimensions from 325 subjects having nonhomogeneous demographics. Maximum hand circumference, first phalanx length of index finger, and ratio between the two measures were the independent variables for the cluster analyses. The results of the study showed that Korean hand shapes can be divided into 2 clusters irrespective of their size for each of the male and female group. There were slight differences in component ratio of hand shapes with respect to the occupation and the age, but their differences were not statistically significant. The representative Korean hand shapes and their anthrpometric dimensions could be used to design and establish proper sizing system for various hand operating devices.

This study aimed to categorize consumers using super app functional characteristics to identify demographic differences, and analyze shopping orientations by consumer type. This data can be used by fashion and beauty companies for product planning and marketing strategies. To categorize super app consumers, data were analyzed with SPSS v.26.0 software using frequency, factor, reliability K-mean cluster, and distributed analyses, one-way-ANOVAs, and Scheffe verification. Cross-analysis was conducted to correlate super app consumer types with demographic characteristics. One-way-ANOVAs and Scheffe verification were used to analyze the differences in shopping preferences between super app consumer groups. As a result of our analyses, super app consumers were classified into four types: the ration type, the low-use type, the multifunction type, and the habit type. There were statistically significant differences between these types in age, occupation, marital status, average monthly household income, and shopping impact factors. Five super app user shopping orientations were identified: brand pursuit, pleasure pursuit, trend pursuit, risk perception, and economic orientation. The differences in the preferred orientation between super app consumer types were found to be statistically significant. The majority of respondents were multifunction type consumers. This group used the super app most frequently and effectively. They also demonstrated the highest scores for all five of the shopping orientations. The classification of consumer types in this study will allow the fashion and beauty industries to utilize super apps for more targeted product design and marketing.

Our study was designed to identify the difference in the mental health status among hospitalized patients due to occupational diseases and accidents and pre-employment physical examinees, and to identify the relationship between mental health status and socio-demographic variables, and to provide information useful to non-psychiatric clinicians in caring of such patients. Samples were comprised of 189 pneumoconiotic patients, 132 industrial accident-induced patients and 122 pre-employment physical examinees who were interviewed with 90-item symptom cheklist (SCL-90). The following results were obtained: 1) Mean scores of symptom dimension on socio-demographic subgroup showed higher tendencies in older aged, male, lower educated, miner, married, mining residence, and pneumoconiotic patients. 2) Mean scores of total samples on all symptom dimensions were as follows in the order of their magnitudes; Depression, Somatization, Obsessive-compulsive, Anxiety, Psychoticism, Interpersonal sensitivity, Phobic-anxiety, Hostility, and Paranoid ideation. 3) The highest mean scores on each socio-demographic subgroup were as follows; Depression in younger aged and Somatization in older aged; Depression in male Somatization in female; Somatization in lower educated and depression in higher educated; Somatization in miners and depression in non-miners; Somatization in married and Depression in unmarried; Depression in all kind of residences; Somatization in patients and Depression in pre-employment physical examinees(normal). 4) In consequence of stepwise multiple regression, the important socio-demographic variables were age, occupation, diagnostic classification, and residence. Age was the most imprtant variable in Somatization, Depression, Obsessive-compulsive, Anxiety, Phobic anxiety, Paranoid ideation, and Psychoticism. Occupation was the most important one in Interpersonal sensitivity and Hostility and also had significant realtionships with all symptom dimensions.

Objectives: The purpose of this study was to investigate the differences in smoking rates according to the major occupational categories in South Korea. Methods: The study subjects were a weighted sample of 24,495 men and 26,121 women aged 25-64 from the 2003 Social Statistics Survey, which was conducted by the Korea National Statistical Office. Occupation was classified according to the Korean Standard Occupation Classification. We computed the age-standardized smoking rates according to gender and occupations after adjusting for the education level, marital status, and self-rated health. Results: For men, the smoking rate in elementary occupations was two times higher than that of clerks (OR=1.98, 95% CI=1.74-2.26). In general, a more prestigious job(professionals) correlated with lower smoking rates, and less prestigious jobs correlated with higher smoking rates, except for legislators, senior officials and managers. For women, smoking among service workers was 4.1 times higher than among clerical workers (OR=4.11, 95% CI=2.87-5.88). For women, their occupations, except elementary workers, and the unemployed, the retired and the armed forces, failed to show significant differences in smoking compared with the clerical workers. After adjusting for education, occupational differences in the smoking rate for men were attenuated in most occupations, except for legislators, professionals, and technicians. Further adjustment for marital status and self-rated health had a minimal effect on the occupational differences in the smoking rate for men. For women workers with service or elementary occupations, the ORs of smoking were attenuated with adjustment of the educational levels. However, the ORs of smoking were increased in workers with service, sales or elementary occupations, as well as for legislators, and the unemployed, the retired and the armed forces, after additionally adjusting for marital status. Conclusions: More prestigious jobs generally correlated with lower smoking rates in both sexes. The anti-tobacco policy should consider smoking rate differentials by occupations.

주요 구인구직사이트의 직무분류체계가 사이트마다 상이하고 SW분야에서 제안한 'SQF(Sectoral Qualifications Framework)'의 직무분류체계와도 달라 SW산업에서 SW기업, SW구직자, 구인구직사이트가 모두 납득할 수 있는 새로운 직무분류체계가 필요하다. 본 연구의 목적은 주요 구인구직사이트의 구인정보와 'NCS(National Competaency Standars)'에 기반을 둔 SQF를 분석하여 시장 수요를 반영한 표준 직무분류체계를 구축하는 것이다. 이를 위해 주요 구인구직사이트의 직종 간 연관분석과 SQF와 직종 간 연관분석을 실시하여 직종 간 연관규칙을 도출하고자 한다. 이 연관규칙을 이용하여 주요 구인구직사이트의 직무분류체계를 맵핑하고 SQF와 직무 분류체계를 맵핑함으로써 데이터 기반의 지능형 직무분류체계를 제안하였다. 연구 결과 국내 주요 구인구직사이트인 '워크넷,' '잡코리아,' '사람인'에서 3만여 건의 구인정보를 open API를 이용하여 XML 형태로 수집하여 데이터베이스에 저장했다. 이 중 복수의 구인구직사이트에 동시 게시된 구인정보 900여 건을 필터링한 후 빈발 패턴 마이닝(frequent pattern mining)인 Apriori 알고리즘을 적용하여 800여 개의 연관규칙을 도출하였다. 800여 개의 연관규칙을 바탕으로 워크넷, 잡코리아, 사람인의 직무분류체계와 SQF의 직무분류체계를 맵핑하여 1~4차로 분류하되 분류의 단계가 유연한 표준 직무분류체계를 새롭게 구축했다. 본 연구는 일부 전문가의 직관이 아닌 직종 간 연관분석을 통해 데이터를 기반으로 직종 간 맵핑을 시도함으로써 시장 수요를 반영하는 새로운 직무분류체계를 제안했다는데 의의가 있다. 다만 본 연구는 데이터 수집 시점이 일시적이기 때문에 시간의 흐름에 따라 변화하는 시장의 수요를 충분히 반영하지 못하는 한계가 있다. 계절적 요인과 주요 공채 시기 등 시간에 따라 시장의 요구하는 변해갈 것이기에 더욱 정확한 매칭을 얻기 위해서는 지속적인 데이터 모니터링과 반복적인 실험이 필요하다. 본 연구 결과는 향후 SW산업 분야에서 SQF의 개선방향을 제시하는데 활용될 수 있고, SW산업 분야에서 성공을 경험삼아 타 산업으로 확장 이전될 수 있을 것으로 기대한다.
