Background and Objectives: Differences in morphology of auricular keloids possibly contribute to distinct results of treatment. The aim of this study was to evaluate clinical characteristics of the auricular keloids according to the modified Chang-Park classification and to compare the results of treatment including recurrence rate between the subgroups. Subjects and Methods: Clinical data of 15 patients of auricular keloids were retrospectively reviewed. The keloids were classified according to modified Chang-Park classification. Clinical characteristics, the presence of recurrence, and the duration required for the recurrence were compared. Results: Eight out of 15 patients (53.3%) were single sessile type (type II), followed by 4 patients of pedunculated type, 1 patient of multiple sessile type, 1 patient of buried type, and 1 patient of mixed type, respectively. Recurrent keloids after previous surgeries were noted in 7 out of 15 patients and most of them (6 of 7, 85.7%) were sessile type. Three patients who underwent surgery at our department showed recurrence. Conclusions: The classification of auricular keloids according to morphologic patterns can assist surgeons in choosing the appropriate management.

It is very difficult to control the expansion of reed at a wetland ecological park due to their aggressive reproduction capability. Therefore, proper topography and wetland hydrology should be provided before the construction of a wetland ecological park. Appropriate measures should be taken at the initial stages to prevent reed expansion. Field experiments were conducted at the newly constructed wetland ecological park for 15 months to develop methods to control the reproduction and expansion of Phragmites communis. A complete shading method had the best effect on the prevention of reed reoccurrence among other methods. Complete removal of the rhizomes controlled the reed growth to a greater extent than cutting the aboveground shoots. Water-level manipulation was also better than a half-shading method for the prevention of reed reproduction. These results indicated that soil properties and edge effects can influence the reed growth. Cutting only the aboveground shoots facilitates the growth of reed. These results suggest that reed control should be implemented repeatedly and an alteration in the wetland topography and hydrology may be more effective in the long term. Combination of treatments such as water-level management with shading should be considered to control the growth of reed. Adoptive management for created or restored ecosystem might be considered for accomplishment of its original purpose.

Objectives : We aimed to explore the relationship among fatigue and perceived stress, depressive mood in the working population. We also examined associations with demographic and life style factors and investigated the effect of individual coping skills on these associations. Methods : Fatigue Severity Scale(FSS), Perceived Stress Scale(PSS), Brief Encounter Psychosocial Instrument - Korean version(BEPSI-K), Beck Depression Inventory(BDI), Stress Coping Skill Questionnaire were administered to 621 civil servants. All of above and other demographic factors are self-administered questionnaire survey and this study is cross sectional. Results : Mean FSS score was 3.04 which was lower than 3.22, the severity cut off score. FSS, PSS, BEPSI-K, BDI were all higher in female. Subjects with active coping skills showed relatively low fatigue, perceived stress, depressive mood than those with passive coping skills. Logistic regression analyses indicated that the PSS, BDI, BEPSI-K in working population increase the risk of fatigue and regular exercise lowers the risk. Conclusions : Adults who were afflicted by stress, experienced depressive mood or were physically inactive were at much higher risk of feeling fatigue. Since no other large data sets are available for fatigue, the results from this study could serve a very useful purpose, to furnish a basis for comparison with future research results based on more complete data.

Zolpidem is a relatively new, short-acting, rapid onset, and nonbenzodiazepine hypnotics. Zolpidem selectively binds to the central benzodiazepine 1 (BZI) receptor subtype. The present study was designed to compare the hypnotic effects of zolpidem (10 mg), triazolam (0.25 mg), and placebo in 22 schizophrenic inpatients. Zolpidem, triazolam, and placebo were administered orally in a randomized, double-blind design. Compared with placebo, zolpidem and triazolam significantly decreased sleep latency (p<0.05), increased total sleep time (p<0.05), and increased improvement of satisfaction of sleep (p<0.05). Zolpidem decreased the number of awakenings significantly in comparison with placebo (p<0.05), but triazolam did not. In addition, both drugs were well tolerated and did not produce severe side effects. These results suggest that zolpidem is effective for transient insomnia of schizophrenic inpatients and zolpidem is superior to triazolam in hypnotic effect.

The purpose of this study was to investigate the salt-related dietary behaviors according to the stage of change model in middle school students from the Gyeongsangbuk-do area. Data were collected from, a total of 253 male and 210 female middle school students through. Self-reporting questionnaire. By stage of salt-related dietary behaviors, the 'Pre-contemplation stage' was comprised of 57.3%, the 'Contemplation stage' of 12.2%, the 'Preparation stage' of 7.4% and the 'Action stage' of 23.2% of students. There were significant differences in the stage of change according to the experience with salt-related nutrition education (p<0.05), wherein differences according to gender and parent's education were not observed. In the salt-related dietary behaviors, there were significant differences according to gender (p<0.05), pocket money (p<0.01), and the stage of change (p<0.001). Males had higher salt-related dietary behavior scores than females, while students who had more pocket money also had higher scores, and the action group had lower scores than the other groups. Among the 10 items of salt-related dietary behaviors, only 4 showed above the average score (2.92/5.00), including behaviors of liking kimchi, completely consuming snacks and instant foods, and drinking the broth of soups. The salt-related dietary score of males was higher than females, while the action group's score was lower than the other stages.

This study aimed to compare the cooling effect of specific body parts to increase workers' thermal comfort. The parts to be cooled comprised the head and neck; the coolant was a phase change material. The participants were ten men in their 20s of average size according to the 8th Size Korea. The experiment was conducted under the following conditions: 28.0 ± 0.5℃, 60.0 ± 5.0% RH, and 0.2 ± 0.1m/s. The exercise consisted of participants moving for 15 min at a constant speed of 80 BPM; later, a subjective sensation was performed, and the clothing surface temperature was measured. In doing so, heat, wetness, and discomfort after exercise were confirmed to have increased without a coolant. Significant differences over time appeared only when no coolant was used, showing that thermal comfort decreased. Despite the addition of coolant, the clothing surface temperature gradually increased over time, but it decreased with coolant rather than without it. Therefore, additional coolant areas, a lower temperature, and simultaneous cooling convection were required to improve thermal comfort.

학력의 교육투자수익률과 학력내 불평등의 추이 분석

박소영,Park. So-Young 한국교육재정경제학회 2015 敎育財政 經濟硏究 Vol.24 No.1

교육이 가지고 있는 기능과 성격은 다양하나 특히 현대사회에서는 소득의 원천이 될 수 있는 자격과 기술을 제공하는 핵심적인 장으로 기능한다. 특히 우리 사회는 빠른 학교팽창과 경제발전을 거침으로써 교육을 통한 노동시장내 성과의 변화가 동태적으로 변화해왔을 것이다. 그러므로 본 연구는 교육과 경 제적 성과와의 관계를 살펴봄에 있어서 시간의 흐름을 고려하여 그 변화를 살 펴보는 것을 목적으로 한다. ｢고용형태별근로실태조사자료｣와 ｢경제활동인구 조사자료｣를 이용하여 교육과 노동시장내 경제적 성과의 변화 추이를 교육수 준의 분포 및 학력별 교육투자수익률 추이와 소득불평등 분해를 분석해보았 다. 그 결과 우리 사회에서 교육에 대한 투자가 지속적이고 빠르게 증가했으 며 학교팽창은 노동시장내 공급자의 학력을 상향평준화시켰다. 교육투자수익 률은 1990년대 중반까지 하락하다가 상승하고 있으며 대졸자 이상과 고졸자의 학력간 격차 역시 전반적인 수익률 추이와 비슷한 증감 추이를 보이고 있으며 고학력자에 대한 임금프리미엄이 존재하나 연령에 따라 차별적으로 적용되고 있다. 임금을 활용한 소득불평등 지수는 1990년대 중반 이후 지속적으로 증가 했다. 그리고 소득불평등을 학력을 기준으로 분해했을 때 학력간 불평등 보다 학력내 불평등이 총불평등을 견인하고 있음을 확인하였으며 1980년대 총불평 등은 고졸･청년층이 주요한 역할을 담당했으나 2000년대 이후 총불평등은 중 년층･대졸이상 및 고졸이 소득불평등을 견인하고 있는 것으로 나타났다. 시간의 흐름을 고려한 학교팽창 및 교육투자를 통한 노동시장내 경제적 보 상의 관계는 다음과 같이 정리할 수 있다. 우리 사회는 고등교육자에게 경제 적 보상을 보장했으며 학교팽창을 통해 추가적인 교육투자를 가능하게 함으로 써 학력 인플레이션을 야기했다. 그리고 학력 인플레이션은 고졸자에 대한 하 향평준화 및 고등교육에 대한 대중화를 견인함으로써 학력별 교육투자수익률 의 격차 및 학력내 동질성을 약화시켰다. 그리고 동일 학력에 대한 직종별 이 질적 임금 책정 및 시장 내 대졸자의 비중 증가가 소득불평등을 증가시킴으로 써 Bourguignon et al.(2005)의 주장처럼 학교팽창의 증가가 소득불평등을 야 기하는 ‘진보의 역설(paradox of progress)’를 확인할 수 있었다. The purpose of this article is to estimate the returns to education and inequality over time. I analysed the Mincerian earning model and Theil entropy Index using 1980-2012 the occupational wage survey data. The major findings of the paper are as follows. first, returns to education in Korea declined until the late 1990s, has increased since then. The rapid expansion of education has caused an upward leveling of worker. wage premium for high education has been applied differently depending on the age group. Second, when the decomposition of income inequality based on education, total inequality was more explained within education than between education. Based on the results, there has ensured the economic rewards of higher education educators led to inflation by allowing for additional investment through education school expansion. Education inflation was causing the wage differential by education and weakened homogeneity within education.

Function of salivary gland and saliva composition can be an indicator of individual's health status. Recently, saliva has been thought to have a high potential for usage in the biomedical field to diagnose, evaluate, and prevent systemic health due to the technological advances in analyzing and detecting small elements such as immunological and metabolic products, viruses, microorganisms, hormones in saliva. As a diagnostic specimen, saliva has some useful advantages compared to serum. Because of simple non-invasive method, saliva sampling is quite comfort for the patient, and it doesn't require specialists to collect samples. The possibility of infection during the collection process is also low. For this reason, proteins, genetic materials, and various biomarkers in saliva are actively being utilized on studying stress, microbiomics, genetics, and epigenetics. For the research on collecting big data related to systemic health, the needs on biobank has been focused. Regeneration of salivary gland based on tissue engineering has been also on advancement. However, there are still many issues to be solved, such as the standardization of sample collection, storage, and usage. This review focuses on the recent trends in the field of saliva research and highlight the future perspectives in biomedical and other applications.
