  • 본 연구는 어업에 종사하는 어업인을 대상으로 작업복 착용실태와 불편사항 및 문제점, 작업복에서 요구되는 기능 등을 알아보고 이를 통해 어업에 적합하고 작업 효율성을 높일 수 있는 기능적 작업복 개발에 필요한 요구사항을 파악하고자 하였다. 본 연구는 전남지역의 어업인 124명을 대상으로 하였다. 분석은 SPSS 26.0 프로그램을 활용하였다. 본 연구에 참여한 어업인은 50대가 가장 많았고 남성이 약 85%이며, 근무경력은 10년 이상 20년 미만이 많았다. 작업복은 상하 분리형을 좋아하며, 방수성을 가장 중요하게 생각하였다. 착용 작업복에 대한 만족도는 땀투과성을 제외한 모든 항목에서 보통으로 평가되었다. 선호하는 색상은 무채색이 가장 많고 상하 분리형 스타일과 지퍼 여밈을 좋아하였다. 연령에 따라 작업복 구입 시 고려사항에 유의미한 차이를 나타내 30대 이하와 40대는 활동성을, 50대는 내구성을, 60대는 방수성을 가장 중요하게 생각하였다. 연령에 따른 작업복 만족도는 활동성, 압박감, 탈착성, 맞음새, 두께감, 기능성, 보온성, 옷의 무게감 등에서 유의미한 차이를 나타냈다. 본 연구를 바탕으로 하여 실용적이고 기능적인 어업용 작업복 개발이 이루어져야 할 것으로 생각된다.

  • Exposure-dose reducing effect was measured by using bolus, a tissue-equivalent material as a shield to obtain useful diagnostic images while minimizing the radiation exposure of thyroid which is highly sensitive to radiation during panoramic radiography. The experiment was performed within the period of 1 June 2001 through 30 June 2011 by measuring entrance surface dose and deep dose at the thyroid-corresponding site of a head and neck phantom. As a result, the entrance surface dose in the thyroid for using no shield was 43.84 ${\mu}Gy$ on the average, and the thyroid shield of bolus 10 mm in thickness reduced the dose by 15.45 ${\mu}Gy$(35.24%) to 28.39 ${\mu}Gy$ on the average. The use of a 20 mm thyroid shield resulted in the dose of 25.38 ${\mu}Gy$ on the average, a 18.46 ${\mu}Gy$(42.10%) drop from 43.84 ${\mu}Gy$ for using no shield. On the site 20 mm below the surface, a thyroid shield 10 mm in thickness had no dose-reducing effect, while a 20 mm thyroid shield reduced the dose by 0.06 mSv(20%).

  • This study is performed to verify the relationship between Korean's anniversary days and meals. To do so, three steps are carried out. First, literature review and mini focus group interview are performed to list up important anniversary days in our culture. Second, anniversary orientation scale(22 items) is developed. Third, a survey(n=486) is implemented to identify the relationship among demographic variables such as sex, age, and perceived economic level, psychological ariables such as self-esteem, life satisfaction, depression, individuality-relatedness, interpersonal sensitivity, materialism as a value and perceived social support, and meal frequency. The results are as follows: Female is significantly higher than male in anniversary orientation. And younger people(20~39 years old) are significantly higher than older people(over 40ties) in anniversary orientation. The higher life satisfaction, perceived social support, relatedness, interpersonal sensitivity, and materialism are, the higher anniversary orientation is. Lastly, middle and high anniversary orientation groups showed more meal frequency at the anniversary day than low anniversary orientation group.

  • Helicobacter pylori(H. pylori) has been associated with the cause of peptic ulcer and gastric cancer. H. pylori infection occur mostly during childhood and increase by aging. In route of transmission, Oral cavity does important role. So we employed this study to elucidate route of transmission by detection of H. pylori in infant saliva. We investigated 20 infants aged below 10 years and 20 teens aged below 20 years as study group and 71 adults aged 20 and over years as control group. H. pylori DNA was isolated from 5(25%) infants aged below 10 years, 6(30%) teens and 17(23.9%) adults by nested polymerase chain reaction(n-PCR). There was no statistically significant difference(P>0.05). The obtained results suggest that H. pylori infection is relatively common in saliva of Korean infant and oral cavity may be reservoir of H. pylori.

  • In this paper, we apply limited area mask operation and active contour model to accurately detect tongue area outline in tongue diagnosis system. To accurately analyze the properties of the tongue, first, the tongue area to be detected. Therefore an effective segmentation method for detecting the edge of tongue is very important. It experimented with tongue image DB consists of 20~30 students 30 people. Experiments on real tongue image show the good performance of this method. Experimental results show that the proposed method extracts object boundaries more accurately than existing methods without mask operation.

  • As a part of integrated study for technical communication between consumer and manufacturer of functional clothing, functional clothing consumers were categorized based on their perception of the functional outdoor jacket and the differences in the source of information and use of hang-tag were examined according to the groups. Questionnaire survey was conducted on 472 males and females in their 20s to 60s, who have experience of purchasing functional outdoor jackets. Perception of functional outdoor jackets was classified into four factors ('functionality', 'price', 'experience/knowledge' and 'brand/design') and the respondents were categorized into three groups according to the factors: 'unconversant/brand & design pursuing group', 'conversant/function pursuing group' and 'high-priced products preferring group'. 'Unconversant/brand & design pursuing group' was composed of high rate of office workers and students in their 20s and 30s who use internet most frequently as source of information while 'conversant/function pursuing group' was composed of high rate of professionals in their 40s and 50s who make the most frequent use of information on hang-tag. 'High-priced products preferring group', which has high rate of the elderly in their 60s and housewives, obtain their information mainly from salespersons. 'Unconversant/brand & design pursuing group' was satisfied with functional information more than other two groups and 'conversant/function pursuing group' concerned for the hang-tag and required more explanation of terminology used in hang-tag. The results effectively explained the features of consumer groups and their different responses toward the information of functional outdoor jacket.

  • This experiment was carried out to determine the optimum fertilizer level of N-P-K for maximum yield of grasses at hill-land pasture. The pasture species tested were orchardgrass, tall fescue, alfalfa and ladino clover. The results are summarized as follows: 1. The difference in yield of treatment 1, 2, and 4, 5 was significant at the 5% level. In other word, alfalfa yields from 6-30-30 kg/10a and 6-40-30 kg/10a (N-P-K) application were significantly increased over the yields from 4-20-20 kg/10a and 4-30-20 kg/10a (N-P-K). In observing the yield from the treatment 5 where 10 kilograms of phosphate was additionally applied over the treatment 4, it was increased in yield but failed to show statistical significance. With these results, the most optimum rates of N-P-K for alfalfa production are 6-30-30 kg/10a. 2. Ladino clover showed the highest yield at treatment 6 with statistic significance at the 1 percent level over the other treatments. Therefore, NPK rates of 6-30-40 kg/10a would be the most optimal rates for maximum production of ladino clover. 3. Orchard grass yield showed significance at the 1 percent level among other treatments except treatment 3 and 4. The highest yield was also shown at treatment 6 where NPK rates applied 40-30-40 kg/10a. 4. Tall fescue yield showed high significance at the 1 percent except treatments between 2 and 3, 5 and 6. The highest yield was observed at treatment 6 where NPK was applied 40-30-40 kilograms per 10a. 5. Nitrogen content of dry matter was 0.91-1.05% in 20 kg of N and 1.05-1.26% in 30-40 kg of N per 10a. The absorption rate of nitrogen applied was 23-31% regardless of the nitrogen level. Potash content of dry matter was increased in accordance with increasing K rates. 6. The gross income was the highest on the N-P-K application of 4-20-30 kg/10a in alfalfa and ladion clover, 40-30-40 kg/10a in orchardgrass and 30-20-20 kg/10a in tall fescus.
