This article examines the sexualization of place under conditions of the compressed modernization and reflexive cosmopolitanism. In particular, I adopt Michel de Certeau's spatial didactic model of strategy and tactic to investigate the dynamics at play in the gay labelling of a Coffee Bean & Tea Leaf (Coffee Bean) in South Korea, and explore the 'gaying' that takes place within preconceived heteronormative space. Using interview data, I additionally explore the negotiation tactics and coping mechanisms at work when gays compete with heterosexuals for non-gay place. The results illustrate how gays gay in heteronormative space and how heteronormative space harmoniously embodies gay men. The findings suggest that spatial location and tactic play important roles in stimulating compromise of sexual territory. Gay Bean benefits from being nestled between locations with histories of tolerance, while it also prospers from reflexive cosmopolitan ideals of diversity and acceptance of others. Gay identity and gaying is interpreted as foreign in Korea, which buttresses gay performativity in spaces welcoming of foreigners and so-called "deviance." However, how gaying functions within place relies not only on spatial histories of tolerance outside, but also on the tactics of identity negotiation within. The findings suggest that spatial and tactical conditions induce gay individuals to police other gay-identified individuals when gays gay in so-called heteronormative places.

This study was carried out from March 2013 to July 2014 with the aim of examining folk plants used in Jeollabuk-do Province. The analysis of 885 surveys collected from 59 residents of 11 cities and counties shows that a total of 154 taxa composed of 137 genera, 140 species, 2 subspecies and 12 varieties belonging to 66 families are currently used in the province. Regionally, Wanju had the greatest variety with 135 taxa, followed by Gochang with 128, Muju with 104, and Jinan with 103. In terms of their use, the plants were most frequently used as food and medicine, with 112 taxa of edible, 62 taxa of medicine, 4 taxa of ornamental, 3 taxa of dye, 3 taxa of oil, 1 taxa of aroma, 1 taxa of sap, 1 taxa of spice, and 9 taxa of miscellaneous use. Regarding plant parts, leaves were used most often, followed by fruits, stems and roots. The coincidence degree between the standard names of plants and their local names was the highest in Muju at 59.4%, followed by Wanju at 51.8%, Buan at 51.0%, Gochang at 50.4% and Jinan at 46.3%. The information on how to use folk plants was almost always orally transmitted.

This study was conducted to evaluate feed value of imported hays and examine current situation of species and hay grade. To evaluate the quality of the imported hay, 133 pieces including 9 species of roughage types were collected at the national hay importers, the TMR companies and livestock farms from 2016 to 2018. The quality grades of imported hay were 3~4 and most imported hay were considered to had low. The ADF, Ash, TDN and DDM in feed composition of alfalfa by quality grades presented significant differences(p<0.05). The quality grade on alfalfa was not similar to the actual quality grades calculated through feed composition. The feed composition of grasses by quality degrees presented significant differences in all contents except DM and CP (p<0.05). As the distributed grasses of the unmarked quality grade was low quality and accounted for 49%, it is urgent to present quality standards based on feed composition. As these results, the grades of imported hays were lower than the marked quality grades. Therefore, the imported roughage's(hay) price that considered to only quality grades on the marked imported roughages(hay) package can cause a loss to the livestock farms as economic damage. An institutional arrangement should be established to review the quality grades of imported hay.

본 연구는 제주지역 일부 초, 중학생들의 간접흡연 실태와 그로 인한 현재 흡연 여부 관계를 분석하여 초, 중학생들의 흡연 예방 교육 계획 및 수립에 기초 자료를 제공하고자 본 연구를 시도하였다. 자료 수집 기간은 2009년 6월 29일부터 7월 11일까지 제주특별자치도내 초등학교 5, 6학년 아동 464명과 중학생 475명을 대상으로 설문지를 이용하여 조사하였다. 연구 대상자들의 간접흡연 노출 관련성은 가정불화, 성적, 친구관계스트레스가 있는 대상자에게서 높게 조사되었고, 가족 및 주변인의 흡연유무에 따른 간접흡연 실태는 부모 및 친구의 흡연으로 간접흡연에 노출되었으며 통계적으로 유의한 차이를 보였다. 간접흡연의 주제공자는 아버지며, 주 간접흡연 피해 장소는 집으로 나타났다. 간접흡연 노출 유무를 종속변수로 한 로지스틱 회귀분석 결과는 흡연하는 아버지를 둔 대상자가 그렇지 않은 대상자에 비해 간접흡연 노출이 높았으며, 흡연하는 친구를 둔 대상자는 그렇지 않은 대상자에 비해 간접흡연 노출이 높게 나타났다. 현재흡연 여부를 종속변수로 한 로지스틱 회귀분석의 결과는 남학생이 여학생에 비해, 중학생이 초등학생에 비해 현재흡연율이 높았고, 엄한 가정 분위기 속에서 생활하고 있는 대상자와 흡연하는 친구를 둔 대상자는 그렇지 않은 대상자에 비해 현재흡연율이 높았으며, 간접흡연에 노출 되었던 대상자에게서 현재흡연율이 높게 나타났다. 이상의 결과를 종합하여 볼 때 초, 중학생의 간접흡연 실태는 심각한 사회문제이다. 또한 대상자들의 현재 흡연은 간접흡연 노출과 관련이 있는 것으로 볼 수 있었다. 이러한 간접흡연의 노출 및 그로 인한 흡연율을 줄이기 위해서는 가정 및 학교와 공공장소 등에서 간접흡연에 노출되지 않는 제도적 및 환경적인 조치들이 우선되어야 할 것이며, 학생들을 대상으로 간접흡연에 대한 간접흡연 예방 교육 및 대처방안 교육이 조기에 지속적으로 실시되어야 하겠다. 또한 유치원에서부터 고등학교에 이르기까지 모든 학생들에게 필수적으로 흡연예방 교육을 수강하게 하고, 교사들을 위한 연수교육 실시, 학교 흡연예방사업에 부모나 가족을 참여, 흡연예방 사업의 정기적인 평가 실시 등 국가적인 정책이 동반되어야 할 것이다.

This experiment was conducted to investigate the effects of dietary Ca levels and some feed additives such as isoflavone and casein phosphopeptide (CPP) on eggshell quality and hatching egg production in aged egg-type breeder hens. A total of three hundred and sixty, 56-week-old Hy-Line Brown breeder hens were divided into six groups and fed experimental diets of two levels of Ca (3.3% or 3.6%) either with addition of 0.2% isoflavone, 0.5% CPP or devoid of all for 5 weeks. There were no significant differences in laying performances and settable egg production among the groups. Significant increases (P<0.05) in eggshell strength were observed with increasing dietary Ca and addition of isoflavone, but not with addition of CPP. Fertility and hatchability were not influenced by dietary Ca and addition of isoflavone or CPP. The treatment had few significant effects on tibial proximal compositions and breaking strength. The concentrations of Ca, P, estrogen and calcitonin in serum were not affected by the dietary treatments. These results indicated that relatively high level of dietary Ca in combination with isoflavone had a beneficial effect on improving eggshell quality in aged egg-type breeder hens. But hatching egg production was not affected by dietary isoflavone or CPP.

A total of 244 cereal samples (oat, sorghum, adlay, and proso millet) were collected from fields to examine the contamination of Fusarium mycotoxins in cereals during harvest season in 2017 and 2018. The contamination levels of deoxynivalenol (DON), nivalenol (NIV), and zearalenone (ZEA) were analyzed individually by using the immunoaffinity column clean-up method with ultra performance liquid chromatography, and fumonisins (FUM) were analyzed by using the QuEChERS method with liquid chromatography-mass spectrometry. Highest level of NIV contamination (120.0-3277.0 mg/kg) was observed in oat samples among the analyzed cereals. In the adlay samples, DON contamination was the highest (maximum level 730.0 ㎍/kg). The proso millet samples had a high frequency of detection of NIV and ZEA (61.5% and 57.9%, respectively), but the levels were low (average detection level of NIV, 75.6 ㎍/kg, for ZEA, 21.5 ㎍/kg). Among the cereal samples, sorghum had the highest contamination frequency of DON, ZEA, and FUM, and the co-occurrence of Fusarium mycotoxin was 70.0%, which was higher than the average of 29.9%. In order to safely manage Fusarium mycotoxin levels in cereals, continuous research on the development of contamination prevention technologies together with monitoring of mycotoxin contamination is needed.

In order to investigate the variations on the ratio of mannose to galactose in the seeds of Phaseolus angularis, 17 local strains (Yangyang, Pyeongchang, Ganghwa, Pocheon, Geumsan, Seocheon, Jincheon, Danyang, Tongyeong, Sancheong, Gumneung, Wolseong, Wando, Gokseong, Okgu, Jangsu, Bukjeju), which are located from $33^{\circ}15'N$ to $38^{\circ}11'N$, were selected according to their latitudes and geographical distances. The seeds of these strains were collected and their contents of mannose and galactose were analyzed. Mannose contents in the seeds were variable, ranging from 17.071 mg/g at its highest (Jangsu) and 6.488 mg/g at its lowest (Geumsan). The contents of galactose also showed remarkable differences, ranging from 9.477 mg/g (Wolseong) to 19.877 mg/g (Jangsu). The local strains were classified into 3 variation types - coastal type I (Wando, Okgu, Bukjeju), the inland type (Jangsu, Weolseong, Danyang, Geumneung, Pyeongchang, Sancheong) and coastal type II (Ganghwa, Seocheon, Tongyeong, Jincheon), as well as 4 strange strains (Gokseong, Yangyang, Pocheon, Geumsan) according to the geographical climatic type and the ratio of mannose to galactose, which indicate the hardness of seeds in Leguminosae and ranged from 0.64 to 1.22. The variation types are very significant genecologically as evidence for microevolution related to natural and artificial selection in cultivated plants.

This study was conducted to evaluate the sanitary quality of sun dried sea foods being distributed in the markets located in Busan city. Twenty one kinds of sun dried sea foods, 9 kinds of fish and shellfish, 5 kinds of mollusca and 7 kinds of seaweed were examined during the Period from September to December in 1970. For the evaluation of sanitary contents of sanitary indicative bacteria such as coliform group, fecal coliform, fecal streptococci and enterococci, and plate counts were determined. The results obtained were as follows: 1. Through out all the samples examined, the numbers of fecal streptococci and enterocccci were much greater than those of coliform group and fecal coliform. 2. Generally, the contents of enterococci exceeded MPN of 1,000 per 100 grams through all samples examined, while fecal coliform MPN'S were less than 18. 3. The median value of coliform group MPN was 78 and those of fecal streptococci MPN was 3,300 per 100 grams, The median value of the plate counts was $9.9\times10^4$ per gram, 4. Bacterial densities of the foods which had many chances to come into contact with hands were much higher than those of other foods which had not. 5. The bacterial contamination rate of seaweed was much lower than those of fish and shellfish. 6. No correlation between the numbers of sanitary indicative bacteria and plate counts was observed.
