This study was carried out to investigate the seasonal and regional occurrence of the major pests on the oyster mushroom houses. The survey were performed in oyster mushroom houses located at 16 places, randomly selected throughout South Korea from July to August and October to Novbember in 1997. The six specie flies were found including Sciaridae, Cecidomyiidae and Scatopsidae flies. The occurred pattern of the flies were dissimilar in relative abundance depending on the survey time and regions. Of these, Lycoriella sp. (Diptera : Sciaridae) that occurred year around at the regions surveyed was the most serious and abundant pest. In this study, Coboldia sp. (Diptera : Scatopsidae), Its larvae feed on the mycelium, which occurred amount usually from July to August was also confirmed as a mushroom pest. The paedogenetic Mycophila sp. (Diptera Cecidomyiidae), its larvae caused severe damage on the mushrooms, was found abundant on the oyster mushroom bed from October to Novbember. While, other pests like nematodes, Achorutes amatus, Philomycus spp. and Scaphidium amurense were also observed on oyster mushroom bed.

鄭元福,朴東洵,姜弼敦 東亞大學校 1986 東亞論叢 Vol.23 No.1

蠶作安定多收性 育成의 重要性에 비추어 有用한 形質의 遺傳關係를 初期에 推定하고 效率的인 選拔을 爲한 基礎資料를 얻고자 形質相互間의 特性을 고려한 2個品種을 二面交雜하여 F??의 主要 形質에 대한 優性程度 및 組合能力 등을 檢定한 結果는 다음과 같다. 1. Vr-Wr graph에서 雌單繭重과 雄單繭重은 超優性으로, 雌繭層重, 雄繭層重, 雌繭層比率 및 雄繭層比率은 各各 不完全優性으로 推定되었다. 2. 各 形質에 대한 分散成分의 推定에서 雌繭層重, 雄繭層重, 雌繭層比率 및 雄繭層比率은 遺傳子의 相加的 效果가 優性效果보다 더 컸고, 雌單繭重과 雄單繭重은 反對의 樣相이었다. 優性程度와 平均優性程度에서도 雌雄單繭重에서 超優性이고, 雌雄繭層重과 繭層比率은 各各 不完全優性이었다. 3. 一般組合能力과 特定組合能力을 檢定한 바, 6個形質 모두 一般組合能力(GCA)이 特定組合能力(SCA)보다 높게 評價되었다. 4. GCA 效果의 경우, 蠶114가 雌單繭重이 6個形質中에서 가장 높았고, 蠶108이 雄單繭重, 雌繭層重, 雄繭層重, 雌繭層比率 및 雄繭層比率에서 各各 높게 評價되었다. SCA 效果는 蠶107×蠶113은 雌繭層比率에서, 蠶107×蠶114는 雄繭層重과 雄繭層比率에서, 蠶108×複形蠶은 雌繭層重에서, 蠶108×中14는 雄單繭重에서, 蠶113×綠東亞는 雌單繭重에서, 蠶114×複形蠶은 雌單繭重, 雄單繭重 및 雄繭層重에서, 中14×綠東亞는 雌繭層重, 雌繭層比率 및 雄繭層比率에서 各各 높게 評價되어 주로 奬勵蠶品種인 蠶108, 蠶114가 關與하는 組合에서 SCA 效果가 큰 傾向이었다. Since the estimates of the genetic relations between characters gave us effective basic informations about the selection of good strains of the silkworm, this experiment was carried out to estimate the degree of dominance and the combining ability for the some main characters of the silkworm such as cocoon weight and cocoon layer ratio and weight, using the 21 combinations of F??'s by diallel corsses of seven strains of the silkworm. As the result of this experiments, some conclusions obtained were as follows. 1. The male and female cocoon weights are inferred over dominance and their cocoon layer weights and ratio partial dominance from Vr-Wr graph. 2. The additive effect of gene on the male and female cocoon layer weights and ratio is higher than the dominance effect, on the contrary, the latter on both the cocoon weights is higher than the former. Also, in the average degree of dominance, both the cocoon weights are over dominance and the male and female cocoon layer ratio and weights are partial dominance. 3. The effect of general combing ability(GCA) on the 6 characters analysed in this experiments is higher than that of specific combining ability(SCA). 4. In the effect of GCA, the male cocoon weight of Jam 114 is the highest of 6 characters, the male and female cocoon layer ratio and weights of Jam 108 and the male cocoon weight of Jam 108 are relatively high. The effect of SCA on the female cocoon layer ratio of Jam 107×Jam 113, the female cocoon layer weight of Jam 108×Bokhyeong Jam, the male cocoon weight of Jam 108×Jung 14, the female cocoon weight of Jam 113×Nog Dong-A, the male and female cocoon weights and male cocoon layer weight of Jam 114×Bokhyeong Jam, and the female cocoon layer weight and the male and female cocoon layer ratio fo Jung 14×Nog Dong-A is estimated high. Generally, the combinations including the recommended strains of the siklworm such as Jam 108 and Jam 114 tend to be high in the effect of SCA.

강필돈,문석기 청주대학교 산업과학연구소 1997 産業科學硏究 Vol.15 No.2

Youth participant groups from two different programs -a Family Camp(FC. nature oriented site) and a Grand Youth Celebration Program(GYC. urban oriented site)- were selected and tested before and after joining the program with questionnaire(including P.O.I. : Personal Orientation Inventory) to evaluate the effect of outdoor youth upbringing program onto promotion of participants' environmental & socio-psychological perceptibility and self-actualization. It was found that two each program promotes participants' perceptibility to almost same level. But in case of FC Program, most effects work on pre-participation stage, in contrast to GYC Program on actual participation stage. The effects of two programs promoting self-actualization were as follows. 1. among P.O.I. items, significant effect was found in 'Feeling Reactivity', 'Self-Regard' from FC Program, and 'Intention', 'Self-Actualization', 'Self-Regard' from GYC Program. 2. the GYC Program did more effect than the FC Program did on the items of 'Intention' and 'Self-Actualization'.

누에나방(Bombyx mori)성충의 생존시수에 따른 지방체 세포의 미세구조 변화

강필돈,류강선,손흥대 한국응용곤충학회 1999 한국응용곤충학회지 Vol.38 No.2

본 연구는 서로 다른 수명 패턴을 갖고 있는 누에성충 중 두가지 타입을 이용하여 수행되었다. 장명품종(성충 수명이 15일 이상; LLS), 단명 품종(성충 수명이 5일 미만;SLS). 누에성충의 노화 생리를 밝히기 위해 장단명 암수에 있어서의 지방체 미세구조를 비교해 보았다. 단명품종에 있어서는, 암컷에는 조면소포체 및 글리코겐 과립이 세포질내에서 다량 확인된 반면, 수컷에는 활면소포체만이 세포질내에서 발견되었다. 또한 단명품종에 있어서는, 성충 3일째 이후 미토콘드리아의 용적이 비대해지는 경향을 보였으며, 많은 지방구 퇴화가 관찰되었다. 단명품종에 반해 장명품종에서는, 성충 5일째의 암컷은 비교적 정상적인 미토콘드리아와 핵막이 관찰되었다. 성충 15일째에 이르러서야 대부분의 세포막이 사라졌고 미토콘드리아가 비정상적으로 비대해졌다. 장명품종 수컷(성충 10일째)의 세포질내에서 다량의 지방과립이 관찰되었으며, 이 개체는 성충 15일째에 세포내용물이 모두 고갈되어 사망하였다. 따라서, 금후 수명에 관한 조직 연구를 위해서는 조직의 변화상을 관찰하기 용이한 단명품종이 적절할 것으로 사료된다. This study was carried out with two types of silkworm, Bombyx mori, adults having different life span: long life span (adult living for more than fifteen days; LLS), and short life span (adult living less for than five days; SLS). The fine structures of fat body cells in the young and the senescent males and females were compared in an attempt to elucidate the aging physiology of the silkworm adult. In SLS, there were many rough endoplasmic reticula (RER) and glycogen granules in the female cytoplasm, whereas the smooth endoplasmic reticula (SER) were observed in the male cytoplasm. Also in SLS, the mitochondria were swollen and had many poor osmiophillic inclusions (fatty degeneration) at three days after emergence. In LLS, compared to SLS, comparatively normal mitochondria and nuclear membrane were observed in even five day old female. In fifteen day old LLS female, however most of cell membranes were disappeared and mitochondria were abnormally expanded. Many fat granules were observed in the cytoplasm of ten day old male (LLS) which died with full autophagic vacuole (AV) collapsed at fifteen days. Therefore, it is suggested that SLS type is recommended for the study of aging tissue, because it is easier to monitor the changes in tissue structure.
