This study explored whether mothers’ employment status and their perceived social support influence the extent of child neglect. Study subjects were 414 mothers of kindergarteners and 1st-graders. Questionnaires using Likert type scale were distributed through preschool and elementary school classes. Collected data were analyzed by SPSS/WIN 10.0.; descriptive statistics, t-test, ANOVA and Scheffé were applied. Study results showed: First, the most prevalent type of child neglect among mothers proved to be emotional neglect followed by physical, educational and medical neglect in order. Second, mother’s employment status was found to have significant impacts over child neglect among mothers. Working mothers tended to show relatively high rate of child neglect incidence than mothers who stay at home. Third, social support from husbands proved to be the most important factor in regard to child neglect by mothers; with lower support from the spouse would bring a higher child neglect incidents in the physicalㆍemotionalㆍeducational aspects. Study findings suggest that enhancing the intra-familial support system is very important as well as to establish formal social support systems outside of home to prevent child neglect.

본 논문은 온-오프 모델을 이용하여 일반 셀을 알고리듬의 성능을 분석한다. 다중화되는 다른 트래픽의 양을 증가시키면 일반 셀을 알고리듬의 파라미터인 최대 셀율의 위반 확률은 증가하지만, 또 다른 파라미터인 지탱할 수 있는 셀율의 위반 확률은 일정하다. 또한, 약속을 위반한 셀들이 도착할 때 지탱할 수 있는 셀율은 평균 비트율에 가까울수록 좋은 성능을 보인다. 그리고, 약속을 지키는 셀들의 경우에는 평균 셀율보다 큰 값을 지탱할 수 있는 셀율로 선택할 때 셀 손실 확률을 감소시킨다.

In this paper, state of exploitation of world fishery resources after 10 years under the new regime in the sea, called the era of exclusive economic zone (EEZ) expending up to a 200 nautical miles from coastal line, was reviewed to determine effect from establishing EEZ in the world fishery production and its export/import volume based on the fishery statistics annually published by the Food and Agriculture Organization (FAO) of United Nation. The world total production from marine living resources had a trend showing a waned increase during 1970's when most of coastal states were translated into the reality of EEZ. From mid-1980's onwards, it increased rapidly, reaching about 85 million tons. Such increase in production was basically from the Pacific Ocean, accounting for more than 60% of the world total production. Fishing areas where showed increase in the production after the new regime in the sea were the southwestern Atlantic (FAO area 41) , the eastern Indian (FAO area 57) and the whole fishing areas in the Pacific except the eastern central Pacific (FAO area 77) . Increase in the production from distant-water fishing countries came from the regions of the southwest Atlantic (FAO area 41) and the southwest Pacific (FAO area 81) . The production from coastal states was up from the regions of the eastern Indian (FAO area 57) , the northwest and northeast Pacific (FAO areas 61 and 67) and the southeast Pacific (FAO area 87) . It was likely that the exploitation of the fishable stocks was well monitored in the areas of the northwest Atlantic (FAO area 21), the eastern central Atlantic (FAO area 34) and the northeast Pacific (FAO area 67) through appropriate management measures such as annual harvest level, establishment of total allowable catch etc. The marine fisheries resources that have made contribution to the world production, despite expansion of 200 EEZ by coastal states, were sardinellas, Atlantic cod, blue whiting and squids in the Atlantic Ocean ; tunas which mainly include skipjack, yellowfin and bigeye tuna, croakers and pony fishes in the Indian Ocean ; and sardine, Chilean pilchard, Alaska pollock, tunas (skipjack and yellowfin tuna), blue grenadier and blue whiting including anchoveta in the Pacific Ocean. It was identified that both fishery production and its export since introduction of the new regime in the sea were dominated by such coastal states as USA. Canada, Indonesia, Thailand, Mexico, South Africa and Newzealand. But difficulties have been experienced in the European countries including Norway, Spain, Japan and Rep. of Korea. Therefore, majority of coastal states are unlikely to have yet undertaken proper utilization as well as rational management of marine living resources in their jurisdiction during the last two decades. The main target species groups which led the world fishery production to go up were Alaska pollock, cods, tunas, sardinellas, chub and jack mackerel and anchoveta. These stocks are largely expected to continue to contribute to the production. The fisheries resources which are unexploited, underexploited and/or lightly exploited at present and which will be contributed to the world production in future are identified with cephalopods, Pacific jack mackerel and Atlantic mackerel, silver hake including anchovies. These resources mainly distribute in the Pacific regions, especially FAO statistical fishing areas 67, 77 and 87. It was likely to premature to conclude that the new regime in the sea was only in favour of coastal states in fishey production.
한국 동해안 용가자미 , Cleisthenes pinetorum herzensteini (Schmidt) 의 성장과 성숙
장창익,허영희,최수하,전영렬 한국수산자원학회 1999 한국수산자원학회지 Vol.2 No.-
The growth and maturity of Cleisthenes pinetorum herzensteini(Schmidt) was studied using samples caught by gillnetters from January 1992 ro December 1994 in the East Sea. Ages were determined from otokith(sagittae) surface readings. Marginal increments for al age groups of both sexes showed a single annual minimum during May, indicating that otolith surface readings were reliable estimators for age determinations of pointedhead flounder. Maximum ages observed were 7+ in females and 5+ in males. The con Bertalanffy growth equation were Lt=46.2{1-e -0.1524(t+0.5376)} for females and Lt=31.9{1-e -0.2698(t+0.1242)} for males, respectively. Predicted lengths of females were larger than those of males for all ages. The overall sex ratio(female : male) were 65:35, which were significantly different from the equality. Spawning season was February to March with a peak in February. The relationship between fecundity(F) and total length (TL,cm) was F=2,119,140/{1-e (14.89-0.477xTL)}. Total lengths at 50% group maturity were estimated to be 24.6cm for females and 21.6 cm for males, respectively.
베링해와 알라스카만 명태의 비늘과 이석에 의한 연령사정 비교
이장욱,허영희 한국어류학회 1993 韓國魚類學會誌 Vol.5 No.2
베링해 공해 및 알라스카만에서 표본된 명태의 동일 개체로부터 비늘과 이석을 사용하여 연령사정한 결과를 비교, 고찰하였다. 베링해 공해 명태 44∼54㎝ 범위의 개체에 대한 연령사정 결과, 비늘연령은 4∼9세, 이석연령은 4∼18세로 나타났다. 동일개체의 두 연령형질간에 1∼11세까지의 큰 차이를 보였으며, 특히 이식의 연령이 증가할수록 그 차이가 더욱 크게 나타났다. 알라스카만 명태 22∼59㎝ 범위의 개체로부터 비늘 연령은 2∼9세, 이석연령은 2∼11세로 나타났다. 두 연령형질간의 연령사정 결과는 6세까지는 잘 일치하였고, 7세 이상에서는 이석에 의한 연령이 1∼7세까지 높게 나타났다. Results comparing the scale and otolith ages for walleye pollock from the Donut Hole of the Bering Sea showed a significant discrepancy for fish older than 8 years old. For walleye pollock from the Shelikof Strait of the Gulf of Alaska, comparison between ages determined from the scale and otolith readings indicated that there were no differences for younger age groups, but for the ages 6 and older, discrepancies squeezed in somewhat amid the same age groups.
