김윤하,문창호,최광호,이충일,Kim, Yoon-Ha,Moon, Chang-Ho,Choi, Kwang-Ho,Lee, Chung-Il 해양환경안전학회 2010 해양환경안전학회지 Vol.16 No.3

20년간(1980-1999) 동해의 해구(위경도 $30'{\times}30'$)별 오징어(Todarodes pacificus) 총 어획량과 단위노력당 어획량(catch/gear/day, CPUE)을 분석하여, 특정 해역에서 오징어 어획량이 높은 원인을 물리(수온), 생물학적 환경 인자(동물플랑크톤 생체량)를 이용하여 분석하였다. 해구별 총 어획량과 CPUE는 1980년대보다 1990년대에 증가하였다. 20년간 평균어획량이 높았던 해구는 동해 남부 5개 해구(No. 87, 76, 82, 83, 88)이었고, CPUE가 높았던 해구는 울릉도와 울진 부근의 해구(No. 65, 71, 72, 78)로 나타났다. 동해 전체 해구에서 이들 특정 해구의 총 어획량과 CPUE가 차지하는 비율은 각각 35.1%와 62.1%였다. 총 어획량과 CPUE가 높은 해역은 쓰시마 난류의 북방한계 지표수온인 $10^{\circ}C$의 등온선의 상부 수층에 위치하였으며, $10^{\circ}C$ 등온선의 분포 위치에 따라 해구별 총 어획량과 CPUE가 다르게 나타났다. 해구별 동물플랑크톤의 생체량 분포와 오징어 어획량 간에는 높은 상관성이 나타나지 않은 반면, 전체 해구의 동물플랑크톤의 연간 총 생체량과 오징어 총 어획량의 시계열 변화 경향은 유사하게 나타났다. Data on squid catches by the Korean jig fishery in sea blocks ($30'{\times}30'$), water temperatures at depth(30m, 50m and 100m) and zooplankton biomass in the East Sea from 1980 to 1999 were analyzed to examine the mechanism of formation of the high density stock area. Japanese common squid (Todarodes pacificus) catch in the East Sea was low in 1980s, while the catch was high in 1990s. The five sea blocks (No. 76, 82, 83, 87, 88) of the southern part in the eastern coastal waters of Korea showed high levels of percentage of total catch (35.1%), whereas the four sea blocks (No. 65, 71, 72, 78) of the coastal waters of Uleung Island showed high levels of percentage of CPUE (61.2%) for 20 years. Squid catches showed monthly fluctuations according to the vertical distribution of optimum water temperature for fishing ($14^{\circ}C{\sim}19^{\circ}C$). High total catch and high CPUE area matched well with $10^{\circ}C$ isothermal lines at 100m depth indicating northern limiting of Tsushima Warm Current, and temporal and spatial change in $10^{\circ}C$ isothermal line caused the change in total catch and CPUE. Horizontal distribution of zooplankton biomass by sea block was not matched well with those of total catch and CPUE, however pattern of time-series change in total zooplankton biomass was similar to that in total squid catch.

기후변화에 따른 살오징어(Todarodes pacificus) 산란장 환경 변화

This study analyzed the influence of climate change on the spawning ground area of the common squid, Todarodes pacificus. To estimate long term changes in the area of the spawning ground of the common squid, water temperature at 50 m deep that can be inferred from sea surface temperature (SST) based on both NOAA/AVHRR (1981.07-2002.12) and MODIS/AQUA (2003.01-2009.12) ocean color data was analyzed. In addition, five climate indices, Arctic Oscillation Index (AO), Siberian High Index (SH), Aleutian Low Pressure Index (ALP), East Asia Winter Monsoon Index (EAWM) and Pacific Decadal Oscillation (PDO) which are the main indicators of climate changes in the northwestern Pacific were used to study the relationship between the magnitude of the estimated spawning ground and climate indices. The area of the estimated spawning ground was highly correlated with the total catch of common squid throughout four decades. The area of the estimated spawning ground was negatively correlated with SH and EAWM. Especially, PDO was negatively correlated with the area of the spawning ground in the northwestern Pacific (r = -0.39) and in the southern part of the East Sea (r = -0.38). There was a positive relationship between the AO and the area of the spawning ground in the northwestern Pacific (r = 0.46) as well as in the southern part of the East Sea (r = 0.32). Temporally, the area of the winter spawning ground in the southern part of the East Sea in the 1980s was smaller than those areas in the 1990s and 2000s, because the area was disconnected with the western coastal spawning ground of Japan in the 1980s, while the area had been made wider and more continuous from the Korea strait to the western coastal water of Honshu in the 1990s and 2000s.

자유주의와 공동체주의 논쟁의 도덕교육적 의의(Ⅱ)

This study aims to investigate different viewpoints, supplementary relationships, and possibility of intergration of moral education by analyzing the educational debates betweenb the liberalism and the communitarianism. According to individualism, education ought to be understood from the point of view of individual right and freedom. Also the aim of education ought to be in strengthening rational autonomy. They emphasize, first of all, the cultivation of individual moral judgment and value selecting ability in moral education. However, communitarianism assumes that human being forms one's existence throughout participating in community living. Communitarianism sees education as intersubjective and collaborative activities. So it emphasizes the traditional culture and virtues as educational contents, and the cultivation of good citizenship as educational aim. Communitarianism insists that fostering of community consciousness and pursuit of common good are aims of moral education, and virtues can prevent abstraction and emptiness of individualism's moral theory which only insists on formal moral principles. After summing up briefly the educational debates between the liberalism and the communitarianism, I debated the tension between good man and good citizen, rational outonomy and community consciousness, formal moral principle and virtues (common good), and individualized learning and collaborative studying. In conclusion, future moral education needs to combine traditional ethics of Sittlichkeit and modern ethics of individual rights in long term perspectives. It also needs to have dialectic relations with the ethics of procedural and character through harmonization of individual virtues and communal virtues.

식물생장조절물질 처리가 서양민들레 종자 발아에 미치는 영향

김윤하,이인중 한국잔디학회 2013 Weed & Turfgrass Science Vol.2 No.2

Dandelion (Taraxacum officinale) is a member of family Asteraceae that grows all over the Korea. Recently, dandelion was cultivated for medicinal crops because of its positive medicinal effects. However, dandelion is considered as a troublesome weed in grass lawns of golf course and orchards. This study was conducted to investigate the effect of plant growth regulators [gibberellins (GA3); kinetin; salicylic acid (SA); ethephon)] with different concentration on seed germination control of dandelion. Seed germination rates were increased in all concentration of GA3 and kinetin treatment compared to control. In the 0.5 mM of ethephon application, seed germination rate was more increased than that of control while seed germination rate was reduced in 1.0 and 1.5 mM of ethephon treatments. Seed germination rate was significantly decreased with different SA dilutions compared to control. The germination rate was more reduced when SA was applied in combination with GA3 than only SA treatments. 서양민들레는 국화과 식물로서 한국 전역에서 자생하고있다. 최근에는 서양민들레의 효능으로 인해 최근 약용식물로 재배되고 있다. 그러나 서양민들레는 골프장 잔디밭이나 과수원에서는 잡초로 고려되고 있다. 본 실험은 다른 농도의 식물생장조절물질[gibberellins (GA3); kinetin;salicylic acid (SA); ethephon)] 처리가 서양민들레 종자발아율에 미치는 영향을 조사하기 위해 수행하였다. 실험결과, GA3및 kinetin 처리 모든 농도에서 무처리에 비하여종자발아율이 약 24.2~41.9% 높았다. Ethephon 0.5 mM의처리에서는 무처리에 비해 종자발아율이 7.5% 높았으나,1.0 및 1.5 mM 처리에서는 약 11~22% 가량 낮은 경향이었다. 반면에 SA와 GA3의 혼합처리 경우에는 했을 때 종자발아율은 SA 단독처리보다 더욱 낮았다.

Physicochemical properties and oxidative stability of corn oil in infrared-based and hot air-circulating cookers

김윤하,김미자,이재환 한국식품과학회 2022 Food Science and Biotechnology Vol.31 No.11

Corn oil was heated using an infrared cooker, an air fryer, and a cooking oven at similar temperatures, and oxidative stability and physicochemical properties including moisture content, temperature change, the profile of headspace volatiles, formaldehyde and acetaldehyde of the heated oils were compared. Corn oil heated using the air fryer showed the lowest degree of oxidation, followed by that heated using the infrared cooker and the cooking oven. However, the content of headspace volatiles in 120 min heated oil using the infrared cooker was higher by 2.57 and 5.37 times than that in oil heated using the cooking oven and the air fryer, respectively. The profiles of formaldehyde and acetaldehyde in oils showed patterns inconsistent with those of headspace volatile and oxidation parameters. Generally, the air fryer-treated oil underwent slow lipid oxidation, whereas oil from the infrared cooker had more volatiles and imparted odor to foods.
