This paper describes the relationship between the distribution of fishing ground and E1 Nino events in the pacific Ocean which have occurred on a regular basis of 3-5 year terms. Anneal catches and catch ratios of skipjack. Katsuwonus pelamis and yellowfin tuna. Thunnus albacares largely increased during El Nino years due to the increasing of accessibility in accordance with the eastward extend of fishing ground, but vice versa during La Nina years. It is suggested that during El Nino years, the fishing grounds of Korean tuna purse seine fishery were extended to eastward in associated with the eastward advection of warm pool which was located in western equatorial Pacific Ocean during the normal state and characterized by the over 28℃ and low nutrients water masses.

This paper describes the relationship between the distribution of tuna and ENSO events in the Pacific Ocean which have occurred on a regular basis of 3-5 year terms. Annual catches and catch ratios of skipjack Funa, Katswonus pelamis and yellowfin tuna, Thunnus albacares largely increased during El $Ni\~{n}o$ years, while it decreased during La $Ni\~{n}a$ years. However, the effect of El $Ni\~{n}o$ on the distribution of tuna seemed to be more significant to yellowfin tuna which usually occurr the upper thermocline depth increases due to the elevated thermocline in the Western and Central Pacific Ocean.

We conducted experiments to compare the catch rate of bigeye tuna and yellowfin tuna between circle hooks and straight shank hook in the Korean tuna longline fishery at the eastern and central Pacific Ocean from 2005 to 2007. We analyzed difference of fork length, survival and hooking location between a circle hook and a straight shank hook for both tunas, respectively. There was no difference in the mean fork length size of yellowfin tuna caught on the two type of hook but bigeye tuna was significant. In case of survival, there was no difference between two hook type, but the difference of hooking location was significant for both species. We also analyzed to find determinants of both tunas catch rate using generalized linear models (GLMs) which were used latitude, longitude, year, month, depth, hook type, bait type and so on as independent variables. Spatial factors, latitude and longitude, and temporal factors, year and month, affected catch rate of bigeye tuna and yellowfin tuna. And also, depth such as a marine environment factor was influenced on catch rate.
Using Light in for PIN Entry Authentications
안두리(Andrea Bianchi),이안오클리(Ian Oakley),권동수(Dong Soo Kwon) 한국HCI학회 2012 한국HCI학회 학술대회 Vol.2012 No.1
Performing sensitive authentications, such as ATM PIN entry, in public spaces is a commonplace activity that is inherently susceptible to security attacks based on observation in person or via cameras. This paper addresses this problem with a system which allows users to enter PINs on their mobile devices and then transmit them securely for authentication using modulated patterns of light shown on the screen, sensed by a receiver unit and initiated by a physical action (placing the device facedown on the receiver). The advantages include the use of standard mobile devices and low cost sensing hardware. Furthermore, no pre-pairing is required as physical proximity guarantees security.
국제포경위원회 연례회의 기조연설 분석을 통한 대한민국 정부의 포경 입장 연구
손호선,안두해,안용락 한국해양수산개발원 2015 해양정책연구 Vol.30 No.1
The stance of the Korean government on the whaling issue is analyzed by its opening statements in the annual meetings of the International Whaling Commission(IWC) since 1978. The analysis shows that, in spite of the variable tones of the opening statements, the Korean government has consistently stated to catch whales within its Exclusive Economic Zone. But it is not probable to resume commercial whaling because of the confrontation between pro- and anti-whaling group in the IWC. Asking commercial whaling only in the opening statements could not make a breakthrough in the stalled IWC, and give any benefit to the Korean government. Neutral statement balanced between pro- and anti-whaling would make more whaling opportunities to the Korean government.
해양포유류 보호를 위한 수중 소음 관리 제도 도입 방안
손호선,안두해,김현우 한국해양수산개발원 2015 해양정책연구 Vol.30 No.2
Increased human activities in the marine environments have caused the increase of anthropogenic underwater noise in the oceans. Many countries are concerning about the harmful effects on marine mammals derived from the noise, and have legal frame to manage the negative noise effects on the marine environments. Korean government is planning to construct large offshore wind farms off the west and south coast of Korean peninsula and around Jeju island. There has been no laws and policies about the underwater noise management to protect marine mammals in Korea. This paper reviewed the guidelines by U.S. National Oceanic and Atmospheric Administration to assess the effects of anthropogenic sound on marine mammal hearing, and assessed the impacts from the construction of wind farms off Jeju island on the Indo-Pacific bottlenose dolphins inhabiting the area. Finally the recommendations to establish proper legal frame for the management of the underwater noise in Korean waters are given. 해양에서 인간 활동 증가로 인해 수중 소음 또한 크게 증가했으며, 대한민국 정부는 해상 풍력 발전 산업을 미래 유망 산업으로 규정하고 그 규모를 확대할 예정이다. 하지만 건설 및 운영 단계에서 발생하는 소음 에 대한 법적 관리 체제는 전무한 실정이다. 건설 공사 등으로 발생하는 강한 수중 소음은 어류를 비롯한 해양생물의 행동과 생리 등에 변화를 일으키고 심할 경우 청각 기관 등에 물리적 손상을 일으키기도 한다. 특히, 소리를 수중 이동 감각, 개체간 소통 및 먹이 활동을 위해 사용하는 해양포유류, 특히, 고래류는 주변의 소음에 크게 영향을 받기 때문에 많은 국가들이 수중 소음에 대한 규제를 실시하고 있다. 본 논문에서는 미국의 해양포유류 보호를 위한 수중 소음 관리 제도를 검토한 뒤, 제주도 풍력 발전 단지 건설과 운용에 따른 수중 소음이 남방큰돌고래에 끼치게 될 영향을 예측하고, 이를 바탕으로 대한민국의 수중 소음 관리 방안에 대한 제안을 한다.
국제사법재판소의 일본 남극 조사포경 불법판결에 따른 한국의 고래자원 관리 정책 방향 제안

On March 31, 2014, the International Court of Justice(ICJ) judged that the current Japanese Antarctic scientific whaling program did not fall within the provisions of Article VIII, paragraph 1, of the International Convention for the Regulation of Whaling. As a result ICJ asked Japan to revoke any extant authorization, permit or licence granted for scientific whaling. Japan accepted the decision immediately, but announced that a new scientific whaling plan would be submitted to the International Whaling Commission(IWC). Because the ICJ judgement is confined to the current Antarctic whaling, Japan’s North Pacific scientific whaling program is still in operation. The ICJ ruling acts as a guide for Japan’s future scientific whaling program rather than signalizing the collapse of the program. The Japanese whaling program is not driven by economic motives, but rather by cultural motives. To uphold their traditions, the Japanese government intends to continue its whaling program in spite of the international opposition. Korea has attempted to conduct scientific whaling twice, in 1986 and in 2012, but abandoned the plans due to strong opposition by the IWC members. Korea wants to resume whaling within the IWC’s legal frame work, rather than in the controversial Japanese scientific whaling approach. Considering the whaling quota allocation program in IWC, scaling up the current sighting survey to reduce uncertainty in the abundance estimates, and strictly managing incidental whale catches in Korean waters would better ensure the Korean government could obtain the IWC quota. Fostering the whale watching industry, reducing the conflicts between fishermen and dolphins, and further developing international research cooperation are also recommended to accomplish sustainable management of the cetacean resources in Korean waters. 2014년 3월 31일 국제사법재판소는 일본의 남극 조사포경이 ‘과학 조사를 목적으로 한’ 경우에 포경을 허용하는 국제포경규제협약을 위반했으므로 즉시 중단하라고 판결했다. 일본 외무상은 판결 직후 이를 수용하겠다고 발표했지만, 새로운 조사포경 실시를 예고했다. 위 판결로 인해서 형성된 조사포경을 비롯한 포경에 대한 반대 분위기 속에서 개최된 제65차 IWC 총회에서 대한민국 정부는 포경 재개를 희망한다고 발표 했다. 본 논문은 이상에서 언급한 판결의 세부 내용, 여기에 대한 일본 및 반포경 국가들의 반응과 일본의 향후 대응 계획을 알아보고, 이를 통해 대한민국의 고래 자원 관리 정책 방향을 제안하고자 한다.
