평화를 전쟁의 부재라고 정의할 때 현재 전쟁이 없다면 지금 이 시간은 안전하고 평화로워야 한다. 그러나 지금 현 세상은 비록 공식적으로 선포된 전쟁은 없다고는 하지만 그래도 결코 평화롭다곤 할 수 없을 것이다. 흑해의 크림반도가 노골적인 군사적 침략이 없었지만 결과적으로 러시아의 수중에 떨어졌다. 남중국해의 여러 섬이나 암초들이 정규 군사작전 없이 사실상의 중국의 소유로 기정사실화 되고 있다. 전시 군사적 침략을 통해서만이 확보 가능한 전략적 목표들이 전시도 아니고 그렇다고 평시도 아닌 어중간한 시기에 적 또는 상대의 수중에 떨어지고 있다. 즉, 전시와 평시 사이의 회색지대에서 소위 회색지대전략이라고 부르는 공세적 전역을 통해 이러한 전략적 목표들이 달성되어 지고 있다. 소시지가 너무 커 한입에 다 먹을 수 없으면 잘게 썰어 하나씩 먹으면 결국 전체를 다 먹을 수 있듯이 소규모의 절차적 행동을 단계적으로 실행, 대규모 전투를 통해서만이 확보 가능한 거대하고 중대한 목표를 확보하는 게 회색지대전략의 한 특징이다. 이를 전략적 점진주의(strategic gradualism)라고 한다. 또한 단계적 행동은 누구나 인지할 수 있지만 그러한 점진적 행동의 결과에 대해선 쉽게 간파할 수 없기 때문에 대응자의 입장에선 대부분 특별한 대응책을 세우지 못하고 방치하고 만다는 게 이 전략의 또 다른 특성이다. 즉, 회색지대전략은 특성상 반드시 애매모호성(ambiguity)을 띄고 있다는 것이다. 회색지대에서의 도전자의 행위는 일종의 속임수일 수도 있다. 전략의 본질은 위계, 즉 상대로 하여금 오인, 착각, 부지를 일으키도록 하여 소기의 목적을 달성하는 것이다. 그래서 회색지대전략(gray zone strategy)이라고도 한다. 양육강식의 논리가 작용되는 현실 세계에선 힘이 곧 정의이고 국익이 최고의 선이다. 국가이익은 오직 과정보다는 결과만을 놓고서 정당화된다. 이에 회색지대전략에서도 결과에 대한 유용성만 거론되지 과정상 불법성이나 비도덕성 등은 따지지 않는다. 대부분 이 전략의 애매모호성 때문에 과정 자체를 식별하기가 쉽지 않다. 그래서 대응자의 입장에서도 사전에 예방할 수 있는 선제적 대응전략을 구사하기가 어려운 게 사실이다. 한국도 예외가 아니다. 중국이 해상민병을 이용한 회색지대전략을 구사, 이어도에 대한 도발을 감행할 수도 있다. 일본이 민간 극우파 등을 이용한 회색지대 전략을 구사, 독도에 대한 도발을 감행할 수도 있다. 평화는 거저 존재하지 않는다. 확전을 각오한 사전대비차원의 억지책이 마련되어야 상대의 회색지대전략을 단념시킬 수 있다. 그것도 신뢰성 있는 억지력만이 진정한 평화를 담보할 수 있다. 전략이 있어야 대응계획을 세울 수 있고, 상대는 이럴 때 도발을 단념하게 된다. 대응전략이 없다는 것은 대응계획이 없다는 것을 의미하고, 이러한 무계획은 늘 실패만을 계획하고 있다는 것을 명심해야 할 것이다.

Heavy metals in the surface seawaters and sediments were measured in Gaduk channel of jinhae Bay. The high concentrations of heavy metals in the seawaters were found at the stations near the islands. In the seawaters, the mean concentrations of dissolved heavy metals except for Pb were not higher than previous data in this bay. Higher heavy metal contents in the surface sediments were observed at the stations adjacent to the Geojedo or Gadukdo of the Gaduk channel. The contents of Co,Ni,Zn,Cu,As and Cd in the surface sediments showed relatively high correlation coefficients with IL and COD. The order of enrichment factors(EFs) of heavy metals in the sediments on the basis of average shale values was As>Cd>Pb>Zn>Co>Cu>Hg>Ni, and the EFs of As,Cd,Pb and Zn at whole stations were higher than 1. EFs of Ni and Zn on the basis of natural background concentration in Korean coastal sediments were lower than EFs by average shale.

The everyday life of police officers requires them to face a number of criminal acts and enter compromising crime scenes. In this case, officers may be compelled to make a personal expression of negative emotions. Negative emotions of members confidence for effective job processing and contributions duties and achievement of the job within the marine police force. Therefore, to control the emotive dissonance of organization members is a great help to the development of the organization. This study focuses on emotional dissonance among marine police officers to verify the impact of this dissonance on job burnout and consider the mediating effect of emotional intelligence. Research results are as follows: First, the relationship between emotional dissonance sub-factors and job burnout among marine police officers was studied. It was found that marine police did not feel emotionally jarred because they consciously tried to abstain from emotional engagement, but this was found to reduce emotional intelligence as related to desired emotions as well. Second, Emotional intelligence of the Marine Police was found on a significant impact on job burnout. Third, the impact of emotions in relation to emotional dissonance that job burnout of marine police intelligence officials confirmed that there is a statistically significant mediating effect. Finally, in a comparison of direct effects versus mediated effects, marine police were seen to be prone to emotional dissonance and experienced job burnout as a direct result of applying greater emotional intelligence.

Some coastal oceanographic investigations in Kwang Yang Bay were carried out bimonthly from April to September (The first half period of the research project) in 1974. The behaviour of the waters, distributions of water temperature and salinity and diffusion characteristic by dye release experiments in the bay are studied for the problems of practical importance in connection with water pollution. Velocities and directions of tidal currents at five fixed stations were observed. And dye diffusion experiment was also carried out on the sea. According to the results from this study, the salinity of the water is lower, ranging from about $28\;\textperthousand\;to\;32\textperthousand$, on all over the surface in the bay with the cause that the fresh water flows in from the Sumjin river. Diffusivities in this sea by means of Rhodamine B diffusion elliperiment were $785.6\;{\times}\;10^2\;\textrm{m}^2/sec$ in major axis, $15.6\;{\times}\;10^2 \;\textrm{m}^2/sec$/sec in minor axis in the direction on patch after 30 minutes from the dye release.

To understand the attachment of micro algae and their subsequent growths on artificial surfaces immersed in seawater, the relationship between attachment of diatoms on the immersed artificial substrates and species pool in the surrounding water was investigated. We used acryl slides for the study of diatom attachment and examined the surrounding water samples collected in Incheon Harbour from July 1995 to February 1997. Variations of species composition and abundances by exposure time in seawater were investigated during the early phase of biofilm formation on various substrates, e.g. glass, acryl, titanium, copper and antifouling paint-treated slides. Immigration rates of diatoms to acryl slides during spring and winter were significantly correlated with the abundance of benthic diatoms in surrounding water ($r^2$=0.78, p<0.01, n=42), suggesting that immigration rates were affected by variations of benthic diatom abundances in surrounding water. Immigration coefficient of monoraphid diatoms was 5 times higher than that of biraphid diatoms, but relative abundance of monoraphid diatoms was 3 times lower than that of biraphid diatoms on acryl slides in spring. In winter, immigration coefficient and relative abundance of centric diatoms were higher compared to other raphe forms. These results suggest that the attachment of diatoms seems to be caused by the abundance and immigration coefficients of benthic diatoms in surrounding water. Pennate diatoms predominantly attached to all artificial surfaces throughout all experimental periods. Interestingly, centric diatoms predominantly attached to all artificial surfaces in winter. Hantzschia virgata, Licmophora abbreviata and Melosira nummuloides appeared dominantly on antifouling paint-treated slides, probably being tolerant of the antifouling paint. During incubations, the abundance of attached diatoms increased exponentially on glass, titanium and acryl slides with exposure time. The maximum abundance was highest on glass slide, followed by acryl, titanium, copper and antifouling paint-treated slides. The growth rates of attached diatom community on all artificial surfaces were higher at temperature of $24-25^{\circ}C$ than that of $2-3^{\circ}C$. The growth rate of attached diatoms on glass slide was generally higher compared to other slides during the study period. Dominant morphotypes of observed species with exposure time in seawater were prostrate form Amphora coffeaeformis, fan shape Synedra tabulata, stalk type Licmophora paradoxa and chain type M. nummuloides. A micro-succession in the attached microalgal community was observed. The composition of dominant species seems to be the result of species-specific response to gradually limited space with development of microalgal film.

The community structure and micro-scale distribution of plankton in relation to hydrography were investigated in Masan Bay, Korea in October 1989. Warmer and less saline waters with stratification was located in the inner part of the Pudo Strait, and chlorophyll-a and nutrients were higher. Both phytoplankton biomass and nutrients was changed dramatically around the Strait. Offshore/oceanic species in phytoplankton i.e., Chaetoceres decipiens, Rhizosolenia stolterforthii, Rhizosolenia styliformis and Ceratium trichoceros and zooplankton i.e., Sagitta enflata, Oncaea uenusta and Oikopluera longicaudata occurred mainly in well mixed waters of the outer part. This suggests that discontinuous layer seems to play an important role as an approximate border for the plankton population. This layer was located between Station 3 and Station 4 near the Pudo Strait, since the layer consisted of a series of micro-scale discontinuties of salinity and dissolved inorganic nutrients gradient. Phytoplankton patchs of more than 801e1 were found only in the inner part of the bay. Depletion of silicate caused by a rapid assimilation of phytoplankton in the inner part of the bay seemed to be responsible for the decline of blooms.

Field survey on the variational characteristics of water quality and chlorophyll a concentraion were carried out at the 25 stations for four seasons in Kogum-sudo(Straits) southern coast of Korean Peninsula from Feburuary to October in 1993. We made an analysis on biological factor as chlorophyll a concentraion as well as physicio-chemical factors such as water temperature salinity sigma-t transparency dissolved oxygen(DO) chemical oxygen demand(COD) nutrients (ammonia, nitrite, nitrate, phosphate, and silicate) N/P ratio and suspended solid(SS). The waters in the Kogum-sudo were not stratified due to the tidal mixing. And the high productivity in photic layer were supported by high nutrients concentration from bottom waters. The high concen-trations of suspended solid in straits had a bad influence upon marine biology of nature and cultivations. In Kogum-sudo had a sufficient nutrients for primary productivity during a year. Especially phosphate and inorganic nitrogen were high the other side silicate was very low. The source of nutrients supply depend on rather mineralization of organic matters and input of seawater from outside than input of freshwaters from lands. Phytoplankton biomass as measured by chlorphyll a concentratiion was very high all the year round and it was controlled by the combination o f several environmental factors especially of phosphate in summer and dissolved nitrogen in other seasons.

The fairway within the area of Yul-do and Songdo located near the Myeongnyang-sudo approaches south of Mokpo harbor is well guided by traffic separation scheme and other navigational aids. However, that part of the waterways where Yul-do is located sits at the cross-roads of marine traffic and is subjected to some potential risks in the voyage navigation: the effect of climatic phenomenon, the disregard of most ships in using the western sector of the fairway creating a congestion in the eastern sector, and lastly, the disadvantageous erect of the location and height of Yul-do island that hinders good lookout. This study investigates the environmental conditions that prevailed in the area in the span of 5-year period and the marine traffic situation taken from the data within the 72-hour period The navigational hazards and marine casualties are also be presented. The results are analyzed and are made the basis of a proposal for an improved separation of traffic. Thereafter, an evaluation is carried out by using the components of marine traffic flow simulation and ES modeling index. It is evaluated through simulation by the use of full-mission ship handling simulator.

Stable isotope ratios of oxygen and hydrogen were investigated in southern Yellow Sea in August 1997. Salinity showed good positive correlation with ${\delta}^{18}$O and ${\delta}$. The correlation between ${\delta}^{18}$O and ${\delta}$D is good. From the relationship between these parameters, we obtained two lines of conclusion: 1) seawater of study area I in summer is a mixture of Changjiang Water and modified Kuroshio Water; 2) stable isotopes are very useful tracers in studying property and behavior of water masses in the study area. In case when water masses can not be easily distinguished by T-S analysis, the stable isotopes seem to be powerful tools for this purpose.
