에스트로겐성 내분비계장애물질들은 하수처리장, 폐지공장, 농장의 폐수 등을 통해 수계생태계로 들어간다. 이들 물질들은 estrogenic 잠재력과 어류에서 estrogen 합성에 영향을 미치고(Jobling ad Sumpter, 1993), 에스트로겐적인 활성의 중요한 요인이되어 (Desbrow et al., 1998; Ternes et al., 1999; Baronti et al.,2000) 어류의 난발생과 생식기능에 영향을 미치게 된다. (중략)

몇해전 IMF라는 불청객을 안방으로 끌어들일때 우리 국민들의 심정은 그 무엇으로도 위로가 되지 않는 패닉의 상태였다. 암울한 시기에 국민 경제에 하나의 희망으로 등장한 것이 바로 벤처기업이었다. 일부의 벤처기업들은 절망 속에서 오히려 성장을 하면서 희망의 메시지를 던졌다. 코스닥에 등록된 벤처의 주가는 천정부지로 치솟았고 젊은이들의 벤처러시를 이루었다. 몇해후 벤처 거품론이 등장하면서 코스닥 주가상승도 멈칫 거리기 시작했다. 정부 또한 정확한 진단없이 벤처열기를 부추긴 것은 사실이다. 벤처에 대한 정확한 진단이 없기는 지금도 마찬가지다 너무 많은 수의 닷컴기업들이 난립하고 있기 때문에 정확한 통계 산출의 어려움이 있을 수 도 있다.

From March 1998 to April 2000, 4 species of marine fishes including black rockfish (Sebastes schlegeli), goby (Acanthogobius flavimannus), fine-spooted flounder (Pleuronichthys cornutus), and croaker (Nibea albiflora) were captured from the coastal area of the Gogunsan island located in the mouth of the Kum River, and greenling (Hexagrammos otakii) was sampled from the coastal areas of the Gogunsan island and the Wan-do. Trematodes from the stomach and the intestine of the fishes were detected and identified on the basis of the morphological characteristics. Four species of trematodes were detected in the stomach and the intestine of the examined fishes ; Opecoelus lobatus Ozaki, 1925 from black rockfish, fine-spotted flounder and greenling, Coitoecum glandulosum Yamaguti, 1934 from goby, Phyllodistomum sp. Braun, 1899 from croaker, and Pharyngora sp. Lebour, 1908 from greenling captured from Wan-do. This report gave morphological descriptions of O. lobatus, Pharyngora sp. and Phyllodistomum sp. from coastal marine fishes in Korea.

Thirty five catfish (Silurus asotus) cultured in a fish farm of Jungeup and 222 wild goby (Acanthoguobius flavimanus) caught from the estuary of Mankyoung River, Chonbuk province of Korea were examined the prevalence of myxosporidian infestation. A lot of white spherical myxosporidian cysts in the intestinal epithelium of catfish and the muscle of goby were easily found. The cysts in size were 56 × 73 (42-77 × 59-93 ㎜) in catfish and 2.43 × 0.95 ㎜ in goby. The infection rate (%) were 88.4 in catfish and 89.4 in goby. The Myxosporidians from the intestine of catfish and from the musculature of goby were identified as Myxoborus miyairii and Henneguya tridentigeri on the basis of the shape and structure of the spores under a light microscope. imensions (㎜) of fresh spores of Myxoborus miyairii: length, 11.0-12.0; width, 5.0-6.0; thickness, 3.5-4.0; polar capsule: length, 5.0-5.5; thickness, 1.5-2.0; polar filament: length, 40-45. Dimensions ($\mu{m}$) of fresh spore of Henneguya. tridentigeri: length, 10.0-12.0; width 6.0-8.0; thickness, 4.8; polar capsule: length, 4.6; thickness, 2.6; iodinophilic vacuole: 2.8 × 2.4. No significant pathological change was found from the infected fish. This is the first report on M. miyairii and H. tridentigeri from fish species in Korea.

This study conducted in-depth interviews of seven parents with autistic adults and analyzed them using qualitative case study methods in order to understand overall meaning of care experiences of parents with autistic adult children. Thus, four key topics which are 'experience of embracement', 'experience of anticipation', 'experience of despair', 'experience of resistance' were constructed. Under these key topics, 12 subcategories which are 'accepting reality', 'positive experience', 'gradual improvement', 'desire to provide better quality of life', 'expectation towards the society', 'strenuous lives', 'psychological exhaustion', 'predicted anxiety', 'defensive attitude', 'distrust of social welfare', 'confronting injustice', 'active behaviors' were constructed. According to the analysis, care experiences of parents with autistic adults are not segmentary, but they are intertwined which make them more dynamic. Thus, easing their despair, empowering positiveness to them, and assisting them to have healthy resistant voice are needed to support the parents with autistic adults. Based on the analysis, we suggest an intervention plan to support autistic adults and their parents.

Osteological characteristics of skull, shoulder girdle, pelvic girdle, vertebrae, and pterygiophore of the four members of the genus Acanthogobius are described and compared. Characteristics of the metaterygoid, branchiostegals, urohyal, scapular, and pterygiophores that have been used to classify gobioid fishes were not different between the four species. However, ossification of the lacrymal and the number of ossified gill rakers differ from one Acanthogobius species to another. A. flavimanus is distinguished from its congeners in the size of the medial ethmoid, the number of caudal vertebrae, and the distance from left to right lateral ethmoid. A. lactipes has a large basihyal, and A. luridus has a wide distance from left to right lateral ethmoid: these are among the unique characters that distinguish them from other members of the genus. A. elongata differs notably from its congeners in the number of premaxillary and dentary teeth, the shape of the epural, and the length of the cranium.

Species composition and seasonal variations in abundance of fishes in the Nakdong River estuary were investigated using an otter trawl seasonally from September 2001 to July 2002. These data were compared with those obtained before the construction of the estuary barrage in 1987. A total of 3,648 fishes that comprised 30 species in 21 families were collected. Acanthogobius flavimanus and Leiognathus nuchalis predominated, and they were responsible for $71.2\%\;and\;67.8\%$ in the number of individuals and biomass, respectively. The next abundant fish species were Platycephalus indicus and Liparis tanakai. Compared with data obtained before the construction of the estuary barrage in 1987, abundances of Acanthogobius flavimanus, Platycephajus indicus, Liparis tanakai, Tridentiger trigonocephalus and Lateolabrax japonicus increased, while those of Pholis fangi, Repomucenus valenciennei, Sardineila zunasi and Scomber japonicus decreased. These results seems to be related to change of sediment environment caused by irregular discharge of freshwater with variation of sea water movement in the Nakdong River estuary.

소자본 투자로서의 자판기 사업은 매력적인 영역이다. 최소의 투자로도 부업을 시작할 수 있다는 점이 최대 강점으로 작용한다. 그래서 돈 많은 사람들이 자판기 운영사업에 투자하는 경우보다 주로 서민들의 투자 비중이 높은 특성을 갖는다. 그렇다보니 대개의 자판기 사업정보는 서민을 주 타깃으로 삼고 있다. 그들의 내재된 투자심리를 최대한 수면위로 끌어 올리는 일이 자판기 마케팅의 핵심이다. 소비자 입장에서 보면 알찬 부업에 투자를 해서 기대 수익을 충족시킬 수 있다면 더할 나위가 없을 것이다. 하지만 반대의 경우에 있어 문제가 생긴다. 특히 판매처의 악의적 사기에 가까운 영업행위로 피해를 보게 된다면 소비자의 분노와 절망은 클 수밖에 없다. 지난해부터 이러한 소비자 피해가 크게 늘고 있다. 순진한 소비자들이 그저 업체가 부풀려 제공하는 사업정보에 현혹되어 큰 피해를 보는 경우가 다반사로 발생하고 있는 것. 이제는 소비자들도 자판기 사업성을 제대로 보는 안목을 가져야 할 때이다. 적어도 사기성 짙은 업체와 품목은 가려서 투자할 줄 아는 안목이 있어야 리스크 요인을 최소화할 수 있다. 이러한 취지 하에 소비자 입장에서 자판기 사업정보를 접할 시, 유의할 사항들을 정리해 봤다. 이런 사항들만 조심해도 크게 피해를 보는 경우는 없을 것이다.

Hypoxic(oxygen-deficient) water masses are a key threat to the ecosystem of shallow marine coastal areas worldwide. The phenomena of hypoxia occurred at Gamak Bay, on the southeast coast of Korea, in late June 2007. In this paper, the physicochemical characteristics of seawater were surveyed for a period of hypoxic water mass disappearance. The hypoxic water mass was located between Sunso and the northwestern area of the inner bay. The dissolved oxygen(DO) concentrations of surface and bottom water were $1.3mgL^{-1}$ and less than $2mgL^{-1}$, respectively, in the hypoxic water masses, and $4.5{\sim}6.8mgL^{-1}$ and $3.8{\sim}6.0mgL^{-1}$ at the other oxygen-rich sample sites, respectively. Chlorophyll a concentrations were $4.9{\sim}25.3{\mu}gL^{-1}$ at the surface, $2.3{\sim}23.1{\mu}gL^{-1}$ in the middle, and $1.9{\sim}9.0{\mu}gL^{-1}$ at the bottom of the hypoxic water masses. When the hypoxic water mass appeared in Gamak Bay, it formed three different vertical types. The first type occurred throughout the water depth around Sunso. The second type developed from the bottom. The third type of hypoxic water mass was formed in the middle water layer when the inversion of water temperature occurred. The third type of phenomena appeared at only St. 9, St. 14 and St. 21 sites near the Hodo coast. Aquatic surface respiration of bottom-dwelling fishes such as the oriental goby(Acanthogobius flavimanus) was observed and many crustaceans were seen along the adjacent shore of the hypoxic water mass area. About 3,000 oriental gobies as well as many crustaceans died due to this event in Gamak Bay. The results of this study could provide fundamental data for the mechanism of hypoxic water masses in Gamak Bay.

This study purposes to explore the growing process through spousal bereavement in later life, and to develop the theory. A qualitative research was conducted, and the participants were 17 seniors. The analysis according to Strauss and Corbin's grounded theory(1998), resulted in 143 concepts, 43 subcategories, and 19 categories. Range analysis according to paradigm showed that the causal conditions were 'marital relationships', 'independent/dependent tendencies', and 'emotional readiness for the death of a spouse', and the phenomena were 'depression', 'hopelessness', 'daily stress', 'psychological intimidation', 'regret', and 'sense of being freed'. The contextual conditions that affect these phenomena were 'desire for intimate personal relationships' and 'desire to maintain independence'; the action/interaction strategies to manage the phenomena were 'facing reality' and 'efforts for construction of the new life'; and the mediating conditions that promote or suppress these action/interaction strategies were 'social support' and 'spirituality'. The results were 'reconstruction of the meaning in life', 'increase in self-esteem', 'reinforcement of social network' and 'embrace and acceptance'. Furthermore, when personal growth after bereavement of a spouse was analyzed focusing on changes over time, the growth process consisted of three steps: 'sadness and despair', 'embracing and moving forward', and 'personal growth'. The pattern analyses were performed to typify recurring relations by category, and 5 types were derived. The results of our study show that personal growth after spousal loss is an integrative process in life after crisis, and can be conceptualized as the process of overcoming the despair that immediately follows the death of a spouse, seeking a new life by actively taking control, and discovering a strengthened self.
