저마다 가슴속에 품었던 '그리움'이 사란진 뒤 존재 자체에 대해 갖는 의문은 존재를 분산시키기도 방황하게도 한다. 그 여정의 괴로움으로 김영현은 어떤 신비로운 존재자에 숨고자 하기도 하고, 호영송은 비생산적인 연애행각으로 시간을 낭비하기도 한다. 그들 모두 '존재하지 않는 어떤 것'에 대한 향수를 버리지 못하고 있다.

Fish assemblage structure in a sheltered shallow water in the Southern Coast of Korea was examined monthly. Sampling was conducted in Doam Bay using a beam trawl between March 2001 and February 2001. A total of 53 fish species from 33 families were caught. Pinkgray goby (Chaeturichthys hexanema), ponyfish (Leiognathus nuchalis) and yellowfin goby (Acanthogobius favimanus) were the most frequent species, comprised 67.4％ of the total numbers captured. Snailfish (Liparis tanakai), yellowfin goby (Acanthogobius flavimanus) and pinkgray goby (Chaeturichthys hexanema) represented 50.8％ of the total biomass. While total abundance (number of individuals) and biomass were high in autumn and winter, species richness (number of species) and diversity were high in spring. Cluster analysis, based on monthly abundance data of the 14 most frequent species, showed that the species were separated into three different groups. Group A composed of pinkgray goby, yellowfin goby, robust tonguefish (Cynoglossus robustus) and scaly hairfin anchovy (Setipinna taty), which were year-round residents, and devil flathead (Onigocia spinosa), Red dragonet (Repomucenus lunatus) and ponyfish, which were abundant in autumn, group B surmullet (Upeneus japonicus), hairtail (Trichiurus lepturus) and gaff-topsail goby (Cryptocentrus filifer), which were abundant in summer, and group C grassfish (Liparis tanakai), spotted velvefish (Erisphex pottii), chameleon goby (Tridentiger trigonocephalus) and Richardson dragonet (Repomucenus richardsonii), which were abundant in winter and spring. A seasonal homogeneity of fish assemblage indicates that overall fish assemblage in Dom Bay is largely controlled by year-round residents.

Two cases of natural human infection by Heterophyopsis continua (Heterophyidae) were identified by collection of adult worms in 1983 in Korea. And in order to know the source of infection a study on fish intermediate hosts was performed along the southwestern coastal areas. The cases were 21 and 50 year old males residing in southern coastal areas. They had the clinical complaints of non-specific gastrointestinal symptoms such as epigastric pain and one of them also complained the discharge of tapeworm segments. Praziquantel in single dose of 10~15mg/kg was given followed by purgation with magnesium salt and 2 and 46 specimens of H. continua were collected from the diarrheal stools. They said to have eaten raw ilesh of several kinds of brackish water fishes. The results of fish examination for metacercarial infection were as follows: I. Seventeen (663.0%) out of 27 perches (Lateolabrax japonicus) and 10 (29.4%) out of 34 gobies (Acantkogobius flavimanus) harboured the metacercariae but none of 42 mullets (Mugil cepkalus) were found to harbour them. 2. The average metacercarial density in perches was 55.1 and 18.7 per fish respectively. And the majority of the metacercariae were collected from the muscle of body portions in these fishes. 3. After the metaeercariae were experimentally fed to two rats and one young dog. two adult worms were recovered from the dog while none from the rats. These worms were also identified as H. continua. From the results it was concluded that the brackish water flshes which the human cases said to have eaten were the source of infection.

To assess effects of contaminants on fish in Nakdong river, feral yellowfin goby Acanthogobius flavimanus were caugt in two different sites and its hepatic monooxygenase enzyme, including cytochrome P450 (CYP), NADPH-cytochrome P450 reductase (P450R), NADH-cytochrome b5 reductase (b5R), ethoxyresorufin deethylase (EROD), glutathione S-transferase (GST) were quantitatively determined. Gonadosomatic index (GSI), hepatosomatic index (HSI) and three sex steroid hormone (17$\beta$-estradiol, E2; testosterone, T; 11-ketotestosterone, 11-KT) levels of the fish were also investigated. HSI of fish from polluted site (site 1) were significantly higher than that of unpolluted site (site 2), but GSI levels were significantly lower in polluted site. No significant differences in plasma 11-KT and T levels were observed in two sites surveyed. E2 level was, however, significantly (p<0.05) higher in female fish from site 1 than site 2. In addition, hepatic EROD activity and CYP level of site 1 fish were lower than those of site 2 fish, whereas relatively high levels of P450R, b5R and GST activities were found in site 1. The results imply that yellowfin goby, especially female fish in Nakdong river estuary are affected from contaminants disrupting sex steroid hormone system.

Fish larvae were collected from Changson channel, Namhae over the period from June 1982 to May 1983. A total of 44 species (33 families and 41 genera) were identified and described with morphological feature. The larvae of Cyclopsis tentacularis is newly reported in the Korean waters. Abundance of the species in numbers was as follows : Engraulis japonica $86.56\%$, Acanthogobius flavimanus $5.91\%$, Enedrias sp. $1.71\%$, Sebastes inermis $1.18\%$, Leucopsarion petersi $0.78\%$, Hexagrammos otakii $0.68\%$. According to variation of seasonal abundance the larvae were grouped into three seasonal groups as follows : Spring type: Engraulis japonica, Astroconger sp., Enedrias sp., Leucopsarion petersi, Sebastes inermis, Hexagrammos otakii Summer type : Engraulis japonica, Leiognathus nuchalis, Acanthogobius flavimanus, Omobranchus elegans, Syngnathus schlegeri. Winter type: Enedrias sp.

This study identified the relationship between academic stress and hopelessness among female high school students. The self-administered questionnaires were given to 334 female high school students located in D-city during the period from August 20, 2018 to September 20, 2018. As a result, the distribution of the level of hopelessness among those surveyed was 61.6% for the normal range group, 23.1% for the mild range group, 12.9% for the moderate range group, and 2.4% for the severe range group. The level of hopelessness, according to the academic stress of the study subjects, was significantly higher in the higher academic stress group than that in the lower academic stress group (p=0.000). Hopelessness also showed significant positive correlation with academic stress (r=0.371, p<0.01). The results of the logistic regression analysis showed that the risk ratio of hopelessness was significantly increased 9.27 times in the higher academic stress group when compared to that in the lower academic stress group. According to the multiple regression analysis, the significant variables affecting hopelessness were satisfaction with school life, conversation with parents, eating regularly, stress due to tests, stress due to studies and stress about career paths. Given the above results, the hopelessness of female high school students is significantly related to academic stress. Therefore, it is necessary to develop and implement programs that can properly control academic stress factors.
