  • As part of researching the feeding habit of Liobagrus somjinensis, the study of its stomach contents and benthic aquatic macroinvertebrates fauna at the waters the fish was collected were carried out monthly from January to December 2010 in Yo stream, Somjin River Sikjeong-dong, Namwon-si, Jeollabuk-do, Korea. In the survey of the stomach contents, the prey organisms are all aquatic insects consisting of 5 orders, 14 classes and 16 species. They fed mainly on Trichoptera and Ephemeroptera including dominant insects such as Hydropsyche kozhantschikovi (79.1%), Chironomidae spp. (48.7%), Baetiella tuberculata (34.2%) at the occurrence rate. Based the result, L. somjinensis appeared to be an aquatic insect feeder that consumes only benthic aquatic insects. The feeding rate of L. somjinensis was the highest in November, whereas it was the lowest in December to next February when they did not feed in the winter season. A survey of the benthic aquatic macroinvertebrates fauna was accompanied for prey preference at the waters. They have 7 orders, 20 classes and 27 species, and among them, two species, Hydropsyche kozhantschikovi (39.0%) and Epeorus pellucidus (18.1%), were aquatic dominant insects. Among 7 orders interestingly, Odonata and Megaloptera, known as having a larger size than other aquatic insects, were not found at the stomach contents. As a result, Liobagrus somjinensis most prefer Hydropsyche kozhantscikovi which is the most dominant species with relatively a smaller size at the waters the study was performed.

  • The strains selected in the previous paper were identified according to the manual of Aspergilli by Thom and Raper, and the preparation of the crude enzymes with the strains were investigated. The fermented fodders were made with wheat bran and chaffs containing 20% wheat bran by the strains, and the feeding experiments concerned was conducted. The results obtained are as follows: 1. The selected strains were identified as below; MC-9 was a similar strain of Aspergillus niger van Tieghem, MC-10 was a similar strain of Aspergillus flavus Link, MC-53 was a similar strain of Aspergillus penicilloides Spegazzini and MC-61 was a similar strain of Aspergillus niger mut Schiemanni n. comb. 2. Percentages of crude enzymes obtained from the dried matters of the wheat bran cultures were MC-9: 2.9%, MC-10: 3.9%, MC-53: 6.4% and MC-61:2.6%. And the cellulase activity of MC-9 was the most active among the crude enzymes as the same as the filtrates of wheat bran cultures. 3. As the results of the feeding experiments, changes of body weights showed no trends to be significant as compared with the control group, and the groups of MC-9 and MC-61 showed the increasing significance with P<0.05 in egg-laying rate.

  • In this paper, bandwidth improvement of a series-fed two dipole array(STDA) antenna applicable for mobile communication base station antennas is studied. The proposed STDA antenna consists of two strip dipole antennas with different lengths which are connected directly trough a coplanar stripline(CPS). By adjusting the spacing between the two dipoles and the length of the second dipole, the bandwidth of the STDA can be enhanced. In addition, an integrated balun composed of a short-circuited microstrip line and a slot line is utilized to minimize the area required for a feeding part, and a broadband impedance matching is obtained by adjusting the feeding point. Based on the proposed antenna structure, an STDA antenna covering the frequency band ranging from 1.75 GHz to 2.7 GHz, which includes almost all the existing mobile communication frequency bands, with more than 5 dBi gain is designed and fabricated on an FR4 substrate with dielectric constant of 4.4 and thickness of 1.6mm, and experimentally tested. The fabricated antenna shows impedance bandwidth of 49%(1.7-2.8 GHz) for VSWR<2, a gain higher than 5.5 dBi, and a front-back ratio better than 12 dB.

  • This essay places the South Korean film Thirst (2009) within Park Chan-wook's oeuvre as a filmmaker notorious for graphic depictions of violence and revenge. Park's use of dark humour in his films, which is emphasized in Thirst perhaps more than ever, allows for a more self-aware depiction of violence, where both the viewer and the protagonist are awakened to the futility of revenge. This ultimately paints his characters as fascinatingly crazy - simultaneously heroes, villains, and victims. Film theorist Wes D. Gehring's three themes of dark humour ('man as beast,' 'the absurdity of the world,' and 'the omnipresence of death') become most obvious in Park's most recent film, which pays closer attention to character development through narrative detail. Rather than portraying the characters as sentimental, dark humour depicts their misfortunes in an alternative way, allowing for consideration of such taboo subjects as religion, adultery, and death/suicide. These issues are further tackled through Thirst's portrayal of its vampire protagonist, which ultimately de-mystifies the traditional vampire figure. While this character has more often been associated with romance, exoticism and the mystical powers of the supernatural, Thirst takes relatively little from the demons of Nosferatu (Murnau, 1922) and various other Dracula adaptations, nor the romantic figures of Interview with the Vampire (Jordan, 1994), and Twilight (Hardwicke, 2008). Instead, it is part of a much smaller group of contemporary vampire films, which are rather informed by a postmodern reconfiguration of the monster. Thus, this paper examines Thirst as an important contribution to the global and hybrid nature of those films in which postmodern vampires are sympathetic and de-mystified, exhibiting symptoms stemming from a natural illness or misfortune. Park's undertaking of a vampire film allows for a complex balance between narrative and visuals through his focus on the Western implications of this myth within Korean cinema. This combination of international references and traditional Korean culture marks it as highly conscious of New Korean Cinema's focus on globalization. With Thirst, Park successfully unites familiar images of the vampire hunting and feeding, with more stylistically distinct, grotesque images of violence and revenge. In this sense, dark humour highlights the less charming aspects of the vampire struggling to survive, most effective in scenes depicting the protagonist feeding from his friend's IV in the hospital, and sitting in the sunlight, slowly turning to ash, in the final minutes of the film. The international appeal of Park's style, combining conventions of the horror/thriller genre with his own mixture of dark humour and non-linear narrative, is epitomized in Thirst, which underscores South Korea's growing global interest with its overt international framework. Furthermore, he portrayal of the vampire as a sympathetic figure allows for a shift away from the conventional focus on myth and the exotic, toward a renewed construction of the vampire in terms of its contribution to generic hybridization and cultural adaptation.

  • Nematode-trapping fungi develop trap and consume nematodes are an important part of the subsoil ecosystem and they share a special predator-prey relationship. Four nematode-trapping species, there with adhesive network, Arthrobotrys oligospora, A. sinensis, A. thaumasia and one with constricting ring, Drechslerella brochopaga were collected from soils in Korea and tested their predacity against 12 different nematode species. They were three feeding groups, plant-parasitic (Meloidogyne incognita and Pratylenchus penetrans), fungivorous (Aphelenchus avenae), bacteriovorous (Betlerius sp. and Diplogasteritus sp. in diplogasterid, Panagrolaimus labiatus, P. multidentatus in panagrolaimid, Mesorhabditis irregularis, Pelodera strongyloides and Rhabditis sp., in rhabditid, and Acrobeloides sp. in cephalobid). Results showed that nematode-trapping fungi successfully captured most of nematodes in Petri dish in the group of plant-parasitic nematodes and rhabditids, moderately and variably in other nematodes in 15 days. But it didn't captured A. avenae and Acrobeloides sp. both belongs to c-p group 2. Numbers of Acrobeloides sp. and A. avenae even increased during the test period. The results of this study indicated that nematode-trapping fungi may have specificity among nematode species.

  • Introduction : Oral motor function is basic function of sensory exploration, feeding, and communication, that develops from the fetal stage to childhood. Problems with oral motor function result in difficulty within handling food in the oral cavity, decreased swallowing and feeding skills, difficulty with communication, and problems with oral hygiene. To treat these symptoms, oral motor therapy is provided for normalizing sensory adaptation in the oral cavity, and increasing postural control, oral movement and oral motor function. Discussion : The oral motor facilitation technique (OMFT) was developed for increasing general and integrated oral motor function based on the following: 1) understanding orofacial muscular physiology; 2) a comprehensive approach to sensory·adaptation·behavior·cognition; 3) sensorimotor stimulation by a manual approach; 4) motor control and motor learning theory. The OMFT is a new evidence-based treatment protocol, for children and adults with neuromuscular and oral motor problems. Conclusion : The goal of this article is to provide a theoretical background for OMFT development and the basic concept for the clinical application of OMFT. We hope that this article will help oral motor therapy experts to provide effective therapy in a more professional way.

  • The parents have much expectation upon the pregnancy and child birth, and in most cases, they expect the healthy parturient child. However, we can be placed on the high-risk conditions which have the physical, social and immature infant, due to the unexpected results, among the new-born. Accordingly, these high-risk newborn and premature infants will be mostly in NICU, which the concentrated medical treatment can be given, upon their conditions. After their birth and during these periods, they will be divided from the parents, and the nurse will accomplish the bringing-up activities which they can take care of the infant, expected by the parents after their birth. The hospitalization of high-risk newborn including these premature infants is the shocking experience to the parents of family, and thus they can feel the fear and uneasiness, and these reactions of parents are troubled in the behavior at the usual days, and cause the disorder and spiritless status, and these results break the supporting ability of parents, and cause the obstruction. Also, the unavoidable division between the parents and the children as like hospitalization of children can make the parents to feel the alienation emotionally, and this causes the results which the pride on the bringing-up ability of baby gets to be lost. These problems can cause the difficulties on the bonding or the parenting in the further days, and can be related to the neglect and abuse of children. Also, it is gradually increased to study and report which the emotional division by the physical division between the mother and the baby obstructs the normal affection course between the parent and the infant. The stress caused by the birth and the hospitalization of high-risk newborn, as like this, is important in the points which it can uncertainly affect the potential energy for the relationship of parent-child who are finally healthy. Accordingly, the significance and purpose of this study are to understand the contents and degree of stress which the parents of high-risk newborn including the immature child can be experienced from the hospitalization of ICU for their new borns, and thus to offer the basic program to the nursing intervention program for these. The subject of this study is the mother of newborn in NICU of 10 General Hospitals located at the 3one of Pusan, Korea from September 1997 to October 1997, and thus makes the subject of 95 person of parents who agreed to take part in the study and it is descriptive study related to the stress of mother having the newborn in NICU. The method is based on the preceding study related to the stress of mother having the experience of child hospitalization and chronic disease child, and then acquires the advice of specialists group as like 5 nursing professors, and then is amended and supplemented. Total number of questions is 43 items and consists of 5 factors as like medical treatment &nursing procedures, disease status & prognosis, role of parents, communication & inter-personal relationships, hospital environment, and is 5 point Likert Scale. The reliability of this study method is very highly shown to be Cronbach α=0.95. The collected data is analysed as Average, Frequency, Standard Deviation, T-test, ANOVA, Pearson Correlation Coefficient, Duncan multifulrange test by use of SPSS /PC (V7.5). The results of this study is summarized as under. 1. Every characteristics of subject is which the party of mother is 28.70age(±7.48) in the average ages, 51% in the high-school graduate, 38.5% in the christianity, total monthly income is 212.55 thousand won(±1.971), 74.5% in the housewife, 72.9% in the parents and children together living and the number of children to be 1.48person(± 0.6) in average, the recognition on the prognosis of baby is 74.0% in 'Don't know', the relationship with the husband after the hospitalization of babyis 37.3% in 'More Intimate', the relationship with the family of husband to be 48% in 'No-change', and the degree which is consulted with the husband about the baby is 55% in 'very frequently' and the visiting number per week is 4.59(±1.63) in average and the accompanying person in the time of visiting is which the number of husband is 56.3% and thus is the highest. The characteristics of baby is which the age is 21.88days(±16.47) after the birth in average, the sex to be 50 person in the female 52.1% and the order of birth to be 54.2% in the first chid, and the weight in the birth to be 2770gm(±610) and the height in the birth to be 46.26cm(±7.62) in aver age. The medical diagnosis is 37.5% in the premature infant, the career of hospitalization is 96.9% in 'None', and the operation plan is 90.6% in 'None' and the execution of operation is 88% in 'None' and the nursing of incubator is 55.2% in 'Yes', and the method of feeding is 50.5% in 'Oral' and the contents of feeding is 46.9% in the 'Milk'. 2. The total stress degree of subject is almost highly shown to be as 3.36(±0.86). If it is compared upon each cause, 'stress on disease status & prognosis' is highest 3.79(±1.28), and it is in the order of 'stress on medical treatment & nursing procedures' 3.70(±0.93), 'stress on hospital environment' 3.14(±0.86), 'stress on role of parents' 3.18(±0.92) and 'stress on communication & inter personal relationship' 2.62(± 0.77) 3. As the results of checking the notworthiness of stress degree upon each variable of subject, the variable showing the noted difference was the birth weight(γ=-0.16, P=0.04), birth height(γ=-0.23, P=0.03), nursing in the incubator(F=8.93, P=0.04), feed method(F=2.94, P=0.04). That is to say, it is shown which the smaller the birth weight is, the higher the stress degree of mother is noteworthily. Also, the smaller the birth height baby is, the higher the stress of mother is. In the incubator, it os shown which the mother whose baby is nursing in the incubator is higher in the stress degree than other mothers. Upon the feeding method of baby, that is to say, TPNis the highest, and it is shown in the order of NPO, Tube feeding, and P.O. feeding. When we review the above-mentioned results, as the status is serious, it is thought which we include the supporting nursing for coping with the stress of parents in the setting-up od nursing plan for the baby in the NICU.

  • Age composition and reproductive period o the shad, Konosirus punctatus, in Cheonsu Bay were determined though analysis of sizi, ane and maturity of fish. Sampses were collected with trap in the bay mouth from May, 1981 to December, 1982. Shads start entering the bay for feeding and spawning in spring when water temperature exceeds 8$^{\circ}C$. They stay in inner part of the bay in summer nad move out to sea in autumn before water trmperature decreasea to 8$^{\circ}C$. Fish grows very rapidly during first summer after birth. Mean lengthes of 1-4 year old fishes were 12.2cm, 15.8cm, 17.6cm and 20.9cm, respectively. The largest and oldrst fish pbserved was 22.0cm long with age 4. Shads of Cheonsu Bay reach maturity at 2 years old at the size greater then 14cm. Data on size and age at first maturityindicate thzt maturity of shad depends on size and not on age. Spawning occurs from late April to late May when water temperature is between 8$^{\circ}C$ and 15$^{\circ}C$.

  • In a $2{\times}2$ factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietary calcium (Ca) to phosphorus (P) ratio in phytase-supplemented feeds with a marginal P concentration has a positive effect on bone mineralization. The four experimental diets, which contained 0.4% P and were supplemented with 1,000 FTU phytase/kg, contained either 5 g BA/kg or no BA and either 0.77% Ca or 0.57% Ca. The 68 four-week-old Large White pigs were fed the experimental diets ad libitum for six weeks and were then slaughtered. Benzoic acid increased feed intake (p = 0.009) and growth rate (p = 0.051), but did not influence the feed conversion ratio (p>0.10). Benzoic acid decreased the pH of the urine (p = 0.031), but did not affect breaking strength and mineralization of the tibia (p>0.10). The wide Ca:P ratio decreased feed intake (p = 0.034) and growth rate (p = 0.007) and impaired feed the conversion ratio (p = 0.027), but increased the mineral concentration in the fat-free DM of the tibia (p = 0.013) without influencing its breaking strength (p>0.10). The observed positive effect of the wide Ca:P ratio on bone mineralization may be attributed, at least in part, to the impaired feed conversion ratio, i.e. to the higher feed intake and consequently to the higher mineral intake per kg BW gain. The negative impact on animal performance of the wide dietary Ca:P ratio outweighs its potentially positive effect on bone mineralization, precluding its implementation under practical feeding conditions.

  • The present study was designed to assess whether dietary inorganic and organic selenium (Se) could affect antioxidant enzymes, including superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST), and the level of malondialdehyde (MDA), a marker of lipid peroxidation, in the intestine, serum, liver, and gastrocnemius muscle of Korean native goats. A total of eighteen Korean native goats was allotted into three dietary groups, consisting of basal diet (CON), or basal diet with either 0.25 ppm inorganic (IOSEL) or 0.25 ppm organic Se (ORSEL), and fed the corresponding diets for 5 wks. Growth performance, including body weight and total gain, and blood biochemical profiles, including GSH-Px, were not significantly different between the three dietary groups. Also, the specific activities of SOD, GSH-Px, and GST, and the level of MDA in the intestinal mucosa and liver from goats were not substantially affected by either inorganic Se or organic Se. However, goats fed the diet containing organic Se showed a significant increase in GSH-Px and GST activities in the gastrocnemius muscle compared with those fed the basal diet. In conclusion, increased muscle GSH-Px and GST activities suggest that dietary organic Se may affect, at least in part, the antioxidant defense system in muscle of Korean native goats under the conditions of our feeding regimen.
