Travel by airplane using airport in globalized modern society is familiar to our life but such airport can be a target of terrorists who would threaten our safety. However, aviation terrorism which is represented by 9.11 terror gives horror beyond our imagination to modern people. Since the first airplane hijacking in Peru in 1931 happened, security organization in each nation has taken various prevention measures to block aviation terrorism. The most realistic measures to prevent aviation terrorism would be security check activity to control approach of terrorist that passengers on airplane and cargos are checked to find out dangerous article like explosive etc. But security check activity in Korea shifted to security check activity focused on private security for efficiency of airport operation differently from security check activity in advanced countries where public interests is strengthened according to risk of terror after 9.11 system. That is, since Incheon airport opened in March 2001, security check system focused on the police was changed. Now Incheon international airport Corporation instructs and supervises security check job and private security personnel are in charge of actual security check activity. But this check system has limitation in blocking terror activity by terrorists which is systematized and intelligent as time passes due to deteriorated job satisfaction of private security personnel and confusing supervising system. Accordingly, it is suggested to introduce risk management skill which is one of management strategy of private corporation for security check activity to prevent terror activity. With this skill, risk factors of aviation terror are identified and analyzed regularly, and each process such as setting of priority, activity to reduce risk, and assessment of security is carried out. And it would be necessary to do efforts, for example, to properly change level of security check according to threat of terror such as to place policeman at airport security in case threat of terror is severe. On the other hand, it is necessary to establish national police organization for good communication of security check activity in field and supervising function, which can encourage systematization and specialization of aviation security job.

This experiment was conducted to determine the economic application method of Yakto among 6 application method : amount of Yakto application $3\;plot(70\;l,\;25.5\;l,\;13,3\;l/kan;\;180cm{\times}90cm),$ and added side dressing(3 l/kan) each plot. The reduced amoumt of Yakto application(25.5 l, 13.3 l/kan) were lower the contents of inorganic nitrogen, $P_{2}O_{5},\;K,\;Ca$ and Mg, but similar pH in bed soil compared with standard Yakto application(70 l/kan). Side dressing applicated on 29 May increased the contents of inorganic nitrogen, $P_{2}O_{5},\;K,\;Ca,\;Mg$ and salt concentration in bed soil compared with non­side dressing in each Yakto application plot(70 l, 25.5 l, 13,3 l/kan). The reduced amoumt of Yakto application(25.5 l/kan) added side dressing(3 l/kan) were similar the contents of inorganic nitrogen, K, Mg and salt but lower $P_{2}O_{5}$ and Ca in bed soil compared with standard Yakto application(70 l/kan) in June. The reduced amoumt of Yakto application(25,5 l/Kan) added side dressing(3 l/kan) was similar the contents of P, K, Ca and Mg but lower N in leaves compared with standard Yakto application(70 l/kan). The reduced amoumt of Yakto application(25.5 l/kan) added side dressing(3 l/kan) was shorter stem length, and higher $5{\%}$ chlorosis of leaf tip, but similar emergence ratio, survival ratio, leaf senescence ratio, chlorophyll, stem diameter and leaf area compared with standard Yakto application(70 l/kan). These suggested that 25.5 l Yakto application added side dressing(3 l/kan) per kan might be possible economical application method of Yakto.

Background: The overexpression of transforming growth factor-beta 1 receptor II (TGF-${\beta}1$RII) and transforming growth factor-beta 1 (TGF-${\beta}1$) ligand may be involved in the formation of a bulla. In this study, we tested if serum TGF-${\beta}1$ ligand levels correlated with the expression level of TGF-${\beta}1$RII and TGF-${\beta}1$ in bullous tissues from patients with spontaneous pneumothorax. Material and Method: Bullous lung tissues and blood samples were obtained from 19 patients with spontaneous pneumothorax, 18 males and 1 female, aged 17 to 35 years old. The bullous tissues were obtained by video-assisted thoracic surgery (VATS), fixed in formalin, embedded in paraffin, and cut into $5{\sim}6{\mu}m$ thick slices. Sections were immunohistochemically stained with primary antibodies against TGF-${\beta}1$ or TGF-${\beta}1$RII, and serum levels of TGF-${\beta}1$ in patients and normal controls was measured by enzyme-linked immunosorbent assay (ELISA). Result: Of the 19 patients, 16 were TGF-${\beta}1$ positive and 10 were TGF-${\beta}1$RII positive. Among the 16 TGF-${\beta}1$ positives, 9 were also TGF-${\beta}1RII$ positive. As seen previously, strong immunohistochemical staining of TGF-${\beta}1$RII and TGF-${\beta}$ was detected in the boundary region between the bullous and normal lung tissues. Average TGF-${\beta}1$ blood levels of both TGF-${\beta}1$ and TGF-${\beta}1$RII positive patients was $38.36{\pm}16.2ng/mL$, and that of five controls was $54.06{\pm}15ng/mL$. Conclusion: These results suggest that overexpression of TGF-${\beta}1$ and TGF-${\beta}1$RII expression may be involved in the formation of bullae. TGF-${\beta}1$ blood levels in patients with primary spontaneous pneumothorax is lower than normal people, suggesting that the high level of local TGF-${\beta}1$ expression in the bullous tissue region, but not in the whole blood, may contribute more in the formation of bullae.

Fresh dairy cow manure was mixed with dried sawdust at the following moisture contents and manure: sawdust ratios: 50% and 57:43 ($\underline{M50}$), 55% and 64:36 ($\underline{M55}$), 60% and 70:30 ($\underline{M60}$), 65% and 76:24 ($\underline{M65}$), 70% and 83:17 ($\underline{M70}$) 75% and 90:10($\underline{M75}$) and 80% and 96:04($\underline{M80}$). The mixtures were fermented by a fungal mycelium of Fomitella flaxinea for 2wk at 29 C to recycle cow manure along with sawdust and fungal mycelium as a ruminant feedstuff. Chemical composition and in vitro rumen dry matter digestibilities of fermented mixtures were compared with unfermented mixture. The crude protein contents of mixtures were not changed by fermentation with fungal mycelium. Neutral detergent fiber contents of 4WK fermented mixtures (90.6, 85.3, 80.4, and 76.4% for $\underline{M50}$, $\underline{M60}$, $\underline{M70}$ and $\underline{M80}$, respectively were lower (P<0.05) than those of unfermented mixtures (91.1, 89.9, 84.3, and 79.4%). However, acid detergent fiber contents of fermented mixtures (73.8, 68.9, 65.3, and 58.0%) were higher (P<0.05) than those unfermented mixtures (70.2, 67.8, 61.7, and 56.3%). In vitro rumen dry matter digestibilities of fermented mixtures for four weeks(49.4, 36.8, 28.6, and 22.3% for $\underline{M50}$, $\underline{M60}$, $\underline{M70}$ and $\underline{M80}$) were higher than those of unfermented mixtures(34.1, 27.5, 20.6, and 15.4%) (P<0.05).

We analyzed mupirocin resistance rates among staphylococcal isolates collected from a Korean hospital in 2003 (100 isolates), 2005 (195 isolates), 2006 (151 isolates), and 2009 (112 isolates). In Staphylococcus aureus, rates of high-level mupirocin resistance (MIC, minimal inhibitory concentration ${\geq}512{\mu}g/ml$) decreased and did not appear since 2005. In contrast, low-level mupirocin resistance (MIC $8-256{\mu}g/ml$) was not detected in 2003 and 2005 but its rates later increased to 6.9% in 2009. Total resistance rates of coagulase-negative staphylococci (CNS) were significantly higher than those of S. aureus. The rates of high-level resistance of CNS increased from 16.0% in 2003 to 31.5% in 2009. The rate of low-level resistance of CNS was 8.0% in 2003 and around 11% later. In all high-level resistant isolates, the ileS-2 gene was detected. All low-level resistant isolates contained the known V588F mutation in ileS gene. Previously unknown mutations such as V458G in S. aureus and D172A, Y490H and I750V in CNS were identified additionally. One S. aureus isolate with high-level resistance was resistant to oxacillin and several topical antibiotics commonly used for the treatment of skin infection. Ten S. aureus isolates with low-level resistance were also resistant to all of these antibiotics except fusidic acid. CNS isolates with high-level (61 isolates) and low-level resistance (27 isolates) exhibited significantly higher resistance rates to these antibiotics than mupirocin-susceptible CNS isolates (167 isolates). In conclusion, prevention of the emergence of mupirocin resistance is necessary for the effective treatment of skin infection by staphylococci.

Senile Dementia is one of the dispositional mental disorder which has been known to the world since Hippocratic age. It has become a wide-spread social problem all over the world because of chronic disease processes and the demands of dependent care for several years as well as improbability of treatment of it at the causal level. Essentially, life styles of the older generation differ from those of the younger generation. While the fomer is used to the patriarchal system and the spirit of filial piet and respect, the latter is pragmatized and individualized under the effects of the Western material civilization. These differences between the two generations cause conflict between family members. In particular, the pain and conflict of care-givers who take care of a totally dependent dementia patient not only is inciting to the collapse of the family union, but is expanding into a serious social problem. According to this practical difficulty, this study has tried to compare dementia care-givers' experiences inter-culturally and to help set up more proper nursing interventions, describing and explaining them through ethnographies by participant observation and in-depth interviews that enable seeing them in a more close, honest and certain way. It also tries to provide a theoetical model of nusing care for dementia patients which is proper to Korean culture. This study is composed of 12 participants (4 males, 8 females) whose ages range from 37-71 years. The relations of patients are 5 spouses(3 husbands, 2 wives), 4 daughters-in-law, 2 daughters, and 1 son-in-law. The following are the care-givers' meaning of experiences that results of the study shows. The first is "psychological conflict". It contains the minds of getting angry, reproaching, being driven to dispair, blaming oneself, giving up lives, and being afraid, hopeless, and resigned. The second is "physical, social and psychological pressure" . At this stage, care-givers are shown to be under stress of both body and soul for the lack of freedom and tiredness. They also feel constraint because they hardly cope with the care and live through others' eyes. The third is "isolation". It makes the relationship of patient care-giver to be estranged, without understanding each other. They, also, experience indifference such as being upset and left alone. The forth is "acceptance" They gradually have compassion, bear up and then adapt themselves to the circumstances they are in. The fifth is "love". Now they learn to reward the other with love. It is also shown that this stage contains the process of winning others' recognition. The final is "hope". In this stage they really want situations to go smoothly and hope everything will be O.K. These consequences enable us to summarize the principles of cue experience such as, in the early stage, negative response such as physical·psychological confusion, pain and conflict are primary. Then the stage of acceptance emerges. It is an initial positive response phase when care-givers may admit their situations. As time passes by a positive response stage emerges. At last they have love and hope. Three stages we noted above : however, there are never consistent situations. Rather it gradually comes into the stage of acceptance, repeating continuous conflict, pressure and isolation. If any interest and understanding of families or the support of surrounding society lack, it will again be converted to negative responses sooner or later. Otherwise, positive responses like hope and love can be encouraged if the family and the surroundings give active aids and understanding. After all, the principles of dementia care experiences neither stay at any stage, nor develop from negative stages to positive stages steadily. They are cycling systems in which negative responses and positive responses are constantly being converted. I would like to suggest the following based on the above conclusions : First, the systematic and planned education of dementia should be performed in order to enhance public relations. Second, a special medical treatment center which deals with dementia, under government's charge, should be managed. Third, the various studies approaching dementia care experiences result in the development of more reasonable and useful nursing guidelines.

Reproductive cycle with the gonadal development of Ruditapes philippinarum can be classified into five successive stages by histological observations: early active stage (January to March), late active stage (February to May), ripe stage (April to August), partially spawned stage (May to October), and spent/inactive stage (August to February). Changes in total protein contents in the adductor muscle tissues reached the maximum in the early and late active stages (February) and appeared the minimum in the ripe and partially spawned stages (May), while changes in their contents in the visceral mass tissues reached the maximum in the ripe and partially spawned stages (June) and gradually decreased in the partially spawned stage (June to October). On the whole, changes in total protein contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.292, p < 0.05). Changes in total lipid contents in the adductor muscle tissues reached the maximum in the inactive and early active stages (January) and sharply decreased in the early and late active stages (February), while their contents in the visceral mass tissues reached the maximum in the ripe and partially spawned stages (April) and gradually decreased in the partially spawned stage (to October). On the whole, changes in total lipid contents showed a negative correlationship between the adductor muscle and visceral mass tissues (r = -0.699, p<0.05). Changes in glycogen contents in the adductor muscle tissues reached the maximum in the late active and ripe stages (April) and rapidly decreased in the partially spawned stage (May to October), while their contents in the visceral mass tissues reached the maximum in the early and late active stages (February) and rapidly decreased in the late active stage (March). Thereafter, their levels gradually increased in the ripe and partially spawned stages (April to July). On the whole, changes in glycogen contents appeared no correlationship between the adductor muscle and visceral mass tissues (r = 0.062, p > 0.05). These results indicate that the adductor muscle and visceral mass tissues are an important energy storage and nutrient supply organ in the Manila clams, and the nutrient contents of the adductor muscle and visceral muscle tissues change in response to gonadal energy needs.

Ultrastructure of germ cells, the cyst epithelial cells and interstitial cells during spermatogenesis of the stone flounder, Kareius bicoloratus (Pleuronectidae) sampled on the west coast of Korea were investigated by electron microscopic observations. In the primary spermatocyte, the synaptonemal complexes appear in the zygotene stage of the prophase during maturation division. In the growing testis, especially, the interstitial cells (Leydig cells) appear near the primary, secondary spermatocytes and spermatids. Well-developed interstitial cells (steroid hormone secreting cells) which are located in the interlobular space in growing testis have three morphological characteristics of a vesicular nucleus, mitochondria with tubular cristae and smooth endoplasmic reticulum. During spermatogenesis, the primary and secondary spermatocytes attach to the cyst epithelial cell (Sertoli cell) having an elongated ovoid or triangular nucleus and several mitochondria in the cytoplasm. In the growing testis, lipid droplets, the mitochondrial rosettes and glycogen particles appear in the cytoplasm of the cyst epithelial cells near the secondary spermatocytes and spermatids. Particularly, the mitochondria, endoplasmic reticulum, little lipid droplets and the large amount of glycogen particles are present in the cytoplasm of the cyst epithelial cell in the late growing testis. In the late stage of spermiogenesis, the proximal centriole is joined to the nuclear envelope, the distal centriole forms the basal body of the flagellum and gives rise to the axial filament of the flagellum. No acrosome of the sperm is formed as seen in other teleost fish. The head of the spermatozoon is approximately $3{\mu}m$ in length and its tail is about $30{\mu}m$ in length. The axoneme of the tail flagellum of the spermatozoon consists of nine outer doublet microtubules at the periphery and two centrial singlet microtubules at the center. The spermatozoon of this species has two axonemal lateral fins. Especially, the cyst epithelial cells which located near groups of gametes in the various stages, show three functions: nutrition, phagocytosis and steroidogenesis. Especially, the nuclei of cyst epithelial cells in the recovery stage of the testicular developmental stages appear to be irregular in shape after spermiation. Of three functions of the cyst epithelial cell, several characteristics of phagocytosis are showed in the cytoplasm of the cyst epithelial cells in the recovery stage of the testicular developmental stages. At this stage, therefore, it is assumed that the cyst epithelial cells are involved in degeneration and resorption of undischarged germ cells after spermiation.
