War films are a general term for films that have battlefields as their main background. Although war films as a genre directly deal with combat situations, they also deal with characters or subjects related to war. War films promote patriotism and nationalism, but they also argue against war by highlighting the disastrous war. This study is based on the color theory that the meaning of film color is temporarily and infinitely generated according to the cultural differences, with Eisenstein's creative theory on film color and pathos. I wanted to clarify the pathos effect and the meaning of color green expressed in the Korean war films. In war films, colors are visualized in art forms such as symbols, similes and metaphors. In war films, color green symbolizes life. On the battlefield, the green of nature stands against the catastrophic situation. The green of ecology, which insists on the flow of life, evokes fear in ecological crises such as war, disaster and climate change. The dark green caused by a catastrophe like war warns of the destruction of life. The connotation of color is temporarily and infinitely expands according to the cultural differences. The dark green, which visualizes the battlefield of destruction, is a form and element of pathos that indicates changes in emotions such as sadness, pity, grief and despair. Pathos as an emotional appeal is a leap from the quality to the quality of the means of expression and refers to the departure from Dasein. The green color that dominates the visuals of war films is a symbol of life and functions as a pathos that makes emotional changes take a new leap. A qualitative leap through pathos means all changes that become new.

Green infrastructure planning represents landscape planning measures to reduce particulate matter. This study aimed to derive factors that may be used in planning green infrastructure for particulate matter reduction using text mining techniques. A range of analyses were carried out by focusing on keywords such as 'particulate matter reduction plan' and 'green infrastructure planning elements'. The analyses included Term Frequency-Inverse Document Frequency (TF-IDF) analysis, centrality analysis, related word analysis, and topic modeling analysis. These analyses were carried out via text mining by collecting information on previous related research, policy reports, and laws. Initially, TF-IDF analysis results were used to classify major keywords relating to particulate matter and green infrastructure into three groups: (1) environmental issues (e.g., particulate matter, environment, carbon, and atmosphere), target spaces (e.g., urban, park, and local green space), and application methods (e.g., analysis, planning, evaluation, development, ecological aspect, policy management, technology, and resilience). Second, the centrality analysis results were found to be similar to those of TF-IDF; it was confirmed that the central connectors to the major keywords were 'Green New Deal' and 'Vacant land'. The results from the analysis of related words verified that planning green infrastructure for particulate matter reduction required planning forests and ventilation corridors. Additionally, moisture must be considered for microclimate control. It was also confirmed that utilizing vacant space, establishing mixed forests, introducing particulate matter reduction technology, and understanding the system may be important for the effective planning of green infrastructure. Topic analysis was used to classify the planning elements of green infrastructure based on ecological, technological, and social functions. The planning elements of ecological function were classified into morphological (e.g., urban forest, green space, wall greening) and functional aspects (e.g., climate control, carbon storage and absorption, provision of habitats, and biodiversity for wildlife). The planning elements of technical function were classified into various themes, including the disaster prevention functions of green infrastructure, buffer effects, stormwater management, water purification, and energy reduction. The planning elements of the social function were classified into themes such as community function, improving the health of users, and scenery improvement. These results suggest that green infrastructure planning for particulate matter reduction requires approaches related to key concepts, such as resilience and sustainability. In particular, there is a need to apply green infrastructure planning elements in order to reduce exposure to particulate matter.

Increasing discovery cases of underground storage facilities made of earth, wood, or stone are being reported from the recent excavation survey of the Baekje relics. Accordingly, the purpose of this study is to examine the structure and function of the underground storage facilities of Baekje following a classification made by the type and building method as follows: plask shape, wooden box shape, and stone box shape. The plask shape storage is the most representative underground storage of Baekje that has been found in numerous relics more than 600 sets around Hangang(Han River) and Geumgang(Geum River) from the Hansung period to Sabi period in Baekje Dynasty. It is a historical artefact as a part of the unique storage culture of Baekje around Hangang and Geumgang from the 3rd to 7th Century. Considering its structure and the example of Chinese one, it might had been used for a long-term storage of grains and various other items including earth wares. The storage facility in wooden box shape and stone box shape are found mostly in the relics Of Sabi period. Thus it might had taken some functions of the storage in traditional pouch shape which had decreased after the 6th Century. In particular, the wooden box shape and stone box shape storage required enormous labor force to build owing to their structure and building method. Thus, they were considered to had been used for official purposes in province fortress and citadel artefact. The wooden box shape storage facility is classified into flat rectangular type and square type based on the structure, and into Gagu type(架構式) and Juheol type(柱穴式) based on the building method. It might had been decided according to the geography and geological feature of the place where the storage was to be built. Considering the examples of Gwanbuk-ri relics and Weolpyong-dong relics, the wooden box shape storage facility might had been used for various items depending on the needs, including foods such as fruits and essential provisions at the military base. Considering the long-term food storage, the examples in Japan, and the functional characteristics of the underground storage facility, there is a possibility that the wooden and stone box shape storage facilities had been built so as to safely store important items in case of fire. This study is only a rudimentary examination for the storage facility in Baekje. Thus further studies are to be made specifically and comprehensively on the comparison with other regions, distribution pattern, discovered relics and artefacts, and functions.

Background: To evaluate the risk factor and long-term result of arterial switch operation , a retrospective study was done. Material and Method: A retrospective analysis was done to evaluate the early and long-term results on 58 patients who underwent an arterial switch operation(ASO) for transposition of the great arteries(TGA) with intact ventricular septum, between January 1988 and December 1996. Beforesurgery, 36 patients(62.1%) underwent balloon atrial septostomy, 32 patients(51.7%) received PGE1 infusion, and preparatory banding of pulmonary artery was performed on 6 patients(mean LV/RV pressure ratio 0.53$\pm$0.11). Result: The age at operation ranged from 1 to 137 days(mean 24$\pm$26 days) and the weights ranged from 1.8 to 6.8 kg (mean 3.5$\pm$0.8 kg). There were 14 early deaths(24.1%), but of the last 24 patients operated on since 1994, there were only 2 early deaths(8.3%). In the risk factor analysis, the date of operation was the only risk factor for early death(p-value < 0.01). Eight of the 14 early deaths were due to acute myocardial failure(mainly inadequate coronary blood flow). The length of follow-up ranged from 2 months to 8 years, average of 36$\pm$27 months. The follow-up included sequential noninvasive evaluations and 21 catheterizations and angiographic studies performed 5 to 32 months postoperatively with particular attention to the great vessel and coronary anastomosis, ventricular function, valvular competence, and cardiac rhythm. There were 5 late deaths(11.4%), one of thesedeaths was related to the late coronary problems, two to aspiration, one to uncontrolled chronic mediastinitis, and one to progressive aortic insufficiency and heart failure. The most frequent postoperative hemodynamic abnormality was supravalvular stenosis and the degree of pulmonary or aortic obstruction had slowly progressed in some cases, however there were no children who had to undergo a reoperation for supravalvular pulmonary or aortic stenosis. Aortic regurgitation was identified in 9 patients, which was mild in 7 and moderate in 2 and had progressed in some cases. Two patients who had an unremarkable perioperative course were identified as having coronary artery obstructions. The other late survivors were in good condition, were in sinus rhythm, and had normal LV functions. Actuarial survival rate at 8 years was 68.8%. Conclusion: We concluded that anatomic correction will be established as the optimal approach to the TGA with intact ventricular septum, though further long-term evaluations are needed.

Objectives: Members of the immortalization-upregulated protein (IMUP) family are nuclear proteins implicated in SV40-mediated immortalization and cellular proliferation, but the mechanisms by which their expression is regulated are still unknown in placenta. To investigate to expression and functions of IMUPs in placenta, we conducted to compare IMUPs expression in normal and preeclamptic placenta tissues and analyzed the function of IMUP-2 in HTR-8/SVneo trophoblast cells after IMUP-2 gene transfection. Methods: The expression of IMUPs was analyzed in placental tissues from the following groups of patients (none underwent labor): 1) term normal placenta (n=15); 2) term with preeclamptic placeneta (n=15); and 3) pre-term with preeclamptic placenta (n=11) using semi-quantitative RT-PCR, RNA in situ hybiridization, immunohistochemistry, and Western blot. In order to evaluate the function of IMUP-2 in HTR-8/SVneo trophoblast cells, IMUP-2 plasmids were transfected into HTR-8/SVneo trophoblast cells for 24 hours. Results: We observed that IMUPs are mainly expressed in the syncytiotrophoblasts and syncytial knot of placental villi. The expression of IMUP-1 was not differences between normal and preeclamptic placenta tissues. However, IMUP-2 expression was significantly higher in preterm preeclamptic placenta tissues than in normal placenta tissues without labor (p<0.001). Furthermore, we confirmed overexpression of IMUP-2 induced apoptosis in HTR-8/SVneo trophoblast cells through up-regulation of pro-apoptotic proteins. Conclusions: These results suggest that the expression of IMUP-2 is involved in placental development as well as increased IMUP-2 expression is associated with preeclampsia through the inducing of trophoblast apoptosis.

Moisturizers are the most prescribed products in dermatology. Treatment with moisturizers aims to maintain skin integrity and overall well-being by providing a healthy appearance. Moisturizers perform very important functions in baby care; however, there are few studies on the effects of moisturizers on the skin of infants. To investigate the effects of moisturizers on the skin of healthy full-term infants and toddlers, thirty-one healthy, full-term, 6- to 36-month-old infants and toddlers without any dermatologic conditions received moisturizer applied to the whole body except the eyes and diaper area after bathing twice daily for 4 weeks. Clinical assessments were conducted before treatment, immediately after the treatment period, and 1 and 4 weeks after treatment. At all visits, skin hydration, transepidermal water loss (TEWL), skin pH, and skin roughness were measured, the skin surface was photographed, and any adverse events were recorded. After using moisturizer, skin hydration significantly increased and TEWL and roughness significantly decreased. The skin pH was modified to mildly acidic and the skin surface was visually smoother than before treatment. There were no statistical significant differences of effects of moisturizers according to age and sex, and adverse events were not observed. The results of moisturizer application on the skin were increased skin hydration, recovery of barrier function, balancing skin pH within a mildly acidic range, and increasing the smoothness of the skin surface for 4 weeks.

Purpose: To evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in elderly patients older than 70 years by analyzing cases that have been implanted for >10 years ago. Materials and Methods: The long-term follow-up results were evaluated in 39 patients (46 cases) who underwent medial UKA from March 2002 to February 2004. The mean age of the patients at the time of surgery was 74.0 years, and the preoperative diagnosis was degenerative arthritis of the knee in all cases. Results: Of the 46 cases, reoperation occurred due to the complications in four cases. In 22 cases without 14 cases of death and six cases of follow-up loss, follow-up more than 10 years was possible. The mean Knee Society knee and function scores improved significantly from 53.0 and 52.5 points pre-operatively to 89.4 and 80.9 points at the last follow-up, respectively (p<0.001). The mean range of motion of the knee recovered to 132.5°, and the mean tibiofemoral angle changed to 5.9° of valgus at the last follow-up. Complications following the UKA occurred in four cases; the most prevalent complication was mobile bearing dislocation (n=2). One case of failure occurred due to aseptic loosening and degenerative arthritis of the lateral compartment, respectively. The cumulative survival rate of the implants was 95.0% at 10 years and 85.7% at 15 years. Of the 40 cases, excluding six cases of follow-up loss, 36 cases (90.0%) could be used without reoperation until death or at the last follow-up after surgery. Conclusion: These results showed the outstanding functions of the knee and satisfactory long-term survivorship after UKA. Therefore, UKA could be a useful method for the treatment of osteoarthritis of the knee in elderly patients older than 70 years of age.

Objectives: The objective of this study is to assess cognitive functions and their relationship with sleep symptoms in young narcoleptic patients. Methods: Eighteen young narcolepsy patients and 18 normal controls (age: 17-35 years old) were recruited. All narcolepsy patients had HLA $DQB_1$ *0602 allele and cataplexy. Several important areas of cognition were assessed by a battery of neuropsychological tests consisting of 13 tests: executive functions (e.g. cognitive set shifting, inhibition, and selective attention) through Wisconsin card sorting test, Trail Making A/B, Stroop test, Ruff test, Digit Symbol, Controlled Oral Word Association and Boston Naming Test; alertness and sustained attention through paced auditory serial addition test; verbal/nonverbal short-term memory and working memory through Digit Span and Spatial Span; visuospatial memory through Rey-Osterrieth complex figure test; verbal learning and memory through California verbal learning test; and fine motor activity through grooved pegboard test. Sleep symptoms in narcolepsy patients were assessed with Epworth sleepiness scale, Ullanlinna narcolepsy scale, multiple sleep latency test, and nocturnal polysomnography. Relationship between cognitive functions and sleep symptoms in narcolepsy patients was also explored. Results: Compared with normal controls, narcolepsy patients showed poor performance in paced auditory serial addition (2.0 s and 2.4 s), digit symbol tests, and spatial span (forward)(t=3.86, p<0.01; t=-2.47, p=0.02; t=-3.95, p<0.01; t=-2.22, p=0.03, respectively). There were no significant between-group differences in other neuropsychological tests. In addition, results of neuropsychological test in narcolepsy patients were not correlated with Epworth sleepiness scale score, Ullanlinna narcolepsy scale score and sleep variables in multiple sleep latency test or nocturnal polysomnography. Conclusion: The current findings suggest that young narcolepsy patients have impaired attention. In addition, impairment of attention in narcolepsy might not be solely due to sleep symptoms such as excessive daytime sleepiness.

South Korea has entered the age of aging society since the elderly population over 65 reached 13.1% in 2015. This increase rate is the fastest in the OECD members. as a part of the precaution, the Korean government has enforced the long term care insurance from July 2008 and the increase of related nursing homes until 2015 was 220.2% which is rapid and quantitative. It was natural that quantitative expansion leads to qualitative improvement. With regard to service environment conditions, color environment draws attention as one of the most effective measures. color environment supports nursing home's spatial functions and the aged class is subject to the research as the potential customers. This study aims to understand color environment, conduct surveys for color preference and attitude toward color environment, and suggest directions for color environment plan. The ultimate goal is to improve the quality of Korean nursing home environment. It studied definition, state, color environment and space functions of nursing homes as well as the preceding researches. With 100 people over 60s in Busan and Gyeongnam area (52 male and 48 female), the survey examined attitudes for color environment and color preference by space functions in nursing home. The research method is as follows. First, as a result of the consciousness survey on color environment in elderly nursing home, it considers service (37%), medical service (20%), and location (19%) heavily in order. color environment plan is not recognized significantly. However, the need of indoor color plan in the elderly nursing homes has "agree (32%) and "strongly agree (25%), which suggests that color introduction is required to the nursing homes. Second, the indoor coloration for the elderly nursing homes has various color preferences. The color preference order for bedroom was R, P, and G but this order changes in nursing space (program room) to G, R, and Y. The communal space such as lobby prefers R, G and Y in order. R color was preferred in general.

Objectives: This study investigated the anti-osteoarthritic effects of Kyejiinsam-tang (hereinafter referred to KIT) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods: Anti-oxidative effects of KIT were measured by scavenging activities of DPPH, reactive oxygen species (ROS) and nitric oxide (NO). Scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cells were also measured for inhibitory effects against the production of inflammatory mediators (tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, interleukin-6). Osteoarthritis was induced in rats by injecting MIA in the knee joint. Rats were divided into a total of 4 groups (n=6). The normal group were not treated at all without inducing osteoarthritis whereas the control group were induced for osteoarthritis by MIA and oral medicated physiological saline per day. The positive comparison group was injected with MIA and after 7 days, 2 mg/kg of Indomethacin. The experimental group was injected with MIA and after 7 days was medicated with 34 mg/kg of KIT. Indomethacin and KIT were orally-medicated for each substance a total of 4 weeks, once per day. Weight-bearing on hind legs was measured every week after MIA injection. At the end of the experiment (5 weeks after MIA injection), micro CT (computed tomography)-arthrography and histopathological examinations on the articular structures of knee joint were performed. The effect on inflammatory cytokines and immunological cells in synovial fluid was measured. Volume of cartilage was measured by micro CT-arthrography. Injury to synovial tissue was measured by H & E (hematoxylin and eosin), Safranin-O immunofluorescence. Results: 1. Cytotoxicity against hFCs was insignificant. 2. KIT showed the potent full term for DPPH. 1. NO was significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and ROS was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 2. IL-6 and IL-$1{\beta}$ were significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and TNF-${\alpha}$ was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 1. In hind legs weight-bearing measurement, level of weight increased. 2. Functions of liver and kidney were not affected. 3. IL-$1{\beta}$ was significantly reduced and TNF-${\alpha}$, IL-6 were also reduced but not significantly. 4. PGE2 (prostaglandin E2), LTB4 (leukotriene B4) were significantly reduced in the KIT group. 5. MMP-9 (matrix metalloproteinase-9), TIMP-1 (tissue inhibitor of metalloproteinases-1) and Osteocalcin were significantly reduced in the KIT group. 6. Destruction of cartilage on micro CT arthrography was reduced but had no significant differences. 7. Histopathologically, injury to synovial membrane of the KIT group was decreased and proteoglycan content of KIT group was increased. Conclusions: According to this study, Kyejiinsam-tang has inhibiting effect on the progression of arthritis in MIA-induced osteoarthritis rat. Kyejiinsam-tang has anti-oxidants and anti-inflammation effects, and is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.
