In the 2000s, character animation technique is used at domestic TV character animation ads of diverse items displaying new character patterns and expression techniques of a high level. This study intends to identify the characteristics of TV character animation ads based ell character aesthetic theory and advertising rhetoric theory, and based on these findings, analyze trend and stream of expression in TV character animation ads by examining and classifying advertisements released in the past four years by items, character patterns and expression techniques. The results showed that TV character animation ads have been concentrated on confectionery, beverages and foods in the past, but the items have been diversified through the years. With reference to character patterns, personal and animal characters had made the main pattern, but recently product, virtual and composite characters are on the increase. In expression techniques, cell animation technique was found to be the most frequently used technique, which was followed by full-3D, cell and live action, cell and 3D and the clay animation technique. A trend like this suggests that TV character animation advertising items will continue to increase in line with the participation level of targets. In the meantime, personal and animal characters will continue to make the leading character pattern, while virtual and composite character patterns emerge in new forms. In expression techniques, live action combined with 30 technique and techniques using new expression materials will appear with cell animation technique as a central figure. As a whole, Korean character animation advertisement is expected to keep on growing to a new dimension in the aspect of items, character patterns and expression technique.

Purpose : The purpose of this study was to investigate the clinical features of adolescent TB. Methods : We retrospectively reviewed the medical records of the adolescents aged 12 to 18 years and who are hospitalized with the diagnosis of TB at Dong Kang General Hospital between January 2003 and December 2007. Results : Of the 29 patients who were identified, 65.5% were male. The median age at diagnosis was 16.9 years (range: 12.1-18.9 years). A tuberculin skin test (TST) was performed for 6 patients (20.7%). Among them, 5 (5 of 8[62.5%]) in the 12-15 years age group (Group A) and 1 (1 of 21[4.8%]) in the 16-18 years of age group (Group B) were TST positive, which showed that the TST performing rate decreased with age (P<0.01). Twenty-five patients (86.2%) were detected by evaluating the clinical symptoms that suggested TB and 4 patients (13.8%) were detected by screening, but no cases were detected by contact tracing. Twenty patients (69.0%) had isolated pulmonary disease. Seven patients (24.1%) had pulmonary and extrapulmonary disease and 2 patients (6.9%) had exclusively extrapulmonary disease. Most patients presented with multiple symptoms, and the most common were cough (79.3%), fever (75.9%), sputum (65.8%) and chest pain (34.5%). M. tuberculosis was isolated from the sputum of 20 patients (69.0%). The culture-positive rate increased with age (range: 62.5% in Group A to 71.4% in Group B), but the difference between the groups was not significant. Cavitary lesions were found 13 patients (44.8%). The cavitary lesion rate increased with age (range: 25.0% in Group A to 52.4% in Group B), but the difference between the groups was not significant. Four patients (13.8%) were lost during follow-up. One patient (6.9%) relapsed. Conclusion : Clinicians need to be aware of the unique features of adolescent TB, and they also need awareness of the importance of TST and contact investigation for an adult suspected of having TB for making the diagnosis of TB.

A new hydroxypropyl chitosan capable of forming a thermotropic liquid crystalline phase and two kinds of derivatives based on the hydroxypropyl chitosan (6-cholesteryloxycarbonylpentoxypropyl) chitosans (CHPCTs) and acrylic acid esters of CHPCT (CHPCTEs) were synthesized. The crosslinked films with liquid crystalline order were also prepared by photocrosslinking CHPCTE in mesophase. The liquid crystalline properties for all the samples and the swelling behavior of the crosslinked samples in acetone were investigated. In contrast with the hydroxypropyl chitosan, all the uncrosslinked cholesteryl-bearing samples farmed monotropic cholesteric phases with left-handed helicoidal structures and exhibited reflection colors over the full cholesteric range. This is the first report of a thermotropic cholesteric liquid crystalline chitosan derivative with reflection bands in the visible region. Both the optical pitches (λ$\_$m/'S) of CHPCT and CHPCTE decrease with temperature or with cholesteryl content at a given temperature. However, the λ$\_$m/ of CHPCT was larger than that of CHPCTE at the same temperature and at the same cholesteryl content. All the crosslinked samples did not display reflection colors, indicating that the cholesteric structure of CHPCTE significantly changes upon crosslinking. The two-dimentional anisotropic swelling characteristic of liquid crystalline networks was observed for all the crosslinked samples.

Accident rate in the construction industry of South Korea is increasing every year, and it represents the highest percentage among industries. This shows that activities performed to prevent safety accidents in the country are not efficient when it comes to reduce the accident rate. In order to resolve this issue, a model for the prediction of human accidents should be established. In addition, it is required a quantification study based on pattern of human accidents. Therefore, the objective of this study is to quantify uncertainty of human accidents risk and predict how to change in various circumstances by using Monte Carlo Simulation. To achieve the objective, first, pattern of human accidents was defined. Second, insurance claim payout and information of human accidents during 14 years in construction site were collected. Third, descriptive analysis is conducted to determine the characteristics of the accident pattern. Fourth, to quantitatively analyze the pattern of the human accidents, the population of each accident occurrence and payout were estimated. Finally, estimated populations was analyzed according to characteristics of distribution by using Monte carlo simulation. In the future, this study can be used as a reference for developing the safety management checklist in construction site and development of prediction models of human accident.

Reducing sugar content of persimmon fruits was increased by applying food-garbage compost Dungsi was brighter with yellow color than that of control. The Gabjubaekmok was darker than that of control with red color. It was suggested that taste of astringent was reduced because total phenol and soluble tannin contents were reduced by applying food-garbage compost. The vitamin C content of persimmon fruits during storage was higher than that of control. Stability of persimmon fruits by applying food-garbage compost and non-food garbage compost was about the same at room temperature. At low temperature, hardness of persimmon fruits was maintained for 20 days. Hardness and reducing sugar contents of persimmon fruits were increased by applying food-garbage compost. The result was shown that there was no effect on composition of persimmon fruits by applying food-garbage compost and maintaining hardness at room temperature, but at low temperature, the composition of persimmon fruits was changed.

Grafted tissues were investigated using various microscopic techniques. Pinus thunbergii was used as stock and scion and autografted by cleft graft method. Histochemically, grafting processes can be proceeded by four stages: 1) formation of necrotic layer, 2) proliferation of callus, 3) development of neo-cambium from callus, and 4) restoration of new vascular xylem. Necrotic la yer composed of pectin and lignin was gradually degraded during grafting process and disappeared when new union was formed between stock and scion. A large number of starch and lipid bodies in the cytoplasm were also gradually degraded during grafting process and disappeared at the grafting interface. Nucleus and plasmodesmata were not changed. Bubble-like callus was generated from all living parenchyma cells and from the callus. The tracheary elements differentiated from the callus had either reticulate or pit-like thickenings in the secondary walls with bordered pits. Secondary cell wall thickening occurred toward filing to the void parts between reticulated secondary wall. Tracheids formed in the secondary xylem were short with irregular wall thickness. New secondary xylem cells with swirled shapes, which developed in graft union were oriented horizontally and obliquely to axis of the stem.

자연하천과 같은 사행수로에서 발생하는 이차류는 흐름 분포를 왜곡시킴으로써, 유사이동, 하상과 제방침식, 하천의 지형변형 등에 매우 큰 영향을 미치게 된다. 또한, 이차류는 주 흐름방향에 수직으로 발생하기 때문에 자연하천에 유입된 오염물의 횡방향 혼합에도 지대한 역할을 한다. 따라서, 본 연구에서는 사행수로에서 이차류의 특성을 정량적으로 분석하고자 중심각이 $120^{\circ}$인 두 개의 만곡부로 이루어진 사행수로에서 실험을 수행하였다. 실험수로는 직사각형 단면과 자연형 단면 두 가지 형태로 제작하였으며, 자연형 단면 하상은 베타함수를 이용하여 제작하였다. 이차류의 정확한 측정을 위해 3차원 유속측정 장치인 micro-ADV를 이용하였다. 실험조건으로는 직사각형 단면과 자연형 단면에서 평균수심과 유량을 달리하여 실험을 총 12회 수행하였다. 실험결과, 직사각형 단면수로에서의 주 흐름의 최대유속선은 수로의 가장 짧은 경로를 따라 발생하였는데, 이는 Shiono와 Muto (1998)의 결과와 일치한다. 자연형 단면 수로에서의 주 흐름은 직사각형 단면 수로에서의 주 흐름 거동과 비슷한 양상을 보였다. 이것은 실제 자연하천 만곡부에서의 주흐름 거동(최대유속선이 최심선을 따라 발생)과는 상이한 결과였다. 그 첫째 원인은 실험수로의 조도가 일반적인 실제하천의 조도를 상사법칙에 맞게 계산한 값보다 작았기 때문이다. 그리고 두 번째 원인은 실험수로의 하폭대 수심비율은 실제하천의 하폭대 수심비율보다 컸기 때문인 것으로 사료된다. 이차류의 정량적인 분석을 위해 각 측정지점별로 횡방향, 수심방향 유속을 그려본 결과, 직사각형 단면에서는 하나의 셀이 존재하는 반면에 자연형 단면에서는 셀이 두개 존재함을 알 수 있었다. 이는 자연하천에서도 발견되는 현상이다. 실제 자연하천에서는 주 셀이 바깥제방 셀보다 큰 형태를 보이지만, 실험수의에서의 셀의 형태는 주 셀보다 바깥제방 셀이 더 크게 발생하는 것으로 밝혀졌다. 이는 앞서 언급한 바와 같이 조도가 작음으로 인한 것으로 판단된다. 이차류 강도를 계산한 결과, 직사각형 단면 수로의 최대값은 두 번째 만곡 유입부지점(U2)에서 가장 크게 나타났으며. 자연형 단면 수로에서 최대값은 두 번째 만곡을 조금 지난 (U4)지점에서 가장 크게 나타났다. 자연형 단면에서는 하폭 대 수심비가 커질수록 이차류강도가 크게 나왔으나, 직사각형 단면에서는 반대로 나왔다. 그리고, 자연형 단면의 이차류 강도는 직사각형 단면보다 크게 나타났다. 특히, 직사각형 단면의 이차류강도는 첫 번째 만곡부분보다 두 번째 만곡부분이 더 크게 나타나는 현상만 보였지만, 자연형 단면의 이차류 강도는 앞서 언급한 특징 외에 만곡부에서 증가하고, 직선부에서 감소하는 주기적인 형태를 보였다.

최근 사회의 다변화, 고령화 및 소비자의 다양한 욕구 증대 등으로 인하여 세분화된 소비계층을 겨냥한 다양한 신제품들이 출시, 판매되고 있는 반면, 일반 백색시유를 제외하고는 제품의 라이프사이클이 크게 줄어드는 경향을 보이고 있다. 건강기능식품 시대의 도래와 함께 첨단 기능성 소재들이 속속 등장하고 있으며, 유가공업계도 이들 소재를 응용한 연구개발과 공정개선을 통한 신제품 출시에 박차를 가하고 있다. 그러나 음용유 시장에서 절대적인 비중을 차지하고 있는 시유부문은 저출산율과 수입개방 등의 악재로 인하여 점차적인 감소 추세에 접어들고 있다. 따라서 국내 유가공업체는 원유소비 증대와 유제품 경쟁력을 확보하기 위해 유제품의 다양화, 고급화를 위한 기술개발 및 유제품의 적극적인 홍보 등의 전략이 필수적이다. 이를 위해서는 종래 단순가공에 의한 유제품 생산에서 탈피하여 새로운 공정 개발, 신물질 탐색 등으로 생산비 절감, 수율 증대, 다양한 형태의 유제품 개발, 그리고 기능성 소재의 탐색 등 건강 지향적 기능성 식품 개발에 노력을 해야 할 것이며 국공립 및 사립대학교 및 정부 출연기관과 일반 유업체의 공동과제 실시 확대로 기능성 식품에 대한인식제고가 필요할 것이다. 또한, TV 매체를 통한 홍보, 우유의 교과서 반영, 자조금 활성화 등으로 어릴 때부터 우유 먹는 습관을 형성하여 시유 소비기반 확대를 도모해야 할 것임과 아울러 교육당국과 협력하여 학생과 영양교사를 대상으로 한 우유에 대한 체계적인 교육프로그램 실시 및 중 ·고등학교 급식화대 추진 등 관련 기관과의 협력체계 구축을 통한 낙농진흥활동을 전개하여야 한다.유아의 창의성수준을 더 높게 평가하였다. 그러나 아버지와 교사간 평가의 상관은 유의하지 않았는데 이는 아버지의 평가수준이 매우 객관적인 것은 아님을 시사한다. 셋째, 창의적인 유아와 일반 유아 아버지 양육태도에서는 유의한 차이를 보였는데 특히 애정-적대요인과 자율-통제요인에서 창의적인 유아와 일반 유아간의 차이가 있는 것으로 나타났다. 넷째, 유아의 창의성과 아버지 양육태도간의 상관관계분석결과 애정적 양육태도와 유창성, 독창성간의 상관이 유의하였다. 집단별 분석시 창의적인 유아를 둔 아버지의 양육태도와 유아의 창의성간에는 상관이 없는 것으로 나타났고, 일반 유아의 아버지 양육태도와 유아의 창의성간의 상관에서는 아버지 양육태도의 성취-비성취 요인에서와 창의성제목의 추상성요인에서 상관이 있는 것으로 나타났다. 따라서 창의성이 높은 아동의 아버지의 양육태도는 일반 유아의 아버지와 보다 더 애정적이며 자율성이 높지만 창의성이 높은 아동의 집단내에서 창의성에 특별한 영향을 더 미치는 아버지의 양육방식은 발견되지 않았다. 반면 일반 유아의 경우 아버지의 성취지향성이 낮을 때 자녀의 창의성을 향상시킬 수 있는 것으로 나타났다. 이상에서 자녀의 창의성을 향상시키는 중요한 양육차원은 애정성이나 비성취지향성으로 나타나고 있어 정서적인 측면의 지원인 것으로 밝혀졌다.징에서 나타나는 AD-SR맥락의 반성적 탐구가 자주 나타났다. 반성적 탐구 척도 두 그룹을 비교 했을 때 CON 상호작용의 특징이 낮게 나타나는 N그룹이 양적으로 그리고 내용적으로 더 의미 있는 반성적 탐구를 했다용을 지원하는 홈페이지를 만들어 자료 제공 사이트에 대한 메타
