This study was conducted on 4th and 5th grade elementary school students in Daegu, Korea for the purpose of promoting health and proper dietary habits. A children food safety education program was developed and its effects evaluated on 4th and 5th graders (3,932 students for 4th year, 4,438 students for 5th year) at 46 elementary schools, which were under the jurisdiction of the four educational bureaus of Daegu city. Education was conducted in accordance with an education design plan, of which there were two goals, including know the contents of 'special act on children's dietary life safety management' and 'practice proper hand-washing'. 'Special act on children's dietary life safety management' was explained, and the education curriculum included proper hand-washing for prevention of food poisoning, quality certification mark on children's favorite foods, harmful foods such as unsanitary and adulterated foods, and green food zone. Flash songs, PowerPoint, 'glitter burger' notice note, and banner were used as education media. It was found that the awareness level of items related to 'special act on children's dietary life safety management' increased significantly after education (p<0.001). 'Necessity of nutrition education and children's food safety' also increased significantly (p<0.05) after education. Lastly, children answered that they washed their hands more often after education (62.9%) than before (60.7%).

The purpose of this study was to compare the emotional responses of people with visual disability with those of normal people and to understand their similarity or differences in order to apply the new understandings into the future research on Web Accessibility Guidelines. For this purpose, a Web survey system was developed using 15 auditorial stimuli prepared based on the Media Taxonomy and 11 emotion measuring criteria selected from the literature review. After developing the system, emotional responses of 31 people with visual disability and 53 normal people were collected through the Web. The results of the survey showed that the emotional responses of people with visual disability were similar to those of normal people, although there were some exceptional cases. Therefore, it is clear that emotional needs of people with disability should be taken count of in the Web accessibility discussions and further in-depth studies on the emotional characteristics of people with disability are necessary.

With the increasing use of the SNS, WOM(Word of Mouth) has become an even more powerful and useful resource for consumers and marketers. In this paper, we investigated the effects of message polarity (positive, neutral, negative) and type (factual, evaluative) on WOM through SNS (twitter). A total of 13.4 million twitter messages were collected and 1.0 million retweeted messages were analyzed. The results showed that message orientation, type, URL and hashtag have a significant (<0.01) effect on retweet counts and the interaction between message orientation and other factors were observed. It also observed that message type, URL and hashtag have significant (0.05) relationships with retweet speed.

본 연구는 미 L-A에 거주하는 한국이민 노인들의 특성을 파악하고, 그들의 생활만족도에 기여하는 결정요소들이 무엇인지 가려내며, 그 얻어진 결과를, 동일한 시각과 접근으로 시도되었던 미국 노인들에 대한 선행연구들의 결과와 비교 분석하였다. 연구는 1986년 12월에서 1987년 2월까지 3개월간 미 L-A 카운티에서 거주하는 55세 이상의 한국 이민노인 390명을 대상으로 설문지 조사를 실시하여 그중 192명을 자료분석에 사용하였다. 단계별 중다 회귀분석의 결과, 활동성의 제약정도, 결혼상태, 재정적인 안정, 교육정도, 연령증가 등 5가지 변인들의 특별히 한국노인의 생활만족도가 강한 연관성이 있었고, 반면 자신들이 평가한 건강상태, 지인과의 사회적인 상호작용, 미국거주 년한 등은 노후생활의 안녕에 전혀 직접적인 영향력을 행사하지 못했다. 그러나 자신들이 평가하는 건강상태는, 활동성의 제약 등과 같은 다른 변인에 미치는 효과를 통해서 생활만족도에 간접적으로 강하게 영향을 미치고 있었다. 이러한 결과를 선행연구에서 나타난 서구나 미국노인의 생활만족도 결정의 세 요인인 건강상태, 사회경제적 지위, 사회적 활동성과 비교해 볼때, 사회적 활동성과 연령증가 변인에서 서로 상반되는 대조를 보이고 있었다. 즉, 백인노인들은 나이가 듦에 따라 생활만족도가 낮아지거나 혹은, 연령증가와 생활만족도 사이에 별로 유의할 만한 관계를 보이지 않고 있으나, 본 연구에서의 한국노인은 나이를 먹으면서 오히려 생활만족도가 높은 것으로 나타났다. 한편, 사회적 활동성은, 백인노인의 생활만족도에 긍정적 혹을 부정적으로 가장 강하게 영향을 미치는 요인중 하나임에 반하여, 한국노인들은 이것이 자신들의 생활만족에 중요한 것이라 믿고는 있었지만 실제 통계학적으로는 영향력을 행사하지 못하는 요인이었다. 주거환경(자식과의 동거여부) 역시, 이제껏 한국사회에서 기대되어왔던 통념과는 달리, 한국노인의 생활만족도에 아무런 영향을 주지 못하고 있었다.

Fracture of mandible is the most frequent fracture among many types of maxillofacial fracture, and reduction of mandible fracture is performed using various methods of treatment to maintain bonding strength of fractured bone. Among these treatment of bone fracture, a semirigid fixation method which can reduce the period of intermaxillary fixation using metal mini plate under general or local anesthesia is spotlighted these days. The metal mini plate used during this semirigid fixation procedure is Titanium which is bio-inactive one and was used widely, but because the side effect of fracture reduction using titanium have been demonstrated recently, fracture reduction using biodegradable plate become to attract people's attention. The purpose of this study was to report the clinical case and review of the literature with the reduction of mandible fracture using biodegradable plate.

A 13-year-old, 4.2 kg female poodle was referred for failure of first bilateral mandibular surgery at a local animal hospital after pathologic fracture. Surgery was performed with 2.0-mm miniplates/screws and porcine cancellous bone grafts. In addition, because of the large size of the right segmental defect, a barrier absorbable membrane was employed for guide bone regeneration on right mandible. After surgery, follow-ups performed at 1 day, 1, 4, 8, and 12 weeks; there were no signs of dental malocclusion, nonunion or soft tissue infection. However, a 1-year long-term follow-up showed nonunion in the left mandibular fracture site for which a collagen membrane had not been used. It is considered that use of porcine bone graft with barrier absorbable membrane may be effective for the repair of mandibular nonunion in a geriatric dog.

To prevent corruption, waste, and abuse in national governance, audit agencies are established and granted significant authority and responsibilities, including ensuring their independence. However, questions have been raised about who oversees these agencies and addresses issues or misconduct that may arise within them. In the United States, to address this oversight concern, the Inspector General Act was enacted, creating an audit community called the Inspector General Community. This community comprises various audit agencies and promotes compliance with standards and investigates potential wrongdoing by audit personnel. It fosters a culture of independence and collaboration among diverse stakeholders, such as Congress, the President, the Government Accountability Office, and agency leadership. In light of this successful approach in the United States, this research seeks to study and apply similar oversight mechanisms to audit agencies in South Korea. There is a need to develop the relationship between oversight bodies and parliament in terms of improving the efficiency and effectiveness of government operations. Accordingly, this paper studies this American case and presents efficient policy measures for the supervisory system to be applied to Korea's audit organizations. It aims to identify policy insights for effective supervision, ensuring independence, and fostering a collaborative culture within our audit institutions. Therefore, domestic interest and research on this matter are essential to enhance our audit mechanisms and achieve efficient governance.

Objective: Intraoral noncompliance upper molar distalization techniques have gained in popularity and have subsequently found to be successful in Class II correction. The aim of the present study was to introduce a screw supported intraoral distalization appliance and investigate its efficiency. Methods: Twenty-one subjects (11 females, 10 males; average age of 14.9 years) with Angle Class II malocclusion participated in this study. Two screws were inserted behind the incisive foramen and immediately loaded to distalize the upper first molars. An intraoral screw supported distalization appliance was used to distalize the upper molars in order to achieve a Class I molar relationship. Skeletal and dental changes were evaluated using cephalometric and three-dimensional (3D) model analysis. Results: Upper molars were distalized 3.95 mm on average and a Class I molar relationship was achieved without any anchorage loss. The upper molars were tipped only $1.49^{\circ}$ and the upper right and left molars were rotated only $0.54^{\circ}$ and $0.74^{\circ}$ respectively which were statistically non-significant (p > 0.05). Conclusions: The newly designed screw supported noncompliance distalization appliance was found to be an effective device for achieving bodily molar distalization without any anchorage loss.

우리나라에서는 70년대 이후 컨테이너 수송체계가 도입되어 운영되어 왔으나 차량의 급격한 증가와 더불어 컨테이너 수송체계는 도시교통에 있어서 많은 문제를 야기시키는 것으로 논란이 되고 있다. 특히, 부산항은 우리나라 최대의 국제 무역항으로써 전 컨테이너 수송화물의 90%이상을 처리하고 있고, 또한 수출입항으로서 제 역할을 다하고 있으나 낮은 도로율(12.45%)과 산재해 있는 30여개의 Off-Dock CY로 인해서 도심을 통과하는 컨테이너 수송차량은 많은 교통문제를 유발시키고 있다. 본 연구는 1) 부산시에 산재해 있는 30여개의 Off-Dock CY에 이르는 주요 도로상에서 컨테이너 수송량의 신간별 분포에 따라 컨테이너의 운행시간대를 첨두 시간대, 비첨두 시간대 및 심야 시간대로 분류하여 각 시간대별 평균 수송 시간 및 교통 체증으로 인한 수송 지체수준을 확인하였고, 2) 컨테이너 전용부두로 부터 Off-Dock CY에 이르는 도시 고속도로 및 주요간선도로상에서의 수송시간 및 수송 지체수준을 비교 분석하였으며, 3) 마지막으로, 효율적인 컨테이너 수송체계를 위한 최적 수송시간대 및 도로체계를 제시할 수 있었다. 특히, 컨테이너 수송시간 및 지체수준은 각 운행 시간대에 따라 현저한 차이를 보이고 있었는데, 심야 시간대를 이용하여 컨테이너 수송을 할 경우에는 다른 시간대에 비하여 50%정도의 수송시간 절감효과를 기대할 수 있었으며, 도시 고속도로를 이용할 경우에는 도시 간선도로에 비하여 30%정도의 수송시간을 절약할 수 있었다. 따라서 도시지역의 교통체중을 완화시키기 위해서 심야 시간대에 보다 많은 컨테이너 수송차량이 이용할 수 있는 컨테이너 수송체계가 확립되어야 하고, 산재해 있는 Off-Dock CY를 몇개의 ODCY그룹이나 단지까지 컨테이너 전용 고속도로의 건설이 바람직하고 생각된다.리구에서 조사한 결과 $10^{-3}$ M MGBG 단독 처리구에서 에틸렌 생성량이 가장 높았으며, spermidine과 spermine의 함량은 가장 낮았다. 부정근 형성능이 다소 회복된 $10^{-3}$ M MGBG+ $10^{-5}$M spermine 혼합처리구에서의 에틸렌 생성량은 대조구보다는 다소 높게 나타났다. 부정근 회복능이 가장 높았던 $10^{-3}$ M MGBG+ $10^{-5}$ M spermine + $10^{-4}$ M Cocl$_2$ 혼합처리구에서 에틸렌 생성량은 가장 낮게 나타났으며, polyamine 함량은 가장 높게 나타났다.(Cyperaceae), 명아주과(Chenopodiaceae) 같은 풀들이 하구언(estuary)의 해안가에 주로 서식하였던 것으로 나타났다. 이 시기동안에 해양성조류인 와편모류와 담수성 조류가 동시에 다양하게 산출되는 것은 하구언 퇴적환경이었음을 잘 지시해 준다. 제II화분대(고도, 43.72{\sim}3.36\;m$)가 시작되면서 혼합림은 침엽수림으로 바뀌었으며, 낙엽활엽수들의 서식지가 2엽소나무로 대치되면서 침엽수가 주요 수종을 이루었던 것으로 나타났다. 아마도 이런 산림형태는 자연 기후환경변화 뿐만 아니라 인간간섭에 의해 나타난 결과로 생각된다. 이 시기에 경작식물인 벼과(Gramineae), 옥수수(Zea), 메밀(Fagopyrum)과 논밭의 뚝 등지 에서 서식하는 돼지풀(Ambrosia) 등이 처음으로 산출되는 것으로 보아 인간간섭이 행해졌음을 잘 뒷 받침해준다. 또한 담수성 조류는 변함없이 산출되는 반면, 해양성조류인 와편모류가 산출되지 않는 것으로 보아 해안환경에서 다소 멀 어진
