식물로부터 유래된 카보멘사이드를 이용한 열경화성 탄성체 합성

양진영,이상준,김건중,김영운,신지훈 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1

석유 고갈의 우려와 친환경적이면서 인체에 무해한 제품의 수요 증가에 따른 화학산업의 최근 동향은 석유 기반 원료의 사용을 줄이고, 바이오 기반 원료를 적극 활용하는 방향으로 전개되고 있다. 이에 본 연구에서는 바이오 기반 열경화성 탄성체를 합성하기 위하여 자연으로부터 얻어지는 락톤 류 중 하나인 카본(carvone)을 사용하였다. 민트나 허브에서 추출한 카본으로부터 카보멘사이드 모노머를 얻었고, 이를 개환 중합하여 양 말단이 하이드록시기(-OH)인 폴리카보멘사이드를 합성하였다. 여기에 숙신산 무수물을 첨가하여 양 말단을 카르복시기(-COOH)로 치환한 후, 아지리딘 경화제를 사용하여 고온에서 경화시키면 투명하고, 고온에 잘 견디며, 높은 신율을 갖는 열경화성 탄성체가 얻어진다. 이와 같은 일련의 과정은 원팟(one-pot) 반응으로, 생성물의 손실을 최소화할 수 있을 뿐만 아니라 에너지 또한 절감할 수 있어 산업적으로 활용할 가치가 있을 것으로 기대된다.

The purpose of this study is to examine the importance of healthy attachment formation by examining the effects of dental hygiene students‘ adult attachment patterns on depression, self-esteem, empathy, and career choice, and to present basic data for career guidance that considers individual characteristics. Students enrolled in the dental hygiene department at a university in Daejeon were the subjects of this study, and data were collected from September 14 to October 14, 2020 through self-reported questionnaires. Frequency analysis, ANOVA, correlation analysis, and multiple regression analysis were performed. As a result of classifying adult attachment styles into three types, out of a total of 158 people, 62 (39.2%) had the avoidant attachment style, 56 (35.4%) had the secure attachment style, and 40 (25.3%) had the anxiousambivalent attachment style appear. Self-esteem according to attachment type (F=26.224, p<0.0001), empathy (F=3.944, p<0.05), depression (F=12.702, p<0.0001), career indecisiveness (F=4.367, p<0.05). Based on the results of identifying the sub-factors that affect the dental hygiene and adult attachment styles of students with depression, self-esteem, empathy and career choice, this study intends to use them as reference materials for career decision taking into account individual characteristics.

Objective: Assault in the emergency room can lead to a decrease in the quality of the entire emergency medical system due to the functional deterioration and increased fatigue of the medical staff. This research tried to identify and analyze the characteristics of assault against emergency medical technicians (EMTs) working in the emergency room and establish the factors related to poor post-assault-exposure response. Methods: In this multicenter study, we conducted a survey of EMTs working in the emergency rooms. Response after assault was measured by Likert 5-point scale; the data of the participants were divided based on the median score. The demographic characteristics, hospital preparedness, and the characteristics of the assault were analyzed. Afterwards, the data of the risk factors for poor post-assault-exposure response were subjected to multivariable logistic analysis. Results: Of the 141 study participants, 84 (59.6%) were women. Most of them had experienced verbal violence (n=137, 97.2%) and physical threats (n=137, 92.2%), and 96 (68.0%) had experienced physical assault in the past year. The results of the multivariable logistic regression analysis revealed that female sex (adjusted odds ratio [aOR], 6.152; 95% confidence interval [CI], 2.687-14.120) and the increase in the number of physical assaults (aOR, 1.160; 95% CI, 1.036- 1.298) were associated with a poor response. Conclusion: Considering the importance of the EMTs in the emergency medical system and the potential adverse effects on the status of their health and services, the provision of appropriate support to female EMTs and the active intervention for attenuation of physical assault escalation in case of aggressive situations is needed. Our present results can be used for the identification and resolution of the underlying causes of these problems.

A Study on the Verification Method of Ships’ Fuel Oil Consumption by using AIS

양진영 해양환경안전학회 2019 海洋環境安全學會誌 Vol.25 No.3

Since 2020, according to the International Convention for the Prevention of Pollution from Ships (MARPOL) amended in 2016, each Administration shall transfer the annual fuel consumption of its registered ships of 5,000 gross tonnage and above to the International Maritime Organization (IMO) after verifying them. The Administration needs stacks of materials, which must not be manipulated by ship companies, including the Engine log book and also bears an administrative burden to verify them by May every year. This study considers using the Automatic Identification System (AIS), mandatory navigational equipment, as an objective and efficient tool among several verification methods. Calculating fuel consumption using a ship’s speed in AIS information based on the theory of a relationship between ship speed and fuel consumption was reported in several examples of relevant literature. After pre-filtering by excluding AIS records which had speed errors from the raw data of five domestic cargo vessels, fuel consumptions calculated using Excel software were compared to actual bunker consumptions presented by ship companies. The former consumptions ranged from 96 to 123 percent of the actual bunker consumptions. The difference between two consumptions could be narrowed to within 20 percent if the fuel consumptions for boilers were deducted from the actual bunker consumption. Although further study should be carried out for more accurate calculation methods depending on the burning efficiency of the engine, the propulsion efficiency of the ship, displacement and sea conditions, this method of calculating annual fuel consumption according to the difference between two consumptions is considered to be one of the most useful tools to verify bunker consumption.

그리스도와의 연합에 대한 논의

양진영 한국개혁신학회 2023 한국개혁신학 Vol.79 No.-

The union with Christ is a remarkable event. However, the nature of the union varies, and the results vary depending on the perspective as well as the purpose of the union. The problem is that these on-going debate run parallel to each other as they become increasing complicated. The reason being that the union with Christ is an insoluble mystery. For this reason, the purpose of this study is to emphasize and demonstrate the union with Christ through the ecclesiology of community, it is because the union with Christ does not end with personal salvation. Namely, if we are saved through union with Christ, we must of in turn bear witness to the mystery of Christ through the various gifts that we have. In addition, when we focus on the fact that the church is gradually losing its dynamics due to philosophized debate, it is important to experience the unity of the church as one body of Christ and should be the main direction of this discussion.
