The purpose of this research is to analyze relationships among the habitual life, stress, and constipation and to help prevent and improve the constipation among women's university students. This is a descriptive interrelated research that has targeted women's university students. The data had been collected for 10 days, from December 22, 2003 to December 31, 2003. The survey was carried out to the 295 women's university students that had been randomly selected by visiting four-year-course colleges and universities in Seoul. The survey consists of 78 questions: five questions on the general trait, 11 questions on the habitual life, 51 questions on the stress, and 11 questions on the constipation. There are seven questions on the dietary life, four questions on exercising, and Shin Jung Ran's survey(2003) and Lee Ji Jung's survey(2001) was used as a reference. Yoon Ho Yul's five grade stress barometer(1996) was also used to measure the amount of stress. The collected data was analyzed by a real number, percentage, the arithmetical mean, the standard deviation, t-test, x²test using SPSS 10.00 for Windows Program. Results are as follow 1. Four to six cups of daily water intake was the highest by 50.0%. Students not have breakfast(55.7%) mostly because they did not have enough time(62.6%). Dinner was the most overeated meal by 72.3% and the most preferred food was meat by 42.0%. In the questions related to exercising, more than half of the students answered that they hardly do not exercise(58%), work out for less than 30minutes(67.3%), and exercised lightly(75.3%). 2. Students were suffering from stresses due to the personal relations(51.36±14.0426), scholastic achievement and personal direction(24.93±8.3037), financial conditions and family matters(20.28±8.1718) and social circumstances(2.7262). 3. In the defection part, the student's reply that they have more than five times of bowel movement on a weekly basis(48.3%), and that it takes three to five minutes to defecate(41.3%) were the highest. More than half of the students answered that their one time excrement quantity was between 30 grams to 60 grams(72.3%) and that it was normal(68.7%). In a question asking how it feels after the defecation(students were allowed to choose more than one answer), relieved and refreshed was the highest by 66.6%, an uncomfortable followed by 42.8%. 4.4% of the students answered that they suffer from strong abdominal pain during the defecation. The rest of the students answered that they do not have stomachache or that it was normal. The students were classified into the constipation group of 103 people(34.9%) and the normal group of 192 people(65.1%) under the devised definition of this research. 4. Students that live in dormitories and do their own cooking were more likely to have constipation than those that live in private residence or in a lodgins. 5. The research showed that there is a mutual relation between water in a day intake and the constipation. It means that the lesser water students drink, the more they suffer from the constipation. The number of times a student had a meal everyday and the constipation was interrelated. If a student had lesser or irregular meals in a day, they had more constipation. Preferred food and constipation was also interrelated. Students that preferred vegetable, fruit, and dairy products were more likely to belong in a normal/general group. 6. By dividing the stress factors into the lower categories, we were able to see that the total stress(t-2.063, p-0.040), personal relations(t-2.316, p-0.021), scholastic achievements and personal directions(t-20127, p-0.034) had mutual relation with the constipation. The constipation group(120.27±30.2708) was suffering from stronger level of stress than the normal group(112.97±28.1466). Through this study, we were able to verify that the few general traits, habitual life, and stress of the women's university students have mutual relations with the constipation.

The purpose of this study was to compare the shear bond strength and failure type of various adhesives in indirect bonding technique. Five types of orthodontic bonding adhesives - ES(Excel sealant), EP(Excel paste), EA(sealant and past), T(Transbond XT sealant), L(Light bond sealant) - were used in this study. Metal bars(70×7×7㎜) were milled and sand-blasted with 50㎛ alumina and then coated with resin. resin blocks(3×4×5㎜) were made and bonded to the resin-coated metal bars with various adhesives. Shear bond strengths were measured by an universal testing machine. The film thickness, interface region. Self-curing resin, EX(Excel sealant) showed the greatest shear bond strength(22.82±3.05 ㎫) and self-curing resin, EP(Excel paste) showed the lowest shear bond strength(13.91±2.70 ㎫). The shear bond strength of self-curing resin, EA(sealant and past : 20.94±0.92 ㎫) was similar to those of light-curing resins, T(Transbond XT sealant : 20.90±2.34 ㎫), L(Light bond sealant : 18.12±1.63 ㎫) group. Most of the failure occurred between the resin coated metal bars and sealant regardless of the adhesives.

Mun Hee Jeon,Cheol Seung Kim,Kyu Dam Han,Mi Jin Kim 대한혈관외과학회 2022 Vascular Specialist International Vol.38 No.1

Purpose: The midline catheter (MC) is a peripheral venous access device with the catheter tip located in the axilla and available for mid-term intravenous (IV) therapy. This study evaluated the efficacy and clinical outcomes associated with the placement of MCs with an integrated wire-accelerated Seldinger technique for IV access. Materials and Methods: A retrospective review was conducted at a single center in South Korea between March 2020 and July 2020. Consecutive patients in whom MC insertions were performed by vascular surgeons were enrolled. The outcomes included catheter indwelling time and incidence of catheter-related adverse events. Results: Ninety-five patients (117 catheters) were included in the study. The total indwelling time was 1,964 days, with a median of 16.7 days (range, 0-76). The complication-free catheter rates at 5 and 28 days were 92.9% and 65.5%, respectively. Overall, 32 (27.4%) catheters were removed due to complications; however, major complications, such as symptomatic deep venous thrombosis and catheterinduced bloodstream infections, were confirmed in only 3 (2.6%) catheters. A common reason for premature catheter removal is inadvertent removal owing to patient inattention. A high body mass index and female sex were identified as risk factors for short indwelling times and complicated premature catheter removal. Conclusion: MC insertion is a simple and operator-friendly procedure with a low rate of major complication. It enables mid-term IV treatment through a single procedure if there are no specific complications, thereby improving quality of life of patients during hospital stay.

The purpose of this study is to investigate whether there are differences in physique characteristics between the excellent domestic player groups in each sport player's, to prevent epidemiologic damage of musculoskeletal system and to provide fundamental data to improve performances for players. This study has performed for total 60 student players from Y University in Yongin, Gyeonggi-do, consists of 20 Kendo players, 20 Judo players and 20 Taekwondo players. We measured the length and circumference of arm, leg, body using Martin anthropometer to collect the data for 3 groups. There was significant difference in lower left arm length between player groups(p<.01), and Kendo players' right side femoral were longer than other 2 groups for leg length measurement(p<.01). Judo players' circumference for right/left stretched arm/bent upper arm were thicker than other 2 groups(p<.01). Taekwondo players' chest circumference were smaller than other 2 groups(p<.01), and Taekwondo players' right/left femoral circumference were thinner than other 2 groups(p<.05). From this study, it was found that there are physique characteristics differences between the Kendo, Judo and Taekwondo player groups. This indicates that repeated exercise for each sport player causes physique change, and it may cause epidemiologic damage of musculoskeletal system. It is recommended to perform balancing exercise prior to main exercise.

Hee Mun Chae,Bo Ram Jeon 강원대학교 산림과학연구소 2017 강원대학교 산림과학연구소 학술대회 Vol.2017 No.11

The survival rate of tree after forest fires is very important for forest fires management such as forestation plans after forest fires. This study was carried out to analyze the survival rate of Pinus densiflora tree which is one of the important economic species in Korea after forest. It is necessary to continuously monitor the tree for judgment of tree survival during 3 years after the forest fire. Therefore, this study will be analyze the survival rate of the pine tree after the forest fire in the next 3 years on burned area(Dogye-eup, Samcheok-si, Gangwon-do, Korea) by forest fire in 2017 year. As a method to analyze the survival rate of trees, the height of bark char(windward side and leeward side) formed on the tree stem and the crown scorch of the burned trees measured and study areas were selected on burned area by surface fires excepts trees were completely damaged area by the crown fires. As a result of analysis of 200 pine trees damaged by forest fire, the tree with high bark char height and crown scorch ratio were more likely to die and continuous monitoring over the next three years is necessary.

Hee Mun Chae(채희문),DU Sik Jeon 한국생물환경조절학회 2008 한국생물환경조절학회 학술발표논문집 Vol.17 No.1

We investigated the potential impact of climate change on people-caused forest fire occurrence in South Korea. Logistic regression analysis methods were used to develop daily fire occurrence prediction models for each of nine study areas. These models were then coupled with climate scenario data produced by two General Circulation Models (CCCma and CCSR/NIES) to predict future people-caused fire occurrence in those nine areas. Our results suggest the number of fire days will increase by roughly 7 to 58% depending upon the district.

The Analysis on Forest Fire Occurrence Characteristics by Regional Area in Korea from 1990 to 2014 Year

Jeon, Bo Ram,Chae, Hee Mun Institute of Forest Science 2016 Journal of Forest Science Vol.32 No.2

Understanding regional characteristics in forest fire occurrence is important to establish effective forest fire prevention policy in Korea. This study analyzed the characteristics of forest fires occurred in 16 administrative districts for recent 25 years (1990~2014) to examine regional characteristics in forest fire occurrence. Forest fire occurrence reflects regional characteristics depending on climatic factors as well as region's society-cultural factors. Results showed that the first cause of forest fire occurrence was carelessness by human activities throughout all administrative districts, however, the second cause depends on regional characteristics. As the results of forest fire occurrence period analyzed for 10 days, the most forest fires occurred in the southern region during January to March, while forest fires in the northern region occurred mostly during March to April. We classified forest fire occurrence patterns into three types (centralized: Gyeonggi-do, dispersal: Busan, horizontally distributed: Gyeongsangnam-do) by multi-temporal analysis for forest fire occurrence period.
