This study aimed to develop processed foods that can be tailored to the tastes of consumers in countries to enter domestic and foreign markets utilizing fresh Korean pears, in which the consumption is decreasing. A survey was also conducted on three types of samples (pear jelly, pear rice cake, and pear muffin). As a result, both Korean and Chinese women aged in their 20s preferred pear muffins the most among the pear products evaluated. Pear jelly and rice cake were preferred by Chinese consumers because of their sweet taste (p<0.05). Pear rice cakes were preferred because of their texture (p<0.05). Pear muffins were not significant in all items except for odor/flavor and sweetness, but Korean consumers had a high preference for them and showed a significant preference for colors (p<0.05). Pear muffins were most familiar to both Korean and Chinese consumers showing a high willingness to purchase. An analysis of the preference inducement factors of consumers in each country of the three processed foods containing pears using Check-All-That-Reply (CATA) showed that the consumers of both countries preferred the ‘pear odor/flavor’ characteristics of pear jelly, and that pear rice cakes were preferred by Chinese consumers compared to Korean consumers. Pear muffins were preferred by Korean consumers. Overall, pear muffins are the product expected to be most suitable for female consumers in Korea and China aged in their 20s.

Purpose: The purpose of this study was to describe the illness experience of patients with short bowel syndrome. Methods: Six patients with short bowel syndrome were recruited from a tertiary hospital in Korea. Semi-structured and face-to-face interviews were conducted with the participants between April, 2018 and October, 2018. The transcribed data were analyzed using thematic analysis. Results: Three themes and nine sub-themes emerged as follows. The first theme is ‘suffering from bad symptoms caused by short bowel,’ including 1) difficult to suppress uncontrolled appetite, 2) fear of having abdominal pain at all time, and 3) having multiple diarrhea with non-digested food as sub-themes. The second theme is ‘enduring negative consequences of the prolonged disease,’ including 1) must adopt a skinny body to the bone, 2) have to be dependent on TPN, and 3) Suffer from complications such as infection and dehydration. The last theme was ‘having difficulties of living with hopelessness,’ including 1) being lack of information about the disease, 2) being hopeless of the fact that it is incurable, and 3) being nervous on endless medical bills to pay. Conclusion: Patients with short bowel syndrome are more likely to suffer from various physical, psychological, social, and financial problems. Based on the results of the study, health professionals could develop effective management guidelines. In addition, vigorous efforts such as multidisciplinary team approach including physicians, nurses, pharmacists and clinical dietitians are demanded to improve nutritional status and quality of life of the given population.

Purpose: The objective of this study was conducted to investigate the effects of rutin, buckwheat components on cell growth and anti-inflammation in adipocyte 3T3-L1 and human colon cancer cell SW-480. Methods: We cultured 3T3-L1 adipocyte and SW-480 colon cancer cell to confluence, at which time starvation was induced with SFM for 1 day. Cells were then cultured in medium containing 0, 25, 50, or 100 μmol/mL of rutin 3T3-L1 or 0, 10, 20, or 40 μmol/mL SW-480. Cell viability was measured using a cell viability kit. In addition, we examined the expression of mRNA related to inflammation. RT-PCR was used to quantity tumor necrosis factor (TNF-α), interleukin-1β (IL-1β), IL-6, inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) mRNA levels. Results: Rutin significantly inhibited 3T3-L1 and SW-480 cell proliferation in a dose and time dependent manner. Rutin also significantly reduced the mRNA expression of IL-1β, IL-6 and TNF-α at the highest dose. In addition, rutin treatment caused a significant reduction in COX-2 and iNOS mRNA levels compared to the control group. Conclusion: Overall, our results suggest that rutin has the potential to reduce inflammation, and that these effects are greater during tissue-damaging inflammatory conditions.

레이더 빔의 과대굴절현상은 수증기압과 기온의 특정한 연직적 대기 조건 하에 주로 발생한다. 과대굴절에 의해 발생하는 이상전파에코는 레이더 영상에서 강수에코로 자주 오인되기 때문에 자료품질 과정에서 미리 제거될 필요가 있다. 이를 위하여 X밴드 이중편파레이더 관측에서 비기상에코(과대굴절에코와 청천대기에코)와 기상에코의 영역에 있는 이중편파변수(차등반사도, 교차상관계수, 차등위상차) 자료들만을 수집하여, 반사도와 이중편파변수들과의 관계성 및 그룹함수에 대해서 두 에코 유형을 비교하였다. 이들 이중편파변수에 텍스쳐 기법을 적용함으로써 비기상에코를 최대한 제거하는 X-밴드 이중편파레이더용 알고리즘을 개발하였다. 전반적으로 이 알고리즘은 이상전파에코를 비교적 잘 탐지하여 제거하였으며, 또한 전라남도 진도에 위치한 S밴드 단일편파레이더 영상 자료와 비교하여 정성적으로 평가되었다.

The purpose of this study was to investigate the dietary habits of smokers and non-smokers among a few male university students residing in Changwon-si and factors that affect their smoking behavior. A self-administered questionnaire was conducted for a duration of one month in June 2015 (n=367). The results of this study showed that the breakfast skipping rate of the smoking group was significantly higher compared to the non-smoking group (p<0.001), and the smoking rate was significantly higher among those with more serious smoking problems (p<0.001). Compared to the non-smoking group, the smoking group showed significantly higher BMI (body mass index) (p<0.05) and demonstrated significant drinking habit of more liquid type yogurt among milk and dairy products and significantly more coffee mixes among fat, oils, and sugars (p<0.05). The results of multiple regression analysis showed the necessity to prepare smoking systems in school (t=－2.87, p<0.05), encumbrances to studies due to smoking (t=－3.59, p<0.001), and variables that affect smoking such as the number of close friends who smoke (t=4.17, p<0.001), BMI (t=3.08, p<0.05), and the level of problematic drinking (t=3.67, p<0.001). The results of this study suggest factors that must be considered in establishing smoking prevention education programs, anti-smoking policies, and strategies for university students.

This study investigated the factors affecting problematic drinking amongst the male university students of the Changwon area (n=367). The participants were divided into 3 groups, and undertook the self-report questionnaire survey. Based on the AUDIT (Alcohol Use Disorders Identification Test) guidelines, problematic drinking were rated as ‘no problem’ (28.8%), ‘at-risk drinking’ (41.7%), and ‘alcohol abuse’ (29.5%). Our study revealed that students living alone, indulged in more club activities, and drank more than 3 cans of carbonated drinks a day; this was significantly high on the AUDIT score (p<0.05). Participation in education was significantly higher (p<0.05), but intention to reduce the monthly alcohol consumption was significantly lower (p<0.001) in the alcohol abuse group. Recognition level of drinking cultures, drinking habits, AUDIT, and nicotine dependence were significantly higher in the alcohol abuse group (p<0.001). Recognition level of drinking cultures and nicotine dependence by the FTND (Fagerstrom Test for Nicotine Dependence) positively correlated with problematic drinking, whereas dietary guidelines and self-esteem showed a negative correlation with problematic drinking (p<0.05). Based on the results of multiple linear regression analysis, the factors affecting problematic drinking were recognition level of drinking cultures (β=0.47, p<0.001) and nicotine dependence (β=0.23, p<0.001). We conclude that implementation of health education for university students, would aid in rectifying the incorrect perception of drinking. Furthermore, both drinking and smoking should be considered simultaneously.

목적: 최근 원데이 소프트콘택렌즈 착용비율이 증가함에 따라 부작용 비율도 증가하고 있다. 이에 본 연구는 원데이 콘택트렌즈를 하루를 초과해서 착용했을 때 발생할 수 있는 여러 가지 문제점들에 대해 알아보고자 하였다. 방법: 전신질환 및 안과적 수술경험이 없고 실험의 취지를 이해하고 동의한 교정시력 1.0 이상의 남녀 23명을 대상으로 하였다. 원데이 소프트콘택트렌즈는 시중에서 가장 많이 유통되고 있는 A사 제품을 사용하였으며, 콘택트렌즈 피팅을 위한 전안부검사, 각막곡률검사, 굴절검사 후 피팅평가를 실시하여 1일, 2일, 3일 간의 자각적 만족도(건조감, 이물감, 흐림, 눈부심, 두통, 가려움증, 충혈 등)를 실시하였다. 또한 참가자의 눈 보호를 위해 3일간의 착 용기간 중에 전안부 검사를 통해 이상증상이 있을 경우 즉시 착용을 중단하였다. 결과: 원데이 일회용 콘택트렌즈 착용 1일차(12시간)는 대부분 무난하고 양호한 착용감을 보였으나, 2일차(24시간)에는 1일차 보다는 좀 더 불편한 착용감을 보였고, 3일차(36시간)에는 착용감이 급격히 떨어져 착용을 중단하는 참가자가 많았다. 1일차(12시간)~2일차(24 시간)는 자각적으로나 타각적으로나 문제가 발생하지 않았으나, 3일차 이후부터 자각증상에서 뻑뻑함과 건조감 부분에서 급속히 증상이 악화되었다. 결론: 원데이 일회용 콘택트렌즈의 착용감의 변화는 2일차부터 발생하며 렌즈의 표면침착물로 인해 3일차부터 착용자의 자각적 만족도가 급격히 낮아짐을 알 수 있었다. 따라서 원데이 일회용 콘택트렌즈는 착용기간을 준수하여야 할 것이다.

This study was conducted to evaluate the effect of site quality on allometric equations, stem density and biomass expansion factors(BEFs) in a 20-year-old Machilus thunbergii plantation. The study site was located in Jindo county, Chollanam-do, southern Korea. Total 14 trees were harvested from the good site(tree height: 6.7 m) or poor site(tree height: 4.6 m) assumed by tree height growth. Allometric equations, stem density and biomass expansion factors were calculated from the sampled trees. Site-specific allometric equations of tree components were significant(p<0.05) with diameter at breast height(DBH). Also, generalized allometric equations could be applied to estimate tree biomass regardless of the difference of site quality because of no significant effect on slope of site-specific allometric equations. Aboveground tree biomass was significantly higher in the good site(81.0 Mg ha-1) than in the poor site(46.3 Mg ha-1). Stem density was not significantly different between in the good site(0.65 g cm-3) than in the poor site(0.67 g cm-3), whereas aboveground tree and leaf BEFs were significantly higher(p<0.05) in the poor site(aboveground: 2.23; leaf: 0.42) than in the good site(aboveground: 1.82; leaf: 0.23). The results indicated that aboveground Biomass and Biomass expansion factors of a Machilus thunbergii plantation were affected by site quality.
