  • This study examined the purchasing behavior and satisfaction of people with convenience store PB foods. The factors affecting the purchasing behavior and the overall satisfaction with the convenience store PB foods were examined. This study first found that the purchasing motivation of PB foods is the cheaper price than NB foods. Second, age is a statistically effective variable for the visit frequency at the convenience store and gender and age are effective variables for the purchase frequency of PB foods. Third, there is a statistically positive correlation of convenience store brand preference with the PB food brand preference for 6 food categories. Next, in terms of the attribute-level satisfaction, the most satisfied areas are diverse food groups and diverse food taste and the least satisfied areas is price. This is followed by taste and design/packaging influence overall satisfaction. From this analysis, the following suggestions were drawn. First, because consumers are likely to be matched convenience store brand preference and PB food brand preference, advertising is necessary to ensure that the consumers continue to visit the convenience store. Second, product improvement by increasing the quality should be designed to motivate the major consumer group of people in their 20s and 30s. Finally, to boost PB food satisfaction, the industry should improve the taste and design/packaging.

  • 오늘날 열대림 면적의 급격한 감소, 지구온난화등 지구환경 보전의 관점에서 이들 목재이외의 자원의 활용 및 양마와 같은 새로운 비목재자원 개발의 중요성이 재인식되기에 이르렀으며, 이 가운데서 양마는 생장이 라르고 수확량이 크며, 목질부의 단섬유는 물론 긴 섬유장을 가진 인피부섬유로 구성되어 있고, 실리카함량도 매우 적어, 특히 산림자원이 부족한 개발도상국에서 펄프.제지용 자원으로서 주목되고 있다. 양마가펄프.제지용자원으로서 오늘날과 같은 세계적 주목을 받게 된 것은 미국 농무성 북부지역연구센타 에서 이루어진 “새로운 섬유작물”에 관한 기초연구에서 양마가 제지용 섬유작물로서 높이 평가되고 있다. 양마의 경우 인피부는 비교적 리그닌함량이 적고, 목질부는 활엽수재에 가까운 리그닌을 함유하고 있는데다, 섬유형태에 있어서도 인피부와 목질부간에 큰 차이가 발견된다. 본 연구에서는 양마를 중성아황산법으로 전처리하여 제조한 반화학펄프로 부터 제조한 종이의 광학적 성질을 검토하였다 펄프의 광학적 성질은 원료의 화학적 조성,섬유의 형태, 부위.화학적 처리정도, 원료의 저장기간 및 충전제의 첨가에 따라 크게 영향을 받았다. 장섬유와 낮은 리그닌함량을 가진 전간부 펄프시트는 불투명도가 낮았으며, 목질부 펄프로부터 상대적으로 밀도가 다소 높고, 불투명도도 높은 종이를 만들 수 있었다. 펄프원료의 저장기간이 백색도를 낮추었으며, 불투명도에는 그다지 영향하지 않았다. 약품전처리 및 표백이 백색도 및 불투명도에 크게 영향하였고, 특히 충전제 첨가로 광산란을 증가시켜 불투명도가 높은 종이를 제조할 수 있었다.6. CL종의 난황콜레스테롤 수준에 대한 계란의 일령 상호간에는 전체적으로 상호간에 차이가 없었다. 7. 26주령시 혈중콜레스테롤 수준은 CL종이 다른 두 육계종들 보다 유의적 (P$\leq$0.05)으로 높았다. 8. 성별간 혈중콜레스테롤 수준의 차이는 CL종, BR1 및 BR2 중에서 CL종에서만 나타났으며, 수컷은 암킷보다 혈액 100 mL당 약 90 mg이 낮았다.구체적인 생화학적인 연구가 이루어져야 될 것으로 여겨진다.야 할 것으로 사료된다. 냉장 저장을 하고 저장기간이 길어질 경우는 냉동저장을 사용하는 것이 바람직하다고 생각된다.S, FOS나 말티톨로 대체된 스폰지 케익은 설탕 100% 사용한 케익과 비교하여 크게 나쁘지 않거나 휠씬 나은 특성을 보이므로 스폰지 케익 제조에 그들의 이용이 가능함을 확인하였다.thione 같은 다른 항산화제의 절약 효과, CYP2El의 유도 저하를 통하는 것으로 생각되며 그중 어떤 것에 가장 큰 영향을 받는 지는 아직 알려지지 않았고 더욱 많은 연구가 요구된다.우와 사료에 $\omega$3계 지방산 급원을 첨가, 동물에게 이행시켜 $\omega$3계 지방산 강화식품을 제조하는 두 가지 방법이 있을 수 있는데 전자는 통조림, 과자, 건강보조식품류에 다용되며 후자는 다양한 기능성 축산식품에 활용되고 있다. $\omega$3계 지방산 강화 축산식품에는 돼지고기, 우유, 치이즈, 계란, 분유, 햄 등 다양한 제품에 활용, 개발되고 있으며 최근에는 이러한 식품 개발에 더욱 박차가

  • The present study aimed to calcium (Ca), iron (Fe) and zinc (Zn) contents were compared with reference values indicated on the nutrition label of nutrition emphasized food. Also, this paper will briefly review and evaluate what is currently known about Fe-Zn and Ca-Fe interaction. Ca, Fe or Zn-emphasized product, including cereal, snack, soy milk, chocolate product, other cocoa product, sugars product, beverage and tea were analyzed. The contents of Ca, Fe, and Zn in samples after dry-ashing were examined by ICP. The measured Ca (n = 42), Fe (n = 13), Zn (n = 6) values were ranged 87~176%, 98~167%, 98~275% of reference value indicated product, respectively. All samples were ranged more than 80% of the reference value, which were complied with food regulation. High intake of Ca has been shown to adversely affect Fe absorption and the negative effect of Fe on Zn absorption is well known. Therefore, it is important to consider Ca-Fe and Fe-Zn absorption interaction, when Ca, Fe or Zn-emphasized product produce and nutrition labeling policy should be managed regularly with continuous monitoring.

  • This study examines the effect of pay dispersion on labor productivity by focusing on the inflow of newcomers into the tournament and the outflow of stayers from the tournament. According to tournament theory, the expansion of pay dispersion within the organization contributes to enhanced organizational performance by attracting high performers externally and by removing low performers internally within the organization. However, previous studies regarding tournament theory have overlooked the participant aspects. Therefore, this study explores how external hiring and involuntary turnover influence the effect of pay dispersion on labor productivity. This paper hypothesizes that pay dispersion will have a positive effect on labor productivity. Moreover, this paper predicts that the inflow of new competitors will strengthen the positive effects of pay dispersion on labor productivity, whereas the outflow of incumbents will weaken this relationship. Empirical results showed that pay dispersion increased labor productivity and the inflow of newcomers strengthened this positive relationship. However, contrary to our prediction, the outflow of incumbents weakened the positive effect between pay dispersion and labor productivity. These theoretical arguments and empirical findings highlight the proper conditions should be equipped to practically achieve the positive effect of pay dispersion on labor productivity.

  • Depression in the medically ill is a common clinical problem that primary physicians and psychiatric consultants encounter. Treatment of such patients begins with a careful evaluation of the patient's medical and psychiatric conditions. The assessment of depression in the medical patients requires a multidimensional approach. Psychological instruments are also used as a method of assessment in these patients. First of all, what the therapists have to do is to find and remove organic causes. Psychosoical treatment includes dealing with the patient's resistance and despondency relevant to physical diseases. For biological treatment, it is important to select appropriate antidepressants. Therapists should be familiar with the side effects of the antidepressants as well as the patient's primary depressive symptoms, pharmacokinetics and pharmacodynamics of the available agents. In addition, special attention should be paid to the potential for drug-illness and drug-drug interactions. Tricyclic antidepressants can be still effectively used for patients with pain disorder, although a variety of new antidepressants such as selective serotonin reuptake inhibitors (SSRI), bupropion and venlafaxine could have more benefits in depression of the medically ill. However, electroconvulsive therapy can be recommended for refractory cases of depression in patients with medical illness.

  • Purpose: This study was conducted to analyze food consumption behavior of women by marital status based on the 2015 consumer survey data on Food Consumption Behaviors of the Korea Rural Economic Institute. Methods: We analyzed data describing 3,312 women aged 19 ~ 75 who were the main buyers of foods in their household. The food purchase patterns, dining-out behavior, and use of food-delivery and take-out were investigated. Results: Overall, 40.5% of unmarried women shopped for food once per week and 37.4% spent 200,000 ~ 400,000 won per month. Additionally, 43.1% of married women shopped 2 ~ 3 times per week and 26.6% spent 400,000 ~ 600,000 won (p < 0.0001). Dining-out frequency and one-time cost per person of dining-out for unmarried women were higher than those for married women. With delivery/take-out food frequency, 2 time per week was the highest rate among married women (34.6%) and once per week was the highest among unmarried women (31.2%) respectively. Conclusion: The results of this study indicate food consumption behaviors and trends of Korean women by marital status. This study provides basic data that will be useful for food industries establishing marketing strategies to better meet consumer demands.
