        Purpose: This study was conducted to identify the experiences of families caring for patients with home mechanical ventilation. The question was, “What is the caregiving experience of a family who has a member with home mechanical ventilation?”. Methods: This study was a qualitative study to explore and describe the implications of experiences of families caring through a phenomenological approach. One-on-one in-depth interviews were conducted with family caregivers who worked as full-time for caring for patients with home mechanical ventilation, and the results were analyzed using Colaizzi’s (1978) phenomenological method. Participants’ relationships to patients were 1 spouse, 1 father, and 6 mother. The ages of the participants were between 33 and 59, with an average of 45.1. Results: In this study, family members’ caregiving experience was emerged. Analysis revealed the following themes: Felt burdened but had to accept it; Seized by fear; The weight I must bear alone; Everything is difficult and unfamiliar; Still, my home; and Sorry for the other family members. It was found that caregivers had decided to discharge their loved ones from the hospital out of a sense of duty. Conclusion: The families took care of the patients with responsibility and love. The study results should help with the understanding of a family with a member with home mechanical ventilation and should be used to develop nursing, mediating, and consulting programs for these caregivers

        Background: Push-up are effective exercises for shoulder stability. Previous studies have documented the effects of support plane and hand position and width on muscle activities during a push-up. Objects: This study aimed to investigate the changes in muscle activities in the upper extremity when performing the standard and the knee-flexed push-up with different hand shapes. Methods: A total of twenty-six healthy males participated in this study. Three different hand shapes (finger abduction, finger adduction, and fists) and two types of push-up posture (standard and knee-flexed push-up) were set as the independent variables. Electrograms were used to measure the muscle activity of the upper trapezius (UT), triceps brachii (TB), pectoralis major (PM), and serratus anterior (SA). Each participant performed the randomly assigned push-up to the sound of the metronome. The mixed-effect linear regression model was used to detect the changes in muscle activities after changing the hand shape and push-up posture. Statistical significance was set at α = 0.05. Results: The UT muscle activity was statistically significantly higher when performing push-up with fists than finger abduction (p = 0.035) or finger adduction (p = 0.044). During the standard push-up, the muscle activity in all muscles was that the push-up with fists showed the highest muscle activity compared to the finger abduction (p < 0.01) and finger adduction (p < 0.01). Regardless of the shape of the hand, UT had the lowest muscle activity compared to other muscles (p < 0.001). In contrast, the SA muscle had the highest muscle activity among four muscles during the standard push-up. Conclusion: Based on the results of this study, we suggest hand shape is related to the difficulty level of push-up either in the standard or the knee-flexed push-up, especially in the push-up with fists. In addition, knee push-up can be recommended as shoulder musclestrengthening exercises for individuals with low shoulder muscle strength.

        본 연구의 목적은 대학생의 성지식, 성태도와 성인지 감수성과의 관계를 확인하고, 성인지 감수 성에 미치는 영향을 파악하기 위한 서술적 연구이다. 연구 대상자는 139명의 일반 대학생으로 자가 보고 설문지를 통해 수집된 자료는 기술통계, t-test, ANOVA 및 Schffe test로 분석하였다. 일반 대학생의 성지 식 평균은 38점 만점에 22.73점이었고, 성태도는 5점 만점에 2.92점이었다. 성인지 감수성은 평균 5점 만 점에 2.03점이었다. 연구 결과, 성인지 감수성은 성태도와 양의 상관관계가 있었으며(r=.201, p=.018), 일 반 대학생의 성인지 감수성에 영향을 미치는 요인은 성태도(β=.196, p=.021)로 나타났으며, 설명력은 34.0%였다. 본 연구 결과를 토대로 일반 대학생의 성인지 감수성을 높이기 위해 올바른 성태도를 확립할 수 있는 프로그램 개발이 필요하다.

        본 연구에서는 용매로 침액되었을 시 전반적으로 더 균일한 상전이법 기반 평막 제조 시 주로 사용되는 부직포 지지체의 영향을 분석하였다. 도프용액의 점도가 낮을 경우 용액이 부직포층으로 쉽게 침투하여 불균일한 막이 형성되는 것 을 확인하였으며, 이를 방지하기 위해 부직포층을 유기용매로 침액하는 기법을 도입하였다. 부직포층이 유기 분리막이 생성 되는 것을 확인하였으며, 수투과 및 용매투과율도 향상하는 것을 알 수 있었다. 부직포 침액의 영향은 낮은 점도에서 확연하 게 나타났으며, 고분자용액의 점도가 높은 경우 침액 여부에 관계없이 동일한 성능을 얻을 수 있었다.

        The purpose of this study was to examine the microbiological and physicochemical changes on packaged tofu stored at temperatures of 5, 13, 23, and 30oC, and measure the consumable period from the expiry date to ultimately evaluate the microbiological safety on the extension of the consumable period. From the investigation, the pH value of tofu at each storage temperature (5, 13, and 23oC) showed a slight decrease over the storage period, although there was no significant change. The hardness of packaged tofu decreased more rapidly as temperature and storage time increased and the tofu started to show signs of decomposition at the same time. Analysis on the microbial change of tofu at different storage temperature revealed that the number of general bacteria also increased as the temperature increased. It was further found that packaged tofu takes 25 days at 5oC, 7 days at 13oC, and 1 day at 23oC from the expiry date until the general bacteria count is at least at the early decomposition level which is 10oC log CFU/g. However, no coliform bacteria was detected from tofu after storing at 5, 13 and 23oC. When packaged tofu was stored at 5oC, the L value changed significantly after 26 days, whereas the a and b values showed no significant change during the storage period (P>0.05). When storing tofu at 13oC and 23oC the L value decreased after 8 and 3 days, respectively. However, both a and b values increased (P<0.05).

        목적 : 본 연구는 직업재활에 참여하고 있는 발달장애인의 시간사용을 확인하고, 시간사용에 따른 작업균 형을 제시하고자 한다. 연구방법 : 직업재활 프로그램에 참여하고 있는 발달장애인 106명에게 시간사용과 작업균형을 조사하기 위하여 Occupational Questionnaire를 사용하였다. 자료는 기술통계와 ANOVA을 실시하여 분석하였다. 결과 : 발달장애인은 동일 연령 취업자보다 일상생활의 작업영역에서 일상생활수행 시간이 적고, 여가활동 시간과 수면 시간이 많은 것을 알 수 있었다. 작업유형은 일상활동 유형 5.7%, 여가과다 유형 27.4%, 노동과다 유형 36.8%, 작업균형 유형 30.2%였다. 작업유형과 일상생활의 작업영역은 밀접한 연관을 가 지고 있으며, 작업균형 유형일수록 작업영역에 긍정적인 영향을 미쳤다. 결론 : 직업재활에 참여하고 있는 발달장애인은 시간사용 조율과 각 작업영역간의 작업균형을 맞출 수 있다. 추후, 발달장애인에 대한 접근이나 중재에 작업균형을 고려한 체계화된 지원이 필요할 것으로 사료된다.

        Breakthrough analysis has widely been explored for the dynamic separation of gaseous mixtures in porous materials. In general, breakthrough experiments measure the components of a flowing gas when a gaseous mixture is injected into a column filled with an adsorbent material. In this paper, we report on the design and fabrication of a breakthrough curve measurement device to study the dynamic adsorptive separation of hydrogen isotopologues in porous materials. Using the designed system, an experiment was conducted involving a 1:1 mixture of hydrogen and deuterium passed through a column filled with zeolite 13X (1 g). At room temperature, both hydrogen and deuterium were adsorbed in negligible amounts; however, at a temperature of 77 K, deuterium was preferentially adsorbed over hydrogen. The selectivity was different from that in the existing literature due to the different sample shapes, measurement methods, and column structures, but was at a similar level to that of cryogenic distillation (1.5).
