생물살수여과법을 이용하여 대표적인 휘발성 유기물질인 toluene, styrene과 악취물질인 $H_2S$를 운전조건에 따른 제거 특성에 대해 실험적 고찰을 중심으로 진행하였다. $H_2S$ 제거 특성 고찰을 위한 autotroph과 mixotroph 조건하에서는 $H_2S$ 부하율이 낮은 조건($10g/m^3{\cdot}hr$)에서는 두 조건에서 모두 제거율이 99% 이상을 나타냈다. 부하율이 증가하면서 제거율이 감소하였으며, mixotroph 조건하에서 제거율이 다소 높았다. 방향족 휘발성 유기화합물질인 toluene과 styrene 농도변화에 따른 부하율과 제거용량 관계에서 toluene 부하율이 $40g/m^3{\cdot}hr$ 이하에서는 농도에 관계없이 제거율이 거의 99%를 나타내나 부하율이 증가함에 따라서 제거율은 감소하며 부하율이 증가해도 제거용량이 더 이상 증가하지 않는 최고제거용량을 나타내고 있으며 toluene 농도가 0.2, 0.5과 $1.0g/m^3$일 때 최고제거용량은 각각 40, 45, $60g/m^3{\cdot}hr$으로 나타내고 있다. toluene으로 순응된 살수여과탑에 styrene을 주입하여 순응시킨 후 styrene 제거 실험결과는 toluene 실험결과와 유사한 경향을 나타내었으나 전체적으로 제거효율이 낮게 나타났다. 순환살수액 유량 등의 적정 운전조건은 탑내 미생물의 활성도, 반응기 물리/화학적 특성에 따라 물질전달, 탑내 주입된 공기의 분배, 살수액 통과 경로, 미생물 분포도, 공극율 등에 따라 제거효율이 달라지므로 이를 고려한 적정 운전조건이 결정되어야 한다. Biodegradation of toluene, styrene and hydrogen sulfide as model compounds of volatile organic compounds and odor from waste gas was investigated experimentally in a biotrickling filter. This study focussed on the description of experimental results with regard to operating conditions. The effect of varying $H_2S$ load rate and inlet concentration was investigated under autotropic and mixotropic environmental conditions. The $H_2S$ removal efficiencies of greater than 99% were achieved at $H_2S$ loads below $10g/m^3{\cdot}hr$ for each environment. It was observed that the maximum elimination capacity of mixotrophic filter was achieved a little greater than the one of autotrophic filter. The biofiltration of toluene and styrene in trickling bed was examined under different gas flow rates, load rates, and inlet concentrations. Below $40g/m^3{\cdot}hr$ of toluene loading, the elimination capacity and loading were identical and it was completely destroyed. In high loading of toluene, the biotrickling filter was operated at its maximum elimination capacity. In the inlet concentration of 0.2, 0.5, and $1.0g/m^3$, the maximum elimination capacity of toluene showed 40, 45, and $60g/m^3{\cdot}hr$, respectively. After a short adaptation period, it was demonstrated that the results of styrene in originally toluene adapted bioreactor was similar with the ones of toluene. However, the performance of filer for styrene is generally a little lower than for toluene. The operating conditions (including liquid flow rate etc.) allowing the highest removal efficiency should be determined experimentally for each specific case.

Nursing staffing is of major interest in hospital management, however, no practical method has been developed. The present study proposed a mathematical model based on the patient classification system for nursing staffing optimization. A few characteristic parameters possibly determined experimentally and/or empirically were introduced followed by systematic calculation of the required number of nurses. An essential concept of the model is the unit work load defined as the amount of nursing work performed on single patient per unit time, where the work load is defined as the number of nursing staffs multiplied by the working hours. The unit work load was considered to vary with the patient classification level as well as the working time during a day, both of which were represented by corresponding parameter values. The number of patients for each class and the number of working hours were multiplied to the unit work load, and added up to obtain the total required work load. As the next step, the averaged number of hours that a nurse could provide per day was formulated considering the degree of nursing practice experience into 3 levels. Finally, the appropriate number of nursing staffs was calculated as the total work load divided by the average working hours per nurse. The present technique has a great advantage that the number of nursing staffs to fulfill the required work load is systematically calculated once the characteristic parameters are appropriately determined, leading to instant and fast evaluation. A practical PC program was also developed to apply the present model to nursing practice.

김경옥,박현진,전미선,이은현,김현숙,Kim, Kyoung-Ok,Park, Hyunjin,Chun, Mison,Lee, Eun Hyun,Kim, Hyun-Sook 한국영양학회 2013 Journal of Nutrition and Health Vol.46 No.3

본 연구는 일반인과 유방암 환자를 대상으로 식행동 및 영양정보에 대한 인식조사를 통하여 유방암 예방 및 치료에 대한 식사지침서 자료와 보다 나은 정보 유용성를 마련하고자 수행하였다. 이를 위하여 경기도 수원소재 아주대학교병원 방사선 종양학과 내원자와 건강검진 센터에 방문한 여성 대상자 139명을 조사하였다. 식행동은 식사의 시간, 횟수, 형태 등을 통해 조사하였고, 유방암의 예방 및 치료를 위한 식품 및 영양정보에 대한 인식조사를 살펴 보았다. 연구조사 결과를 요약하면 다음과 같다. 1) 식행동에서 유방암 환자는 정상인에 비하여 규칙적인 시간에 식사를 하고 있으며, 맛 선호도에서는 유방암 환자가 맵고 짠 음식을 선호하는 것으로 나타났다. 2) 식품의 섭취빈도를 살펴본 결과, 유방암 환자는 정상인에 비해 쌀밥, 육류 및 가공품, 생선 및 조개류, 커피, 우유, 치즈의 섭취 빈도는 낮은 반면 잡곡밥, 채소, 해조류, 콩류, 된장 및 청국장, 요거트의 섭취빈도는 높게 나타났다. 3) 특정 식품이 유방암 예방 및 치료에 대한 인식 조사 결과, 정상인과 유방암 환자군간에 유의적 차이를 보인 항목은 쌀밥, 육류, 생선류 및 조개류, 우유 및 유제품이었다. 유의적 차이를 보인 식품군 모두에서 일반인이 유방암 환자에 비하여 긍정적인 인식을 갖고 있는 것으로 조사되었다. 4) 질병에 관련한 영양정보의 출처 선호도 및 신뢰도 조사에서는, 유방암 환자들과 정상인들 모두 언론매체를 통해서 정보를 획득하는 것을 선호하고 있었다. 또한 정상인이 가장 신뢰하는 정보 출처는 언론매체인 반면 유방암 환자는 전문가를 통한 정보출처를 가장 신뢰하고 있는 것으로 나타났다. 본 연구 조사를 종합하면, 유방암 환자는 단백질 주요 급원식품인 육류 및 생선류와 우유 및 유제품 등을 일반인에 비하여 적게 섭취하고 있으며 인식 또한 부정적이다. 그러나 유방암 치료인 약물과 방사선 과정의 빠른 순응도 및 회복을 위해서는 적절한 단백질 섭취가 이루어져야한다. 따라서 영양정보에 대한 인식의 전환과 더불어 실질적인 영양교육 프로그램을 통하여 방사선 치료에 병행되어야 하는 영양소 및 식품을 섭취할 수 있도록 적극적으로 마련되어야 할 것으로 사료된다. 또한, 이를 위하여 유방암 환자군이 가장 신뢰하는 정보획득수단인 전문가 및 임상 영양사들의 역할이 무엇보다 중요한 것으로 생각된다. 전문가 그룹은 유방암 예방 및 치료를 위해서 채소, 과일 뿐만 아니라 단백질 섭취의 중요성 또한 현장 강좌 및 상담 시간에 강조할 필요가 있을 것으로 사료된다. 또한 환자들이 방사선 치료로 인하여 둔화된 미각과 약해진 소화력을 보임을 감안하여 다양한 메뉴 및 조리법 개발에 힘써야 할 것으로 제안하는 바이다. 향후 유방암 예방 및 치료에 대한 정확한 영양정보를 전달하고, 일상생활에서도 올바른 식습관 지침을 구축할 수 있도록 영양 전문가 그룹은 보다 적극적으로 언론매체의 정보전달에 참여해야할 것으로 사료된다. The purposes of this study were 1) to investigate eating behaviors and patterns in breast cancer patients using a newly developed food frequency questionnaire and 2) to examine perception and use of nutritional information about breast cancer treatment among cancer patients treated with radiation therapy. Sixty breast cancer patients (case group) undergoing radiation therapy in Ajou University Hospital, Suwon, South Korea and 79 healthy women (control group) participated in this study. Mean age of subjects in the control group was $46.00{\pm}7.88$ years and BMI was $23.12{\pm}2.85kg/m^2$, and that of the case group was $50.06{\pm}11.64$ years and $22.32{\pm}3.24kg/m^2$. The results of eating behaviors showed several significant differences between control and case groups. Breast cancer patients ate meals on a more regular basis, on time, and more frequently compared to control subjects. In addition, they preferred more salty or spicy and bland food compared to healthy women. According to answers from the food frequency questionnaire, breast cancer patients consumed significantly lower amounts of boiled white rice, meats and processed food, fish and shellfish, coffee, milk, and cheese, whereas they consumed a significantly large amount of boiled multigrain rice, vegetable, seaweeds, soybean and processed food, and yoghurt compared to healthy women. This study also observed the way in which cancer patients and healthy control subjects obtain information about breast cancer treatment and its reliabilities. Results showed that healthy women did not hesitate to obtain information from mass media, while breast cancer patients would obtain nutritional information from specialists rather than mass media. Results of this survey confirmed that breast cancer patients avoided intake of red meat protein, even though they already recognized the importance of dietary protein intake for recuperation and treatment of the disease. These results could be used for future diet and nutrition guidelines for breast cancer patients.

Flammulina velutipes is an edible mushroom and contains a lot of fiber, vitamin $B_1$, $B_2$, niacin and folic acid. This study was conducted to explore the effects of the Flammulina velutipes mushroom on immune cells and immunity. Th1 cytokine productions as $IFN-{\gamma}$, $TNF-{\alpha}$, and IL-2 were measured in an activated macrophage by Flammulina velutipes water extract in seven concentrations (0, 5, 10, 50, 100, 250, 500, and $1,000{\mu}g/mL$). Also, the splenocyte proliferation index was measured at 48 hours after treatment of the Flammulina velutipes water extract in seven concentrations or mitogen, LPS and ConA. The $IFN-{\gamma}$ and $TNF-{\alpha}$ productions were increased by treatment of the Flammulina velutipes water extract. The $TNF-{\alpha}$ production was significantly higher in the $50{\sim}1,000{\mu}g/mL$ Flammulina velutipes water extract treated macrophages. The $IFN-{\gamma}$ production of macrophages treated with the Flammulina velutipes water extract increased significantly in all groups, and the highest $1000{\mu}g/mL$ concentration. The splenocyte proliferation index was enhanced when the $10{\sim}1,000{\mu}g/mL$ Flammulina velutipes water extracts were treated compared to the control. These primary results suggest that Flammulina velutipes may enhance the immune function by activation of the macrophage and spleen cell.

이집트의 콥트 문화에 대한 연구 - 콥트의 언어생활을 중심으로 -

김경옥 ( Kyoung Ok Kim ) 한국중동학회 2014 韓國 中東 學會 論叢 Vol.34 No.2

The Mediterranean Sea connected various cultures throughout West Asia, North Africa, and Southern Europe during the Greco-Roman Empire era. Egypt played a central role in Mediterranean Sea culture. The English name Egypt is derived from the ancient Greek Aigyptos. It is located in the center of world trade, transportation between East and West, tourism and academia. The majority of Christian Egyptians have lived near the banks of the Nile River since the first century. The Egyptian Christians are referred to as Copts and use the Coptic language for their religion and social life. Their language and culture reflect their forward-looking, creative, and flourishing spirit during the Roman and Byzantine Empire eras. They were bilingual people who fluently spoke and wrote the Greek and Coptic languages. They were the first to translate Mark`s Gospels from Greek to Coptic and also translated the Old and New Testaments. Islam arrived in the 7th century and Egypt emerged as a center of politics and culture in the Muslim world. Copts have been bilingual enough to communicate amongst themselves in the Coptic language and with Muslims in the Arabic language. The Coptic language remained the language of the land, but the Arabic language became the formal and official language of social life. Even now, the Coptic language continues to be the liturgical language in the Coptic Church. Yet Copts have to speak Arabic in daily life. Arabic along with Chinese, English, French, Russian, and Spanish are the six official languages in the United Nations. Arabic is only spoken in the Arab world. However, there are two languages that co-existed with Modern Standard Arabic and spoken Arabic. The most popular spoken language in the Arab world is Egyptian Arabic, because Egypt is the leading country among Arab countries in culture. Coptic Christians speak Arabic with each other about their opinions and feelings. Thus Coptic cultures are explained in Arabic. The purpose of this study is to research how Copts have used the Coptic language during the Greco-Roman Empire era, what role the Coptic language played for Copts in Arabic Islam societies historically, and what the prospects for Copts and the Coptic language will be in 21st century.

급속히 변하는 전자, 정보통신 기술에 의한 뉴미디어의 생성과 발전은 우리들에게 보다 다양한 콘텐츠를 양적으로 제공받을 수 있는 기회를 제공하고 있다. 이러한 상황에서 그래픽요소는 양적발달의 콘텐츠를 질적 발달로 향상시키는 수단이 되고 있다. 뉴미디어에 적합한 디자인툴의 생성은 그래픽 작업을 원활하게 해주고 있으나 뉴미디어의 그래픽디자인의 보다 나은 질적 향상을 위해서는 전통적 그래픽디자인의 보다 넓고 깊은 이해를 바탕으로 그래픽 디자인을 수행하여야 할 것이다. Creation and development of new media which are based on the electronics and IT technology, it is rolling out contents for the modern generation, and itprovides us various contents. Graphic design changes the quantity of the contents into the quality of the contents. New media graphic design helps us to use it easy. Above all, we have to understand, learn traditional graphic design for the improvement of new media graphic design. And then we have to use new tools.

Hysteroscopic surgery has become a routine gynecologic procedure. The advantages are associated with more accurate removal of lesion, its short operating time, rapid post-operative recovery and low morbidity. However, there are potentially serious complications which can be occured during and following hysteroscopic surgery. The complications are uterine perforation, fluid overload and electrolyte disturbance due to intravasation and absorption of uterine distention media, hemorrhage and, rarely, gas or air embolism. We experienced pulmonary edema during hysteroscopic surgery in three consecutive patients. Therefore, we report these cases of fluid overload with uterine distention media resulting acute pulmonary edema during hysteroscopic surgery. (Korean J Anesthesiol 2009; 57: 117~22)
