Background: The purpose of this study is to assess the effectiveness of family support on the quality of life in patients admitted to the hospice facility at Saemmul Hospice. Method: The subjects of this study were 152 terminal cancer patients that were admitted to the hospice facility at Saemmul hospice between January 2002 and February 2003. Their each quality of life were assessed at admission, one, three, five and seven weeks at Saemmul Hospice using a questionnaire prepared by the Saemmul hospice and were anlalyzed by means of T-test. Result: There was no difference in the quality of life score between patients with family support and patients without family support in terms of physical, psychosocial, and spiritual aspects in the admission. There was no difference in the quality of life score between the patients with frequent family member's visit(>=8) and less frequent family visit(<=7), and between the patients whose family members stayed at the facility for 24hrs and the patients without staying family members. There was no difference in the quality of life score between the patients in low-middle and low-high class among 9 classes of familial economic status(high-high, high-middle, high-low, middle-high, middle-middle, middle-low, low-high, low-middle, low-low). There was no difference in the quality of life score between the patients whose familial religion were Christianity and the patients with other religions. After 1, 3, 5, 7 weeks assessment, the scores in the physical, psychosocial, spiritual aspect of quality of life were increased. Conclusion: The results suggest that family support is important to improve the quality of life in hospice patients and hospice care team is needed to replace 24 hours of family care. There is a urgent need of trained hospice care teams, so training programs for physicians, nurses, clergies, social workers, and volunteers are necessary.

The hospice activities in Korea have still stood in the premature stage, although the contemporary hospice program, which professionally accommodates terminally ill patients, appeared in the history 35 years ago. Especially, the availability of the facility hospice is not only poor in number, but also lack of a guideline for the conduct of the facility. Saemmul Hospice has keenly felt the necessity of more facility hospices and has interchanged experiences and informations with people interested in hospice. However, the number of facilities has fallen short of one's expectations, and many problems have been revealed in order to maintain the operation. This paper was written in order to improve these atmospheres and to help more terminally ill cancer patients properly. This paper clarifies in detail the principle of management, the method of practice in each departments of Saemmul Hospice, expected effects and supplemental items. We try to provide concrete and practical informations and to help extensively for all peoples who are to begin or currently working. 1.Facility: It secures, maintain, and manage the hospice environment for all around care of patients effectively. 2.Education and Volunteer: It trains and manages hospice volunteers devoted to hospice. 3.Financial: It manages donation by healthy soul with an effective method. 4.Administration and Organization: It executes the administration efficiently and constitutes the organization to operate. 5.Medical and Nursing: It offers the maximum professional supports to a hospital. 6.Medicine and alternative medicine: It improves the quality of life of patients by medical and pharmaceutical approach and by other possible methods available. 7.Nutrition: It helps patients to have diets in accord with the order of the creation. 8.Belief: It offers spiritual care which allows the profound relationship with God. 9. Funeral ceremonies: Funeral ceremonies may heal grieves of families faced with their deaths. 10. Bereaved families: It supports the families after the deaths of patients. 11.Reception and consultation: It seeks to help the patients who meet the purposes for which Saemmul Hospice is established. 12.Publication: It allows publicity activities for Saemmul Hospice. Facility hospice programs are able to overcome the disadvantages that the other type of the hospice possess, like as the economic burdens of the families, and the patients' losses of comforts of home after being transferred to a hospital. Facility hospice can provide home atmosphere with professional manpower and facilities like hospital to the patients. Therefore, it can also improve patients' qualities of life and make them comfortable death. We anticipate that the hospice program in Korea would be more active to let more people be indebted to maintain the nobel human dignity and to cross beautifully in the most painful process of dying in the journey of their lives.

The TiN thin films were deposited by ALE(atomic layer epitaxy) on (100) silicon substrate. The TiN thin films were characterized by means of XRD, 4-point probe, AFM, AES and SEM. TEMAT(terakis(ethyl methy lamino)titanium) and $NH_3$ were injected into the reactor in sequence of TEMAT-$N_2-NH_3-N_2$ to ensure a saturated surface reaction. As a result, the depostion rate of the TiN film was controlled by self-limiting growth mechanism at temperature range form 150 to 220 $^{\circ}C$. Deposited TiN films, all of which show amorphous structure, had a fixed deposition rate of 4.5 ${\AA}$/cycle. The resistivity of 210 ~ 230 ${\mu}{\Omega}{\cdot}$cm and the surface r.m.s. roughness of 7.9 ~ 9.3 ${\AA}$ were measured. When TiN film of 2000 ${\AA}$ were deposited, a excellent step coverage were observed in a trench structure of 0.43${\mu}m$ contacts with 6:1 aspect ratio.

As a nursing practice involves nurses'actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives. Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal); excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, accountability and commitment(4 theories of nursing ethics); human respect, partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences, positive perspectives(4 theories of nurse), role of intervention, rewarding, peer relationship(3 theories of situations). The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore, it is recommended to review the theories-in-use in order to find any discrepancies between the espoused theories and the reality of nursing actions.

The effects of operating temperature and electrode gap distance on electricity generation were investigated in two-chamber type MFCs. Voltages across the external resistor $(100\;{\Omega})$ were enhanced approximately 1.4 times by the increase of operating temperature from $30^{\circ}C$ to $34^{\circ}C$. The open circuit voltages (OCVs) were increased by the increase of temperature and the maximum power of MFC was obtained at higher current condition by increasing temperature and reducing electrode gap distance. The maximum power densities were enhanced from 1.9 to 2.4 times according to the experimented electrode gap distances by increasing temperature of $4^{\circ}C$. The electricity generation was increased with the decrease of electrode gap distance. The effects of operating temperature and electrode gap distance were closely connected with the internal resistance of MFC system. That is, the increase of temperature and decrease of electrode gap distance reduced the internal resistance of MFC, resulting in the enhancement of electricity generation of MFC.

To evaluate the diagnostic accuracy of the measurement of free thyroxine (FT4) by radioimmunoassay, we measured free $T_4\;and\;T_4,\;T_3,\;T_3RU$, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1. In 19 cases of overt hyperthyroidism, $T_3,\;free\;T_4$ and FTI, $T_4/TBG$ ratio reflect hyperfunction in all cases. $T_4$ is increased in 94% (18/19) and TBG and TSH are decreased in 79% (15/19). 2. In 8 patients with overt hypothyroidism, TSH is increased in all cases and free $T_4$ and FTI is decreased in all cases. $T_4$ is decreased in 87.5% (7/8), $T_3$ is decreased in 75% (6/8) and $T_4/TBG$ ratio is decreased in 62.5% (5/8). 3. In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, $T_4,\;free\;T_4$, FTI and TSH are in the normal range in all cases and $T_3$ is normal in 60% (3/5) and slightly increased in 40% (2/5). 4. In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free $T_4$ and FTI are decreased in all cases, but $T_4\;and\;T_3,\;T_4/TBG$ ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free $T_4$ or FTI are recommended as optimal thyroid function test. 5. In normal pregnancy, free $T_4$, FTI and $T_4/TBG$ ratio reflect normal function, but the other parameters revealed unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6. The coefficients of correlation between free $T_4$ and FTI were 0.862 (p<0.001) and 0.685 (p<0.001) between free $T_4\;and\;T_4/TBG$ ratio. In most patients, diagnostic value of free $T_4$ was comparable and even superior to FTI, so free $T_4$ measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyrodism or with $T_3$ for the diagnosis of hyperthyroidism.

본 논문에서는 30% 내외의 평균반사율을 가지는 다결정 실리콘 태양전지의 입사광 손실을 최소화하여 광전변환효율 극대화를 구현하기 위해서 SF6/O2 혼합가스를 이용한 RIE 표면 texturing 공정을 수행하였다. 현재 다결정 실리콘 태양전지는 다양한 방향의 grain을 가지기 때문에 단결정 실리콘에 적용되는 습식 식각 방식이 다결정 실리콘 표면 texturing에 적절하지 않은 것으로 알려져 있다. 이를 개선하기 위해서 이방성 식각 특성을 가지는 다양한 texturing 방법이 시도되고 있다. 대표적으로 기계적인 방식의 V-grooving, 레이저 grooving, 플라즈마 건식식각을 이용한 texturing 및 산 용액을 이용한 texturing 등의 연구가 보고되고 있다. 그 중에서 플라즈마 건식식각 방식의 하나인 RIE를 이용한 표면 texturing 공정이 간단한 공정과 산업계 응용의 용이성 때문에 활발히 연구되어 왔다. 특히 Sandia group과 일본 Kyocera사의 연구 결과에서는 그 가능성을 입증하고 있다. 본 연구에서는 공정의 단순화와 안전한 공정을 위해서 SF6/O2 혼합 가스를 이용하여 마스크 패턴 공정없이 RIE texturing 공정을 수행하였으며, RIE-textured 다결정 실리콘에 대해서 태양전지를 제작하여 표면 texturing이 광전변환효율에 미치는 영향에 대해서 분석하였다. 그 결과 SF6/O2 혼합 가스를 이용한 RIE texturing은 다결정 실리콘 표면에 주로 needle 구조를 형성하는 것을 확인하였다. 각 texturing 조건별 반사율의 차이는 needle 구조의 조밀도와 관련되는 것을 알 수 있었으며, 동일 공정 parameter 상에서 식각 시간 1, 2, 3, 4, 5분 기준 시간에 따른 표면 구조 분석 결과 seed 가 형성되고 그에 따라서 needle 형태로 식각되는 과정을 관찰하였다. 반사율은 분당 약 4%씩 낮아져 5분 식각 후 14.45% 까지 낮아졌으며, 표면 구조에서 폭은 약 30 nm로 모두 일정하며, 길이가 약 20, 30, 50, 80, 100 nm으로 증가되었다. 이 결과로 보아 seed로부터 needle 구조가 심화되어가는 것을 알 수 있었다. 시간에 따른 RIE texturing 후 제작된 태양전지는 효율이 1분 식각 기준 15.92%에서 약 0.35% 씩 낮아져 5분 식각 후 14.4%로 낮아졌다. Voc 는 texturing 시간에 관계없이 일정하며 Isc가 점점 감소되는 것으로 확인되었다. EQE 결과도 이와 동일하게 RIE texturing 시간이 길어질수록 전체 파장 범위에서 일정하게 낮아지는 것이 관찰되었다. Electroluminescence(EL) 이미지 결과 texturing 시간이 길어진 태양전지일수록 점점 어두운 이미지가 나타나 5분 식각의 경우 가장 어두운 결과를 나타내었다. 이런 결과는 한 가지 이유보다는 복합적인 문제로 예상되는데 궁극적으로는 RIE 공정 후 표면에 쌓인 charged particle들이 trap 준위를 형성하여 효율 및 공정상에 영향을 미친 것으로 보이며, 특히 잔류 O기가 불균일한 산화막을 형성하는 것으로 예상된다. 또한 EL 분석 결과를 볼 때 RIE texturing 공정이 길어질수록 불안정한 pn-junction을 형성하는 것을 확인하였으며, emitter 층 형성 후 PSG (phosphorous silica glass) 공정에서 needle의 상부 구조가 무너지면서 면저항이 증가된 결과로 분석된다. PSG 제거 후 측정된 면저항의 경우 3분 texturing 샘플부터 면저항이 약 4${\Omega}/sq$ 정도 증가됨을 확인하였다.

Ionic polymer metal composites (IPMC) are soft polymeric smart materials having large displacement at low voltage in air and water. The polymeric electrolyte actuator consists of a thin and porous membrane and metal electrodes plated on both faces, in impregnation electro-plating method. The response and actuation of actuator are governed. Among many factors governing the activation and response of IPMC actuator, the surface electrode plays an important role. In this study, the well-designed modification of electrode surface was carried out in order to improve the chemical stability well as electromechanical characteristics of the IPMC actuator. We employed Ion Beam Assisted Deposition (IBAD) method to prepare the topologically homogeneous thin surface electrode. After roughing the surface of Nafion membrane in order to get a larger surface area, the IPMC was prepared by impregnation for electro-plating and re- coating on the surface through traditional chemical deposition, followed by an additional surface treatment with high conductive metals with IBAD. It was observed that our IPMC specimen shows the enhanced surface electrical properties as well as the improved actuation and response characteristics under applied electric field.

This research paper is of a 'mixed method' research design: the quantitative analysis covering general data and the current condition of male nurses, the qualitative analysis being used on interview transcript data. The research subjects are 19 male nurses who work at a hospital and 29 female nurses who are doing Masters degrees in "J" province of the Republic of Korea. The data collection period was March 25 to April 1, 2015. The quantitative data was analyzed with SPSS WIN 19.0 software while the qualitative data was analyzed according to the 'contents analysis' method. The results show that the satisfaction of male participants in their profession is higher than average. The item 'growth as a professional' was rated highest as a satisfying aspect of working as a nurse. A difference was observed in the points of view of male and female participants, however, both male and female nurses have a positive view of male nurses which over comes traditional stereotypes. These results will be used to establish a positive image of nurses across genders.
