Purpose .This study aims to assess the influence factors on the level of satisfaction with hospital training and to provide basic data for more efficient hospital practice of students' public health administration . Methods . We have conducted a survey on students satisfaction with their hands on practice against 200 students in Busan, Kyeongnam and Kyungbook area, who have completed their practice in public health administration. We have identified the general characteristics of the target respondents, the current training status of the department for the hospital practice and training venue; also analyzed the characteristics composed of the apprentice student's attitude before the practice, satisfaction with the department training program and hospital for practice, as well as their practice at hospital. The general characteristics of the target respondents and clinic practice status at the hospital were measured in percentage and frequency analysis; the average and standard deviations of hospital size were also measured; and the correlations between satisfaction with the department, attitude towards the practice and satisfaction with the hospital were analyzed. Results . Most public health administration students experienced their practice at the hospital after the first semester on the $2^{nd}$year and they have received the foundation training for the practice. The survey allowed multiple responses and the results are as follows: medical terminology 49.5%, medical coordinator 36.7%, Hospital administration 26.5%, Health insurance 17.3%, and medical recording and practice 13.8% respectively. In terms of each individual student's attitude towards the practice at the hospital, the respondents answered as follows: I have completed the obligatory subjects for the practice before the practice 89.5%; I have been fully informed on the hospital for my practice. 74.5%; I responsibly practiced and worked with professionalism and sense of belonging to the hospital as a member of staff 90%; I have actively learned and adopted 95%; My knowledge and skills from the practice was relevant to the theory and practice from my course 83.5%. The findings of satisfaction by size of hospital were in order of a small clinic($3.24{\pm}0.63$), medium sized clinic($3.27{\pm}0.65$), hospital ($3.20{\pm}0.61$), and large sized comprehensive hospital ($2.93{\pm}0.74$). Consequently the satisfaction rate shows no significant difference by size of hospital. In relations between practice attitude and satisfaction with subject, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.04), the matter of a sense of belonging and responsibility at hospital during practice(p=0.33). the matter of active adaptation attitude during practice (p=0.42), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. In relations between practice attitude and satisfaction with the hospital for practice, the matter of acquiring information and fully understanding of the hospital for practice before practice(p=0.01), the matter of a sense of belonging and responsibility at hospital during practice(p=0.04), and the matter of correlations with school curriculum during practice(p=0.00) showed significant results. Conclusion . The most essential subject for the practice in public health administration is medical terminology and there is no significance in satisfaction with the practice by size of hospital. Students were content with the hospital where they can experience as much as possible. Students content with their major show positive attitude towards the practice and so do those content with the hospital. Those with the positive attitude towards the practice show the high correlation of satisfaction with both the major and hospital. As a result, the satisfaction with the major is the significant attribute to the practice in the hospital.

Purpose: This study was designed to search for nursing intervention strategies centering around the meaning structure of the nurse's turnover experience by applying phenomenological methods. Methods: The participants were 6 nurses in small and medium sized hospitals who had experienced at least 1 turnover. Data were collected used MP3 records. The data analysis was done by Giorgi (1985) method. Results: The results were divided into the following categories: 1) Careless decision: wrong decisions, imprudent desire, insufficient patience, unclear future, 2) Inappropriate working environment: irregular working hours, high workload, poor working environment, insufficient understanding of related divisions, lack of opinion collection, low salary, 3) Interpersonal relations problems: discord with colleagues, difficulty in relationships with others, difficulty in daily lives, 4) Lack of specialization: feeling of inertia, lack of role identification, lack of self identification, 5) Inappropriate coping: regret with clinical challenges, difficulty with a new environment, repentance, expectation, relative humility, 6) New self-dignity: expectation, new challenge, relaxing lives, decisions based on future-oriented confidence. Conclusion: The finding of this study will offer profound information on the nurse's turnover experience and provide basic raw materials for improving the quality of nursing performance and contribute to the development of hospital organization.

The Conical 9 well dish (C9 well dish) is characterized by a decreasing cross-sectional area towards the base. This design was hypothesized to enhance embryonic development by emulating the in vivo physical environment through density modulation. Comparative analyses revealed no significant difference in nuclear maturation rates between the C9 well dish and the 5-well dish. Reactive oxygen species (ROS) generation was lower in the C9 well dish compared to the 5-well dish; however, this difference was not statistically significant. On the second day of in vitro culture, the cleavage rate in the C9 well dish was 4.66% higher, although not statistically significant, and the rates of blastocyst development were similar across both dishes. No significant differences were observed in the intracellular levels of glutathione (GSH) and ROS, as well as in the total cell number within the blastocysts between the dish types. The expression of mitogen-related factors, TGFα and IGF-1, in the blastocysts was consistent between the dishes. However, PDGFβ expression was significantly lower in the C9 well dish compared to the 35 mm petri dish. Similarly, the expression of the apoptosis factor Bax/Bcl2l2 showed no significant differences between the two dishes. Despite the marked difference in PDGFβ expression, its impact on blastocyst formation appeared negligible. The study also confirmed the feasibility of culturing a small number of oocytes per donor, collected via Ovum Pick-Up (OPU), with reduced volumes of culture medium and mineral oil, thus offering economic advantages. In conclusion, the present study indicates that the C9 well dish is effective for in vitro development of a small quantity of oocytes and embryos, presenting it as a viable alternative to traditional cell culture dishes.

Background: Patients on dialysis undergoing surgery belong to a high-risk group. Only a few studies have evaluated the outcome of major thoracic surgical procedures in dialysis patients. We evaluated the outcomes of pulmonary resection for non-small cell lung cancer (NSCLC) in patients on hemodialysis (HD). Methods: Between 2008 and 2013, seven patients on HD underwent pulmonary resection for NSCLC at our institution. We retrospectively reviewed their surgical outcomes and prognoses. Results: The median duration of HD before surgery was 55.0 months. Five patients underwent lobectomy and two patients underwent wedge resection. Postoperative morbidity occurred in three patients, including pulmonary edema combined with pneumonia, cerebral infarction, and delirium. There were no instances of in-hospital mortality, although one patient died of intracranial bleeding 15 days after discharge. During follow-up, three patients (one patient with pathologic stage IIB NSCLC and two patients with pathologic stage IIIA NSCLC) experienced recurrence and died as a result of the progression of the cancer, while the remaining three patients (with pathologic stage I NSCLC) are alive with no evidence of disease. Conclusion: Surgery for NSCLC in HD patients can be performed with acceptable perioperative morbidity. Good medium-term survival in patients with pathologic stage I NSCLC can also be expected. Pulmonary resection seems to be the proper treatment option for dialysis patients with stage I NSCLC.

사람의 내피세포는 동물내피세포에 비해 배양증식이 어려운 것으로 알려져 있어 이를 효율적으로 배양증식 시키기 위해서 배양액에 내피세포성장인자를 헤파린과 함께 첨가하는 방법이 많이 사용되어 오고 있다. 한편 최근에는 세포내 cyclic adenosine monophosphate(cAMP)을 증가시키는 물질들인 콜레라독소와 아이소부틸메틸산틴(isobutlmethylxanthine, IBMX)을 세포배양액에 첨가하여 내피세포 증식을 향상시킨 실험결과가 보고된바 있다. 이런 연구결과들을 토대로 할때 내피세포 배양액에 내피세포성장인자 및 헤파린과 함께 cAMP 증가물질을 같이 첨가하여 주면 내피세포의 성장증식을 보다 향상시킬수 있을 것이라는 가설이 가능할 것이다. 본 실험에서는 이와같은 가설을 검증하기 위해 사람의 대망 미세혈관(omental microvessel)으로부터 내피세포를 분리배양한뒤 내피세포성장인자 및 헤파린과 cAMP 증가물질들의 첨가가 내피세포의 증식에 미치는 영향을 분석하고, 궁극적으로는 사람 내피세포의 최적 배양증식 조건을 확립하고자 하였다. 실험 결과 사람의 대망 미세조직에서 내피세포를 분리하여 이를 효과적으로 배양증식하기 위해서는 내피세포성장인자와 헤파린을 첨가한 배지를 사용하거나, 또는 내피세포성장인자를 사용하지 않는 경우 콜레라독소와 IBMX를 병합 첨가하는 것이 좋은 것으로 관찰되었으며, 내피세포성장인자와 콜레라독소 및 IBMX를 동시에 병합 첨가하는 것은 효과가 없는 것으로 밝혀졌다.

Background: Subscapularis tendon insertion at the first facet has separate layers (deep and superficial). The purpose of this study is to evaluate postoperative clinical outcomes and radiological healing according to each layer of detachment in the first facet involving subscapularis tendon tear. Methods: Eighty-three patients who underwent arthroscopic repair due to First facet involving the scapularis tendon tear accompanying small to medium sized posterosuperior cuff tear were classified into three groups (group A: deep layer partial detachment, group B: deep layer complete detachment, but no superficial layer detachment, and group C: deep layer and superficial layer complete detachment). Subscapularis tendon healing was evaluated using computed tomography arthrogram and clinical result was evaluated using American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score and University of California Los Angeles (UCLA) shoulder score. Results: Retear rate of the subscapularis tendon was 2.2%, 18.2%, and 33.3% in group A, group B, and group C, respectively. These rates showed statistically significant difference among the three groups, which were classified by deep and superficial layer detachment in the first facet (p=0.003). Group A showed significant difference in subscapularis tendon healing compared with group B and group C (p=0.018 and p<0.001, respectively), but there was no statistical difference between group B and group C (p=0.292). Regarding clinical outcomes, there was no significant difference among three groups in ASES and UCLA score at final follow-up (p=0.070 and p=0.106, respectively). Conclusions: Complete detachment of deep layer may be related with retear occurrence regardless with detachment of superficial layer, but clinical outcome may not be related with each layer detachment in the first facet involving subscapularis tendon tear.

This study was designed to investigate the number of the growing and mature follicles in each stage of estrus cycle in mature rats. Eighteen mature rats(Sprague-Dawley, initially 190~230gm) were randomly alloted into 4 groups(proestrus, estrus, metestrus, and diestrus) according to estrus cycles. The uteri and ovaries of rats were collected and then alternative sections of paraffin embedding ovaries were stained with H-E. Numbers of large, middle and small follicles or only large and middle follicles from secondary and tertiary follicles were investigated by LM photography of preparations. Small follicles were defined as secondary follicles with 2~5 cell layers of granulosa cells surrounding the oocyte, and middle follicles were defined as secondary follicles with more than 5 cell layers or with early signs of antral cavity or with more than one small cleft on either side of the oocytes and large follicles were defined as tertiary follicles with a single medium or large antral cavity. The number of follicles in a pair ovary per rat was appeared to be ranged from 207 to 370 and the mean number of these follicles was $270.4{\pm}52.6$ and the mean number of follicles per ovary was $134.9{\pm}32.0$. The mean number of large, middle and small follicles per ovary was appeared to be $16.4{\pm}4.4$($12.2{\pm}3.3%$), $36.2{\pm}8.6$($26.8{\pm}6.4%$), and $82.7{\pm}24.0$($61.3{\pm}17.8%$), respectively. The mean number of large and middle follicles in each stage group of estrus cycle was appeared to be $17.8{\pm}2.1$ and $38.3{\pm}7.4$ at proestrus stage group, $15.7{\pm}5.2$ and $38.0{\pm}10.0$ at estrus stage group, $16.5{\pm}3.5$ and $33.8{\pm}7.0$ at metestrus stage group, $16.7{\pm}5.8$ and $29.7{\pm}5.5$ at diestrus group, respectively. In histological findings of large follicles during each estrus cycle, the large follicles in proestrus group contain single small antrum, thick granulosa cell layers, and were $300{\sim}500{\mu}m$ in diameter and were growing follicles with PCNA-positive cells in the granulosa cell layers, and other luteinizing follicles of proestrus cycle stage were decreased in size and were thicker in wall thickness and more luteinized than those in metestrus and diestrus stage groups. The large follicles in estrus stage group contain thick granulosa cell layers and nonprominent cumulus-oocyte complexes in antrum, and were $400{\sim}700{\mu}m$ in diameter and were growing follicles with PCNA-positive cells in the granulosa cell layers. The large follicles in metestrus and diestrus stage groups contain enlarged antrums, thinner layers of walls and prominent cumulus-oocyte complexes, and were $700-950{\mu}m$ in diameter, and were nongrowing follicles without PCNA-positive cells or another large follicles contain cells with dark stainability and distinct boundary.

It has been 2 years since the implementation of the separation policy of drug prescription and dispensing. This study analyzes the changes in community pharmacy operation after the implementation of the policy. The main purposes of the analysis are to determine whether the changes in community pharmacy operation have occurred and to evaluate that the changes are consistent with the intention of the policy, if the changes actually have occurred. For the study a survey on 961 pharmacies chosen by stratified sampling method has been performed. Of the 961 sample pharmacies, 438 pharmacies were responded resulting 45.6% response rate. The sample pharmacies are classified by the location that the pharmacy are operating: the pharmacies around large size hospitals, the pharmacies around clinics or medium to small size hospitals and the pharmacies with no hospitals or clinics around. Based on the classification, the number of pharmacies, number of prescriptions processed, the personnel structure, the changes in facility, and other operational characteristics are compared. The results showed that the pharmacies were tended to concentrate around hospitals and clinic since the implementation of the policy. The number of pharmacists per pharmacy was increased, the size of pharmacy was increased and the facilities were improved to accomodate the requirements of the policy. The work hours a pharmacist spent on dispensing drug have increased almost twice, however, there was no corresponding increase in the time spent on patient education and medication history management, indicating a problem in the provision of quality pharmaceutical services. Based on the results, suggestions to minimize the negative effects of the policy are provided.

본 연구는 간호사와 간호조무사의 동기를 제고하고 효과적인 간호서비스 제공을 촉진하기 위해 의사와의 관계에서 간호사와 간호조무사가 느끼는 직무 및 대인관계의 갈등 정도와 원인을 파악하고자 수행하였다. 이를 위해 중소규모 병원에 근무하고 있는 간호사와 간호조무사 271명을 대상으로 직무 및 인간관계 갈등 정도, 원활한 의사소통 여부, 갈등 원인과 해결방법 등에 대해 설문조사를 실시하고 분석하였다. 분석 결과 의사와의 관계에서 간호사와 간호조무사가 느끼는 갈등의 내용과 정도는 대체로 비슷하였으나 의사와 간호직의 역할이 중복되거나 모호한 부분이 있다고 느낀다는 점에서는 간호사가 간호조무사 보다 더 많은 스트레스를 받고 있었다. 의사와 갈등이 발생했을 때 해결하는 방법으로는 간호사와 간호조무사 모두 적당히 피한다는 의견이 가장 많았다. 그 다음의 갈등해결 방법은 간호사와 간호조무사 간에 차이가 있었는데 간호사는 상대방에게 나의 의견을 따르도록 함, 노조를 통해 해결 등의 순이었고, 간호조무사는 상사에게 해결하도록 함, 서로 조금씩 양보해서 타협함 등의 순이었다.
