Background and Objectives: In cochlear implant (CI) surgery, the results and causes of revision and reimplantation may guide surgeons in establishing surgical protocols for revision surgery with safe audiological outcomes. The aim of this study was to review our experience in terms of etiology, surgical strategy, and hearing outcomes in pediatric patients who underwent CI removal and reimplantation. Subjects and Methods: All patients received implants of the same brand. Pre and postoperative Categories of Auditory Performance score and aided free-field pure tone audiometry thresholds were noted. In vivo integrity tests were performed for each patient and the results of ex vivo tests of each implant were obtained from manufacturer. Results: A total of 149 CIs were placed in 121 patients aged <18 years. The revision rate in children was 6.7% (10/121 children). Six patients had a history of head injury leading to a hard failure. The causes of reimplantation in others were soft failure (n=1), electrode migration (n=1), infection (n=1), and other (n=1). All patients showed better or similar postreimplantation audiological performance compared with pre-reimplantation results. Conclusions: It is very important to provide a safe school and home environment and educate the family for reducing reimplantation due to trauma. Especially for active children, psychiatric consultation should be continued postoperatively.

Purpose: We aimed to investigate the objective cutoff values of unstimulated flow rates (UFR) and stimulated salivary flow rates (SFR) in patients with xerostomia and to present an optimal machine learning model with a classification and regression tree (CART) for all ages. Materials and Methods: A total of 829 patients with oral diseases were enrolled (591 females; mean age, 59.29±16.40 years; 8~95 years old), 199 patients with xerostomia and 630 patients without xerostomia. Salivary and clinical characteristics were collected and analyzed. Result: Patients with xerostomia had significantly lower levels of UFR (0.29±0.22 vs. 0.41±0.24 ml/min) and SFR (1.12±0.55 vs. 1.39±0.94 ml/min) (P<0.001), respectively, compared to those with non-xerostomia. The presence of xerostomia had a significantly negative correlation with UFR (r=-0.603, P=0.002) and SFR (r=-0.301, P=0.017). In the diagnosis of xerostomia based on the CART algorithm, the presence of stomatitis, candidiasis, halitosis, psychiatric disorder, and hyperlipidemia were significant predictors for xerostomia, and the cutoff ranges for xerostomia for UFR and SFR were 0.03~0.18 ml/min and 0.85~1.6 ml/min, respectively. Conclusion: Xerostomia was correlated with decreases in UFR and SFR, and their cutoff values varied depending on the patient's underlying oral and systemic conditions.

Purpose: This study aimed to investigate the effects of restorative family circles (RFCs) on empowerment and family support for people with mental illness, and the belief system and caring experience of their families. Methods: This study used a quasi-experiment with a non-equivalent control group pretest-posttest non-synchronized design. Ninety-two dyads of patient-family caregivers were recruited using convenience sampling and assigned to the experimental and control groups. The subjects of the experimental group participated in RFCs consisting of eight 90-minute sessions. Data were collected at three different times (pretest, posttest, follow-up test) and analyzed for the effects of RFC using the 𝑥² test, Fisher's exact test, Mann-Whitney U test for homogeneity between groups, and generalized estimating equation models. Results: The findings of this study showed that there were significant differences in the family support for people with mental illness between the pretest and follow-up test, and also in the belief system and caring experience of the family between the pretest and posttest. Conclusion: This study revealed that family interventions based on restorative justice emphasizing community-driven conflict management could be used in psychiatric mental health nursing care for fostering a cohesive family relationship.

Purpose: Methamphetamine is an ongoing illegal drug problem worldwide, and its use in South Korea has spread over the last few years. In this study, a clinical review of patients who visited emergency medical centers with positive methamphetamine tests was conducted. Methods: Patients underwent methamphetamine screening based on physician suspicion over a period of 13 years. Their patient characteristics, clinical features, and drug administration properties were described. Results: A total of 297 patients were included, with 19 positive methamphetamine results. Patient age ranged from 21 to 84, with a mean of 37.52. Additionally, 13 were male and 6 were female. The mean BP, PR, RR were 131/82 mmHg, 94/min, 20/min. Saturation levels were all over 95%. Five patients had a psychiatric history. Patient showed varied symptoms ranging from mental changes to chest discomfort. In addition, seven showed abnormal electrocardiography findings and one showed elevated cardiac enzyme levels. Other laboratory results revealed no significantly abnormal results. Six patients also suffered from related trauma. The majority of patients consumed the methamphetamine orally, with unknown motivation at unknown locations. Most were transported by 119 and six patients co-ingested other drugs. Conclusion: Patients who showed positive results to a methamphetamine screening test in Korea visited the emergency medical center mostly by 119 and were unaware of or reluctant to reveal the fact that they had ingested methamphetamine. Emergency physicians should be more aware of the possibility that a patient may have consumed methamphetamine.

Background : It is very common in Korea to take care of non-acute patients in an acute setting, due to the lack of long-term facilities. Long term hospitalization increase medical expenses and decreases the bed utilization, which can affect the urgent and emergent admissions, and eventually jeopardize the hospital financially. In this study, strategies for effective transfers to the lower levels of care, and to decrease the length of stay were presented by surveying and analyzing the patient's knowledge of the transfer needs, and the willingness to transfer those whose hospital length of stay was more than 30days. Method : The survey is subject to a group of 251 patients who have been hospitalized over 30 days in a general hospital in Seoul. Excluding those that were in the Intensive Care Unit and psychiatric ward, 214 in-patients were used as participants. They were surveyed from April 9, 2002 to April 17, 2002. One hundred and thirty seven out of 214 were responded which made the response rate 64%. Data were analyzed by SAS and SPSS. Result : Multi-variable Logistic Regression Analysis showed a significant effect in medical expenses, knowledge of referral system and the information of the receiving hospital. The financial burden in medical expenses made the patient 10.7 times more willing to be transferred, knowledge of the referral system made them 5 times more willing to be transferred, and the information of receiving hospital makes 6.5 times more willing to be transferred. Reasons for willing to be transferred to a lower level of care were the phase of physical therapy, the distance from home, the attending physician's advice and being unable to be treated as an out patient. Reasons for refusing to be transferred were the following. The attending physician's competency, not being ready to be discharged, not trusting the receiving hospital's competency due to the lack of information, or never hearing about the referring system by the attending physician. Conclusion : Based on this, strategies for the effective transfer to the lower levels of care were suggested. It is desirable for the attending physician to be actively involved by making an effort to explain the transfer need, and referring to the Healthcare Coordinating Center, which can help the patient make the right decision. Nationwide networking for the referral system is the another key factor that may need to be suggested as an alternative to decrease the medical expenses. Collaborating with the Home Health Agency for the early discharge planning and the Social Service Department for financial aid are also needed. It is recommended that the hospital should expedite the transfer process by prioritizing the cost and the information as medical expenses, knowledge of referring system and the information of the receiving hospital, are the most important factors to the willingness to transfer to a lower level of care.

A cost analysis for hospitalized patients was carried out based upon Patient Classification System(PCS) in order to determine an appropriate nursing fee. The data were collected from 21 nursing units of three teaching hospitals from April 1 to June 30, 1989. first, all of the 22,056 inpatients were classified into mildly ill(Class Ⅰ), moderately ill(Class Ⅱ), acutely ill(Class Ⅲ), and critically ill(Class Ⅳ) by the PCS which had been carefully developed to be suitable for the Korean nursing units. Second. PCS cost accounting was applied to the above data. The distribution of inpatients, nursing costs, and nursing productivity were as follows : 1) Patient distribution ranged from 45% to class Ⅰ, 36% to class Ⅱ, 15% to class Ⅲ, and 4% to class Ⅳ, the proportion of class Ⅳ in ‘H’ Hospital was greater than that of the other two hospitals. 2) The proportion of Class Ⅲ and Ⅳ in the medical nursing units was greater than that of surgical nursing units. 3) The number of inpatients was greatest on Tuesdays, and least on Sundays. 4) The average nursing cost per hour was W 3,164 for ‘S’ hospital, W 3,511 for ‘H’ hospital and W 4,824 for ‘K’ hospital. The average nursing cost per patient per day was W 14,126 for ‘S’ Hospital, W 15,842 for ‘H’ hospital and W 21,525 for ‘K’ hospital. 5) The average nursing cost calculated by the PCS was W 13,232 for class Ⅰ, W 18,478 for class Ⅱ, W 23,000 for class Ⅲ, and W 25,469 for class Ⅳ. 6) The average nursing cost for the medical and surgical nursing units was W 13,180 and W 13,303 respetively for class Ⅰ, W 18,248 and W 18,707 for class Ⅱ, W 22,303 and W 23,696 for class Ⅲ, and W 24,331 and W 26,606 for class Ⅳ. 7) The nursing costs were composed of 85% for wages and fringe benefits, 3% for material supplies and 12% for overhead. The proportion of wages and fringe benefits among the three Hospitals ranged from 75%, 92% and 98% for the ‘S’, ‘H’, ‘K’ hospitals respectively These findings explain why the average nursing cost of ‘K’ hospital was higher than the others. 8) According to a multi- regression analysis, wages and fringe benefits, material supplies, and overhead had an equal influence on determining the nursing cost while the nursing hours had less influence. 9) The productivity of the medical nursing units were higher than the surgical nursing units, productivity of the D(TS) - nursing units was the lowest while the K(Med) - nursing unit was the highest in 'S' hospital. In ‘H’ hospital, productivity was related to the number of inpatients rather than to the characteristics of the nursing units. The ‘K’ hospital showed the same trend as ‘S’ hospital, that the productivity of the medical nursing unit was higher than the surgical nursing unit. The productivity of ‘S’ hospital was evaluated the highest followed by ‘H’ hospital and ‘K’ hospital. Future research on nursing costs should be extended to the other special nursing areas such as pediatric and psychiatric nursing units, and to ICU or operating rooms. Further, the PCS tool should be carefully evaluated for its appropriateness to all levels of institutions(primary, secondary, tertiary). This study took account only of the quantity of nursing services when developing the PCS tool for evaluating the productivity of nursing units. Future research should also consider the quality of nursing services including the appropriateness of nursing activities.

정신과 영역의 환자를 위해 간호원의 역활을 필요로 한 이래 여러 가지 간호의 개념으로 간호원의 역할이 변화되어오고 있다. 정신과 환자의 안전만이 가장 큰 치료의 중심일 때는 병동열쇠의 위엄에 곁따라 보호관리에만 치중해 왔으며 정신의학에서 약물요법, 전기요법의 치료과정이 생기면서 간호원의 역할 변화 및 지식의 요구를 필요로 하게 되었으며, 환경과 개인의 밀접한 관계를 중시해오면서 치료적 환경속으로 환자의 인간적 치료가 강조되었을 때 의사소통과 대인관계의 인적 환경으로써 또한 간호원의 역활이 중요시 되어왔다. 이런 관점에서 치료적 환경에 대한 정확한 이해는 간호행위과정의 불완전을 제거하며 보다 활발한 정신과 환자간호에 기여하는 일 일 것이다. DR. Bartom은 병실 환경이 비생산적이고 비 치료적일때 성격의 변화는 물론 행동적 특성의 변화까지 가져올 수 있다고 말했다. 즉 무감동적이고, 무조건적 순종이 있으며 솔선하여 행하는 행위가 줄고 장래 계획에 대한 자극이 줄어들고 될대로 되어 가는 상태 그 자체에 머물러 있어 인간의 특징적 의미와 가치를 상실하게 된다는 것이다. 정신과 병실은 잠정적 체류지로 보아야 하겠고 이 체류지에서의 영향이 환자에게 보다 유익하게 끼칠려면 간호원이 지속적으로 치료적 분위기를 유지해야 할 것이다. 치료적 입장으로서의 간호의 활동 초점은 대인관계에서 환자의 의식수준과 자아관련 수준에서의 취급이 무의식 수준에서의 탐구조사보다 바람직하다. 치료적 가치로써 치료적 환경의 이론적 근거를 DR. Sullivan 은 인간의 상호관련 문제에 두고 있다. 즉 상호작용이 존재하는 환경은 어떠한 곳이든 성격에 영향이 있고 이 성격은 대인관계의 복잡성으로부터 결코 떨어질 수 없다는 얘기다. 자아구성 또한 환경의 영향을 받는데 Cumming은 병동환경과 자아구성 재동기간에 밀접성을 시사한바 있다. Visher와 O'sullivan은 정신과적 치료중에서 일상생활에서 경험되어지는 의사소통과 대인관계속에서 학습되어지는 여러 가지가 있기 때문에 매일의 활동획이 치료적 방향으로 계획되어 져야 한다고 말했다. Maxwell Jones 또한 치료적 환경의 유용한 가동은 전 직원의 기여에 있으며 이는 정신건강을 최적으로 올려 줄 것이다. 라고 말했다. 이러한 상황에서 간호원은 의미 없이 환자의 감정 욕구를 깨닫지 못하고 감정지지를 주지 못하며 정서적 긴장을 예방하지 못한 체 환자와의 관계를 유지한다면 현대간호의 개념에서 이탈되어지고 발달되어지지 못한 미숙아 현상이 유지 될 것이다. 보다 바람직한 치료적 환경 유지는 간호로써 환자에게 기여해 주는 일이다. 간호의 역활과 더불어 전문적 태도는 따뜻하고 포용성 있게 그리고 융통성 있게 대함은 물론 간호인 자신의 "자기이용"을 깊이 그리고 치료적으로 이용할 것을 깨달아야 할 것이다. 즉 정신과 병실에서의 간호원 존재 자제가 환자에게 미치는 영향도 고려해야 한다는 것이다. 덧붙여 환자를 위한 일주일 병동 행사표를 Model로 제시하였고 그 안에서의 간호원의 역활을 약술하였다.
