치관부 파절이나 치아결손 혹은 치아형태의 이상이나 변색된 치아등으로 보철치료가 요구되는 경우 저작, 연하, 발음등의 회복과 심미적인 회복이 중요한 목적이 되며, 전치부에서는 심미성이, 구치부에서는 기능적인 회복이 더욱 강조된다. 보철치료후 치료목적을 달성하고 건강한 구강내의 상태를 유지하기 위해서는 보철물이 지대치 및 주위조직에 생물학적으로 조화되어 병적상태를 유발시키지 않아야 하며, 이를 위해서는 시술전에 올바른 진단과 적절한 치료계획을 세우고, 지대치 형성, 인상채득 및 임시관 장착, 금속관 및 가공의치 제작, 구강내의 시적(try-in), cementation등 모든 과정을 주위조직과 관련하여 주위 깊게 행하여야 한다.

본 연구는 기업과 그 기업이 속한 사회에서 사업을 영위하면서 자연재해의 발생이나 COVID-19와 같은 감염병의 유행으로 조직의 업무 중단이 발생하고 난 뒤 다시 사업을 재개하는 데에는 회복탄력성이 중요하다. 기업의 회복탄력성은 기업을 경영하는데 필요한 수많은 요소와 관련이 있다. 또한 기업과 연결된 많은 네트워크와 인프라에 의존하고 있다. 회복탄력성은 재난을 당한 뒤에 다시 사업을 영위하는 능력이라 할 수 있다. 재난에 대응하는 저항의 능력 보다는 기업의 핵심 기능이 단기간에 연속성을 확보하는데 그 의의가 있다고 하겠다. 이를 위하여 기업의 재난에 대한 '예방 활동', '대비 활동', '대응 활동'을 필수 요소로 삼고 있다. 그 외에 회복탄력성에 영향을 미치는 요인을 연구하기 위하여, 여유 자원, 협력관계, 전략적 유연성, 혁신성, 기술 변화 대응력이 조직역량에 미치는 영향력을 파악하고, 조직역량이 기업의 회복탄력성에 기여하는 정도를 파악하고자 하였다. (권재득, 2018). 회복탄력성의 미치는 추가요인인 외적 효과 분석에 대한 연구를 제안한다.

Patients undergone partial maxillectomy experience post-operative masticatory, phonetic, and swallowing difficulties. They also encounter social and psychological challenges due to changes in their facial appearances. Thus, functional and esthetic recovery through maxillofacial prosthesis becomes significant for these patients. The objective of an appropriate obturator is to restore palate and improve phonetic and swallowing ability by separating the oral cavity, nasal cavity, maxillary sinus, and nasopharynx. In this case report, an obturator was fabricated for a patient who had partial resection from the maxillary posterior region to the pharynx due to squamous cell carcinoma. The purpose of this case study is to describe the results because the patient was successfully improved both functionally and esthetically.

This study was to assess the effects of a recovery oriented integrated rehabilitation program on cognitive social function, rehabilitation motivation, and mental health recovery. This program is involved motivation enhancement program with 4 subprograms composed of cognitive rehabilitation, emotion management, vocational rehabilitation, family education program. The subjects were 34 patirents with schizophrenia who had been hospitalized at National Mental Hospital on local area. The study was a non-equivalent control group non-synchronized design with two groups, an experimental group(18 patients) and a control group(16 patients). The collected data were analyzed using SPSS 12. 0. The results of the data show that there was not a significant increase in the symptom, cognitive and social function. But there was a significant increase in readiness of rehabilitation(maintenance, p=.027) and mental health recovery (p=.039). Short term recovery oriented integrated rehabilitation programs in inpatient settings are more available for motivation of rehabilitation and mental health recovery than symptom reduction or functional improvement. Therefore there should be more efforts to create more recovery oriented service provision in clinical settings.

본 연구는 관절가동범위 및 근력강화운동, 반복적인 과제-지향적 활동으로 구성된 복합운동프로그램을 뇌졸중 환자에게 2년 4개월 동안 적용하여 상지 기능 및 균형 능력에 미치는 효과를 알아보고자 하였다. 연구대상자는 뇌졸중으로 인한 좌측 편마비 증상을 보이는 68세 여성으로 매 회기 1시간씩, 주 3회, 2년 4개월 동안 복합운동프로그램을 수행하였다. 대상자의 상지 기능은 브론스트롬의 손 회복 단계와 상지 회복단계, Fugl-Meyer Assessment of Motor Function, 뇌졸중 상지기능검사로, 균형 능력은 Tinetti Gait & Balance Scale로 평가하였다. 연구 결과 대상자의 상지 기능과 균형 능력이 유지 및 향상 되었다. 이를 통하여 만성 뇌졸중 환자에서 상지 및 균형 능력의 유지 및 증진을 위한 지속적인 복합 운동프로그램 수행의 유효성을 확인할 수 있었다.

Objective : This case study was to verify effects of cognitive rehabilitation and swallowing rehabilitation on Hypoxic-Ischemic Brain Injury patient by Suicidal Attempt. Methods : The subject was a 32-year old Hypoxic-ischemic brain injury patient by suicidal attempt. He received treatment once a day five times a week, for a half an hour for each session from September 8th to December 16th, 2016. Treatment were cognitive and swallowing rehabilitation. He was assessed based on Mini-Mental State Examination-Korean (MMSE-K), Korean-Modified Barthel Index (K-MBI), Computerized Neurocognitive Function Test (CNT), Videofluoroscopic Dysphagia Scale (VDS), American Speech-Language-Hearing Association National Outcomes Measurements System (ASHA-NOMS). Results : The patient's total MMSE-K score increased from 25 to 27. His K-MBI score increased from 74 to 88. His memory, attention span, and executive function (DST, VST, SWCT, WCST) by CNT scores were improved. VDS score has no changes to 34, 44.5 and 34. ASHA-NOMS score also has no change to 6, 2 and 6. Conclusion : The study showed that the application of the treatment of cognitive and swallowing in hypoxic-ischemic brain injury patient by suicidal attempt results has positive effects on cognitive functions, and swallowing function.

There has been no general agreement about optimal time for nerve surgery in the closed brachial plexus injury(BPI). From our early experiences, we knew by chance that spontaneous recovery in BPI patients may begin even later than 8 months after injury. Authors' strategy, which was based on our early experiences, for the treatment of closed fresh injury was 'wait and see' unlit 8 months after injury. From 1985 to 1994, we observed 103 patients with BPI. All of them did not have any operation until 8 months after injury. There were 95 men and 8 women with a mean age of 29 years. Motorcycle injury(31%) and vehicle accident(28%) were main causes of injury. Whole plexus types were observed in 56 patients(54%), upper plexus types in 29(28%), lower plexus types in 3(3%), and infraclavicular types in 15(15%). Electromyography was performed in all patients. This was repeated every three months to detect the recovery. Results were evaluated by authors' criteria, in which AMA system of brachial plexus impairment was modified. Duration of follow up was average 25 months. 47 patients(46%) showed spontaneous improvement, which was initially detected at average 7.8 months(range,3 months-16 months) after trauma by electromyography. The average score of these 47 patients improved from 14.8 points to 39.8 points.31 patients(30%) had nerve surgery such as nerve graft, neurotization or neurolysis. Average duration from injury to nerve surgery, was 10 months. Among 31 patients who had nerve surgery, 16 patients improved from preoperative 21.5 points to postoperative 36.3 points in average. Because spontaneous recovery began in average 7.8 months after injury, we think that it would be better to 'wait and see' for at least one year in patients with closed BPI expecting spontaneous recovery.

Ischemic preconditioning is known to have protective effect on myocardial function at prolonged ischemic insult but the mechanism of the effect is not clearly known. The effect of the preconditioning on the global ischemia using cardioplegic solution is not well known. To evaluate the effect of global myocardial preconditioning on the functional recovery after cardioplegic arrest and two hours of hypothermic storage, we used the isolated rat heart and two hours cardioplegic arrest time at $0^{\circ}C$. In the experimental group(n=10), after baseline functional data was obtained, ischemic preconditioning was induced with 1 min of global normothermic ischemia for three times before the arrest period. In the control group(n=10), hearts underwent no ischemic precondi- tioning. After 2 hrs of cardioplegic arrest and storage in the $0^{\circ}C$ cardioplegic solution reperfusion was done and hemodynamic data were collected at post-reperfusion 20 min. Heart with ischemic preconditioning showed improved functional recovery at post reperfusion 20 min in peak developed pressure and dP/dT. In percent change of the peak pressure, preconditioning group showed 93.20$\pm$15.7% recovery rate compared to baseline data, and control group showed 67.3$\pm$15.6% recovery rate. In percent change of the dP/dT, control group showed 54.7$\pm$18.2% recovery rate and preconditioning group showed 78.1$\pm$15.1% recovery rate. Percent changes in heart rate and coronary flow showed no significant difference between two groups and there was no significant differences in amount of cardioplegic delivery between groups. Our data suggest ischemic preconditioning may have protective effect on recovery state after cardioplegic arrest and 2 hr ischemic storage of isolated rat heart and its mechanism is not related to the amount of the cardioplegic delivery amount.
