  • 본 논문에서는 무의식의 창조성이 종교와 어떻게 연결되는지를 그리스도교를 중심으로 살펴보려 한다. 융은 인간의 무의식을 과학적으로 연구하려 했던 프로이트의 무의식관이 오직 자아에 의해 무의식적으로 억압되어 있는 부문만을 포함하고 있음을 비판하면서, 무의식의 범위에는 억압된 내용뿐만 아니라 의식의 문턱값에 이르지 못한 모든 심리적 소재가 광범위하게 포함되어 있는 것으로 파악했다. 또한 인간 정신 역시 전적으로 개별적인 현상일 뿐 아니라 집단적 현상이기도 한 것이기에, 이러한 집단정신이 정신기능의 하부를 포괄하고 있고, 의식과 개인적 무의식은 정신기능의 상부를 포괄하는 것으로 보았다. 무의식은 자기조절의 기능을 지니고 있음을 융은 다양한 임상경험과 스스로의 체험을 통해서 알게 되었다. 그러므로 무의식은 '요구'할 수 있을 뿐만 아니라 자신의 요구를 다시 거두어들일 수도 있는 것이다. 이러한 기능을 융은 무의식이 지닌 자율성으로 보았으며, 이처럼 자율적으로 움직이는 무의식이 창조적으로 만들어내는 꿈이나 환상을 통한 상(像)들은 풍성한 관념뿐 아니라 감정을 포함하는 모든 것이다. 무의식의 이러한 창조적인 상들이 인간이 본래의 자기(Self)를 찾아나가는 '개성화의 과정'을 도와주고 이끌어나가는 것이다. 이처럼 자아의식을 보상하는 무의식의 과정은 전체 정신의 자가조절에 필요한 모든 요소를 지니고 있어 창조적인 방법으로 자율적으로 작용하는 것이다. 융이 체험했던 종교란 바로 무의식의 창조성과 자율성에 의해 움직여지는 집단의식의 상들이 의식을 사로잡아 형성된 '누미노줌'에 대한 숙고의 자세이며, 종파란 바로 이러한 상(像)들이 제의(ritual)나 의식으로 굳어져 신앙 공동체로 형성된 것이다. 융은 종교를 최고, 혹은 가장 강력한 가치와의 관계로 파악하고, 이러한 관계는 양면적, 즉 자유의지에 의한 것이기도 하고 불수의적인 것이기도 한 것으로 보았다. 따라서 사람들은 하나의 가치, 즉 어떤 에너지가 부하된 정신적 요소에 의해 무의식적으로 사로잡힐 수도 있고, 혹은 그것을 의식적으로 수용할 수도 있게 된다. 융은 인간 속에서 최대의 세력을 갖고 있는 압도하는 정신적 요소, 또는 그러한 심리학적 사실이 신(神)으로서 작용하는 것으로 보았다. 융은 어린 시절부터 스위스 개혁교회의 전통적인 분위기에서 자랐지만 자신을 헌신적인 그리스도교인 으로 생각하지는 않았던 것 같다. 그에게 다가온 기독교는 지적(知的) 정직성도 부족했고 영적인 활력도 부족한 생명력이 사라진 습관적이고 관례적인 한 기관일 뿐이었다. 융은 12살 때 자신의 환상을 통해 만났던 극적인 종교적인 체험을 통해서 자신의 무의식 안에 살아있는 신의 존재를 인식했기에, 일생을 통해 끊임없는 신학적인 질문과 삶 안에 얽혀있는 종교적 문제들과 대면했다. 이는 분명히 제도화된 그리스도교의 소생을 위한 융 자신의 개인적인 관심이고 사랑이었음을 이 논문에서 밝혀보려 한다.

  • Background: Vitamin K antagonist (VKA) to prevent thromboembolism in non-valvular atrial fibrillation (NVAF) patients has limitations such as drug interaction. This study investigated the clinical characteristics of Korean patients treated with VKA for stroke prevention and assessed quality of VKA therapy and treatment satisfaction. Methods: We conducted a multicenter, prospective, non-interventional study. Patients with $CHADS_2{\geq}1$ and treated with VKA (started within the last 3 months) were enrolled from April 2013 to March 2014. Demographic and clinical features including risk factors of stroke and VKA treatment information was collected at baseline. Treatment patterns and international normalized ratio (INR) level were evaluated during follow-up. Time in therapeutic range (TTR) > 60% indicated well-controlled INR. Treatment satisfaction on the VKA use was measured by Treatment Satisfaction Questionnaire for Medication (TSQM) after 3 months of follow-up. Results: A total of 877 patients (age, 67; male, 60%) were enrolled and followed up for one year. More than half of patients (56%) had $CHADS_2{\geq}2$ and 83.6% had $CHA_2DS_2-VASc{\geq}2$. A total of 852 patients had one or more INR measurement during their follow-up period. Among those patients, 25.5% discontinued VKA treatment during follow-up. Of all patients, 626 patients (73%) had poor-controlled INR (TTR < 60%) measure. Patients' treatment satisfaction measured with TSQM was 55.6 in global satisfaction domain. Conclusion: INR was poorly controlled in Korean NVAF patients treated with VKA. VKA users also showed low treatment satisfaction.

  • Objectives To examine direct causes of attempted suicides, methods adopted to commit suicide, and psychiatric diagnoses among suicide attempters in South Korea. Methods A total of 1359 suicide attempters who had visited emergency department of 17 medical centers due to suicide attempt from May 2013 to Nov 2013 were interviewed using semi-structured questionnaires. Results Psychiatric symptoms were the most common cause of suicide attempts (62.2%), followed by interpersonal relationships (24.4%). Women attempted suicide more often for interpersonal reasons, whereas men were more likely to do so for financial and job-related reasons. Half of participants (55.8%) attempted suicide by drug intoxication, which was more prevalent among females and those who had previous history of psychiatric disease or previous suicide attempt. Men were more likely to use more lethal methods such as pesticide poisoning and gas inhalation than women. Pesticide poisoning was also prevalent among the elderly group and the rural population. Near ninety-five percent (94.5%) of participants received a psychiatric diagnosis : the most frequent diagnosis was depressive disorder. Conclusions This is the first nationwide study of cases of attempted suicide. When stratified by age groups, gender, urbanicity, living alone or not, presence of physical illness, previous psychiatric history, and previous suicide attempt, there were significant differences with respect to causes, methods of attempted suicides and psychiatric diagnoses of suicide attempters.

  • Objective: This study aimed to evaluate the effect of implementing the consensus statement from the Asian Society of Cardiovascular Imaging-Practical Tutorial 2020 (ASCI-PT 2020) on the reliability of cardiac MR with late gadolinium enhancement (CMR-LGE) myocardial viability scoring between observers in the context of ischemic cardiomyopathy. Materials and Methods: A total of 17 cardiovascular imaging experts from five different countries evaluated CMR obtained in 26 patients (male:female, 23:3; median age [interquartile range], 55.5 years [50-61.8]) with ischemic cardiomyopathy. For LGE scoring, based on the 17 segments, the extent of LGE in each segment was graded using a five-point scoring system ranging from 0 to 4 before and after exposure according to the consensus statement. All scoring was performed via web-based review. Scores for slices, vascular territories, and total scores were obtained as the sum of the relevant segmental scores. Interobserver reliability for segment scores was assessed using Fleiss' kappa, while the intraclass correlation coefficient (ICC) was used for slice score, vascular territory score, and total score. Inter-observer agreement was assessed using the limits of agreement from the mean (LoA). Results: Interobserver reliability (Fleiss' kappa) in each segment ranged 0.242-0.662 before the consensus and increased to 0.301-0.774 after the consensus. The interobserver reliability (ICC) for each slice, each vascular territory, and total score increased after the consensus (slice, 0.728-0.805 and 0.849-0.884; vascular territory, 0.756-0.902 and 0.852-0.941; total score, 0.847 and 0.913, before and after implementing the consensus statement, respectively. Interobserver agreement in scoring also improved with the implementation of the consensus for all slices, vascular territories, and total score. The LoA for the total score narrowed from ± 10.36 points to ± 7.12 points. Conclusion: The interobserver reliability and agreement for CMR-LGE scoring for ischemic cardiomyopathy improved when following guidance from the ASCI-PT 2020 consensus statement.

  • Background: Breast cancer is the leading cause of cancer deaths among women worldwide. High breast cancer mortality has been attributed to lack of public awareness of the disease. Little is known about the level of knowledge of breast cancer in Central African Republic. This study aimed to investigate the knowledge of health professionals on breast cancer. Materials and Methods: This cross-sectional study was conducted among 158 health professionals (27 medical; 131 paramedical) in 17 hospitals in Bangui using a self-administered questionnaire. Descriptive statistical analysis, Person's ${\chi}^2$ test and ANOVA were applied to examine associations between variables with p < 0.05 being considered significant. Results: Data analyzed using SPSS version 20 indicates that average knowledge about breast cancer perception of the entire population was 47.6%, diagnosis method 45.5%, treatment 34.3% and risk factors 23.8%. Most respondents (65.8%) agreed that breast cancer is important in Central African Republic and that family history is a risk factor (44.3%). Clinical assessments and mammography were considered most suitable diagnostic methods, and surgery as the best treatment. The knowledge level was significantly higher among medical than paramedical staff with regard to risk factors, diagnosis and treatment. However the trainee group had very high significant differences of knowledge compared with all other groups. Conclusions: There is a very urgent need to update the various training programs for these professionals, with recommendations of retraining. Health authorities must create suitable structures for the overall management of cancer observed as a serious public health problem.

  • Acebrophylline is a compound produced by salifying ambroxol with theophylline-7 -acetic acid. After acebrophylline administration, the salt splits into these two components which feature a peculiar pharmacokinetic behavior, an adequate ambroxol and a low theophylline-7-acetic acid serum levels. The purpose of the present study was to evaluate the bioequivalence of two acebrophylline capsules, Surfolase (Hyundai Pharm. lnd. Co., Ltd.) and Burophil (Kuhnil Pharm. Co., Ltd.), according to the guidelines of the Korea Food and Drug Administration (KFDA). The release of ambroxol from the two acebrophylline formulations in vitro was tested using KP VIII Apparatus II method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solution and water). Twenty eight healthy male subjects, $23.25{\pm}1.43$ years in age and $64.82{\pm}6.77$ kg in body weight, were divided into two groups and a randomized $2{\times}2$ cross-over study was employed. After two capsules containing 100 mg as acebrophylline were orally administered, blood was taken at predetermined time intervals and the concentrations of ambroxol in serum were determined using HPLC with electrochemical detector (ECD). The dissolution profiles of two formulations were similar at all dissolution media. In addition, the pharmacokinetic parameters such as $AUC_t$, $C_{max}$ and $T_{max}$ were calculated and ANOVA test was utilized for the statistical analysis of the parameters using logarithmically transformed $AUC_t$, $C_{max}$ and untransformed $T_{max}$. The results showed that the differences between two formulations based on the reference drug Surfolase, were -1.64, -3.33 and -0.92% for $AUC_t$, $C_{max}$ and $T_{max}$, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log 0.8 to log 1.25 $(e.g., \;log\;0.93{\sim}log\;1.05\;and\;log\;0.88{\sim}log\;1.05$ for $AUC_t$, and $C_{max}$, respectively). Thus, the criteria of the KFDA bioequivalence guideline were satisfied, indicating Burophil capsule was bioequivalent to Surfolase capsule.

  • This research has been conducted to examine the cognition and attitude of nursing students on Oriental Nursing, the subject of this research being 789 nursing students from 9 different universities who took the Oriental Nursing class. A questionnaire, the construct validity and reliability of which have been verified through enquiries into records and references as well as preliminary researches, was used as a research tool. The questionnaire, a set of 86 questions, was developed by the researchers of this study, and the reliability of the questionnaire is Cronbach's=.85. The collected data have been analysed using SPSS windows programme 11.0 for t-test and ANOVA, and the results are as follows: 1. There was a significant difference in cognition and attitude points according to the academic year (F=14.15, p=.000). After the post-hoc test, it was revealed that the points of the students in their 4th year were significantly higher than the points of the students in their 2nd or 3rd year. 2. There was a significant difference in cognition and attitude points according to the credits the students have taken (F=28.66, p=.000). After the post-hoc test, it was revealed that the points of the students who have taken from $3{\sim}5$ to $6{\sim}8$ credits were significantly higher than the points of those who have taken from 1 to 2 credits. 3. There was a significant difference in cognition and attitude points according to the period of time the students have experienced Oriental Nursing (F=32.06, p=.000). After the post-hoc test, it was revealed that the points of the students who have practised Oriental Nursing from 1 to 2 weeks were significantly higher than the points of those who have not practised it at all. 4. There was no significant difference in cognition and attitude points according to the treatment or hospitalisation of the students themselves or their family members. 5. The cognition and attitude points of the students who are deeply interested in Oriental Nursing were significantly higher than the points of those who are not (t=8.83, p=.000). 6. The cognition and attitude points of the students who have higher expectations for the development of Oriental Nursing were significantly higher than the points of those who have not(t=5.90, p=.000). 7. The cognition and attitude points of the students who believe that the Oriental Nursing will contribute to the expansion of the roles of nurses were significantly higher than the points of those who do not (t=6.60, p=.000). 8. The cognition and attitude points of the students who expect that the Oriental Nursing will be effective in prevention of chronic diseases were significantly higher than the points of those who do not (t=5.80, p=.000). According to the results above, it was confirmed that proper education on Oriental Nursing can have affirmative effects on the cognition and attitude of the nursing students towards Oriental Nursing.

  • 목 적 : EBV 감염은 발생 연령에 따라 혈청학적으로 진단되지 않을 수 있으며, 이 때 실시간 중합효소연쇄반응이 대신할 수 있는 진단 방법이다. 본 연구는 임상적으로 EBV 감염이 의심되는 환자에서 각각 혈청학적 검사 양성인 경우와 실시간 중합효소연쇄반응 양성인 그룹간의 임상양상을 비교하고자 하였다. 방 법 : 2004년 1월부터 2006년 12월까지 EBV 감염이 의심되는 45명의 환자를 대상으로 EBV 실시간 중합효소연쇄반응 검사를 시행하여 EBV 바이러스혈증의 존재 여부를 확인하였다. $102.5copies/{\mu}g$ DNA를 EBV 연관질병의 결정 수준으로 삼았다. 결 과 : EBV 감염이 혈청학적으로 진단된 환자는 4명이었으며 실시간 중합효소연쇄반응으로 EBV 바이러스혈증이 확인된 환자는 15명이었다. EBV 바이러스혈증이 있는 환자군의 나이는 4세 미만이 73%(11/15)였고 남녀비는 1:1.3 이었다. 입원 시의 임상증상은 발열이 73%(11/15), 인두 발적이 67%(10/15)에서 보였으며 동반된 질환으로는 급성 위장관염과 폐렴이 각각 20%(3/15)였다. 비정형 림프구가 15% 이상인 경우는 27%(4/15)에서 보였고 AST, ALT의 증가가 각각 87%(13/15), 80%(12/15)였다. CRP가 2 mg/dL 이하인 경우는 87%(13/15)였다. EBV 바이러스혈증 환자중 1세 미만은 5명으로 이들 중 80%(4/5)에서 발열이 동반되었고 비정형 림프구는 보이지 않았으며 모두 AST, ALT가 증가하였다. 혈청학적으로 진단된 환자군의 나이는 1-6세였고 75%(3/4)에서 간비대와 비장비대가 보였으며 50%(2/4)에서 발열, 인두발적, 경부 림프절 종대가 보였다. 동반된 질환은 없었으며 백혈구가 모두 $20,000/mm^3$ 이상이었고 50%(2/4)에서 비정형 림프구가 증가했으며 AST, ALT가 50 IU/L 이상으로 상승하였다. CRP는 모두 1 mg/dL 이하였다. 결 론 : 혈청학적 검사에서 진단되지 않았더라고 실시간 중합효소연쇄반응에서 EBV 바이러스혈증을 보인 환자는 EBV 감염의 일반적인 임상증상을 보였다. 따라서 EBV 감염이 의심되는 환자, 특히 1세 미만의 환자는 혈청학적 검사가 음성이어도 실시간 중합효소연쇄반응을 통해 바이러스 혈증을 확인하는 것이 EBV 감염의 진단률을 높이는데 의미가 있을 것으로 사료된다.

  • The purpose of this research was to determine the effects on the healing of fibular fractures in rabbits of low-intensity pulsed ultrasound (50 $mW/cm^2$ and 500 $mW/cm^2$) applied for periods of 4, 14 and 24 days following fibular osteotomy. Thirty-six male Japanese white rabbits were randomly divided into three groups of twelve for three treatment protocols: (1) ultrasound treatment at intensities of 50 $mW/cm^2$ and 500 $mW/cm^2$ until the 4th day following fibular osteotomy, (2) ultrasound treatment at intensities of 50 $mW/cm^2$ and 500 $mW/cm^2$ until the 14th day following fibular osteotomy, and (3) ultrasound treatment at intensities of 50 $mW/cm^2$ and 500 $mW/cm^2$ until the 24th day following fibular osteotomy. The low-intensity pulsed ultrasound was applied to only one fibula of each rabbit (these served as the experimental group). The other fibula of each rabbit served as the control group. The selection of which fibula was to be treated was made randomly. The animals were sacrificed on the 4th, 14th and 24th day after the start of ultrasound treatments. Percent of trabecular bone area and fibular radiography were carried out to compare the degree of fibular bone healing. A microscope was also used to determine any histologic changes. For statistical differences in radiological changes due to length of treatment period (4, 14 and 24 days respectively), the Wilcoxon signed-ranks test was used to compare the experimental and control groups. For statistical differences in fracture healing due to differences in ultrasound intensity, radiological studies were compared using the Mann-Whitney Test. And, to compute percentage differences in areas of trabecular bone, Two-way analysis of variance (ultrasound intensity x each group) was used. Experiment results were as follows: 1. In animals sacrificed on the 4th day, no difference was found in the radiological studies of the fibulae in the experimental and control groups (p>.05). However, experimental groups showed more rapid bone repair than control group. 2. Both radiographic and percent of trabecular bone area studies showed significant differences in rabbits sacrificed after 14 days. Fracture healing was significantly increased in the experimental group (p<.05) 3. In the animals sacrificed on the 24th day, histologic study showed rapid bone repair but fibular radiologic studies did not show statistical differences between the two groups (p>.05). 4. On the 14th day, bone union on radiograph was significantly more rapid in the treatment group with pulsed ultrasound of 50 $mW/cm^2$ than the group with 500 $mW/cm^2$ (p<.05). Histologic studies showed that both the 14 and 24 days groups had more rapid bone repair in animals treated with 50 $mW/cm^2$ ultrasound intensity than those treated with 500 $mW/cm^2$ intensity. In conclusion, it has been shown that the low-intensity pulsed ultrasound has a positive effect on bone fracture healing in the early stage and the range of pulse ultrasound from 50 $mW/cm^2$ to 500 $mW/cm^2$ is effective for fracture healing. Further study is needed to investigate the influence of pulsed ultrasound on delayed union and non-union in bone fractures and also for the clinical use of low-intensity pulsed ultrasound for bone healing in humans.
