Germinal matrix and intraventricular hemorrhage (GM-IVH) are the major causes of intracranial hemorrhage in premature infants. Cranial ultrasound (cUS) is the imaging modality of choice for diagnosing and classifying GM-IVH. Magnetic resonance imaging (MRI), usually performed at term-equivalent age, is more sensitive than cUS in identifying hemorrhage in the brain. Post-hemorrhagic ventricular dilatation is a significant complication of GM-IVH and correlates with adverse neurodevelopmental outcomes. In this review, we discuss the various imaging findings of GM-IVH in premature infants, focusing on the role of cUS and MRI.

주택임대차보호법은 임차인의 주거생활과 법적지위를 개선하기 위하여 1981년 3월5일 법률 제3379호로 제정된 이후에 많은 문제점은 있었으나, 몇 차례의 개정을 걸쳐 종래의 미흡했던 부분을 개선하기도 했었다. 하지만 무주택영세민들의 지위강화를 실질적으로 보장해 주기 위해서는 아직도 많은 문제점을 해결해야할 필요성이 제기되고 있는 가운데, 국회는 2015년 2월14일 임차인 계약갱신청구권 도입을 두고 서민주거복지특별위원회를 가동하여 임시국회에서 현안을 논의하기로 했었으나 현재 찬반양론의 대립이 뚜렷하게 보이고 있는 실정이다. 그동안 임차인의 계약갱신청구권이 보장되지 않았었기 때문에 임대차의 최단존속기간이 경과하게 되면 임대인의 의사에 따라 계약갱신의 여부가 좌우됨으로서 무주택영세민들의 주거안정이 불안정할 수 있었다. 따라서 본 논문에서는 열악한 지위에 있는 임차인들의 주거생활 안정을 위해 우리의 존속기간규정을 분석하고, 각국의 존속기간과 비교 검토를 통하여 문제점에 대한 구체적인 입법방안을 제시하고자 한다.

52 cases of ventricular septal defect [VSD] associated with aortic insufficiency [Al] were found among 1271 patients with simple VSD operated during 27-year period [1959, August-1987, June] at Seoul National University Hospital. Their preoperative data, intraoperative findings and postoperative short-term and long-term follow-up data were evaluated to find the proper timing and method of surgical treatment. The result of this survey shows as follows: 1. To obtain the proper surgical indication, cardiac catheterization and angiography, especially root aortography, was essential. 2. Of all 52 patients, the VSD were type I in 40 patients [77%], type II in 8 [15%] and combination of type I and II in 4 [3%]. Patch closure of VSD were performed in 46 patients and direct suture closure of small VSD in 6. Most common pathologic findings of Al were prolapse of right coronary cusp [40 cases, 77%]. Aortic valve reconstruction were performed in 19 patients, aortic valve replacement in 6 and VSD closure alone in 27. 3. There were 3 surgical deaths [mortality 5.8%], and the long-term follow-up shows that VSD closure alone might have been sufficient to arrest progression of Al in younger patients [less than 10-year old], particularly in those with mild insufficiency. Valve reconstructions, when necessary, were more effective when done at an early age [less than 15-year old]. In a conclusion, we could recommend followings: 1. If patient at any age having VSD with Al is diagnosed, prompt operation is recommended. As for the surgical method, VSD closure only may be fit for mild degree of Al when patient is less than 10-year old, but the management of valve itself may be needed for moderate to severe degree of Al, especially when patient is over 10 year old. The management of valve itself may be variable, but valve reconstruction should be considered as a first choice in less than 15-year old patient. If patient is diagnosed less than 5-year old without evidence of Al, close follow-up observation is recommended. But if Al evidences of clinical findings and/or echocardiography during follow-up examination are notified, corrective operation should be accomplished while the Al is mild. If cusp prolapse and/or even type I VSD of significant size is demonstrated on aortogram, without Al, it should be corrected as early as possible before the patient is about 5 years old.

Purpose: The Mulliken's method is a one of the very excellent technique to correction of the unilateral cleft lip. It could decrease the need of additional operation and second operation by the early simultaneous correction of unilateral cleft lip and nasal deformity, at a time. Numerous procedures were advocated for the correction of nasal deformity, but with general dissatisfaction of the results, it became obvious that no one procedure is the ideal one. The authors have been operating on unilateral cleft lip by Mulliken's method and long term follow - up of postoperative result was evaluated. Methods: The authors have done long term follow - up of result in the 75 cases unilateral cleft lip patient, during 1 ~ 7 years. That was repaired by simultaneous correction of cleft lip and nasal deformity by Mulliken's method at the period from June, 1997 to December, 2007. The patients were unilateral complete cleft lip 39 cases, unilateral incomplete cleft lip 36 cases. In the severe complete cleft lip cases, lip adhesion operation was done before definite operation. The mean age of unilateral cleft lip operation was 3.2 months. Five anthropometric parameters, which were upper lip, cutaneous lip and vermilion mucosa height, nasal tip protrusion, columella length were measured by Sliding Vernier Caliper. The anthropometric analysis was performed preoperative and postoperative at 6 months, 3, 5 and 7 years and the results were com pared with those of age - matched, normal children. T - tests were used to analyze the differences between the measurements. Results: Long - term postoperative results were evaluated by anthropometrically. Most patients showed adequate growth of upper lip height, vermilion mucosa height and columella length. But nasal tip protrusion was relatively short compare with normal value. Incomplete cleft lip group was nearly normal growth results than complete cleft lip group. Conclusion: In conclusion, we could make harmonious Cupid's bow, natural philtrum and lip, appropriate nasal shape by Mulliken's method. But nasal tip protrusion was under the normal values on complete and incomplete group. And incomplete group was more good results than complete group. We have experienced repair of cleft lip by Mulliken's method with 75 cases of unilateral cleft lip patients and conclude that it was very useful and good method.

일 공공기관 S보훈병원과 상호 연계된 협진체제를 구축하여 운영하고 있는 V요양병원 환자들의 특성 및 사망위험요인을 파악하여, 양질의 의료서비스를 제공하는 것을 목적으로 한다. V요양병원에서 2017년 1년 동안 850명의 퇴원 환자를 대상으로 2020년 3월1일부터 5월31일까지 3개월 동안 추적조사를 하였다. 조사분석 결과 V요양병원 입원환자는 최저 37세에서 최고 100세로 평균연령은 79.2세, 70세 이상이 86.4%로서 타 선행연구보다 연령 비중이 높았다. 국가유공자가 75.4%로서 유가족이나 일반인 환자보다 3배 이상 높았다. 주진단명은 치매 질환이 22.2%로 가장 많았으며, 심혈관질환, 마비증후군 순이였다. 평균재원일수는 160일이였으며, 재원일수 180일 이상이 46.4%로서 일반 요양병원의 37% 보다 높은 것으로 나타났다. 남성 사망률이 여성보다 높고, 국가유공자는 사망이 생존보다 높은 것으로 나타났다. 사망위험요인은 연령과 재원일수 이었다. S보훈병원으로 전원이 높은 것은 응급센터/재활센터/심혈관센터 등의 진료 이용이 신속하고, 다양한 회복치료가 가능하기 때문이다. V요양병원 중증 만성질환자들에게 S보훈병원으로의 전원은 진료이용이 신속하고 다양한 회복치료의 효과가 높으므로 협진체계를 확대 운영하여 요양병원 만성질환자들에게 건강 회복을 통한 행복한 삶의 질을 높여야 할 것을 시사한다.

The purpose of this study was to compare and analyze the effect of twelve-week Taekwondo and walking exercises on the double-leg balance control by dividing elderly females into Taekwondo, walking exercise and control groups. In total, 30 elderly females were randomly divided into Taekwondo, walking exercise, and control groups, with 10 subjects in each group. Subjects participating in this study were 10(age $69.4{\pm}5.8$ years), 10(age $71.4{\pm}7.6$ years) and 10(age $70.6{\pm}4.8$ years) in the three groups, respectively. Although the AP measures were not significantly different among the groups and times, the ML RMS distance and ML velocity, among the ML measures showed a significant difference among the groups and times. Average velocity and 95% confidence ellipse area were also significantly different among the groups and times. Twelve-week Taekwondo and walking exercises were found to be effective in improving static balance control. Future studies on the development of a Taekwondo intervention program tailored for the elderly with many subjects conducted by using a long-term training program are expected.

Reduced fetal growth is independently associated with increased risk of health problems in later life, particularly type 2 diabetes and cardiovascular diseases. Insulin resistance appears to be a key component underlying these metabolic complications. It is suggested that detrimental fetal environment may program insulin resistance syndrome. An insulin-resistant genotype may also result in both low birth weight and insulin resistance syndrome, and it is likely that the association of low birth weight with insulin resistance is the result of both genetic and environmental factors. Early postnatal rapid catch-up growth is closely related to risk for subsequent metabolic diseases. Fat mass is strikingly reduced in neonates born small for gestational age (SGA), and recent data suggest that insulin resistance seen in catch-up growth is related to the disproportionate catch-up in fat mass compared with lean mass. Endocrine disturbances are also recognized in SGA children, but overt clinical problems are infrequent in childhood. Cognitive impairment is reported in some children born SGA, especially those who do not show catch-up growth, in whom early neurodevelopmental evaluation is required. Breast feeding, also known to be protective against the long-term risk of obesity, may prevent some intellectual impairment in SGA children. Calorie-dense feeding does not seem to be appropriate in SGA infants. We must balance the positive effect of nutrition on neural development against rapid fat deposition and the future risk of insulin resistance.

The purpose of the present research was to investigate cross-modal transfer, especially tactual-to-visual transfer in infancy and to study the relation between failure of cross-modal transfer performance and length of familiarization period. The subjects of this study were 60 infants, 10 boys and 10 girls at each level: six, nine, and twelve months of age. All were normal, healthy, full-term babies. The mothers' educational achievement was controlled at more than 12 years of schooling. There were two separate experimental conditions, one 30-sec and one 60-sec familiarization period. Each experimental condition consisted of a tactual familiarization and a visual recognition memory test. Each child was presented with these 2 sets of cross-modal stimuli in one of the 2 experimental conditions. Infants' visual responses in the visual recognition memory test were videotaped for 20 seconds. Visual fixation time to novel and familiar stimuli was observed throughout the test. The data was analyzed with t-test, percentage of total fixation time to novel stimuli, and ANOVA. The results showed that: 1) Significant differences were found in the cross-modal transfer performance from touch to vision between the 3 age groups. This is, 6 and 9 month old infants didn't show cross-modal transfer in the 30-sec condition, but 12 month old infants did show cross-modal transfer in the 30-second. 2) In all 3 age groups, no significant differences were found in cross-modal transfer performance between the two conditions.

Although human-sized bipedal humanoid robots have been developed as the ideal form of human-friendly robots, studies of humanoid robots from the user perspective and of actual interaction between humanoid robots and the public in daily environments are few. This paper presents a long-term public demonstration that encouraged interaction between a humanoid robot and unspecified individuals. We have collected a significant amount of subjective evaluation data from the public by performing a storytelling demonstration that enhanced people's empathy towards the robot. The evaluation model consists of the robot's human friendliness, which involves its impression on humans, interaction with humans, and imitation of human motions and the robot's human appearance which involves gender, age, height, and body type. This study shows that there is no significant difference in human-friendliness between gender groups (male and female), while there is a significant difference between age groups (children and adults). In human appearance, it appears that there is no significant difference between either gender groups or age groups, except for the case of the robot's height.

Objective : This study examined benzodiazepine prescription patterns of outpatients visiting the psychiatry department in a single general hospital in Korea. Methods : A retrospective descriptive analysis of benzodiazepine prescriptions was performed on a database from 2014 in a general hospital in Korea. We analyzed the following factors of adult outpatients: demographic factors such as sex and age, amount of benzodiazepine prescribed, treatment duration, and diagnosis based on the ICD-10. Results : In 2014, benzodiazepines were prescribed to 46.4% of the outpatients. Percentage of benzodiazepine prescription increased with age and was highest in the age group 40-59 years. Prescription was more prevalent in women and the prescription percentage increased by treatment duration. Patients with the F4 diagnosis (neurotic, stress-related and somatoform disorders) were the most highly prescribed group. For all diagnosis groups, prescription was more prevalent in females or similar for both sexes except for patients with F5 diagnosis (behavioral syndromes associated with physiological disturbances and physical factors), with males being more predominant. Conclusion : Despite the concern regarding the rate of benzodiazepine prescription and administration to geriatric patients, long-term prescription and usage among older patients is still prevalent.
