It is not easy and simple to evaluate of the range of motion (ROM) of the head and neck, although it is important clinically. This study was performed to evaluated ROM of the head and neck in eighty young korean adults (50 men and 30 women). Both side rotations, flexion, extension and lateral bending were measured, and especially side rotation was performed with cases, natural and forced rotation. And the sitting habit of most subjects (48 men and 28 women) in classroom or theater were studied with questionnaire. Natural rotation in men was larger in right than left side (left : right=51.1.degrees: 53.9.degrees). Forced rotation was not significant between right and left sides in men and women, and between men and women (left : right=77.6.degrees: 76.8.degreesin men; left : right=77.4.degrees: 76.2.degrees in women). Flexion was larger in men (65.7.degrees) than women (58.9.degrees). The rage of the extension were 84.3.degrees and 80.0.degrees in men and women. Right lateral bending was larger in men than women (42.1.degrees and 38.6.degrees). The subjects dominant in the left or right rotation preferred to center of classroom generally (72.7% and 81.2%). In case that the subjects must select the one side between left and right, the subjects dominant in left rotation preferred to sit to the right (57.6%), and the subjects dominant in right rotation preferred to sit to the left (53.5%). This results suggested that this data might be the basis of ROM of the head and neck in young korean adults.

OBJECTIVE: The involvement of IGF system in hyperandrogenism and abnormal follicular development is controversial. This study is to assess whether IGF system contribute to it in the women with polycystic ovary(PCO). METHODS: Baseline serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (ADD), prolactin, thyroid stimulating hormone (TSH), free insulin-like growth factor(IGF)-I, free IGF-II, insulin-like growth factor binding protein(IGFBP)-1, and IGFBP-3 were measured in twelve healthy regularly cycling volunteers and forty-two women with PCO then, the changes of baseline serum levels were evaluated after laparoscopic ovarian electrocauterization in nine PCO patients. In addition, the expression pattern of IGF-I and IGF-II was examined in the ovary of control and PCO group. RESULTS: Baseline levels of LH, ADD, free IGF-II, and IGFBP-3 were significantly higher in PCO group. However, there were no significant differences in the levels of free IGF-I and IGFBP-1, although free IGF-I showed decreasing tendency in PCO group. And there was a significant positive correlation between the LH and free IGF-II level in the PCO(P=0.011, r2=0.3899), but not in the control. After ovarian electrocauterization, LH, T, and ADD levels decreased, and free IGF-I and IGFBP-3 level increased. While free IGF-II and IGFBP-1 level showed no significant changes. In the ovary, expression of both IGFs showed similar pattern in normal and PCO ovaries. CONCLUSIONS: The elevated IGFBP-3 level may alter the bioavailability of IGF(s) in the PCO. The change in IGF-I level and resumption of ovulation after electrocauterization, suggest a possible role of IGF system in the impairment of follicular development in the PCO.

The anterior cruciate ligament(ACL) is one of the most important structure for maintenance of the sta- bility of the knee joint. Chronic instability as a result of insufficiency can lead to functional disability, pain, meniscal tears, and degenerative change in articular cartilage. The incidence of injuries of this liga- ment is increasing tendency due to development of vehicle system, industrial system and sports activities. Different authors have recommended both operative and nonoperative treatment for anterior cruciate ligament injuries. Variable methods for functional recovery of anterior cruciate ligament were introduced and argued about ideal method. As arthroscopic techniques improve, surgeons are more inclined to rec- ommend surgical treatment. The methods of repair of acute rupture of the anterior cruciate ligament through the arthrotomy tech- nique have been used widely, but the arthroscopic repair is a relatively new technique. This arthroscopic technique is idealy applicable for rupture at femoral and tibial attachment site. A arthroscopic repair of anterior cruciate ligament was performed with use of the arthroscopy, in 15 consecutive, selected anterior cruciate ligaments that were ruptured at femoral or tibial attachment site, and within 2 weeks after injury. The 15 patients were followed for a minimum of one year(mean, eighteen months; maximum, thirty-eight months). The mean age of the 15 patients at the operation was thirty years(range, seventeen to forty-eight years). The results of arthroscopic repair of anterior cruciate ligament in 15 cases were satisfactory, and as fol- lows. l. All of the 15 cases, the laxity of repaired anterior cruciate ligaments were decreased. 2. The average Lysholm Knee Score Scale was increased from 16 points preoperatively to 89 points postoperatively. Five of the patients(33%) were rated as excellent, and ten patients(67%) were rated as good. 3. The range of motion of the repaired knee joints were from Oo to 135o that results were achieved at postoperative 6 months.

Purpose: This study aimed to grasp the correlation between communication ability, empathy, and interpersonal relations among nursing students, and to explore the mediating effect of empathy on the relation between communication and interpersonal relation in nursing students. Methods: Participants were 209 college students in the Department of Nursing at two universities. The data collection period was from October 1, 2019 to November 1, 2019. The questionnaire consisted of measuring tools for general characteristics, communication ability, interpersonal relation and empathy. SPSS/23.0 program was used. The analysis used descriptive statistics, Pearson's correlation coefficient, independent t-test, one-way ANOVA, multiple regression analysis, and Sobel's tests. Results: The communication ability was nursing major satisfaction (t=8.25, p<.001), and last year's average grade (t=7.29, p=.001). Interpersonal relationships showed significant differences in gender (t=2.51, p=.013) and nursing major satisfaction (t=10.99, p<.001). Communication ability and empathy (r=.37, p<.001), communication ability and interpersonal relation (r=.77, p<.001), empathy and interpersonal relation (r=.43, p<.001) showed a significant static correlation. In communication ability and interpersonal relation, empathy had a partial mediating effect (Z=2.97, p<.001), and explanatory power was 62%. Conclusion To improve the communication ability and interpersonal relation of nursing students, it is necessary to develop a personalized and empathy-enhanced education program for each grade.

BACKGROUD: The purpose of our study was to evaluate the usefulness of the ictal semiology, interictal and ictal electro-encephalography(EEG), brain magnetic resonance imaging(MRI), interictal and ictal single photon emission computed tomography(SPECT), positron emission tomography(PET) and neuropsychometry for localization or lateralization of the ictal onset zone, and analyze the result of surgical treatment. METHODS: We evaluated 13 children with intractable temporal lobe epilepsy, who are diagnosed at children's hospital of Seoul National University, from January 1995 to August 1996. The ictal onset zone was determined by ictal semiology, electrophysiologic study, structural and functional neuroimaging, and neuropsychometry. RESULTS: 1) Ictal semiology : Sixty-nine% of the studied children had change of consciousness, 62% had automatism, 31% had aura, 23% had contralateral versive movement, and 23% had contralateral dystonic posturing. Secondarily generalized seizure occured in 38% of them. 2) Interictal EEG showed localized or lateralized value in 8 cases(62%). In interictal EEG, 12 cases(92%) showed epileptiform discharges on the ipsilateral temporal lobe. 3) Magnetic resonance imaging revealed ipsilateral temporal lobe lesion in 8 cases(62%). Interictal SPECT was performed in 6 cases, only one of them had decreased cerebral blood flow on the ipsilateral temporal lobe. Ictal SECT was done in all, 8 cases(67%) had localized or lateralized value. PET was performed in 11 cases, 8 cases(73%) of them had localized or lateralized value. 4) Neuropsychometry was performed in 7 cases, 6 cases(86%) of them had localized or lateralized value. 5) Nine patients underwent epileptic surgery, 6 of them had class I outcome and each one of the rest had class II, class III and class IV. CONCLUSIONS: Electroencephalography, neuropsychometry, MRI, ictal SPECT, and PET are valuable for localization and lateralization of the ictal onset zone, but interictal SPECT is valuless. The outcome after surgery is relatively good, but more extensive study including patient's social, cognitive and emotional status will be necessary.

PURPOSE: This study was designed to examine the effects of abdominal meridian(Kyongrak) massage on menstrual cramps and dysmenorrhea. METHOD: Eighty-five women (of 110 screened) enrolled in this study and were employed full-time with more than 6.0 points(in 0~10.0 VAS scale) in menstrual cramps or more than 20 points on the dysmenorrhea scale(range 13~52). The forty-two participants in the experimental group received abdominal meridian massage for 5 minutes per day during 6 days from the fifth day before menstruation to the first day of menstruation and the forty-three participants in the control group didn't receive any treatment. Data were collected from June 1st to August 30th, 2003 and analyzed using descriptive statistics, chi2-test, and t-test. RESULT: Menstrual cramps and dysmenorrhea of the experimental group were significantly lower after abdominal meridian massage than those of the control group (p<.001). CONCLUSION: Abdominal meridian(Kyongrak) massage was very effective for relief of menstrual cramps and dysmenorrhea. Therefore, we suggest that abdominal Kyongrak massage can be a useful nursing intervention for women with menstrual cramps or dysmenorrhea.
