The aim of this research is to grasp the relation between lumbago incidence rate and research hypothesis in the effects of sex life of the middle-aged couples in Taejon area upon lumbago. And so, this writer had questionaired the 400 middle-aged couples in five gus, Taejon megalopolis -Jung-gu, Seo-gu, Dong-gu, Yuseong-gu, and Taedeok-gu - from April 21, 1998 to May 10, 1998. Of them, total 209 question papers were drawn back; male 102, female 107. Analysis of the data is as follows. 1. 145(69.37%) subjects of total 209 had experience in lumbago after their sexual lives. 2. In the number of sex life a week, one or two times of lumbago incidence rate were the most rate as 41.55% and each other had a statistically significant relation (P 0.01). 3. In age and lumbago incidence rate, their thirties was 37.75% and each other had a significant relation (P 0.05). 4. In weight and lumbago incidence rate, the level of $50kg{\sim}60kg$ was highest and each other didn't have a significant relation (P 0.05). 5. In the mean time of sexual life, the period of $11{\sim}20$ minutes was 29.47% and each other had a significant relation (P 0.01). 6. In week time zone of sexual life and lumbago incidence rate, midnight was the highest rate, 36.23% and each other didn't have a significant relation (P 0.05). 7. In the lumbago incidence rate according to bedroom structure of sexual life, a bed was 38.17% and each other had a significant relation (P 0.05). 8. In the lumbago incidence rate according to sexual posture, a normal position showed the highest rate, 46.12% and each other didn't have a significant relation (P 0.05). Putting the abovesaid results together, lumbago has relation to the number of sex life a week, age, the mean time of sexual life, and bedroom structure of sexual life. Therefore, it is thought that it is necessary that middle-aged couples periodically study the educational programs to make an education for lumbago prevention, etc. the key points.

Nucleophosmin (NPM1) is a protein of highly conserved nature which works as a molecular chaperone and is mostly found in nucleoli. NPM also involved in the maturation of preribosomes and duplication of centrosomes. Furthermore, it is also active in control and regulation of the ARF-p53 tumor suppressor pathway. A high rate of incidence and prognostic involvement is reported by various authors in AML patients. In AML it behaves as a favorable prognostic marker. NPM mutations are more frequently associated with normal-karyotype AML and are usually absent in patients having abnormal or poor cytogenetic. NPM mutations are not frequent in other hematopoietic tumors. Two main types of mutations have been described to date. Both of these cause abnormal cytoplasmic localization of NPM1. Their high incidence rate in normal karyoptype and their favorable nature m ake those mutations hot spot or front face mutations which should be checked before treatment starts.

본 논문에서는 접지평면위에 2개의 유전체 층을 가지는 완전도체 격자구조에서의 전자파 산란문제를 간단한 방수치해석 방법으로 잘 알려진 PMM방법을 적용하여 입사각에 따라 수치해석하였다. 산란전자계는 Floquet 모드 함수의 급수로 전개하였다. 경계조건은 미지의 계수를 구하기 위하여 적용하였고, 도체의 경계조건은 접선성분의 전계와 스트립 위의 전류와의 관계를 위해 적용하였다. 입사각이 수직일 때 비유전율이 증가함에 따라 기하광학적 반사전력의 변하는 최소점은 스트립 폭이 높은 값으로 이동한다는 것은 주목되며, 이때 수직입사시 대부분의 전력은 다른 각도의 방향으로 산란된다.

Objectives: Prehypertension is associated with a higher risk of developing hypertension compared with normotension. Yet, factors predicting the development of hypertension among prehypertensive people are ill-understood. This prospective cohort study was performed to examine if serum gamma-glutamyltrasferase (GGT) within a normal range can predict the future risk of hypertension among prehypertensive adults. Methods: Study subjects were 293 prehypertensive persons >30-years-of-age who participated in a community-based health survey in 2003 and who were followed up in 2008. Sex-specific quartiles of baseline serum GGT were used to examine association with 5-year hypertension incidence. Results: Baseline serum GGT within normal range predicted the risk of developing hypertension for 5 years only in prehypertensive women. Adjusted relative risks were 1.0, 3.7, 3.6, and 6.0 according to quartiles of baseline serum GGT (P for trend <0.01). This pattern was similarly observed in non-drinkers. However, serum GGT was not associated with incident hypertension in men. Different from serum GGT, baseline serum alanine aminotransferase, another well-known liver enzyme, did not predict the risk of incident hypertension in both genders. Conclusions: Even though baseline serum GGT within normal range strongly predicted the future risk of hypertension, it was observed only in women, Although underlying mechanisms of this association are currently unclear, serum GGT can be used to select a high risk group of hypertension in prehypertensive women.

Objective : The purpose of this study was to evaluate the differences in sagittal spinopelvic alignment between lumbar degenerative spondylolisthesis (DSPL) and degenerative spinal stenosis (DSS). Methods : Seventy patients with DSPL and 72 patients with DSS who were treated with lumbar interbody fusion surgery were included in this study. The following spinopelvic parameters were measured on whole spine lateral radiographs in a standing position : pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis angle (LL), L4-S1 segmental lumbar angle (SLL), thoracic kyphosis (TK), and sagittal vertical axis from the C7 plumb line (SVA). Two groups were subdivided by SVA value, respectively. Normal SVA subgroup and positive SVA subgroup were divided as SVA value (<50 mm and ${\geq}50mm$). Spinopelvic parameters/PI ratios were assessed and compared between the groups. Results : The PI of DSPL was significantly greater than that of DSS (p=0.000). The SVA of DSPL was significantly greater than that of DSS (p=0.001). In sub-group analysis between the positive (34.3%) and normal SVA (65.7%), there were significant differences in LL/PI and SLL/PI (p<0.05) in the DSPL group. In sub-group analysis between the positive (12.5%) and normal SVA (87.5%), there were significant differences in PT/PI, SS/PI, LL/PI and SLL/PI ratios (p<0.05) in the DSS group. Conclusion : Patients with lumbar degenerative spondylolisthesis have the propensity for sagittal imbalance and higher pelvic incidence compared with those with degenerative spinal stenosis. Sagittal imbalance in patients with DSPL is significantly correlated with the loss of lumbar lordosis, especially loss of segmental lumbar lordosis.

Chiefly, painful heel syndrome is observed at old age. Many possible reasons were bursitis, plantar fasciitis, calcaneal periostitis around the calcaneus and achilles tendon. But the exact cause was not clearly identified due to complexity of subcalcaneal pain mechanism. The incidence of calcaneal spur and overweight were significant in painful heel syndrome. Our purpose of this study was analysis of underlyng cause and correlation about bony spur and overweight in painful heel syndrome. The author used incidence of heel spur on painful heel syndrome and body mass index to evaluate overweight. The material is 55 cases of painful heel syndrome patients and 60 cases of control group. Bony spur was one of the cause of painful heel syndrome. Body weight and calcaneal spur was developing factors on painful heel syndrome. And the result was as follows. 1. Spur formation incidence is 35 cases (63.6 %) in painful heel syndrome, 8 cases (13.3%) in normal control group. So, patient's group is significantly high (p<0.01). 2. Body mass index is 26.48 in painful heel syndromes, 21.75 in normal control groups. Overweight above index 27 is 22 cases (40%) in painful heel syndromes, 3 cases (5%) m normal control groups. So, patient's group is significantly high (p<0.01). 3. In painful heel syndrome, tenderness site is 46 cases (83.6%) in medial calcaneal tuberosity, 4 cases (7.3%) in central calcaneal tuberosity, 1 cases (1.8%) in both site. 4. Underlying causes of painful heel syndrome is 19 cases (34.5%) in plantar fasciitis, 16 cases (29.1%) in calcaneal periostitis, 11 cases (20%) in bursitis, 4 cases (7.3%) in tendinitis, 2 cases (3.6%) in entrapment neuropathy.

전립선암의 방사선치료 시 사용되는 세기조절방사선치료와 부피적회전방사선치료시 발생하는 광중성자선량을 측정하여, 암 발생률을 평가하며 기초자료를 제공하고자 하였다. Rando phantom에 중성자 측정용 광자극발광선량계를 복부와 갑상선에 위치시킨 상태에서 발생하는 광중성자선량을 측정하였다. 연구결과 세기조절방사선치료(7 portal)가 부피적회전방사선치료보다 복부와 갑상선 위치에서 모두 높게 측정되었다. ICRP 103의 명목위험계수를 이용하여 암 발생확률을 평가하였을 때, 세기조절방사선치료시 대장과 갑상선의 피폭으로 인한 암발생확률은 1,000명 당 9.9명 이었으며, 부피적회전방사선치료시는 1,000명 당 3.5명이었다. ALARA(As low as reasonably archievable)원칙에 의거하여 방사선치료계획 수립에 있어서 정상장기들의 피폭선량의 최소화를 위한 가이드라인이 되리라 사료된다.

This study examined the incidence of disease and blood biochemical values in 68 Holstein cattle during the a month period after parturition. In order to compare the blood biochemical values, the animals were divided into 2 groups of prepartum and 4 groups of postpartum according to the blood collecting day, respectively. The results compared postpartum with prepartum were obtained as follows : the incidences of displacement of abomasum, culled and retained placenta were 11.8%. 13.2% and 8.8%, respectively. In the normal group(pre and post parturition group), NEFA and bilirubin were increased. Triglyceride and cholesterol were significantly lower than In the pre-parturition group, and total lipid was decreased. In the disease group, displacement of abomasum was significantly higher than in the normal group in the levels of NEFA, triglyceride and bilirubin. Culled was significantly higher than in the normal group in the levels of NEFA, AST and bilirubin. but lower than in the normal group in the levels of triglyceride and cholesterol. Retained placenta was significantly higher than in the normal group in the levels of NEFA and bilirubin, but lower than in the normal group in the levels of triglyceride.

The obesity leads to be the result of the weakening of anatomical structure as well as the gravity effect. And, the obesity interferes with normal sagittal balance and fails to maintain a straight posture with minimal energy. Therefore, the obesity can be an important factor in causing back pain by changing the lumbar lordosis. In this study, we will present an appropriate angle of incidence for obese people to reduce the image distortion of L4, L5 during a general anteroposterior radiography examination. To reduce image distortion according to the change of lordosis, the angle of incidence was applied 9 ° and 21 ° to L4 and L5 vertebra body when obesity and low back pain (LBP) perform the general anteroposterior radiography examination.
