Osteoporosis in gastric cancer patients is often overlooked or even neglected despite its high prevalence in these patients. Considering that old age, malnutrition, chronic disease, chemotherapy, decreased body mass index and gastrectomy are independent risk factors for osteoporosis, it is reasonable that the prevalence of osteoporosis in gastric cancer patients would be high. Many surviving patients suffer from back pain and pathological fractures, which are related to osteoporosis. Fractures have obvious associated morbidities, negative impact on quality of life, and impose both direct and indirect costs. In the era of a >55.6% 5-year survival rate of gastric cancer and increased longevity in gastric cancer patients, it is very important to eliminate common sequelae such as osteoporosis. Fortunately, the diagnosis of osteoporosis is well established and many therapeutic agents have been shown to be effective and safe not only in postmenopausal females but also in elderly males. Recently, effective treatments of gastric cancer patients with osteoporosis using bisphosphonates, which are commonly used in postmenopausal woman, were reported.

This study was performed to investigate the temperature-dependent development, longevity and oviposition of an indigenous larval parasitoid, Meteorus pulchricornis, on tobacco cutworm, Spodoptera litura. M. pulchricornis were reared at nine constant temperatures between 15 and $35^{\circ}C$. The developmental times of each three developmental stage decreased from 38.7 to 16.3 d between 15 and $30^{\circ}C$. However, M. pulchricornis showed longer developmental time at $32.5^{\circ}C$ (9.5, 7.7 and 17.2 days for each three developmental stage) than at $30^{\circ}C$ (8.9, 7.3 and 16.3 days for each three developmental stage). Immature M. pulchricornis could not develop any more at $35^{\circ}C$. The lower developmental threshold estimated by linear regression equation for the egg to cocoon, cocoon to adult emergence and egg to adult emergence were 5.1, 4.6 and $4.5^{\circ}C$. The thermal constant for each of the three stages were 217.2, 176.2 and 403.8 degree-days, respectively. When no food or 50% honey solution as a food source is provided for M. pulchricornis, the parasitoid survived for 8.3 and 55.9 days at $25^{\circ}C$, respectively. M. pulchricornis females laid 5.2 eggs daily and total of 131.6 eggs at $25^{\circ}C$ until it died. Peak age-specific fecundity was observed on $14^{th}$ day (9.6 cocoons) after parasitoid emergence and gradually decreased thereafter.

This paper proposes an empirical evidence about contextual factors which determine perceived business performances of small firms resulted from IT investment. In this paper, small firms are defined as firms of which total employees are below fifty. These small firms account for 95% of total number of private companies in Korea. We used a perceived IT performance model based on Balanced Scorecard framework to evaluate IT performance of small firms. And data were collected by Web and e-mail survey method with multiple screening. Statistical results show that business performance of small firms are differentiated in terms of firm size, location, longevity, age of owner, education level of owner, while industry sector, profitability, sex of owner don't make significant differences.

This study was carried out to calculate working life expectancy and its potential gains according to the degree of reduction in the specific causes of death. It sought to ascertain what potential gains in labor force longevity might be reasonably achieved through efforts to reduce mortality from injuries and poisoning, diseases of circulatory system, neoplasms and the other causes of death. The data were drawn from the three sources such as "The 1982 Causes of Death Statistics," "Abridged Life Table for Korea 1978~'79" and "The 1982 annual Report of Economically Active Population" issued by Economic Planning Board. Analytical tools used in this study were the cause-deleted life table and the Wolfbein Wool's working life table method. Partial life expectancy was adopted as an index of this study, This application will be widely used as a good demographic tool for analyzing the dynamics of labor force and causes of death. Some of the findings are summerized as follows. 1. Partial life expectancies from initial age 15, 25, and 45 respectively to terminal age 65 are 44.86, 35.59 and 17.41 year in life expectancy itself, 37.08, 32.83 and 15.21 year in working life expectancy, 7.78, 2.76 and 2.20 years in inactive life years. 2. Potential gains in working expectancy from initial age 15, 25 and 45 to terminal age 65 by the complete elimination of the specific causes of death are 1.36, 0.94 and 0.27 years in injuries and poisoning, 0.88, 0.83 and 0.54 years in diseases of circulatory system, 0.56, 0.54 and 0.37 years in neoplasms, 1.13, 1.02 and 0.58 years in the other causes of death. The relationship between degree of reduction in causes of death and potential gains in working life years is in direct proportion. The prime orders of reduction effectiveness in age groups by the causes of death are injuries and poisoning in age 15-24, the other causes of death in age 25-49 and diseases of circulatory system in age 50 and over. 3. If it were possible to reduce 25%, 50% and 75% in mortality condition 1978~'79, the average length of working life would be 38.08, 39.13 and 40.17 years in age 15, and 33.68, 34.57 and 35.44 years in age 25, and 15.67, 16.14 and 16.63 years in age 45.

기존 보고된 귤응애 온도발육자료를 이용하여 온도발육 관련 매개변수 값을 추정하고 개체군 동태 추정에 필요한 행렬모형을 작성하였다. 귤응애 발육영점온도는 알 $8.4^{\circ}C$, 유충 $9.9^{\circ}C$, 제 1약충 $9.2^{\circ}C$, 제 2약충 $10.9^{\circ}C$ 이었으며, 발육완료에 필요한 적산온도는 각각 113.6, 29.1, 29.8, 33.4일도(DD)로 추정되었다. 귤응애 각 발육단계별 비선형 발육모형을 수립하였으며 또한 산란모형 작성에 필요한 온도별 총산란수 모형, 연령별 누적산란율모형, 연령별 생존율 모형의 매개변수 값을 각각 추정하였다. 귤응애 연령군을 알, 유충, 제 1약충, 제 2약충, 성충 등 5단계로 구분하여 행렬모형을 작성하였다. 전환행렬의 구성요소인 다음 발육단계로 전이확률 또는 잔존확률은 각 발육단계의 발육률 함수를 이용하였다. 또한 성충의 산란계수는 해당온도에서 성충수명 완료율과 총산란수의 곱으로 추정하였다. 수립된 행렬모형의 포장적합 능력을 평가하기 위하여 실제 감귤원에서 조사된 귤응애 실측밀도와 행렬모형으로 추정한 개체군 밀도를 비교하였다(2004년). 계절 초기 저온기와 계절중후기 고온기에 모형결과를 실측치와 비교한 결과 알 및 성충 개체군은 계절초 및 중후기 모두 약 30일까지 큰 차이가 없었다. 따라서 본 개발된 행렬모형을 이용하여 30일 내외의 단기간 동안 귤응애의 개체군밀도 증가를 예측할 수 있을 것으로 기대되었다.

The purpose of this study was to measure circumference of four body parts of each Sasang groups with Bioelectrical Impedance Analysis (BIA), and evaluate its usefulness for Sasang type diagnostic test. We obtained the circumference measures of neck (CN), chest (CC), waist (CW), and hip (CH) of 91 college students using BIA and standardized by sex and age. The validity of Sasang group prediction with CC was evaluated. The Tae-Eum group (104.87${\pm}$5.19, 108.47${\pm}$4.96, 116.00${\pm}$9.39, 110.4${\pm}$5.29. neck, chest, waist and hip, respectively) has significantly (p<0.001) bigger circumferences than So-Yang (97.79${\pm}$3.82, 100.02${\pm}$4.21, 101.02${\pm}$7.88, 101.95${\pm}$4.06) and So-Eum (95.63${\pm}$4.67, 96.93${\pm}$4.80, 97.63${\pm}$7.72, 99.86${\pm}$4.40) groups at very four measures. Discriminant functions with CC can be used for Tae-Eum Sasang type diagnostic test with 91.2% of overall Percentage Correctly Predicted (PCP). Tae-Eum type-specific sensitivity was 73.3% and Tae-Eum type-specific specificity was 94.7%. The strength and weakness of measurement and standardization methods for Sasang type diagnostic test, and the methods for the standardization of physical traits with sex and age were discussed. Our study showed distinctive physical features of Tae-Eum type and the usefulness of BIA for the Sasang type diagnosis.

Purpose: Generally, aspirin is used as a protective agent against thrombogenic phenomenon after pulmonary valve replacement (PVR) using a bioprosthetic valve. However, the appropriate duration of aspirin use is unclear. We analyzed the impact of postoperative duration of aspirin use on the longevity of bioprosthetic pulmonary valves in patients who underwent repair for congenital heart diseases. Methods: We retrospectively reviewed the clinical data of 137 patients who underwent PVR using a bioprosthetic valve between January 2000 and December 2003. Among these patients, 89 were included in our study and divided into groups I (${\leq}12$ months) and II (>12 months) according to duration of aspirin use. We analyzed echocardiographic data from 9 to 11 years after PVR. Pulmonary vale stenosis and regurgitation were classified as mild, moderate, or severe. Results: The 89 patients consisted of 53 males and 36 females. Their mean age was $14.3{\pm}8.9$ years (range, 2.6-48 years) and body weight was $37.6{\pm}14.7kg$ (range, 14-72 kg). The postoperative duration of aspirin use was $7.3{\pm}2.9$ months in group I and $32.8{\pm}28.4$ months in group II. However, no significant difference in sex ratio, age, body weight, type of bioprosthetic valve, and number of early redo-PVRs. In the comparison of echocardiographic data about 10 years later, no significant difference in pulmonary valve function was found. The overall freedom rate from redo-PVR at 10 years showed no significant difference (P=0.498). Conclusion: Our results indicated no benefit from long-term aspirin medication (>6 months) in patients who underwent PVR with a bioprosthetic valve.

본 연구에서는 OECD 가입국들의 국제비교의 관점에서 연금운용 및 자산축적의 과정을 통한 한국의 노년기 자산관리의 실태를 분석하고 그에 따른 정책적 시사점을 논의하였다. OECD 가입국 중 최하위에 위치한 노년기의 소득대체율은 국민연금을 비롯한 공적연금 체계, 퇴직연금의 기반 미흡, 그리고 개인연금 및 개인 금융자산 축적의 미비에 근거하고 있다. 2060년 기금자산의 고갈에 직면한 국민연금의 기금운용은 글로벌 주식투자의 비중이 아직까지 선진국에 비해 낮은 추세이고 낮은 소득상한선 설정 등 기금운용상의 문제점이 노출되고 있다. 이에 따라 국민연금 기금운용상의 전문성이 더욱 강화되어야 하고 소득상한선 확대 및 갹출료 인상이 병행하여 추진되어야 할 것으로 판단된다. 2011년 도입된 퇴직연금은 완전강제화 미실시로 인해 아직까지 선진국들에 비해 낮은 소득대체율의 원인으로 지적될 수 있으며 퇴직연금의 자산운용구성 또한 단기 금융자산의 비중이 지나치게 높아 수익률 제고가 어렵다. 이에 따라 퇴직연금의 완전강제화와 더불어 운용자산의 전문성 제고가 시급한 과제로 지적될 수 있다. 개인의 자발적인 노후대비를 위한 개인연금 및 가계금융자산의 축적확대는 공적연금에 준하는 세제상의 지원이 뒷받침될 필요가 있다고 할 수 있다. 마지막으로 최근까지 폭발적 성장세를 구가하고 있는 주택연금의 안정적 추진을 위해서는 현재 정부가 모든 예상손실을 부담하는 비대칭적 구조에서 탈피하여 점차 시장에 의한 가격위험, 장수위험 등의 위험분산기법 추진을 통한 위험분담이 바람직할 것으로 판단된다.

The purposes of this study were to estimate nutritional intakes of the long-lived elderly and to obtain the data for establishing dietary guidelines that may be recommended for the general population for the sake of longevity. The subjects of the study were 300 elederly people of age over 85 years living in Kyungpook Sung-Ju area who had no problem in daily living. Four times of food consumption survey were carried out seasonally by the repeated 24-hr recall method for one year. Mean daily energy intakes and RDA percentage of energy intakes of the male and female subjects were estimated as 1222 kcal(67.9%) and 1047 kcal(65.4%) respectively. Mean daily intakes of nutrients were estimated as 38.3g for protein, 287mg for calcium, 5.8mg for iron, 314R.E. for vitamin A, 0.6mg for vitamin B1 and 0.43mg for vitamin B2 The mean RDA percentages of nutrients intake were 64.4% and 59.8% for protein in male and female, 39.8% for Ca, 48.3% for Fe, 44.9% for vitamin A, 60% for vitamin B1, and 35.8% for B2. The average PFC ratio of energy-yielding nutrients throughout the year in male and female were 15.1 : 15.2 : 69.7 and 13.8 : 13.2 : 73.0 respectively. The mean daily intakes of energy and most of nutreints were significantly high in winter season. The contribution of plant food sources to nutrient intakes were over 60% for protein and fat, 50% for calcium, and 70% for iron. Long-lived elderly people an Sung-Ju, Kyungpook showed considerably smaller physiques compared to the avergae Korean elderly, however their average BMI fell in normal range. The subjects were consuming much less energy and nutrients compared to the present Korean RDA for the elderly over age 75. The subject showed relatively good health state in spite of low intakes of energy and nutrients. Therefore it seems to be necessary to establish a set of new RDA for the elderly over age 8.5.
