목적: 약년자와 고령자에서 발생하는 위암의 차이점에 관한 연구는 이전부터 있어왔지만, 최근 한국인의 평균 수명이 연장되면서 이에 따른 약년자 군과 고령자 군을 새롭게 분류해야할 필요가 제기되었다. 약년자에서 발생하는 위암은 진단 시 간파되기 쉽고, 고령자 위암의 경우 동반질환으로 인해 수술 전후의 위험도를 증가시키는 것으로 알려져 왔다. 저자들은 약년자 군과 고령자 군에서 발생한 위암에서 각각의 임상병리학적 특성과 예후에 관하여 알아보고자 하였다. 대상 및 방법: 위암 환자를 나이에 따라 35세 이하의 약년자 군 31명과 75세 이상의 고령자 군 49명으로 분류하고 성비, 발생위치, 조직학적 분류, 병기, 수술방법, 평균생존율 등의 임상병리학적 특성을 비교하였다. 결과: 약년자 군에서 미분화 선암과 미만형의 발생률이 가장 높았으며, 고령자 군에서는 미분화와 중등도 분화 선암, 장형의 발생률이 가장 높은 것으로 관찰되었다. 그 외 두 군 간의 수술 방법의 차이나 술 후 합병증 및 수술 전후의 사망률 등의 의미있는 임상적 차이는 관찰되지 않았다. 또한, 두 군 간의 생존율 차이도 관찰되지 않았다. 결론: 약령자와 고령자 두 군 간에 임상병리학적이나 생존율의 차이를 보이지 않았고, 두 군 간 수술방법과 근치도에서 차이가 없는 수술이 시도된 결과 고령자 군에서 약년자 군에 비해 생존율 저하를 보이지 많았다. 따라서 고령 환자에서 발생한 위암의 치료 시 보다 적극적 수술 치료가 필요할 것으로 생각된다.

Objective : The incidence of aneurysmal subarachnoid hemorrhage has been increasing. At the same time, surgical results for elderly patients are unsatisfactory and no guidelines of treatment are available. We carried out a study comparing variable factors and surgical results between young and old age groups to find ways to improve prognosis. Methods : A retrospective study was carried out on 754 patients who were operated on between 1990 and 2004 by the same surgeon in our hospital. The patients were divided into seven groups according to age : 93 patients below 40 years of age [Group I], 419 patients aged $40{\sim}59$ [Group II], 115 patients aged $60{\sim}64$ [Group III], 82 patients aged $65{\sim}69$ [Group IV], 28 patients aged $70{\sim}74$ [Group V], 12 patients aged $75{\sim}79$ [Group VI] and 5 patients over the age of 80 [Group VII]. We then checked their medical history, Fisher's grade, Hunt-Hess grade, postoperative complications, and Glasgow Outcome Scale. Results : Age was not a statistically significant factor among patients below 70 years of age [P $value{\ge}0.05$]. But for those aged 70 and older, the age factor had a statistical value [P $value{\le}0.001$]. In addition, there was a close correlation between Hunt-Hess grade IV and V patients, and those with vasospasm, and hydrocephalus after surgery, with poor prognosis in elderly patients as well as young patients [P $value{\le}0.001$]. Conclusion : Advanced age [under the age of 70] dose not precluded adequate surgical treatment in patient with AN SAH, and we should be also alert to preventable causes of delayed neurological deterioration for improving the outcome in all elderly groups.

The author studied on the dental arch widths and lengths and height of palates at 3 groups of dentition: mixed dentition, early permanent dentition, young adult, having normal occlusion and dentition. The models of the 336 maxillary and mandibular case, made from alginate-base hydrocolloid impressions were measured and analyzed statistically. The result as follows; 1. The upper intercanine width increased between the mixed dentition group and early permanent dentition group but there was no change in the young adult group in both sexes. The lower intercanine width increased between the mixed dentition group and early permanent dention group in the male. 2. The upper and lower 1st bimolar width increased slightly with age in the male but there was no change in the female. 3, The sex difference found in this study was one of absolute size, the female being slightly smaller than the male in the early permanent dentition group and young adult. 4. The arch length had no notable sexual differences and decreased between the mixed dentition group and early permanent dentition group. There was no change in the arch length in the young adult. 5. The height of palate increased gradually with age.

Two hundreds of female aged 19 years old and up were recruited to evaluate the postural changes and bilateral variation of asymmetry over age. To find out the differences among the age group, subjects were classified into 5 groups, early young age(19-29), late young age(30-39), early middle age(40-49), late middle age(50-59), and old age(60-). 35 body measurements were taken by the 3-D body scanner which allowed us to take measurements which cannot be measured using traditional methods, including the shape of a cross section, slice area surface are, and volume. Bilateral variations were observed as a function of age; Depth of scapular point level, scapular point to center back, and blade angle. Postural change of anterior cervical angle, upper anterior thoracic angle, upper posterior thoracic angle, posterior cervical angle, and center back/center front ratio were also exhibited. In each measurements, subjects were classified into normal, and abnormal group. Percentiles of abnormal in shoulder line angle, blade angle, neck point $\∼$ acromial point $\∼$ scapular point, posterior cervical angle, and upper posterior thoracic angle were increased over age group. The upper body of lateral view was classified into 3 types of posture based on the previous research; straight, erect(leaning back), and stooped(bent forward). The percentiles of subjects who have straight postures were decreased as a function of age, but those of stooped postures were increased. Subjects who have erect postures did not so. The stooped posture group shows the big cervical fossa angle, anterior cervical angle, posterior cervical angle, upper posterior thoracic angle, and the small upper anterior thoracic angle comparing to the straight and erect posture group. These results could be apply for clothing construction reflecting the changes in back, shoulder, neck, and the bilateral asymmetry according to the target age group.

Objectives: This study aimed to investigate factors influencing suicidal ideation among Korean adults. Methods: Cross-sectional data from the fifth Korea National Health and Nutritional Examination Survey conducted in 2012 were analyzed in this study. The subjects were categorized into three groups by subjects' age(defined as young adults(20-39), middle-aged adults(40-59), and the elderly(60 or more). Data were analyzed by frequency, Chi-square test and multiple logistic regression using SPSS 18.0. Results: The factors influencing suicidal ideation were different among three age groups. The influencing factors were (1) gender, marital status, household income, perceived stress and depression in the young adult group, (2) household income, perceived health status, perceived stress and depression in the middle-aged group, (3) gender, regular physical activity, smoking, perceived health status, perceived stress and depression in the elderly group. Conclusions: The health education considering the characteristics of each age group should be developed and applied to prevent adults' suicidal ideation because the factors influencing suicidal ideation were revealed differently between the age groups.

A study on the change of cardiothoracic ratio by age calculated from photofluorography film of chest in a total of the 8,115 insureds was undertaken. The results were as follows: 1. The incidence of cardiothoracic ratio of high value increased gradually with age. 2. At the same build, the average cardiothoracic ratio increased gradually with age. 3. Larger the build index was, the incidence of higher cardiothoracic ratio increased. 4. It seemed that the change of cardiothoracic ratio by age was influenced mainly by age and build(the change of build by age) from $18{\sim}19$ to $40{\sim}49$ age group and by age itself in $50{\sim}59$ age group and over. 5. The average cardiothoracic ratio of $30{\sim}39$ age group in male or female was approximate to that of all ages group respectively.

Purpose: Injury is a leading cause of morbidity and mortality for children. As an injury prevention measure, the differences in external causes of severe pediatric injuries based on ICECI were analyzed according to age groups. Methods: A retrospective study was performed for pediatric patients under 15 years of age, who had been admitted to the emergency department with severe injuries from January 1998 to December 2004. The external causes of injury were investigated according to the ICECI: intent, mechanisms, places of occurrence, objects/substances producing injury, and related activities. The patients were divided into four groups based on age: infant (<0 year), toddler (1~4 years), preschool age (5~8 years), and school age (9~15 years). Results: The injury mechanisms, the places of occurrence and the related objects/substances vary with the age groups. The most common subtype of traffic accidents was pedestrian injury in pre-school age group. Falls most frequently occurred in the toddler group. But falls from a height of less than l meter height (6 patients) occurred only in the infant group. The most common place of occurrence in the infant group was the home, and that of other groups was the road. The related objects/substances for falls, for example, household furnitures and playground equipment depended on the age group. Conclusion: The age-group specific characteristics of severe pediatric injury were analyzed successfully through the ICECI. Therefore, when establishing a plan for the prevention of pediatric injury, consideration must be given to the differences in the external causes of injuries according to age group.

The purpose of this study is to investigate how the shape of the lower body influences an individuals' ease in fitting skirts. Subjects in this study consisted of 188 adult females categorized into two groups(the first group were subjects 18∼33 years of age and the second group 34∼59 years of age), whose measurements were taken and then compared between the two groups. The subjects were also categorized into 5 different lower body types. The following are the results; (1) The comparative analysis of the ease from the two a9e groups showed a bigger value of waist girth in the young age group. And thereverse results were found when measuring hip firth. (2) The correlation analysis between the ease and the anthropometric data showed a weak statistical correlation in the older group, and showed no statistical correlation in the younger group. However, there was correlation between the ease and the body measurements as well as between the differences of waist girth and hip girth. (3) The most appropriate average ease of skirt in the young age group was 1.03 cm for waist and 5.71 cm for hip; the most appropriate average ease of skirt in the older age group was -0.76 cm at the waist and 4.10 cm at the hip. (4) Analysis of variance with a special emphasis on the ease of waist girth and hip girth according to the anthropometric data of the lower body revealed a statistically significant correlation.
