Thirty four patients with a ventricular septal defect, aged 2 months to 24 years [median 2.33 years], had lung biopsies during open heart procedures to assess the degree of pulmonary vascular disease. The patients were divided into two groups according to their age; group 1 - under 2 years of age [15 patients], and group 2- over 2 years of age [19 patients]. The, pathologic change of the pulmonary arterioles was correlated with pre-operative hemodynamic data in 34 patients. There was no significant correlation between the severity of pulmonary vascular disease according to Heath-Edwards classification and the patients age [X2=1.8381, P=0.1751 ]. There was a significant correlation between degree of medial wall thickness and arteriolar diameter and the level of preoperative peak pulmonary artery pressure and peak systemic artery pressure [Pp/Ps]. Also, there was a good correlation between the preoperative pulmonary vascular resistance and systemic vascular resistance [Rp/Rs]. There was no significant correlation between wall thickness and Pp/Ps, and Rp/Rs below the age of 2 years. We conclude that, in patients over 2 years of age, there was a significant correlation between the medial wall thickness of the pulmonary arteriole and elevation of Pp/Ps and Rp/Rs. This is not true in patients under 2 years of age.

Purpose: This study was performed to develop a valid and reliable Korean Patient Classification System for Neonatal care nurses (KPCSN). Methods: The study was conducted in tertiary and general hospitals with 1~2 grade according to nursing fee differentiation policy for NICU (neonatal intensive care unit) nurse staffing. The reliability was evaluated for the classification of 218 patients by 10 nurse managers and 56 staff nurses working in NICUs from 10 hospitals. To verify construct validity, 208 patients were classified and compared for the type of stay, gestational age, birth weight, and current body weight. Nursing time was measured by nurses, nurse managers, and nurse aids. For the calculation of conversion index (total nursing time divided by the KPCSN score), 426 patients were classified using the KPCSN. Data were collected from September 5 to October 28, 2015, and analyzed using t-test, ANOVA, intraclass correlation coefficient, and non-hierarchial cluster analysis. Results: The final KPCSN consisted of 11 nursing categories, 71 nursing activities and 111 criteria. The reliability of the KPCSN was r=.83 (p<.001). The construct validity was established. The KPCSN score was classified into four groups; group $1:{\leq}57points$, group 2: 58~80 points, group 3: 81~108 points, and group $4:{\geq}109points$ in the KPSCN score. The conversion index was calculated as 7.45 minutes/classification score. Conclusion: The KPCSN can be utilized to measure specific and complex nursing demands for infants receiving care in the NICUs.

This paper proposed a sizig system for men's jackets in order to improve the clothing fitness and rain the productivity. The sizing system was classified according to 3 age groups. Figure types were categorized by shoulder angle and body shape. The size interval of the basic dimensions was established at regular intervals centering around their means. Altogether, 15 size charts were developed based on the frequency distribution. Size designating measurements for jackets were height, chest girth and waist girth. Size intervals were 3cm for chest and waist girth, 5m for height, and 2cm for waist and hip girth. Considering the cover factor, charts with a limited number of sizes were suggested with necessary measurements for each figure type of each age group.

This paper proposed the sizing system for womens lower clothes. The sizing system was classified according to 4 body types and 5 age groups. The size intervals of waist girth, hip girth, stature, and slacks length were 3cm, 4cm, 8cm, and 5cm respectively. Frequency distribution analyzed with waist girth, hip girth, and stature showed that the most frequent sizes were 86-100-158 in the fattest-medium length H type, 77-92-158 in the fat-short M type, 68-92-158 in the balanced-long A type, and 65-88-158 in the balanced-medium length A type. The number of the sizes for lower clothes, which had frequencies more than 4∼5%, was 33 and each size was presented with slacks length, skirt length, thigh girth, and knee girth. Also frequency distribution analyzed with waist girth, hip girth, and slacks length showed that the most frequent sizes were 86-100-90 in the fattest-medium length H type, 74-96-90 in the fat-short M type, 68-92-90 in the balanced-long A type, and 65-88-90 in the balanced-medium length A type. The sizing system classified by age group had 21 cases in the early twenties, 21 cases in the late twenties, 18 cases in the early thirties, 16 cases in the late thirties, and 8 cases in the forties. This result will contribute to clothing fitness and efficient production.

The purposes of this study were to provide the fundamental data on elementary school girls' somatotype for their clothing construction by contemplating the stage of physical growth dividing into the period of school age and characterizing the variation of body type according to the school age. The results are as follows : 1. Form the results of one-way variables analysis and multiple comparson test(Duncan's test) classification of the period school age can be divided into 'early grade(1 2 grade)' ' middle grade(3 4 grade)' and 'later grade(5 6 grade)' 2. As the results of analyzing Mean Coefficient of Variation and Standard Deviation graph for direct and indirect measurments and index especially of the Coefficient Variation that explain individual difference of growth the items of height indicates individual difference related with height of lower body of early grade group the items of length individual difference related with length of upper body of later grade group and the items of circumference make little difference. The items of anagle makes pretty higher value that direct measurements and especially in lower angle of chest make a distinctive difference, This fact proves that children's somatotype change from the belly part extruded forwards of early and middle grade to the upper body part slanted slightly forward of later grade.

BACKGROUND/OBJECTIVES: The Dietary Reference Intakes for Koreans (KDRIs) were revised in 2020. Due to the rapidly aging Korean population, special consideration was given to reclassify the KDRI age group categories of older adults. This article examines the evidence for modifying the current KDRI age group ranges of older adults (65-74 and ≥ 75 yrs). SUBJECTS/METHODS: We first reviewed the domestic and international data on the elderly, following which we received expert opinions on age classification from the KDRI Advisory Committee. Finally, the 6th and 7th (2013-2017) Korea National Health and Nutrition Examination Survey (KNHANES) data were used to analyze the nutritional intake statuses by considering the age of older adults. RESULTS: According to the review results of domestic and international data and the inputs received from the expert advisory committee, the minimum age considered for the elderly was maintained at 65 yrs. However, the KNHANES data was analyzed to review whether there was a need to subdivide the later periods. Examining the differences in nutrient intakes by age group through the interaction effect term of the piecewise linear regression model revealed the interaction effect was maximum in the groups divided by 65 yrs (50-64 and 65-80), as compared to the groups divided by 70 yrs (50-69 and 70-80) and 75 yrs (50-74 and 75-80). The mean adequacy ratio was calculated per 1 yr of age, and a 3-yr (age) moving average analysis was performed to examine the change in the trends of overall nutrient intake. However, it was challenging to secure a scientific basis for subdivision into age groups in older adults from the results obtained. CONCLUSIONS: This study could not find any scientific evidence for modifying the KDRI age groups for older adults.

Objectives : The purpose of this study was to investigate the differences in forensic demographic characteristics, interpersonal problems and personality disorder between early and late onset criminal patients with schizophrenia. Methods : The participants included 187 inpatients with schizophrenia who had committed crimes. They filled out the Korean Inventory of Interpersonal Problem Personality Disorder Scales and Psychopathic Personality Inventory-Revised. They were divided into early onset group and late onset group according to onset age of schizophrenia at 26 years old(under 26 versus 26 and older) and forensic demographic characteristics, interpersonal problem and personality disorders including psychopathy were compared between two groups. Results : There were no differences in gender, education years and family history between the two groups. Early onset group was associated with lower age, earlier onset of age and earlier age at the time of the crime. Duration from onset to diagnosis was not different between the two groups. Duration from onset to crime and after diagnosis to crime was shorter in late onset group. There were no differences between the two groups in the interpersonal problems, personality disorder and psychopathic personality evaluation. Conclusion : These results suggested that there may be forensic demographic differences related to crime between early and later onset schizophrenia. Psychiatrists should consider the age at onset of schizophrenia when assessing the risk of violence in patients with schizophrenia. In the future. it will be needed other study of age classification such as admixture analysis.

Objectives: The purpose of this study is to gain the objective indicators for the classification of hypertension by oriental medical pulse diagnosis, through finding out the parameters which can distinguish the pulse of hypertensive patient from that of normal subject, and characterizes the wiry pulse of hypertension. Methods: 30-59 yr, male, 946 healthy volunteers and 35 hypertensive patients were enrolled in this study. All the hypertensive patients were taking medicine to control the blood pressure and the blood pressure of the hypertension group was not statistically different from that of the normal healthy group. Data were acquired using 3 dimensional pulse imaging analyser(DMP-3000, DAEYOMEDI, KOREA) and analysed according to the age bands and the applied pressure levels. Results: 1. RAI/t, w/t and t2/t decreased with the levels of applied pressure and increased with age in the normal healthy group, not in the hypertension group. 2. RAI/t, w/t, t2/t were significantly higher in the hypertension group than the normal healthy group in the 30-age band, and elasticity coefficient was higher in the hypertension group than the normal healthy group in the 40-age band. 3. Researches on the patients without hypotensive agents are needed to figure out whether these parameters are the components of hypertensive wiry pulse. Conclusions: Analysing the radial pulse at 5 applied pressure levels using 3 dimensional pulse imaging analyser may be useful to differentiate the pulses of the hypertensive patients from those of the normal subjects, and characterize the hypertension.
