  • Morphological difference of the renal glomerulus at different age groups have been studied in young (three month-old), adult (twelve month-old) and old (thirty month-old) Fisher strain 344 rats. Pieces of the tissues were taken from renal corticies prefixed with 2.5% glutaraldehyde-1.5% paraformaldehyde (0.1 M Millonig's phosphate buffer, pH 7.3), following by post-fixation with 1% osmium tetroxide (0.1 M Millonig's phosphate buffer, pH 7.3) and embedded within Araldite. The ultrathin sections contrasted with uranyl acetate and lead citrate were observed under a JEM 100CX electron microscope. The mean thickness of glomerular basal lamina and Bowman's capsule were determined by measuring the thinnest portion of basal lamina, and by taking the average of 50 readings from electron micrographs at different ages. The numerical changes of the slit pores were compared based upon the numbers over the length of 10um of glomerular basal lamina. The results were as follow: 1. The thickness of glomerular basal lamina is increased during aging; 140.4 nm in young rats, 270.0 nm in adult ones, and 437.8 nm in old ones. 2. The thickness of basal lamina of parietal cells of Bowman's capsule is 187.5 nm in young rats, 914.0 nm in adult ones, and 2850.0 nm in old ones. 3. The numbers of the slit pores of basal lamina are reduced during aging, 30.3 slit pores/$10{\mu}m$ in adult ones, and 24.2 slit pores/$10{\mu}m$ in old ones. 4. Accumulation of dense intracytoplasmic filamentous material in the parietal cells of Bowman's capsule is increased in the vicinity of the basal lamina during aging. The proximal tubule-like epithelial cell in Bowman's capsule is observed at one glomerulus in a young rat. 5. The endothelial cells are edematous and form balloon-like structure protruding into capillary lumen in young and old rats. 6. Cytoplasm of the podocyte shows a variety of alteration during aging, such as swelling of mitochondria and of endoplasmic reticulum, and increase of microtubules, microfilaments, lysosomes and lamellated myelin structures, etc. Accumulation of dense intracytoplasmic material in the foot processes is increased in the vicinity of the basal lamina during aging. The podocytic membrane-like structures are seen in young and o]d rats. 7. The mesangial matrices and mesangial cells are increased during aging, and slight swelling of endoplasmic reticulum and Golgi cisternae in young and old rats.

  • The objective of the study was to obtain standard sizes of body of the high school girls for designing clothes and developing pattern grading of clothes. In 1972, 342 students, selected by the stratified cluster random sampling method, at three high schools in Seoul were measured on forty-one items by the R. Martin method. Statistical techniques of mean, standard deviation, coefficient variable, maximum and minimum, range, t-test were utilized to analyze the data. The findings of the study were as follows ; 1. No differences were found among the age groups in the all measured variables. 2. Stature, bust girth, hip girth, acromion width, posterior waist girth/stature ratio of the high school girls were significantly smaller than those sizes of adult women. This result implies that those sizes will be increased as the students grow up. But upper arm girth, upper arm girth/bust girth ratio, and thigh girth/bust girth ratio were bigger than those sizes of adult women. Waist girth, thigh girth, total head height/stature ratio, acromion width/stature ratio, and foot length/stature ratio were nearly similiar to those of adult women. 3. According to the result of t-test, waist breadth, spinailiaca anterior height/stature ratio, thigh girth/bust girth ratio, and thigh/hip girth ratio of the 15 year old group were significantly different from those of the 16 year old group at the level of 0.05. Bust girth, weight, foot breadth, posterior croth length, and cervical height/stature ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.01. Hip girth, upper arm girth, waist breadth/stature ratio, and neck base girth/bust girth ratio of the 16 year old group were significantly different from those of the 17 year old group at the level of 0.05.

  • Due to global economy recession with low oil price, Korea has stepped into a stage of sluggish development, and the unemployment has become a major issue. Hence, we study various risk factors influencing on unemployment using the Korean labor and income panel data of 2014. We first divide the adult life cycle into three categories, such as young adult, adult, and old adult. Then we consider demographic variables, occupational variables and health related variables as risk factors. The decision tree models have shown that education and gender are the most important factors respectively in young adult group and in adult group. Gender, health status, and education are influential factors in old adult group.

  • The purpose of this study was to investigate the effects of adult attachment, responsibility attribution, and self - esteem of adult women on psychological violence in intimate relationships. For the study, we analyzed the data of 137 women collected using self - report questionnaires. The results of the study showed that the higher the level of Age(over 36 years old), love experience(more than 4 times) and attribution of responsibility, the higher the victim of psychological violence. The higher the age (over 36 years old), the love experience(more than 4 times) and adult attachment, the higher the harms of psychological violence. On the other hand, self-esteem showed no effect. Therefore, efforts should be made to reduce the psychological violence of adult women by developing intervention strategies for secure adult attachment enhancement and hostile attribution reduction.

  • This study was carried out to find out the acquisition effect by measurement periods of adult learners learning through English pattern practice. The subjects of this study were divided into adult learner groups including the learners in their 40s and those who were over 65 and the child group who were 8 years old as a comparative group. After the subjects had a pre-test at first, person agreement and tense were instructed though English pattern practice and right after that, they had a post-test. Then 4 weeks later, they had a delayed test. As a result, the acquisition result of adult learners learning though English pattern practice showed the largest rise by those in their 40s and the learners of those over 65. However the adult learners aged over 65 showed the largest drop in delayed test of the reading comprehension. Based on these results, it is necessary to develop teaching method for adult learners in consideration of their characters and weak points.

  • The serotonin-immunoreactive (5-HTil neurons have been investigated in the brains of lanra, pupa and adult from Pieris ropae. There are ca. 54 5-HTi neurons in 5-instar larva, ca. 20 in 2-dav-old pupa and ca. 118 in 1-day-old adult, respectively. Most of these 5-HTi neurons are interneurons, but efferent and afferent 5-HTi neurons were also observed. Most of the 5-HTi neurons project into the central neuropils of postembrvonic brains. The larval brain contains abundant 5-HTi processes in the central neuropils, including those in three cerebral commissures. But in the pupal brain the 5-HTi processes are restricted in small numbers to the given regions of central neuropil. The adult brain contains a large number of 5-HTi processes in mushroom body, central body complex, lateral protocerebrum, protocerebral bridge, antennal lobe, and tritocerebral and suboesophageal neuropils. However, the 5-HTi processes are not found in the optic lobe of the brains. One prominent feature of the 5-HTi fibers in the postembrvonic brains is the fact that they are greatly arborized.

  • 1. Objectives The purpose of this study lies on the objectification of the Sasang Constitutional diagnosis. This study was analyzing the constitutional characteristic of adult men voices by PSSC-2004. 2. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 231 adult men voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 231 was composed with 5 Taeyangins, 32 Soyangins, 102 Taeumins and 92 Soeumins. The under 55 years old group was composed with 4 Taeyangins, 23 Soyangins, 83 Taeumins and 77 Soeumins. The over 55 year-old group was composed with 1 Taeyangin, 9 Soyangins, 19 Taeumins and 15 Soeumins. 3. Results 1) In total group, the Soeumin's mean value of center pitch(4)$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.034). 2) In total group, the Soeumin's group 3 APQ was significantly low compared with the others (P=0.042). 3) In under 55 year-old group, the Soeumin's center value of center pitch 4$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.025) 4) In over 55 year-old group, no statistical significance was found between the Taeyangin, Soyangin, Taeumin and Soeumin. 4. Conclusions In under 55 year-old group, Soeumin's voice showed high pitched sound (clearness) at the low frequency (1000-2000Hz). In over 55 year-old group, there is no significant differences. This fits in with that 'Soeumin's voice is 'Yu-tone' born by 'Shang-tone', very short and high.' 'Yu-tone' corresponds to 'Ra' and witch is highest among Gong, Shang, Gao, Chi and Yu. This is related with the appearance that the Soeumin's voice is weak, thin and high tone. Therefore it is supposed that Soeumin adult men's voices are thick, and there are vibrations of the ending. It is accepted one of the Soeumin's characters like as a mild tremor of limbs and deep breath caused by Soeumin's Qi-deficiency. This outcome accords with the theory that Soeumin's Qi is less than the Other constitutions.

  • Objectives The purpose of this study was to objectify the diagnosis of Sasang constitution. It was analyzed the adult female voices into 44 factors with PSSC-2004. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 217 adult women voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 216 was composed with 8 Taeyangins, 60 Soyangins, 66 Taeumins and 83 Soeumins. The under 55 year-old group was composed with 6 Taeyangins, 53 Soyangins, 55 Taeumins and 76 Soeumins. The over 55 year-old group was composed with 2 Taeyangins, 7 Soyangins, 11 Taeumins and 7 Soeumins. Results 1. In total group and under 55 year-old one, Soeumin's center pitch were significantly high compared with the others(P=0.005)(P=0.019). It was significant for distinction between Taeumin and Soeumin at the result of post mortem. 2. In over 55 year-old group, Soeumin's center freq.(total) and center freq.(1) were significantly high compared with the others(P=0.024)(P=0.016). In under 55 year-old group, Soeumin's center freq.(4) was significantly high(P=0.025). While Taeumin's center freq.(3) in under 55 year-old group and center freq.(4) in over 55 year-old group were significantly high(P=0.049)(P=0.043). 3. In over 55 year-old group, Soeumin's APQ(center), APQ(2/5), APQ(3/5), APQ(4/5) and APQ(2/3) were significantly high compared with the others. It was significant for distinction between Taeumin and Soeumin at the result of post mortem(P=0.004) (P=0.003) (P=0.004) (P=0.013) (P=0.004). 4. In over 55 year-old group, Soeumin's APQ(1/3), APQ(1/2), APQ(2/2) and zeroover APQ were significantly high compared with the others (P=0.013) (P=0.003) (P=0.008) (P=0.012). 5. In over 55 year-old group, Taeyangin's octave 3 shimmer was significantly high compared with the others(P=0.000). 6. In under 55 year-old group, Taeyangin's total energy was significantly high compared with the others(P=0.040). 7. In under 55 year-old group, Taeyangin's zeroover energy sum was significantly high compared with the others(P=0.038). Conclusions From above result, there is the possibility of efficiency standard guide for constitutional diagnosis by analyzation of the voices.
