In this study, I analyzed the measurement data of the early 20s male who are emphasizing the importance of good clothes in the fashion of body-contact clothes. Through this, I tried to provide basic data necessary for making clothing for early 20s male. Using data from Size Korea's 7th Human Body Survey, 588 people aged 20-25 years were analyzed and classified into four types. Type 1 have a thick and short body, narrow ankle and calf, thin legs. And the hip is not sagged, and height is a little short. So I named it 'short & thick body with bird legs'. Type 2 have a broad shoulder, slim and long body, and no sagging shoulders. So I named it 'slim inverted triangular figure'. Type 3 have a small height, thin and short body, and a thick ankle and calf. So I named it 'short & thin body with thick legs'. Type 4 have a tall height, narrow shoulder, and sagging hip and shoulders. So I named it 'Long triangle'. In order to improve fit of body-contact clothes reflecting the trend of men's wear in recent years, it is necessary to develop clothing prototypes by body type. 20s have the most ideal body shape after completion of growth, but differences in the length, thickness, and thickness of the trunk. This is reflected in the apparel pattern system, and it can be expected to increase consumers' satisfaction if they are used to make excellent ready-to-wear patterns.

For design of early childhood children's footwear, this study was to analyze the properties of their foot. This study was performed in 200 male and 200 female early childhood children from 3 and 6 years old lived in susan urban area. There were measured 17 items of the foot and calculated 4 indexs for analysis. The result was as follows; 1 The growth rate differs from the sites of a foot. According to the growth of age, early childhood children's foot are more slender. 2. The average of foot print angle is $15~27^{\circ}$ and it is flat. Among the age groups, the numbers of 4 kinds of foot print angle are different siginificantly. 3. The average of metatarso phalanx angle is $174~178^{\circ}$ that is higher than adults'. 4. There are no significant difference between male children's foot and female childen's one except tarsal circumference and tarsal height. Tarsal part of male children is higher and ticket than female children's. 5. Because some of 3~6 age groups belong to the one foot length group, we should consider the age properties of foot in order to design footwears. When the size of footwear is divided by only foot length, the ranges of another measurements are larger than the range of foot length.

To evaluate the periodontal status of Korean adults, 3,988 adults(20-69 years old) who lived in Kwangju, Chonnam, Taegu, and Kyungbuk districts were periodontally examined by plaque index(PI), calculus index(CI), gingival index(GI), periodontal disease index (PDI), and papillary bleeding index(PBI). The periodontal examination charts were grouped according to age and sex. And subsequently 200 periodontal examination charts in each age group were randomly selected according to sex. The differences of the indices among age groups and those between male and female in each age group were statistically analyzed by Chi-Square test. In PI, CI, GI, PDI, and PBI, there was no statistical significance in the difference between male and female in each age group(p>0.05). In male, PI of 60s age group($1.44{\pm}0.68$) was significantly higher than that of any age group(p<0.05), and in female PI of 20s age group($0.86{\pm}0.39$) was significantly lower than that of any other age group(p<0.05). CI of 60s age group in both male($1.67{\pm}0.70$) and female($1.63{\pm}0.91$) was significantly higher than that of any age group(p<0.05). GI of 20s age group in both male($0.85{\pm}0.66$) and female($0.67{\pm}0.60$) was significantly lower and GI of 60s age group in both male($1.37{\pm}0.60$) and female($1.44{\pm}0.84$) was higher than that of any age group(p<0.05). PDI in male was the lowest in 20s age group($0.70{\pm}0.73$), and was the highest in 60s age group($4.93{\pm}1.96$) (p<0.05). In female PDI of 20s age group($0.71{\pm}0.74$) was significantly lower than that of any age group(p<0.05). In male PBI of 20s age group($0.38{\pm}0.31$) was significantly lower than that of any age group(p<0.001). PBI in female was the lowest in 20s age group($0.35{\pm}0.30$) (p<0.001), and was the highest in 60s age group($1.09{\pm}0.76$) (p<0.05). The data insist that all the young populations of 20s age group should be interested in routine check for early diagnosis and prevention of periodontal disease, and a special education program of periodontal health care for young generation must be prepared, and the periodic recall check system for periodontal examination of middle age group must be supported by government.

This paper compares the syllable structure of French and Korean analyzing the speech data of these two languages recorded during the actual speech. Reference to the syllable structure of French is made from F. Wioland's research data. As for the Korean data, the primary data are drawn from the 30-minute radio interview in which two male TV anchors in their early 60s talk to each other. The secondary source of the data is collected by having the primary data replicated by the two male announcers in their early 20's broadcasting in the university ra야o station of KAIST. With reference to the data collected in French and Korean, this paper provides the statistical frequency of each type of syllable structure in each language through the acoustic analysis of the spectrograms and renders a phonetic account of the characteristics of each syllable type in the two languages. Also discussed in this paper is the distributional condition in which each syllable structure is laid out in the speech context.

Wernicke's encephalopathy (WE) is an acute neurological disorder resulting from thiamine deficiency. Early diagnosis and treatment of WE is important to avoid persistent brain damage. Although histopathologic examination usually demonstrates pin-point hemorrhages in affected brain parenchyma, secondary hemorrhage is a rare but serious complication of WE. We experienced a rare case of intracranial hemorrhage related to WE in a 56-year-old male patient with malnourishment.

This research was administered in order to know the effects of heels on the foot by comparing the foot environmental characteristics when common shoes and elevated shoes are worn. First, 157 male adults in their 20s through 40s living in Busan were the inquiry subjects to reveal the shoes-wearing reality of adult males. Second, 7 male adults in their early 20s became the subjects for the experiments of wearing common shoes and elevated shoes. 1. Inquiry Results of Shoes-Wearing Reality Common-shoes wearers were in the order: 20s (43.9%) > 30s (24.8%) > 40s (8.3%). Elevated-shoes wearers were mostly 20s (12.1%), followed by 30s (8.3%) and 40s (2.5%). Among the wearing effects of elevated shoes were 'looking taller' (66.7%), 'no height complex & more confidence' (30.6%), and 'higher work efficiency' (2.8%). In sum, 97.3% of the male subjects believed in great positive effects by wearing elevated shoes. 2. Shoes-Wearing Experiment Results In foot skin temperature, significant differences between the two groups were admitted in outer foot a (p<0.05) and other areas (p<0.001), except in the instep. Elevated-shoes group had bigger skin temperature, while the order of temperature was the instep, the big toe, inner foot a/b/c and outer foot a/b/c. Significant difference was accepted in total sweat rate (p<0.05) and local sweat rate (p<0.01). Elevated-shoes group appeared higher in both rates. Significant difference (p<0.001) between the two groups was recognized in fatigue degrees after wearing, whereas significance (p<0.05) in elevated-shoes group was approved in fatigue before and after exercise. So elevated-shoes group experienced more fatigue, especially after exercise.

We previously used Southern blot analysis to detect restriction-length polymorphisms between male fertile and cytoplasmic male sterile (CMS) cytoplasms at the coxII and atp6 loci of the mtDNA of Capsicum annuum L. Two copies of atp6 were found in each male fertile and CMS pepper lines. Interestingly, one of the copies of atp6 in CMS pepper was a 3'-truncated pseudogene. The open reading frame of the coxII gene was the same in the fertile (N-) and CMS (S-) lines. However, the nucleotide sequence in the S-cytoplasm diverged from that in the N-cytoplasm 41 bp downstream of the stop codon. To develop CMS-specific sequence-characterized amplified region (SCAR) markers, inverse PCR was performed to characterize the nucleotide sequences of the 5' and 3' flanking regions of mitochondrial atp6 and coxII from the cytoplasms of male fertile (N-) and CMS (S-) pepper plants. Based on these data, two CMS-specific SCAR markers, 607 and 708 bp long, were developed to distinguish N-cytoplasm from S-cytoplasm by PCR. The CMS-specific PCR bands were verified for 20 cultivars containing either N- or S-cytoplasm. PCR amplification of CMS-specific mitochondrial nucleotide sequences will allow quick and reliable identification of the cytoplasmic types of individual plants at the seedling stage, and assessment of the purity of $F_1$ seed lots. The strategy used in this report for identifying CMS-specific markers could be adopted for many other crops where CMS is used for F1 seed production.

Anthropogenic disturbances, including coastal habitat modification and climate change are threatening the stability of kelp beds, one of the most diverse and productive marine ecosystems. To test the effect of temperature and irradiance on the microscopic gametophyte and juvenile sporophyte stages of the rare kelp, Saccharina angustissima, from Casco Bay, Maine, USA, we carried out two sets of experiments using a temperature gradient table. The first set of experiments combined temperatures between $7-18^{\circ}C$ with irradiance at 20, 40, and $80{\mu}mol\;photons\;m^{-2}\;s^{-1}$. The second set combined temperatures of $3-13^{\circ}C$ with irradiance of 10, 100, and $200{\mu}mol\;photons\;m^{-2}\;s^{-1}$. Over two separate 4-week trials, in 2014 and again in 2015, we monitored gametogenesis, the early growth stages of the gametophytes, and early sporophyte development of this kelp. Gametophytes grew best at temperatures of $8-13^{\circ}C$ at the lowest irradiance of $10-{\mu}mol\;photons\;m^{-2}\;s^{-1}$. Light had a significant effect on both male and female gametophyte growth only at the higher temperatures. Temperatures of $8-15^{\circ}C$ and irradiance levels of $10-100{\mu}mol\;photons\;m^{-2}\;s^{-1}$ were conditions for the highest sporophyte growth. Sporophyte and male gametophyte growth was reduced at both temperature extremes-the hottest and coldest temperatures tested. S. angustissima is a unique kelp species known only from a very narrow geographic region along the coast of Maine, USA. The coupling of global warming with high light intensity effects might pose stress on the early life-history stages of this kelp, although, as an intertidal species, it could also be better adapted to temperature and light extremes than its subtidal counterpart, Saccharina latissima.

The purpose of this study was to investigate the historical changes, and analyze functions and characteristics of western men's underclothes in the second half of the 20C. This study will examine how the social backgrounds influenced on the changes of the functions of men's underclothes and how the changes of outer garments were reflected on underclothes in the second half of the 20C. In the early, the second half of the 20C, underwears of functions was continued to cleanliness and comforts. In the later of the 20C, underwears came to be seen as expressing male sexual power when it became body-conscious. By the changes of outer garments. underclothes changed the same size of proportion. In the late 1960's, the turtleneck type of shirts were copied by outer garments, and we understand that underwear can influence on outer garments. The ruffles of the 18th century reappeared in the 1960's. This reactionism of the late 20C tells us about the relation between social environments and underwear. So the social backgrounds influenced on the formativeness of men's underclothes. We understand that underwear can influence on outer garments and outer garments can influence on underwear, too. The important characteristics of the second half of the 20C were the remarkable resemblance of some styles to those of the Past and the occasional blurring of the distinction between underwear and outerwear.

Fundamental frequency (Fo), jitter, shimmer, and harmonics-to-noise ratio (NHR) have been measured to see their interactions between the parameters using Multi-Dimensional Voice Program (MDVP). 100 Korean normal adults (50 males and 50 females) ranging from their early 20's to their early 30's produced the eight sustained vowels including /a/, /i/, /u/, /c/, /e/,/$\varepsilon$/, /i/, and /e/. The subjects were asked to read the above vowels five times in isolation with the interval of five seconds, respectively. Male voices, on the average, showed 130.7 Hz in Fo, 0.6696% in jitter, 1.8151% in shimmer, and 0.12 in NHR, while female voices showed 232.8 Hz in Fo, 0.9222% in jitter, 1.9199% in shimmer, and 0.1098 in NHR. As to the correlation coefficient, it was found that for male speakers jitter vs. shimmer, shimmer vs. NHR, Fo vs. shimmer, and Fo vs. NHR are statistically significant. It was found that for female subjects jitter vs. shimmer and Fo vs. shimmer are statistically significant. However, it is concluded that the correlation coefficient in females are not meaningful in a practical way though they are all statistically significant.
