The purpose of the present study was to explore the radiological and acoustic characteristics of "Arae-a" (/${\cdot}$/) articulation in two male Jeju language speakers, focusing on selected measures in radiological images derived from computed tomography scans, as well as the first and the second formant measures in selected vowels. An elderly male speaker (a 78-year-old) and a young male speaker (a 34-year-old) participated in the study. During the production of four selected vowels, the shape of the vocal tract was identified, and selected measures were obtained from the elderly participant's computed tomography (CT) scans. For acoustic analysis, the participants were given a list of near-minimal pairs consisting of 112 words and asked to read them aloud. The results indicated that the "Arae-a" (/${\cdot}$/) articulation of the elderly speaker showed unique acoustic and radiological characteristics compared to other similar vowels, thus presenting substantial consistency with the descriptions of the "Hunminjeongeum Haeryebon." In contrast, the F1 and F2 measures of the young male's /${\cdot}$/ articulation were not distinguished from those of /ㅗ/. Current results, in part, support the scientific principles underlying the invention of "Arae-a," which reflects the shape of the vocal tract during production, and the necessity for further research.

Reproductive activity in the economically important insect, Antheraea mylitta is very important because the female reproduces only once in her life time and the aging is very rapid and costly. It is a capital breeder and strictly a monoandrous species. To know how strategically the insect behaves and the male allocates its ejaculate resource more prudently during its successive mating with virgin females to maximize its own fitness and the fitness of the female with whom it mated, both being most important to sericulture industry. So, the present study was undertaken and the results revealed fresh and virgin females always prefer to mate with fresh virgin males (84%) and receives high dose of ejaculates leading to higher hatchability than to virgin males of one day old (13.7%) and one day old males with mating experience (2.3%). The ejaculation size (as referred to eupyrene sperm count in the ejaculation) declined significantly over successive mating (r = -0.9931, P < 0.001), so also the male body weight (r = -0.9560, P < 0.001). The quantity of ejaculate passed to female also dramatically declined during aging (r = -0.9982, P < 0.001). It was found that male weight contribute substantially to the quantum of ejaculate (r = -0.9519, P < 0.001), so also higher fecund females receive relatively more ejaculate than the lower group to reach higher reproductive fitness. The life time fecundity was found to be $334{\pm}31$.

As recent developments of Immunology and Nuclear medicine, serum IgE and IgG values are helpful in the diagnosis and evaluation of the therapeutic effects of nasal allergies. But in Korea, air pollution and the increased use of food additives have become leading factors in nasal allergies, It seems to be induced by environmental change, especially industrialization and urbanization, so allergic rhinitis in our environment has changed in accordance with the changes made in the living environment. Therefore this study is attempted in order to observe a clinical analysis which places more importance on allergic rhinitis. We studied 200 patients who had visited Kyunghee Oriental Medical Center with allergic rhinitis from January 1, 1999 to December 31, 1999 The results were as follows: 1. The sex distribution was 114 males(57%) and 86 females(43%). In age distribution, the average age was 25. In males, ages ranged from 3 to 66 years old and the average was 23.81. In females, ages ranged from 4 to 67 years old and the average was 28.57. The peak age was 30～39 years old(24%); under 9 years old and 10～19 years old were each 18%; 20～29 years old was 22%; 40～49 years old was 11 %; over 50 years old 6.5%. The gulf between males and females showed a statistically significant difference(P<0.025). 2. In the age of onset, male' s maximum was 62.5, minimum was 0.25; female s maximum was 59.5, minimum was 0.2. Under 9 years old was the most with 34%(male 24%, female 10%), 10～19 years old was 18%, 20～29 years old was 22.5%, 30～39 years old was 13.50%, over 40 years old was 12%, The gulf between males and females were showed statistically significant difference.(p<0.014) 3. The average duration of the disease was 5.67 years. In male and female, the maximum was 30, the minimum was 0.05; under 5 years old was the most with 62%(male 34.50%, female 27.50%); 6～10 years old was 23%. So, under 10 years old was 85%. There was no statistically significant difference in the duration of disease. 4. Regarding type of residence, 47.50% of patients with allergic rhinitis lived in apartments, 52.50% lived in houses. In males, 29.50% lived in apartments, 27.50% lived in houses. In females, 18% lived in apartments, 25% lived in houses. There was no statistically significant difference in the residence by T-test and chi-test. 5. In the distribution of season, spring is the most with 29.5% of patients, winter 28%, fall 25.5%, and summer 17%. But there was no statistically significant difference. 6. After observing 200 patients with allergic rhinitis, classifying main symptoms into 5 types, sneezing was the main symptom in 177cases(88.50%), nasal obstruction in 176cases(88%), rhinorrhea in 169cases(84.5%), post nasal discharge in 87cases(43.50%), and itching in I04cases(52%). The Cumulus ration is 98.50% and symptoms overlapped with an average 3.57±0.1 times but in an analysis of variance of these symptoms, the gulf between males and females was not recognized as statistically significant by T-test and ANOVA. 7. Patients whose families have allergic diseases account for 90 cases(45%) : 49cases(24.50%) male and 41cases(20.50%) female. There were 4 cases (71.11 %) whose families have allergic rhinitis, 9cases(10%) of asthma, and 7.78% with allergic dermatitis. There were 61 (67.80%) cases of patients whose parents have allergic diseases; cases wherein the patient s child had allergic diseases numbered 13 (14.45%); and cases with a sibling with allergic diseases totalled 16cases (17.80%). There was no statistically significant difference in allergic disease regarding sex, parents, or siblings by chi-test. 8. Blood type: For males, type A is the most common, with 37cases(18.5%), followed by type B with 32cases(16%), type O 28cases(l4%) and type AB 13cases(6.5%). For females, type B is the most common, with 30cases(15%), followed by type O with 23cases(l1.5%), type A with 18cases(9%) and type AB with 13cases(6.5%). There was no statistically significant difference in blood type by chi-test. 9. In the selection of prefered food, most patients prefer cool food, with 98 such cases(49%), tepid food in 54cases(27%) and warm food in 48cases(24%). These showed a statistically significant difference in the selection of prefered food between males and females by chi-test(p<0.009). 10. The state of Past History was classified into II types. chronic hypertrophic rhinitis is the most common with 11cases (18.64%), tonsil and adenoid hypertrophy is 8cases(l3.56%), sinusitis is 6cases(10.17%), nasal septum deviation is 4cases, nasal polyp is 2cases, others are 10cases(l6.95%). No statistically significant difference in past history between males and females was shown, but a statistically significant difference was shown when males and females were compared with total cases by T-test(p<0.002, P<0.0008). 11. Regarding complications, 37 patients (28.91%) had sinusitis: 22cases(17.19%) in male, 15cases(11.72%) in female. Chronic hypertrophic rhinitis was found in 15cases(11.72%). Others are under 10%. There was no statistically significant difference in the type of complications between males and females, but a statistically significant difference was shown when males and females were compared with total cases by T-test(P<0.00l, P<0.007). 12. In the treatment, medication was used 1691 times, an average of 2.58 times. No.34 was used 370 times for 124 cases, an average of 2.98 times. No. 152 was used 318 times for 106 cases, an average of 3.00 times. No.151 was used 307 times for 97cases, an average of 3.16 times. No. 31 was used 117 times for 33 cases, an average of 3.55 times. No 25 was used 116 times for 33 cases, an average of 3.52 times. 13. In the duration of treatment, the most frequent is 1 week(69cases, 34.50%), the maximum is 20weeks, and the minimum is 1week. A treatment period of 2～3 weeks accounted for 32% of cases, a period of 4～5weeks accounted for 13.5%. The gulf between males and females showed a statistically significant difference in the duration of treatment.(p<0.01). There was a statistical significance when the males were compared with total cases by ANOVA(P<0.03). 14. A comparison between before-treatment and after-treatment showed a statistically significant difference in treatment by T-test (p<0.01) and F-test (p<0.0058).

This study was carried out to investigate the effect of nutritional knowledge on food habits of male employees in Korea. A questionnaire was developed and distributed to 265 male employees of Seoul and Kyunggi area in Korea. The data were analyzed by t-test and ANOVA using SPSS (ver 12.0). Regarding the general aspects of subjects, the highest percent of ages were between the age 21-30 year old. Most respondents were graduates from a university. About twenty percent of male employees' average income was 1-2 million won per month. Most of their families were nuclear families. Eighty three percent of the respondents did not experience any education on nutrition and obtained food and nutritional information from television and internet. The respondents had a high level of perceived knowledge (86.2%); yet, the accuracy of knowledge was lower than the perceived knowledge (72.31%). Regarding the nutritional knowledge, single groups showed a lower score than married groups and groups living with family. Higher nutritional knowledge correlated with higher educational levels, among man in their twenties and thirties. With regards to their eating habits, the frequency of food intake within a weekly period was significantly different; a large percentage of respondents had high frequencies of instant food, alcohol consumption, and smoking. The higher scores regarding dietary habits were for age groups ranging from 41-60 year old, married individuals, nuclear family groups and educational groups with university degrees. Based on the results of this study, male employees have problem concerning food habits in that they are unbalanced and have a tendency to skip meals. Therefore, for the improvement of nutritional status and eating behavior of male employees, the importance of nutrition needs to be emphasized with proper nutritional education programs.

Purpose: Malnutrition affects all age groups, but older adults are particularly more vulnerable to nutritional deficiencies. This study evaluated the age-specific factors affecting malnutrition in hospitalized older adults. Methods: A retrospective study was conducted on inpatient elderly people who received artificial nutrition from 2010 to 2017. Data of demographics, diagnosis, type of nutrition therapy, number of comorbidity, fall risk assessment, Acute Physiologic Assessment and Chronic Health Evaluation (APACHE) score, and intensive care unit admission were collected. Malnutrition was defined as a body mass index (BMI) of less than 18.5 kg/m². Patients were classified as the young-old (65~74 years old), the old-old (75~84 years old), or the oldest-old (85 years old or older). Results: A total of 7,130 older adults were included, and 4,028 patients were classified as the young-old, 2,506 into the old-old, and 596 into the oldest-old. Proportion of malnutrition was higher in the oldest-old compared to the other groups. In multivariate analysis, parenteral nutrition, alcohol, and high risk of falls were factors affecting malnutrition in all groups. Parenteral nutrition and alcohol in the young-old, high risk of falls in the old-old, and male sex in the oldest-old were the factors affecting malnutrition by the age group. Conclusion: Older age was the most significant factor affecting malnutrition. Specific strategies by age are needed to improve nutritional status in hospitalized older adults as influencing factors for malnutrition vary among different age groups.

Objectives: This study was designed to investigate the effect of Bombycis corpus on reproductive dysfunction caused by aging. Methods: The experimental group was divided into three groups: a control group consisting of 8-week-old male ICR mice without any treatment, An aging-elicited group (AE group) consisting of 50-week-old ICR male mice without any treatment, and a Bombycis corpus treatment group (BC group) consisting of 50-week-old ICR male mice with treatment Bombycis corpus extract (0.78 g/kg/day) for 6 months. After 6 months, histochemistry and immunohistochemistry of the testis were performed to investigate the effects of Bombycis corpus on the reproductive dysfunction caused by aging. Results: In the first step, Bombycis corpus increased spermatogenesis and distribution of sertoli cells in the seminiferous tubule, increased BrdU positive reaction in the spermatogonium at the basal part of the seminiferous tubule, and decreased the apoptosis of Sertoli cells in the seminiferous tubule. In addition, Bombycis corpus increased AR positive in Sertoli cells and $17{\beta}-HSD$ positive in leydig cells. Finally, Bombycis corpus decreased 8-OHdG positivite reaction in the spermatids of the seminiferous lumen, caspase-3 positivity in leydig cells, and HDAC1 positivite reaction in sertoli cells. Conclusions: These results suggest that Bombycis corpus increases spermatogenesis, decreases apoptosis of leydig cells and Sertoli cells, increases the production and action of testosterone in the testis, and inhibits DNA damages and DNA transcripts decrease in the testis, Thereby improving reproductive dysfunction caused by aging.
