This study aims to compare the awareness of the social value of public libraries between users and non-users to materialize the abstract concept of social value and, thereby, to present measures that can be applied to the library field. For this purpose, a survey was conducted in person or online for 15 days from May 7, 2023, targeting Paju citizens. Frequency analysis, factor analysis, independent samples t-test, and one-way analysis of variance were conducted on 206 valid response copies using SPSS 25.0. In the results, it is shown that, first, for awareness of the social value of public libraries according to socio-demographic characteristics, there were significant differences depending on age, with in particular, awareness among those in their 10s and 40s being higher than other age groups. For awareness of community development, the awareness of the female group was higher than that of the male group, while, for the awareness according to occupation, it is shown that awareness was highest in the following order: student, others, housewife, self-employed, and office worker. Second, for the awareness of the social value of public libraries, the awareness of the user group was higher than that of the non-user group in all areas. Third, for awareness of the social value of public libraries according to the level of library use, there was no significant difference between groups. In conclusion, it is suggested that measures to encourage non-users to become users, develop new content and services targeting male group and those in their 60s, and 20s, and strengthen community activities are needed to raise awareness of the social value of Paju City public libraries in the future.

In this study, 1,495 cases of computerized data collected as disease entities of oral and maxillofacial injuries among patient visiting S university hospital located in Seoul in 2009 were analyzed and following results were obtained. It was found that the injury incidence in male was greater than in female (1.49:1), it occurred most frequently in the age of 7~14 years old (19.6%), and its most frequent cause was falling down (25.9%). Injuries occurred in other place including beach and open-air (24.7%) most frequently, often developed in anterior teeth (43.2%) and posterior teeth (43.1%), their incidence was relatively higher between 15:00~17:00 (10.4%) and 19:00~23:00 (7.1%) O'clock. In the relationship between causes of the injury and the diagnosis based on the international classification of disease), falling, fall, impingement, violence, traffic accident, sports and own making accident caused most frequently lip and oral open injuries (S01.5), open fracture of tooth (S02.51), close fracture of tooth (S02.50), close fracture of mandible (S02.60), close fracture of tooth (S02.50), respectively. From the above results, it is necessary to understand general characteristics of oral and maxillofacial injuries and to consider their trends for the establishment of systematic complement policies and for the performing safety training and public relations activities.

Background: This study aimed to compare the subscapularis muscle volume between the intact groups (group I) and supraspinatus tendon tear groups (group T) based on the sex and three different age groups. Methods: Subjects with a group I and subjects with group T without any other lesions were retrospectively evaluated from among patients who received a magnetic resonance imaging (MRI) scan between January 2011 and December 2013. The MRI scans were studied by a consultant radiologist. The subscapularis muscle volume was compared according to the age and sex; the age groups were categorized as patients in their 40s, 50s, and 60s. The volume of subscapularis muscle was measured by three-dimensional reconstructed images acquired through the axial section of 1.5T MRI. Results: No statistically significant differences were observed between subscapularis muscle volume of the group I and group T, except for male patients in their 50s (group I: $100,650mm^3$ vs. group T: $106,488mm^3$) and 60s (group I: $76,347mm^3$ vs. group T: $99,549mm^3$) (p<0.05). Males had a larger mean volume of subscapularis muscle than females, and the subscapularis muscle volume decreased in a linear manner with increasing age. Conclusions: Decrease in subscapularis muscle volume was observed with increasing age, and the impact of supraspinatus tear on subscapularis muscle volume is age and sex dependent.

Magnetocardiography (MCG) is a non-contact, non-invasive, and harmless diagnostic tool to detect the abnormal electrical conductivities of the heart caused by the various coronary artery disease or cardiac muscular disease. The purpose of this study is to identify whether MCG signals and MCG parameter values vary depending on the location of sensor assembly. It will be an important reference for the standard measurement. Four healthy male subjects (33.3$\pm$6.3 years) participated in this study. Basal recording was made at 20 mm apart from the chest surface. All subjects were requested to take a regular breathe while MCG was taken. The gap between the chest surface and the bottom of the sensor assembly was 20, 40, 60, and 80 mm. Recording was made using 64 channel MCG system (Axial type, first order gradiometer) developed by Korea Research Institute of Standards and Science (KRISS). After resting for two minutes in a supine position on the bed in magnetically shielded room, MCG were recorded for 30 s. As the sensor location is getting away from the chest surface signal, the amplitude of R and T wave peak decreases to 70% (at 40 mm gap), 50% (at 60 mm), and 37% (at 80 mm) of the reference strength measured (y = $1.3903e^{-0.0169x}$, $R^2$ = 0.99; where y=amplitude remained after reduction, x=distance between chest surface and sensor location). The regression equations may be used as a good reference to calculate how much strength will be decreased by the distance. In MCG parameters, most values of parameters were decreased as the gap was increased. As an example, the current moment at T-wave peak reduced to 52% (at 40 mm gap), 33% (at 60 mm), and 19% (at 80 mm). However, the difference caused by the gap could be reduced by considering the distance when the MCG parameters were calculated. The study results can be used as a useful reference to design the baseline and the sensor location.

The purpose of this study was to evaluate the patterns of stresses arising from various life styles and their related sociodemographic factors in urban residents. The subjects were recruited from the population of two ‘Dong’s (administrative blocks) representative of Daejeon city through stratified cluster random sampling during the period ranging from June I st to Aug. 31 st, 2003. Self-administered questionnaires, including items asking about subjects' sociodemographic characteristics, daily life styles, measurement of stresses by General Health Questionnaire (Goldberg, 1978), were delivered to 396 residents and their responses were analyzed with the following results. 1. Based on the discriminant scores of HPI, 46.7％ of the subjects were found to have less than 4 points (poor life style), whereas 53.3％ had points higher than 5 (good life style). Higher than 5 points were scored more frequently in females than in the male, in the age group of 40's - 60's than the 30's, in the group with spouse than without, in the group with both spouse and offsprings than without, and in the group owning a house than not. 2. Based on the degree of stress, 17.7％ of the subjects were determined to be healthy, 74.5％ were potentially under stress, and 7.8％ were at higher risk of stress. The proportion of healthy individuals were significantly higher in the male, advanced aged group(40's and 60's), the group with higher education years( over highschool), with higher monthly income over two million Won, and with spouse, than their respective counterparts. On the other hand the proportion of the individuals potentially under stress and at higher risk of stress was significantly higher in the female, in the age group of 30's and over 60's, in the group with academic career lower than middle school, with monthly income lower than two million Won, and without spouse. 3. Based on the relation of HPI with degree of stresses, subjects with HPI scores lower than 4 had increased rate of falling into the groups under potential stress and at higher risk of stress, while on the other hand those with over 5 points were found to be healthy in light of stress. 4. Based on the specific relation of each item of HPI with degree of stress, the proportion of healthy individuals was higher in the groups who take appropriate hours of sleep(7-8hours), who take breakfasts everyday, who take physical exercises everyday, who don't smoke, who don't drink alcohol, who take snacks everyday, who are overweight and obese, whereas the proportion of the group under potential stress and at higher risk of stress was higher in their comparable counterparts. 5. The relation of mean scores of HPI with stress scores in both male and female subjects showed negative correlation that the higher HPI scores, the lower stress scores. 6. Multivariate regression analysis to reveal the factors influencing the stress of the subjects showed that for men the significant factors were age, education, presence of job or not, exercise, subjective health status, with the explanatory power of 26.3％. For women, they included educational years, presence of spouse or not, job, owning a house or not, sleeping hours, drinking habit, taking snacks, subjective health status, with the explanatory power of 31.8％. The above study results suggests that stresses of urban residents have significant correlation with daily life styles and this correlation is also remarkably distinguished by different age and sex.

Ten specimens (5 males and 5 females) of the pufferfish, fugu stictonotus ('gachilbog'), were collected at a fish market of Pusan, Korea in July 1993, and examined for anatomical distribution of toxicity by mouse assay method. The frequency of toxic specimens was $40\%\;for\;liver,\;60\%$ for ovary, $40\%\;for\;skin\;and\;60\%$ for bile in female puffers. The highest toxicities were 107, 107, 29 and 93MU/g for liver, ovary, skin and bile, respectively; and average toxicity $\pm S.E.\;values\;were\;14\pm11,\;48\pm22.4\pm3\;and\;12\pm9MU/g,$ respectively. The range of total toxicity was shown to be from 0 to 35,316MU. The characteristic pattern of toxin distribution observed on these specimens was exhibited; both muscle and testis were non-toxic, but others were weakly toxic. Also, there was significant difference for toxicity between male and female specimens.

This study was designed to be link in the chain of the investigation on daily life and consciousness of longevous people in Korea, and to investigated the dietary life and its habit of longevous people in the past. The dietary life ana its habit were surveyed on 379 subjects (male 121, female 258) of the aged who were above 80 years of age, from June to November in 1985. 1. Of the taste on staple food of longevous peoples in the past(between 40 and 60 years), 'meal mixed with barley' had the highest figure of 49.9%, followed by 'boiled rice'(47.0%). But it is showed that male preferred 'meal mixed with barley'(56.2%) to 'boiled rice'(41.3%). whereas female slightly preferred 'boiled rice'(49.6%) to 'meal mixed with barley'(46.9%). 2. Of the experience of the food taste of these aged in the past, 'not salted' and 'light' had the highest figures of all 40.6%. It is showed that longevous peoples preferred 'not salted'(40.6%) and 'light'(40.6%) to 'salty'(24.5%) and 'oily'(9.8% ), respectively. 3. By comparison of the intake state of animal protein(meat and fish) of these aged in the past, 'occasionally' was the highest of 55.4%, and decreased in the order of 'almost daily'(31.9%) and 'scarcely'(12.7%). Therefore, it is believed that 87.5% of longevous peoples has taken animal protein 'occasionally' and 'almost daily'. 4. The intakes of major foods above $4{\sim}6$ times a week of these aged in the past and present showed 50.4% and 67.5% for meat, fish, egg and soybean products, 26.6% and 51.5% for milk and its products, 89.9% and 81.0% for vegetables, 58.9% and 64.0% for oiled food, and 57.0% ana 62.934 for seaweeds, respectively.

This study is to get preliminary data for an effectiveness evaluation of abdominal examination and improvement of it. Abnormal cases of abdominal ultrasonography are classified by sex, frequency, diagnosis and age. 4,924 examinees were included at a university hospital of health promotion center from January to December in 1999. The results are as follows. 1. According to the distribution of sex, there are more male patients(55.0%) than females patients(48.0%). For men, 40's showed the highest percentage among examinees. For women, 50's were the highest. 2. The reason that they visited the health promotion center was that 'they wanted to check their health status'. This answers were reported the highest(59.3%). 3. Patients that had abnormal cases of abdominal ultrasonography were 48.3%. Liver, kidney, gallbladder showed the highest percentage of abnormal cases in order of organs. Additionally, abnormal cases were discovered in liver cases. 4. According to the frequency of abnormal cases among examinees, the slight fatty liver were the highest regardless of sex. Men had the slight fatty liver, kidney simple cyst, liver calcification and liver simple cyst in order of abnormal cases. Women showed the slight fatty liver kidney simple cyst, kidney calcification, liver simple cyst, and blood vessel tumor in order of abnormal cases. 5. For the abnormal cases of liver by sex and age, the 50's reported the highest number of abnormal cases in men(299 patients). In addition, 60's had the highest of disease rata 47.8%. For women, 50's reported the highest number of abnormal cases(361 patients). Over 70's patients had the highest of disease rata 52.6%. For kidney, men and women showed the highest number of abnormal cases -62 vs 44 respectively. Over 70's patients had the highest percentage of disease rata-23.2% vs 14.0% respectively. For gallbladder, the number of abnormal cases were the most in men's 60's (31 patients) and in women's in the same age group (32patients). Disease showed the highest percentage in men's 60's(7.6%) and in women's 70's (14.0%). 6. According to malignant tumor, 17patients were liver cancer, 2patients stomach ca and 1pt kidney cancer. 7. The relationship between the malignant tumor and the examination motive was that 'they wanted to check their health status(41.0%)' and 'regular checkup (24.0%)'.

This study was performed from March to June 1994 in ANsung Medical Center. We investigated serum components of 78 diabetics in the center, in addition to the nutrient intake status and anthrophometric status of 60 diabetics among them. We separated the latter into 2 groups(ⅰ) less tan 5 years of diabetic duration and ⅱ) more than 6 years of diabetic duration) and analyzed the clinical characteristics of each group. The results are as follows : \circled1 The average ages of male and female subjects were 57.1 and 58.9 years, respectively. The average diabetic duration of male subjects was 4.8 years and that of female subjects was 5.9 . The major occupational field of both male and female subjects was agriculture(33.3%, 36.1%). 50% of male and 75% of female subject's monthly incomes were less than 600, 000 won and 75% of male and 94.4% of female subjects had weekly food expense less than 40, 000 won. The nutrient intake status of the subjects was lower than RDA on the whole. There was no big differences between 2 the male groups of different diabetic duration , but calorie, protein , fat carbohydrate, phosphorus, iron and Vit B$_1$intakes of the above 6 year female group were appearently higher than those of the under 5 year female group (p<0.05). There were different intake tendencies between male and female subjects . For females. the longer the diabetic duration, the less intakes of calorie, protein , fat carbohydrate, phosphorus, iron Vit B$_1$, Vit B$_2$, and niacin were observed. Furthermore, the longer the diabetic duration in females , the more intakes of energy and nutrients, except Vit C were observed. Fasting blood glucose levels were 155mg/dl and 164mg/dl and Postprandial glucose levels were 242mg/dl and 247mg/dl for males and females respectively. Hb of both males and females , and Ht of males met the lower limit of normal status, The serum TG level was higher than normal , so that they seemed to suffer from hyperlipidemia ; their high HbAIC status indicated that the management of diabetes mellitus was poor. The total protein level of female subject was higher when compared with that of males(p<0.05). All subjects blood pressure were higher than normal , and the longer the diabetic duration, the higher was the blood pressure. The serum HDL-cholesterol levels of the above 6 year group male subjects were lower(p<0.05) than those of the under 5 year male group subjects, and the former group's systolic and diastolic blood pressures were higher than those of the latter(p<0.05). Levels of serum total protein, albumin and TG of the above 6 year female group were lower than those of the under 5 year female group(p<0.05). As the diabetic duration was extended, HDL-cholesterol and LDL-cholesterol levels showed a tendency to increase, while Hb, Ht, total protein, albumin, and A/G, which represent the nutrients state of iron and protein, were inclined to decrease. This result showed that serum lipid components went bad. To summarize the results, the longer the diabetic duration, the worse were the male subjects nutrient intake status, but those of the female subjects were good. With respect to serum components and serum lipid subjects Fe, protein, nutrition status and serum lipid component got worse as the diabetic duration was extended , implying the possibility of diabetes mellitus complication grows.

Purpose: This was a cross sectional descriptive study to introduce the Infants Coma Scale (ICS), describe mental status of high risk infants using ICS and explore the relationships between ICS and clinical variables in infants hospitalized in a neonatal intensive care unit of a university hospital in Korea. Methods: After ICS was developed and tested by the authors, a research nurse evaluated the mental status of the infants using the English version of ICS and obtained clinical information on the infants from their medical records. Results: Data from 88 infants were analyzed. About 60% were male, 90% were preterm births, and 40% had pathologic abnormalities. Their mean gestational age was 32.4 (${\pm}3.50$) weeks and the mean birth weight was 1,842 (${\pm}728.6$) grams. The Cronbach's alpha for the ICS was .78. There was a statistically significant positive correlation between ICS total score and five clinical variables including gestational age, birth weight, 1 and 5 min Apgar scores and respiration status. Conclusion: Mental status is an important parameter in nursing assessment. ICS is a valid and reliable instrument, which clinicians can easily use to evaluate the mental status of high risk infants.
