Sialolithiasis consists of calcified structures in either the salivary gland or ductal system and alteration of salivary gland parenchyma. To investigate the clinicopathological features of sialolithiasis in Korean patients, we selected 60 patients with sialolithiasis diagnosed at the Seoul National University Dental Hospital. Their clinical records and radiographs were reviewed with the analysis of available histologic data from 32 cases. The male to female ratio was 1.1:1. Sialolithiasis is most common between the ages of 20 and 60 years and occurred most frequently in the submandibular gland (97%). Upon microscopic examination, most lesions showed moderate-to-severe inflammatory infiltration and parenchymal changes such as ductal metaplasia, acinar necrosis and fibrosis. Consequently, Korean patients exhibited clinicopathological features similar to those previously reported.

In this study, the representative hand shapes for the adult Koreans were analyzed by factor analysis and cluster analyses. The analyses were conducted on the anthropometric data of 58 hand dimensions from 325 subjects having nonhomogeneous demographics. Maximum hand circumference, first phalanx length of index finger, and ratio between the two measures were the independent variables for the cluster analyses. The results of the study showed that Korean hand shapes can be divided into 2 clusters irrespective of their size for each of the male and female group. There were slight differences in component ratio of hand shapes with respect to the occupation and the age, but their differences were not statistically significant. The representative Korean hand shapes and their anthrpometric dimensions could be used to design and establish proper sizing system for various hand operating devices.

An individual's food-related personal traits play an important role in influencing personal food choice and habits. According to culture, their influence can manifest differently. To ascertain personal traits about food, FNS (food neophobia scale) and FIS (food involvement scale) were employed in recent studies. This study aimed to understand the food culture and food choices of East-South Asians who live or stay in Korea through comparison of FNS and FIS. Eighty Koreans and 233 East-south Asians (Indonesians, Filipinos, Malaysians, Vietnamese, Thai, Singaporeans, and Bangladeshi) completed a questionnaire to measure FNS (10 questions), FIS (12 questions), and sociodemographic conditions (9 questions). ANOVA was conducted to ascertain FNS and FIS between the groups, and regression analysis was carried out to determine which sociodemographic factors had an effect. The items were analyzed to determine the differences according to gender, age, marital status, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. FNS showed significant differences between the groups with regard to sociodemographic characteristics, except gender, age, and marital status, whereas FIS showed significant differences in gender, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. The results of the regression analysis suggest that nationality strongly affected FNS and FIS, and FIS was also affected by gender.

Runt-related transcription factor (RUNX) 3 is well known as a developmental regulators, as well as candidate tumor suppressor gene in human breast cancer, gastric cancer, esophageal cancer, and so on. The present study was aimed to analyze the expression of RUNX3 protein in oral squamous cell carcinoma (OSCC) from Korean patients. The immunohistochemical stain was performed with 14 normal oral mucosa (NOM) and 25 OSCCs, and statistical analysis was carried out to find out the correlation between the expression of RUNX and clinicopathological parameters of OSCC patients. In OSCC, the expression of RUNX3 protein was found to increase more than in NOM. Moreover, in the univariate correlation analysis, the gender, regional lymph node metastasis, and histopathologic differentiation of OSCC patients were positively correlated with the expression of RUNX3 (p<0.05). These results indicate that RUNX3 can play a role as an oncogene in OSCC, in contrast to some reports on RUNX3 in other human cancers. In addition, RUNX3 may be considered as new malignant biomarker of OSCC.

A continuing challenge for English educators and policy makers in Korea is how to provide the right amount of good English education in an effective and efficient way, to help achieve the needed level of English communication skills. No efforts would turn out successful if the amount and the quality of public English education did not meet people's expectations. In order to plan and implement successful English education policies, it is necessary to figure out what kind of English education and how much of it are needed for Korean people. The current study aims to investigate what levels of English speaking proficiency Korean people perceive they need. The study first reviews some widely-used international English oral proficiency standards, then, compares those with the level descriptions of the Korea’s national curriculum of English. To gather information on the current level of English speaking proficiency, and the expected level of English speaking proficiency, 356 teachers (123 elementary school, 114 middle school, 119 high school), 696 students (179 elementary school, 222 middle school, 295 high school), and 650 parents (164 elementary, 212 middle school, 274 high school) from all the 16 district education authorities, were surveyed and interviewed. The results are presented with the discussion of the future directions of English education in Korea.

Oral squamous cell carcinoma (OSCC) is the most common cancer of oral cancers. Recent data suggest that chemokines could be essential players in carcinogenesis and that tumor cells express chemokine receptors and use chemokines to metastasize to the target organ in many malignancies in humans. The aim of this study was to test the hypothesis that expression of SNPs in chemokine, CXCL1 and CXCL2 correlates with oral squamous cell carcinomas in Korean population. The CXCL1 and CXCL2 genotypes were determined in 21 subjects with oral squamous cell carcinoma and 90 control subjects without oral squamous cell carcinoma. The genotypes were determined by direct sequencing. The genotype distribution and allele frequency within the OSCC patients were not significantly different from those of control subjects. But among OSCC subjects, there was significant difference of CXCL1 gene in the degree of nuclear aberration. These findings suggest that CXCL1 -442C/T polymorphism and CXCL2 -264T/C polymorphism are not related to the development of OSCC but polymorphism of CXCL1 gene might have a relation with progression of OSCC in Korean population.

It is presumable that properly designed earcons given simultaneously with visual information could enhance the situation awareness of operators when they are involving in highly complicate process control activities. In this study, population stereotypes of earcons with respect to process control information were identified using 60 Korean subjects. To do this, 11 most distinctive earcons were selected from various earcons having different pitch, rhythm, and timbre. Associations between the selected earcons and 40 pairs of adjectives used to describe the state of control in process were gathered from 37 subjects using a semantic differential method. Based on the results from multivariate analyses, the 40 pairs of adjectives were aggregated into three distinctive semantic dimensions. The emotional maps of the 11 earcons matched with the semantic dimensions were presented in this study. On the basis of these results, a general guideline was suggested for designing earcons to deliver process control information.

The incidence of multidrug-resistant strains of Staphylococcus aureus continues to increase in hospitals and the community all over the world. As the importance of miner surgery in dentistry gets greater recently, the frequency in use of antibiotics has been increasing. Although several cases of acquired infection in oral cavity in dental hospital has been reported, the research on isolation of S. aureus and evaluation of its antibiotic resistance from outpatients in the dental clinic has not been found yet. The aim of this study was to evaluate the antimicrobial resistance of S. aureus isolates. The isolation rate of S. aureus were 41.7% in dental hospital personnel, 60.4% in outpatients and 62% in dental hygiene students. S. aureus which showed resistance to penicillin were 88.6%, ampicillin 88.6%, erythromycin 8.6%, tetracycline 4.3%, oxacillin 4.3%, cefoteten 4.3%. Six strains of S. aureus showed the susceptible to all antibiotics tested. Sixty-four(91.4%) strains were multiple antibiotic resistance. Fifty-two strains(72.8%) resisted to AM-P. and Seven strains(10.0%) resisted to AM-P-E, AM-P-GM, AM-P-TE.

The fundamental purpose of this study is to investigate the degree of correlation between the receptive and speaking skills by comparing the scores of the TOEIC (the Test of English for International Communication) and the ESPT (the English Speaking Proficiency Test). A recent research (Cunningham: 2002) shows that gaining scores on the TOEIC do not affect much improvement of communication skills. In this study, two instruments were used to collect data: the TOEIC and the ESPT. These two tests were administered to freshmen at one of the universities at Kyungsang Province. On the basis of the TOEIC scores the participants got, they were divided into two groups: intermediate and basic. The results show that the overall correlation coefficient between the TOEIC scores and the ESPT test for all was 0.51. However, the correlation coefficient between these two test scores for the intermediate level was as low as 0.43 and the basic level 0.25. This study implies that interpreting the correlation between receptive and speaking skills should be cautious.

The mask-face interface design should consider the face shape to improve the half mask respirator's fit ratio. This study tried to design the mask-face interface using recent Korean face data. By using the data of 1536 men's 3D face scanning (Size Korea data), head clay mock-up was made and mask-face interface line was extracted from this head mock-up. Using this interface line, the half-mask prototype was made. According to the quantitative fitting test, the proposed mask was found to be well fitted (average fit-ratio > 100). The proposed method had two advantages. 1) The method could use massive head-related anthropometric data like Size Korea data. 2) The qualitative fit test (observation) could be conducted very quickly by fitting the prototype to the head mock-up. However, this method also had several limitations. 1) The head clay mock-up could be different according to the mock-up maker. 2) The average values of the head-related anthropometric data were used to make the head mock-up. Small and large size head mock-ups should be made and tested.

과거에는 단순한 생리처리 및 위생공간이었던 욕실에 대한 기능이 현대에 들어서는 생활의 활력을 충전하고, 자신만의 욕구와 실현의 공간으로써 활용되는 다기능 공간화 되어 가고 있다. 이러한 의식주에 대한 소비자들의 새로운 욕구와 변화가 나타나면서 현재 '욕실' 공간에서의 행위와 요구사항을 파악할 필요성이 높아져 가고 있다. 많은 수의 한국인들은 욕실사용에 있어서 서양의 입식(立式) 샤워 방식 외에도 욕조 밖이나 대야 등에 물을 받아 사용하는 등의 욕실사용 행태를 나타내고 있다. 따라서 이와 같은 한국인의 독특한 욕실사용행태를 설계에 반영함으로써 한국인의 욕실문화가 고려된 욕실구조 도출이 가능할 것이다. 본 연구는 욕실공간에 대한 사용 만족도를 높이기 위해 한국인의 욕실사용 정황과 사용 중에 느끼는 불편함과 종합적 감정 등을 조사하여 욕실 사용자의 요구사항을 도출하며, 욕실 공간계획에 있어서 건강, 위생문제를 해결하는 공간이자, 현대인의 신체특징과 라이프스타일이 반영 가능한 기본적인 설계지침 도출을 연구목표로 하고 있다.

Ramyen and Korean noodles (guksu) are popular foods in Korea and around the world. Since 1998, rice consumption in Korea has gradually decreased, whereas consumption of noodles has continuously increased. The purpose of this study is to assess the consumption of ramyen and Korean noodles of Koreans, using data from the Korean National Health and Nutrition Examination Survey (KNHANES) of 2007. Korean adults (>20) were selected to examine the associations between noodle consumption and food and nutrient intake and health status. SAS 9.1 and SUDAAN 9.1 were used for the data analysis. 10.3% of Korean adults consumed ramyen, and 15.4% consumed Korean noodles. The consumption of ramyen and Korean noodles were higher in men than in women, in lunch than in other meals, and in the lowest income quartile than the highest quartile. Ramyen and Korean noodle consumer groups consumed more grain products, seasonings, and oils than the nonconsumer group. The noodle group showed significantly lower systolic blood pressure than the non-consumer group. The noodle groups showed lower rates of hypertension and metabolic syndrome than the non-consumer group. From these results, we conclude that ramyen and Korean noodles may have positive health effects. More studies on the association between noodles and the health of Koreans and those in other countries should be done in the future.

The purpose of this study was to develop the pattern-making for Korean glove. To develop the pattern-making for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over th 15 years) were interviewed on the method of glove. The results of regression analysis(hand data) were as follows (unit: cm): wrist thumb tip length = middle finger length + 3.22, hand bread = 1.25 × middle finger length + 2.18, middle finger breadth at dist = 0.23 × index finger circumference + 0.4, maximum hand circumference = 3.15 × index finger circumference + 4.13, middle finger circumference = 0.91 × index finger circumference + 0.47, maximum hand thickness = 0.69 × index finger circumference －0.02. Hand measurements for glove pattern-making were developed: There were palmar hand length, hand circumference, index finger circumference and middle finger length.

There are differences of Cadmium (Cd) urinary concentration which is considered as indicator of renal tubular dysfunction in other countries, so we have reviewed domestic epidemiological data and suggested Korean health based guidance value (HBGV) for Cd to improve an efficiency of risk management. We decided to apply the WHO calculation model which considered the relationship between dietary intake and Cd concentration in urine sample. It is determined that Cd concentration 2.5 ug/g creatinine in urine as the prevalence of renal tubular dysfunction based on epidemiological data, because there is no renal tubular dysfunction and injury/lesion such as proteinuria at the concentration of 11.63 ug/g creatinine which is the highest Cd concentration in urine from the domestic epidemiological data. It is identified that the ratio between the Cd dietary consumption (8.3~10.4 ug/day) and Cd urinary concentration (0.38 ug/g creatinine) in Korean adult who predicting never been exposed to Cd are 21.8~27.3 and then it is applied to the corresponding model suggested by WHO. Also it is applied that 10% of bioavailability and 50% of excretion rate of absorbed to body (the ratio is 24) were assumed. The estimate of daily Cd consumption level which begins tubular dysfunction is 1 ug/kg bw/day, so we suggest the Korean provisional tolerable weekly intake (PTWI) as 7 ug/kg bw/week.

The information about time spent in microenvironments plays a critical role for an exposure assessment of the person concerned, considering the personal exposure relies on the characterization of activity patterns of the population at risk and human activities impact the timing, location, and level of personal pollutant exposure. The purposes of this paper were to present indoor time activity patterns of Korean from a population-based study and to determine individual factors of time spent in microenvironments. The population based study collected time activity pattern of about 32,000 Korean for two consecutive days. The mean times spent at home, other indoors, outdoors, and transportation in related to the whole sample of 19.025 people are 14.23hrs(59.3%), 6.80hrs(28.3%), 1.26hrs(5.2%), and 1.75hrs(7.3%) in weekday, respectively. Database provides information on how the proportion of persons in different locations changes by time of day in weekday. Here, we see that over 90% of respondents were in a residence from about 11 PM to 5 AM, and the largest proportions of respondents in offices, factories, schools and public buildings occur between 8 AM and 5 PM.

The purpose of this study was to develop the dimension of hand pattern-making for Korean glove. The glove pattern-making has difficult problem in combination of anthropometric and engineering aspects. In addition, existing dimension data are not enough for glove pattern-making. Therefore, to develop the dimension for glove this study comprehensive list of candidate hand data was reviewed and the manufacturers(career over the 15 years) were interviewed on the method of glove. The result of comparing between the structures in hand and existing glove pattern, there draw deduction from follows. Pattern-making for glove need size of hand length, thumb length, index finger length, middle finger length, ring finger length, hand circumference, thumb～ring finger circumference and maximum hand thickness.

The present study reports the findings of a study that analyzed the use of formulaic sequences in an NNS corpus (i.e., EFL teaching demonstration data) and an NS corpus (i.e., MICASE data). In order to investigate the structural and functional aspects of formulaic expressions in English, the most frequent 4-word formulaic expressions were identified and classified both structurally and functionally. The result of the analysis demonstrates Korean EFL learners’ overuse of the formulaic sequences. In other words, the repeated use of the formulaic sequences resulted in the high frequency of formulaic sequences in the learners’ data. The analysis of formulaic sequences by the structural subcategories shows the high frequency of the clausal expressions, which is one of the major characteristics of spoken discourse. The present study also reports the results of the functional analysis of the formulaic sequences, which indicate that both native speakers and learners mainly employed formulaic sequences to express epistemic and modality stance.
