Objective: Screening for colorectal cancer using guaiac-based fecal occult blood tests (gFOBT) is well established in Western populations, but is hampered by poor patient compliance due to the imposed dietary restrictions. Fecal immunochemical tests (FIT) do not require dietary restriction, but are more expensive than gFOBT and therefore restrict its use in developing countries in Asia. However, Asian diets being low in meat content may not require diet restriction for gFOBT to achieve equivalent results. The objective of this study was to evaluate and compare the validity and suitability of gFOBT and FIT or a combination of the two in screening for colorectal neoplasias without prior dietary restriction in an Asian population. Methods: Patients referred to the Endoscopic Unit for colonoscopy were recruited for the study. Stool samples were collected prior to bowel preparation, and tested for occult blood with both gFOBT and FIT. Dietary restriction was not imposed. To assess the validity of either tests or in combination to detect a neoplasm or cancer in the colon, their false positive rates, their sensitivity (true positive rate) and the specificity (true negative rate) were analyzed and compared. Results: One hundred and three patients were analysed. The sensitivity for picking up any neoplasia was 53% for FIT, 40% for gFOBT and 23.3% for the combination. The sensitivities for picking up only carcinoma were 77.8%, 66.7% and 55.5%, respectively. The specificity for excluding any neoplasia was 91.7% for FIT, 74% for gFOBT and 94.5% for a combination, whereas for excluding only carcinomas they were 84%, 73.4% and 93.6%. Of the 69 with normal colonoscopic findings, FOBT was positive in 4.3%, 23.2 %and 2.9% for FIT, gFOBT, or combination of tests respectively. Conclusion: FIT is the recommended method if we are to dispense with dietary restriction in our patients because of its relatively low-false positivity and better sensitivity and specificity rates.

Due to an increased demand for longevity risk analysis, various stochastic models have been suggested to evaluate uncertainly in estimated life expectancy and the associated value of future annuity payments. Recently updated data allow us to analyze mortality for a longer historical period and extended age ranges. This study followed up previous case studies using up-to-date empirical data on Korean mortality and the recently developed R package StMoMo for stochastic mortality models analysis. The suitability of stochastic mortality models, focusing on retirement ages, was investigated with goodness-of-fit, validity of models, and ability of generating reasonable sets of simulation paths of future mortality. Comparisons were made across various types of models. Based on the selected models, the variability of important estimated measures associated with pension, annuity, and reverse mortgage were quantified using simulations.

The purpose of this study was to investigate the wearing & fit of ready-made and online custom dress shirts by surveying middle-aged men aged 40-54 years in order to collect information necessary for making good fit dress shirts. Also, we analyzed whether there were significant differences in the actual wearing of dress shirts according to the stature of middle-aged men. The stature was classified according to KS K 0050 as $R(157{\leq}x<170)$ and $T(170{\leq}x<182)$. The 23 questionnaire items were divided into three categories: 'General purchasing behavior and wearing', 'Fit satisfaction of ready-made dress shirts' and 'Wearing and fit satisfaction of online custom dress shirts'. Through the results of the study, we could understand the actual wearing condition of ready-made and online custom dress shirts. Also, differences in stature groups were found. The significant differences according to the stature groups were found in the interest in fashion, the purchase criteria, the limitation of the shirt size selection due to stature and body shape, shirt size satisfaction, repair experience, dissatisfaction with purchase and the experience of purchasing online custom dress shirts. Suggestions should be made to improve dissatisfaction with stature groups in the ready-made dress shirts. In addition, the study confirmed the consumer demand for the online custom dress shirts. In order to activate the online custom market, the online custom dress shirts company needs to reduce consumer dissatisfaction and improve size suitability.

This study tried to suggest a drafting method to draft tight fit torso patterns suitable for adult males with a sway back somatotype and a bend forward somatotype by setting and distributing the ease through the completion of the somatic surface pattern using the 3D body surface segment method. It was intended to be presented as a drafting method. As for the research method, the suitability of the somatic surface patterns and the tight fit torso patterns were confirmed by the evaluation of virtual wear, and the patterns were modified and supplemented. The research results are as follows. In the first evaluation of the tight fit torso patterns, the average, for 55 evaluation items, was 3.92 points for the sway back somatotype and 3.89 points for the bend forward somatotype. In the second evaluation, the bend forward somatotype was 4.51 points and the sway back somatotype was 4.62 points. The chest circumference ease amount for the bend forward somatotype and the sway back somatotype are 6.5% (6.8 cm) and 7% (6.8 cm) of the chest circumference, respectively, and the distribution of the front and back ease is the same at 4:6 (2.72 cm:4.08 cm). The waist circumference ease amount is 6.5% (5.8cm) and 6.5% (5.6 cm) of the waist circumference dimensions, and the distribution of the front and backease are 5:5 (1.45 cm: 1.45 cm) and 4:6 (2.24 cm: 3.36 cm), respectively. The completed tight fit torso patterns were converted into institutional formulas and presented as a drafting method.

This thesis investigates influential attributes in clothing purchase through the examination of questionnaire concerning consumer satisfaction at the point of purchase, and clarifies the relationship between consumer satisfaction at the point of purchase and that in wearing. The results are as follows; 1. At interest stage, color, beauty, becomingness and suitability to occasion are influential (in this order): at trial stage, becomingess, color, others' reaction and fit: at adaption stage, color, becomingness, beauty, fit. 2. According to canonical analysis, consumer satisfaction at the point of purchase and that in wearing are closely related. (RCI = .97) It suggests that satisfaction in wearing depends largely on satisfaction at the point of purchase. 3. General satisfaction in wearing is closely related with such factors as predictive expecta-tion, satisfaction at the point of purchase, predictive disconfirmation, normative disconfirrna-tion, and product performance. According to repression results, those factors can explain $79\%$ of satisfaction ill wearing (R = .79). Above all, product performance and normative disconfirmation are highly influential.

The methodology of applying fabric stretch ratio in the grants pattern drafting was evaluated. The experimental fabrics employed in this study were 3 different knit fabrics with various stretch ratio in vertical or horizontal direction. The firm fitting pants pattern was modified by applying the fabric stretch ratio in vertical ana horizontal direction. The computer automatic drafting method was used for pants pattenl alteration. The suitability of the altered pattern was evaluated by the 7 clothing specialists, The results showed that fit of all experimental garments was improved in general. The garment which was constructed with the fabric having large difference between horizontal stretch ratio and vertical stretch ratio showed poor fit at crotch area. This result implies that computer aided pattern alteration is not appropriate when fabric stretch ratio is vary by the fabric directions.

With the purpose of developing a objective fitness evaluation system for knits, the basic bodice pattern for knit was drafted and the suitability of the altered pattern was evaluated. For each of nine different knits, six sleeveless shirts were made with patterns that were altered by different pattern alteration rate: 0%, 30%, 40%, 50%, 60%, or 70% of the stretch rate of the knit. The panel that was composed of 25 clothing specialists evaluated the fitness of the garments. The distance from the dress form landmark to the garment landmark was measured from each experimental garment. And the results of garment fitness evaluation and the measurement of distance from the dress form landmark to garment landmark were compared. The results of this study are as follows: There was high correlation(r$\geq$0.9) between the evaluation of the panel about the garment fit and the landmarks distance. The stretch rate of knits affected the evaluation of the garment fit. The stretch rate in course of knits affected on the garment fit at crosswise direction. The suitable pattern alteration rate was lower than 30% for the knits with high stretch rate in course. It was concluded that in order to get the appropriate knit bodice pattern length, the front bodice pattern must be less shorten than the back bodice pattern. The alteration rate at hip line must be lower than for waist or bust line.

This study was initiated to study suitability of the apparel sizing systems that utilized in women's ready-to-wear market. To achieve this, the researchers surveyed 383 women from the ages of 18 through 59. The result of this study are followed. 1) The targeted age of the apparel brand does not always correspond with the purchaser's age. The subjects tend to prefer the brands targeting younger women than their age. The women who prefer the brand targeting younger women than their age were less satisfied with the jacket size available in Korean apparel market. They also took into consideration their body size. 2) The subjects who prefer the brands aimed for younger women were dissatisfied with fit at waist and hips. 3) The result of this study also shows that the more sizes are needed for short and tall women. The subjects pointed out that hips of the pants gave worst fit. 4) KS standard size designation system which listed body measurements bust-hips stature was not well known to the consumers.

This study investigates the suitability of outdoor wear among female trekkers in their twenties or thirties and provides data for developing outdoor wear more suitable for young females. Recently climbing has gained popularity as a leisure activity to enjoy the beauty of nature that increases physical and mental stamina. A survey was conducted on 304 female consumers in their twenties and thirties who enjoyed climbing in order to investigate the suitability of outdoor wear among young female consumers. The questionnaire covered the subjects' demographic information, duration and goal of climbing, purchase and suitability of outdoor wear, and preferred design for outdoor wear. As for the yearly situations, when they utilized outdoor wear, the biggest number of respondents chose "autumn" as the season for climbing. Most of the respondents were non-professional trekkers who enjoyed climbing as a hobby or for health. As for the size, the upper garment was 90 and 85 in the order, and the lower garment was 70 and 67 in the order. The pants were the most common item they owned, followed by round T-shirts, windbreaker jackets, zipup T-shirts, and waterproof jackets. They mentioned moisture absorption and dry fabric breathability as the basic functions required of outdoor wear. The subjects displayed a preference for partial details under the design category. They most preferred the hood-type jacket with a detachable stand collar, the sleeve hem with a partial rubber band and velcro strap, a T-shirt with a stand color and zipper, the waist fit with proper room, pants with a partial rubber band waist, and straight silhouette pants.

Chemical water quality suitability for species (Ephemera strigata, Ephemera separigata, and Ephemera orientalis-sachalinensis group) of the mayfly genus Ephemera (Order Ephemeroptera) was analyzed with probability distribution models (Exponential, Normal, Lognormal, Logistic, Weibull, Gamma, Beta, Gumbel). Data was collected from 23,957 sampling units of 6,664 sites in Korea from 2010 to 2021. E. orientalis-sachalinensis occurred at the range of BOD₅ 0.3~11.1 mg/L (the best-fit Lognormal model); T-P 0.007~0.769 mg/L (the Gumbel model); TSS 0.4~142.2 mg/L (the Lognormal model). E. strigata occurred at the range of BOD₅ 0.4~7.4 mg/L (the Gumbel model); T-P 0.007~0.254 mg/L (the Lognormal model); TSS 0.4~17.1 mg/L (the Lognormal model). E. separigata occurred at the range of BOD₅ 0.4~2.6 mg/L (the R-Weibull model); T-P 0.007~0.134 mg/L (the Lognormal model); TSS 0.7~10.0 mg/L (the Lognormal model). Habitat suitability range of E. orientalis-sachalinensis was estimated to be 0.4~1.9 mg/L (BOD₅), 0.024~0.086 mg/L (T-P), 2.5~22.4 mg/L (TSS); that of E. strigata was 0.4~0.7 mg/L (BOD₅), 0.007~0.018 mg/L (T-P), 0.0~1.7 mg/L (TSS); that of E. separigata was 0.0~0.4 mg/L (BOD₅), 0.000~0.015 mg/L (T-P), 0.5~3.1 mg/L (TSS). In a relative comparision, E. orientalis-sachalinensis was estimated to be eurysaprobic, and narrowly adapted in high levels of T-P and TSS, E. strigata was estimated to be oligosaprobic and adapted in low levels of T-P and TSS, and E. separigata was estimated to be stenooligosaprobic and widely adapted in low level of T-P and TSS.
