Purpose The ASAN Medical Center, Nuclear Medicine performs TSH (Thyroid stimulating hormone) and FT4 (Free Thyroxine) tests 8 times per day. Accordingly, 70 ~ 80 kit tubes are consumed every day for the measurements and the time consumed for reagent dispensing averages over 170 seconds, where the TAT (turnaround time) may be effected when the number of test samples is larger than expected. Therefore, the following test was conducted with the purpose to reduce the number of kit tubes consumed, and reduce the time for reagent dispensing. Materials and Methods The test is based on applying the same reagent for tests where the number of samples is 30 or less. The test for TSH was conducted 9 times from July $1^{st}$ 2015 to July $10^{th}$ 2015. The test for FT4 was conducted 4 times from June $18^{th}$ 2015 to June $22^{nd}$, 2015. Standard Solution No.2 (0.153 uU/mL) and No.5 (4.96 uU/mL) was selected as the two-point standards for the TSH test, and Standard Solution No.3 (0.777 ng/dL) and No.4 (2.044 ng/dL) was selected as the two-point standards for the FT4 test. 38 test samples were subject to correlation analysis. Results For TSH, the result of the normal test shows ranges of 0.20 ~ 0.37 uU/mL for Control1, 0.53 ~ 0.71 uU/mL for Control2, and 6.77 ~ 7.94uU/mL for Control3, while the result of two-point calibration curve test shows ranges of 0.18 ~ 0.27 uU/mL for Control1, 0.53 ~ 0.71 uU/mL for Control2, and 7.30 ~ 8.52 uU/mL for Control3. For FT4, the result of the normal test shows ranges of 0.85 ~ 0.94 ng/dL for Control1 and 4.23 ~ 4.57 ng/dL for Control2, while the result of two-point calibration curve test shows ranges of 0.61 ~ 0.75 ng/dL for Control1 and 3.88 ~ 5.71 ng/dL for Control2. For TSH, the CV% of the normal test for Control1, Control2 and Control3 are 10.5, 3.3 and 3.6 respectively, while the CV% of the two-point calibration curve test for Control1 and Control1 are 12.4, 8.2 and 5.1 respectively. The result shows an outstanding correlation of TSH: y = 0.9985x - 0.0459 $R^2=0.9986$. For FT4, the CV% of the normal test for Control1 and Control2 are 0.70 and 0.71 respectively, while the CV% of the two-point calibration curve test for Control1 and Control1 are 8.7 and 16.2 respectively. The result shows an outstanding correlation of FT4: y = 1.2674x - 0.1133 $R^2=0.9824$. Conclusion The two-point calibration curve can be efficiently applied for TSH in cases where the number of test samples is not large, since the number of samples to be re-tested increases when the result is abnormal from the calibration curve. The two-point calibration curve test should not be applied for FT4 where the results do not consistently comply with the quality assessment range. Depending on how the two-point calibration curve is applied, up to 5 test tubes can be conserved per test, and the reduced time for reagent dispensing is anticipated to have a positive effect on the TAT (turnaround time).

본 연구는 국내에서 식재빈도가 높은 7개 조경수종을 대상으로 수관의 우수차집비율을 분석하고, 이를 기반으로 수종별 단목의 연간 우수차집량을 유추하는 계량모델을 마련하였다. 연구대상 수종은 느티나무, 단풍나무, 소나무, 왕벚나무, 은행나무, 잣나무, 전나무 등이었다. 수종별 수관의 평균 우수차집비율은 각각 잣나무 35.8%, 전나무 34.1%, 느티나무 31.0%, 소나무 27.6%, 은행나무 26.9%, 단풍나무 18.6%, 왕벚나무 18.4% 등의 순이었다. 계량모델의 r²은 0.90~0.99 범위로서 적합도가 높았다. 수종별 연간 우수차집량은 흉고직경 20cm 기준 느티나무가 5.1m³/주/년으로서 가장 많았고, 이어서 잣나무 4.1m³/주/년, 전나무 3.1m³/주/년, 은행나무 2.8m³/주/년, 소나무 2.1m³/주/년, 왕벚나무 1.9m³/주/년, 단풍나무 1.8m³/주/년 등의 순이었다. 수관폭 4m 기준의 경우에는 잣나무가 5.0m³/주/년으로서 가장 많았고, 이어서 전나무 4.4m³/주/년, 느티나무 4.1m³/주/년, 은행나무 3.3m³/주/년, 소나무 2.9m³/주/년, 단풍나무 2.1m³/주/년, 왕벚나무 1.9m³/주/년 등의 순으로 나타났다. 즉, 도시조경수의 연간 우수차집량은 상록수 또는 수관밀도가 높은 수종이 많은 경향이었다. 본 연구는 도시녹지의 우수차집 효과 관련 연구가 미진한 국내 현실에서, 조경수의 연간 우수차집량을 산정할 수 있는 초석을 새롭게 마련하였다. 이 연구결과는 정부, 지자체, 및 기업에서 시행하는 생태조경 사업과 관련하여 조경수의 우수차집 효과를 평가하는 공공기반기술로서 유용할 것으로 기대한다. This study developed quantitative models to estimate the rainfall interception by seven native landscape tree species based on throughfall measurements. The tree species considered in this study were Abies holophylla, Acer palmatum, Ginkgo biloba, Pinus densiflora, Pinus koraiensis, Prunus yedoensis, and Zelkova serrata, which are frequently planted in the Korea. Among these species, 35.8% of the annual precipitation was intercepted by P. koraiensis, 34.1% by A. holophylla, 31.0% by Z. serrata, 27.6% by P. densiflora, 26.9% by G. biloba, 18.6% by A. palmatum, and 18.4% by P. yedoensis. All the quantitative models showed high fitness with r² values of 0.90-0.99. The annual rainfall interception from a tree with DBH of 20 cm were greatest with Z. serrata (5.1 m³/yr), followed by P. koraiensis (4.1 m³/yr), A. holophylla (3.1 m³/yr), G. biloba (2.8 m³/yr), P. densiflora (2.1 m³/yr), P. yedoensis (1.9 m³/yr), and A. palmatum (1.8 m³/yr) in order. Thus, evergreen tree species or those with a relatively high crown density were more effective in intercepting rainfall. In particular, the annual rainfall interception by Z. serrata was the greatest because its crown area, volume, and density were higher than those of the other species. This study pioneers in quantifying annual rainfall interception for landscape tree species in Korea. The study results can be useful for evaluating rainfall interception by landscape trees in urban greenspace design for governments and corporations.

Purpose In this study, the monthly population distribution was calculated for statistical verification of 10 tests (CA19-9, CA15-3, testosterone, PTH, calcitonin, AFP, CEA, CA72-4, PSA, estradiol) with changed reagents, and the trend of change By comparing and analyzing the results, we want to verify the accuracy of the results and improve the reliability of the test. Materials and Methods From June 2021 to February 2023, for the 10 items in which the reagent was changed, the monthly percentage and standard deviation index before and after the reagent change were compared, respectively. At this time, the reference value was arbitrarily set for the comparison group in consideration of the reference value of the test item, and the groups were subdivided and compared, and the standard deviation index allowed range was -2.0 or more and 2.0 or less. Results For CA19-9, CA15-3, AFP, CEA, and calcitonin 5 test items, the change in monthly ratio in all test sections before and after the reagent change was kept constant. On the other hand, for CA72-4, PSA, testosterone, PTH, and estradiol items, the standard deviation index exceeded the acceptable standard after changing the reagent. CA72-4 test items showed an increasing trend in standard deviation index in the test section exceeding the reference value. In the case of the PSA test item, the maintenance ratio of 0.04 ng/mL was significantly decreased after changing the reagent. The testosterone test item had a standard deviation index of -2.5 in the test section exceeding 10.1 ng/mL after changing the reagent, and the standard deviation index of the PTH test item was out of the acceptable range in all test sections. It was confirmed that the estradiol test item showed an overall increase in the result value. Conclusion Through this study, the continuity and accuracy of the test results could be verified. It is considered that the stability of the test can be secured by analyzing the factors affecting the test result and solving the cause for the test item whose standard deviation index is out of the acceptable standard.

Objectives:The aim of this study was to investigate the factors that determine the intention to receive cosmetic plastic surgery, with particular attention to gender role identity and temperament character. Methods:A total of 226 university students completed the self-rating scale, including cosmetic surgery intention and experience. The Korean Sex Role Inventory(KSRI), Multidimensional Body Self Relation Questionnaires(MBSRQ), Brief Body Dysmorphic Questionnaire(BBDQ), and Temperament and Character Inventory(TCI) were also measured. To evaluate the difference of body image and cosmetic surgery intention, according to sex and gender role identity, chi-square test and one-way analysis of variance were performed. To find the influential TCI dimension for cosmetic surgery intention, multiple regression analysis was performed. The mediating effect of body image in a relationship between gender role identity score, temperament character and cosmetic surgery intention was also evaluated by multiple regression analysis. Results:Body satisfaction was different according to gender role identity. The androgyny types were more satisfied with their appearance than the undifferentiated types, in both sexes. Cosmetic surgery intention was significantly different according to sex only, but not gender role identity. High masculinity and femininity scores were significantly associated with body image satisfaction, but these were not associated with intention to receive cosmetic surgery. There was a full mediating effect of body image on the relationship between cosmetic surgery intention and increased harm avoidance(HA), decreased self-directedness(SD), and decreased cooperativeness(C). Conclusion:These results show that innate difference of sex might be more important to cosmetic surgery intention than acquired gender role identity. Moreover, individuals with high HA, low SD, and low C may have difficulty in forming positive body image due to vulnerable temperament and low self-acceptance character. Negative body image, along with these characteristics would likely lead to cosmetic surgery intention.
