본 연구의 목적은 교류분석 이론에 근거한 성인용 드라이버와 시간구조화 척도를 개발하고 타당성을 검증하는 것이다. 연구 대상은 성인 1,671명(남 594명, 여 1,067명)으로 1차(2018년)와 2차(2019년) 두 차례의 연구로 진행되었다. 1차 연구는 드라이버 척도 64문항(완벽하게 하라 12문항, 남을 기쁘게 하라 12문항, 서둘러라 12문항, 열심히 하라 14문항, 강해져라 14문항), 시간구조화 척도 71문항(폐쇄 14문항, 의식 14문항, 활동 10문항, 잡담 13문항, 게임 10문항, 친밀 10)에 대해 타당성을 검증하여 신뢰로운 문항을 선정하는 것이었다. 2차 연구는 1차 연구분석 결과 선정된 드라이버 척도 45문항(5요인 각 9문항), 시간구조화 척도 48문항(6요인 각 8문항)에 대한 타당성 검증과정을 거쳐 드라이버와 시간구조화 척도를 표준화하는 것이었다. 연구 결과를 보면, 개발된 드라이버 45문항과 시간구조화 48문항 모두 신뢰롭고 타당도가 높은 문항임이 확인되었다. 본 연구에서 개발된 두 척도는 급속한 성장을 이룬 한국사회 성인의 병리적 현상과 특성을 이해하는데 유용할 것으로 판단된다. 또한 드라이버와 시간구조화 척도는 심리특성 진단, 학교 교육, 기업 등 다양한 분야에서 진단도구로 활용될 수 있다는 점에서 그 의의가 있다고 할 수 있다. The purpose of this study is re-validate the validation of the Driver Scale and Time Structuring Scale devised by Moon, ho- young in 2017. This study is carried out two times with 1671 people - 1021 adults at first time and 650 at the other. The first study included 50 questions on driver scale devised by Moon, ho- young and 64 questions that added 14 questions: two questions on ‘Be perfect’, two on ‘Please others’, two on ‘Hurry up’, four on ‘Try hard’, four on ‘Be strong.’71 questions regarding on time structuring scale were studied in detail as the following: 11 questions were added to the 60 basic questions and the 11 questions were consisted of four questions on ‘Withdrawal’, four on ‘Rituals’, and three questions on ‘Pastimes’. The writers select highly valid and trustworthy questions using various method of analysis. The second study was conducted to validate the validation of the scale with 45 questions on drive scale and 48 questions on time structuring scale that were chosen from the first study result. Through these two studies researchers completed the Korean driver scale and time structuring scale. The result of this study clearly shows that 45 questions on driver scale questions and 48 questions on time structuring scale devised by Moon, ho- young(2017) including some modified questions and one newly invented question were highly valid and trustworthy in evaluating the validity of each scale. This result of this study proves that the driver scale and time structuring scale devised by Moon, ho-young(2017) is a valid tool for testing Korean adults.

<P>Natural phytochemicals of plant origin, including flavonoids, have been found to be potent antioxidants providing beneficial effects against oxidative stress-related diseases. The present study was carried out to investigate the antioxidant properties of morin, a flavonoid originally isolated from the flowering plants of the Moraceae family. Superoxide dismutase (SOD)-like activity and 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS(center dot+)) radical scavenging activity were determined. We also investigated the cytoprotective effects of morin against hydrogen peroxide (H2O2)-induced DNA damage and apoptosis in V79-4 Chinese hamster lung fibroblasts. Our results demonstrated that morin had strong scavenging effects against ABTS' radicals with enhanced SOD activity, which varied in a dose-dependent manner. Morin was found to reduce H2O2-induced intracellular reactive oxygen species generation and nuclear DNA damage, and it recovered cell viability damaged by H2O2 via inhibition of mitochondrial dysfunction-mediated apoptosis. Notably, the treatment of V79-4 cells with morin markedly enhanced the expression of heme oxygenase-1 (HO-1) but not quinone oxidoreductase-1, which was associated with the increased expression and phosphorylation of nuclear factor-erythroid 2-related factor 2 (Nrf2) and the downregulation of Kelch-like ECH-associated protein 1 expression. Based on our findings, we conclude that morin effectively ameliorated oxidative stress-induced DNA damage through intrinsic free radical scavenging activity and activation of the Nrf2/HO-1 pathway.</P>

Bucillamine prevents cisplatin-induced ototoxicity through induction of glutathione and antioxidant genes

Kim, Se-Jin,Ho Hur, Joon,Park, Channy,Kim, Hyung-Jin,Oh, Gi-Su,Lee, Joon No,Yoo, Su-Jin,Choe, Seong-Kyu,So, Hong-Seob,Lim, David J,Moon, Sung K,Park, Raekil Nature Publishing Group 2015 Experimental and molecular medicine Vol.47 No.2

<P>Bucillamine is used for the treatment of rheumatoid arthritis. This study investigated the protective effects of bucillamine against cisplatin-induced damage in auditory cells, the organ of Corti from postnatal rats (P2) and adult Balb/C mice. Cisplatin increases the catalytic activity of caspase-3 and caspase-8 proteases and the production of free radicals, which were significantly suppressed by pretreatment with bucillamine. Bucillamine induces the intranuclear translocation of Nrf2 and thereby increases the expression of γ-glutamylcysteine synthetase (γ-GCS) and glutathione synthetase (GSS), which further induces intracellular antioxidant glutathione (GSH), heme oxygenase 1 (HO-1) and superoxide dismutase 2 (SOD2). However, knockdown studies of HO-1 and SOD2 suggest that the protective effect of bucillamine against cisplatin is independent of the enzymatic activity of HO-1 and SOD. Furthermore, pretreatment with bucillamine protects sensory hair cells on organ of Corti explants from cisplatin-induced cytotoxicity concomitantly with inhibition of caspase-3 activation. The auditory-brainstem-evoked response of cisplatin-injected mice shows marked increases in hearing threshold shifts, which was markedly suppressed by pretreatment with bucillamine <I>in vivo</I>. Taken together, bucillamine protects sensory hair cells from cisplatin through a scavenging effect on itself, as well as the induction of intracellular GSH.</P>

Moon-Jin Jeon,Young-Ho Cho,김은혁,Dong-Gyu Kim,Young-Joo Song,홍승범,Jonghee Bae,Jun Bang,Jo Ryeong Yim,Dae-Kwan Kim 한국우주과학회 2024 Journal of Astronomy and Space Sciences Vol.41 No.1

Korea Pathfinder Lunar Orbiter (KPLO) is South Korea’s first space exploration mission, developed by the Korea Aerospace Research Institute. It aims to develop technologies for lunar exploration, explore lunar science, and test new technologies. KPLO was launched on August 5, 2022, by a Falcon-9 launch vehicle from cape canaveral space force station (CCSFS) in the United States and placed on a ballistic lunar transfer (BLT) trajectory. A total of four trajectory correction maneuvers were performed during the approximately 4.5-month trans-lunar cruise phase to reach the Moon. Starting with the first lunar orbit insertion (LOI) maneuver on December 16, the spacecraft performed a total of three maneuvers before arriving at the lunar mission orbit, at an altitude of 100 kilometers, on December 27, 2022. After entering lunar orbit, the commissioning phase validated the operation of the mission mode, in which the payload is oriented toward the center of the Moon. After completing about one month of commissioning, normal mission operations began, and each payload successfully performed its planned mission. All of the spacecraft operations that KPLO performs from launch to normal operations were designed through the system operations design process. This includes operations that are automatically initiated post-separation from the launch vehicle, as well as those in lunar transfer orbit and lunar mission orbit. Key operational procedures such as the spacecraft’s initial checkout, trajectory correction maneuvers, LOI, and commissioning were developed during the early operation preparation phase. These procedures were executed effectively during both the early and normal operation phases. The successful execution of these operations confirms the robust verification of the system operation.

Objectives : To analyze the characteristics of the pediatric patients who visited the emergency room and outpatient department of secondary hospital in order to properly guide pediatric patients to use emergency room and raise the efficiency Methods : The authors investigated and analyzed sex, age, visit day, visit time, length of stay, hospitalization and diagnostic entities of the pediatric patients who visited the emergency room and outpatient department of Wallace Memorial Baptist Hospital from January 2003 to December 2005 in a retroactive approach with their medical records. Results : For the three years, the number of total patients who visited the emergency room was 56,051 and among them, the number of pediatric patients was 7,490 (13.4%). The age group of 1 to 2 years was the largest with 2,488 (33.2%). The male to female ratio was 1.34:1. Sunday was the day of the week that the largest number of patienst visited with 2,375 (31.7%) and nearly half (48.4%) of the patients visited the emergency room during the weekend. The time when the most patient visited the emergency room was between 8 pm to 12 am. Regarding the length of stay, the highest number of patients (65.0%) stayed in the emergency room for on hour or less, and the average length of visit was 1.5 hours, which was rather short. Most patients (68.8%) left the hospital after taking simple physical examination and procedure(prescription). The most frequent diagnoses for the pediatric patients who visited the emergency room were acute pharyngitis (26.0%), acute gastroenteritis (20.7%), fever (6.6%). During the same period, the total number of pediatric patients who visited the outpatient department was 125,513. The age group of 3 to 5 was the largest with 36,041 (28.7%). The male to female ratio was 1.34:1. 6.0% of total outpatients required treatment in a hospital. Most frequent diagnoses of the outpatients were asthma (24.4%), pneumonia (12.0%), vaccination (8.7%), febrile convulsion (8.4%), acute pharyngitis (6.6%), acute gastroenteritis (5.8%). Conclusion : It is considered that a large number of pediatric patients still have used emergency room for treatment of simple and mild diseases instead of visiting outpatient department and/or primary hospital. Thus further efforts are required to properly guide pediatric patients to use emergency room and to raise the efficiency of their use.

J. H. Back, S. H. LEE, Y. J. Moon. The kinematical Evaluation of Natural Team's Butterfly Turn motion. Korean Journal of Sport Biomechanics, Vol. 14, No. 1, pp. 117-131, 2004. The foreign superior players and national team players' turning phase was measured, compared and analyzed to help the representative players improve the skill of turn. The underwater video camera used to analyze and evaluate the representative players' skill of turn in detail and the result is as follows. 1. The record for the phase of turn was similar to the rank of the last record. The improvement of the skill of turn was required because Korean players' record was lower than the foreign players' one. In case of 200m events the 1st turn was the fastest and it took more time as the turn is repeated. 2. It shows that the preparation phase and turning motion cause the difference between the players and within one player. 3. The horizontal movement of center of gravity moves to turning point slowly in the preparation phase, does not move nearly in the turning phase and increase again in the propulsion phase. Good record has short time for turn phase. The result means that the shorten the turning phase is the most important factor. Therefore the preparation for this is required. The vertical movement is maintained or increase a little and then move to from the turning phase. 4. The characteristic of horizontal velocity in center of gravity is that there is any big changes at the preparation phase, the faster velocity is found from the better record and the accelerating time is fast at the propulsion phasen. The wrong motion is made by not using the swimming velocity for turning and waiting and more time is required by this. 5. The angle of knee when the player touch the turning point is 106.22435.56 and the maximum angle of knee during the driving after the touch of tuning point is full extension. The size of maximum angle of knee did not match with the required time of propulsion phase. It seems that the individual difference is big when the players touch the turning point the angle of knee and the research for the individual angle which can reveal the maximum power should be carried out. The national team player's skill for the turn is behind the foreign players' one and a lot of problems were found. It shows that the players could not practice the skill for turn during the training. The 1st reason for it is the various facilities like underwater window or analyzing equipment like underwater camera with which the coaches can teach and correct the players' detailed skill. It is need to evaluate the players' detailed skill exactly and correct it by objective data to complete the good skill in the future. In this regard, the investment for the facility is necessary.

It is essential that we put the anticoagulant into the blood specimen of the CBC test. However, the value of some parameters in the CBC test can be changed whenever using some anticoagulants. EDTA anticoagulant is mostly used these days. There are 3 kinds of EDTA, that is K_(2-), K_(3-), and Na_(2-) EDTA. The author studies how many effects each the EDTA gets into the true value of blood specimen for MCV of RBCs. Especially we compared the MCV effect of different concentrations of 3 EDTA anticoagulants on the bias with time and instrument. Some results are gotten. In our results, K_(3-)EDTA anticoagulant shows more satisfactory MCV value than K_(2) or Na_(2-)EDTA. On using concentration of EDTA, 1.5㎎ EDTA/㎖ of blood show more satisfactory MCV value than 7.5㎎ EDTA/㎖ of blood. However, the choice of anticoagulant may be dependant on the different instruments.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
