한국의 미숙(未熟) 및 정상분만아의 식이별(食餌別) 장내균총에(腸內菌叢) 관한 연구 : I. 식이별 미숙분만아의 장내균총의 변화 I. Changes of intestinal microflora of Korean preterm infants on various milk feedings

박경식,강국희 한국낙농학회 1990 韓國酪農學會誌 Vol.12 No.4

본 연구는 우리나라 미숙 분만아의 생후 한달간 식이별 경시적 장내 균총의 변화와 분리 균속의 동정에 관한 연구로서 그 결과를 다음과 같이 요약할 수 있다. 1. 미숙 분만아의 모유 식이하의 장내 균총을 균속별로 보면 대체로 Bifidobacterium, Bacteroidaceae, Clostridium, Eubacterium, 그리고 Enterobacteriaceae의 순으로 나타났다. 2. 미숙분만아의 미숙아 분유 식이하의 장내균총을 균속별로 보면 Bifidobacterium, Enterobacteriaceae, Eubacterium, Bacteroidaceae 그리고 Clostridium의 순으로 나타났다. 3. 미숙 분만아의 미숙아 모유 및 미숙아 분유 혼합 식이하의 장내 균총을 균속별로 보면 대체로 Bifidobacterium, Bacteroidaceae, Streptococcus, Megasphaera 그리고 Clostridium의 순으로 나타났다. 4. 미숙 분만아의 정상아용 조제 분유 식이하의 장내 균총을 균속별로 보면 대체로 Bacteroidaceae, Bifidobacterium, Streptococcus, Eubacterium 그리고 Clostridium의 순으로 나타났다. 5. 미숙 분만아의 장내 균총에서 일반적으로 총 균수에서는 유익균이, 균속의 종류에서는 유해균이 우세하였다. 6. 34명의 국내 미숙 분만아의 분변 시료로부터 총 16속(Yeasts 제외)의 균을 분리하여 그 균속을 동정하였다. Due to the uniformity of the diet during early life, the composition of the intestinal microfloras is influenced dibectly by the kinds of nutrients during the first month after birth. Especially, in case of preterm infants, the first month after birth is the most important period for survival through their lifetime, and determination of intestinal microflora for this period is important to estimate their digestive diseases and metabolic disorders. This study made an attempt to classify the major intestinal microflora of Korean preterm infants on various milk feedings during the first month after birth. This results which were obtained are as follows: 1. Dominant genuses on total cell counts in gastrointestinal tracts, ranked from highest to lowest, from preterm infants fed preterm-formula-milk were Bifidobacterium, Bacteroidaceae, Clostridium, Eubacterium and Enterobacteriaceae. 2. Dominant genuses on total cell counts in gastrointestinal tracts, ranked from highest to lowest, from preterm infants fed preterm-formula-milk were Bifidobacterium, Enterobacteriaceae, Eubacterium, Bacteroidaceae and Clostridium. 3. Dominant genuses on total cell counts in gastrointestinal tracts, ranked from highest to lowest, from preterm infants fed mixture feeding(preterm-formula-milk and preterm-formula-milk) were Bifidobacterium, Bacteroidaceae, Streptococcus, Megasphaera and Clostridium. 4. Dominant genuses on total cell counts in gastrointestinal tracts, ranked from highest to lowest, from preterm infants fed term-formula-milk were Bacteroidaceae, Bifidobacterium, Streptococcus, Eubacterium, and Clostridium. 5. Dominant microflora on total cell counts in gastrointestinal tracts of preterm infants were lactic bacteria, and septic and pathogenic microflora were predominantly over kinds of species in the preterm infants guts. 6. Sixteen genuses(except on Yeast) were isolated and identified from fecal samples of 34 preterm infants in this experiment.

박경식,최세휴 한국구조물진단유지관리공학회 2009 한국구조물진단유지관리공학회 논문집 Vol.13 No.6

본 연구에서는 RC 중공슬래브 교량의 내하력을 향상시키기 위해 외부 프리스트레싱을 이용한 보강방법을 제시하였다. 효과적인 보강을 위해 Queen-post 형식과 King-post 형식이 고려되었으며, 축차무제약 최소화 기법(SUMT)를 이용하여 목표 내하율을 달성하기 위한 최적의 형상과 긴장력을 구하였다. 최적보강을 위한 목적함수는 재료비용을 무차원화한 비용함수로 구성하였으며, 제약조건은 시방서 규정과 내하율을 고려하여 형성하였다. RC 중공슬래브 교량의 보강을 실행한 후 그 결과를 분석하여 제안된 방법의 타당성을 제시하였다. In this study, the optimal method is applied to strengthening of RC hollow slab bridges using external prestressing. The Queen-post and King-post shapes are considered to find the effective tendon configurations. In order to achieve the objective rating factor, the optimal configurations and tendon forces are obtained by using the Sequential Unconstrained Minimization Technique (SUMT). The object function for optimal strengthening is constituted with the dimensionless function of material costs. The constraints are formulated by design specification and the rating factor. The validity of this study is presented by the analysis of the results of strengthening of the RC hollow slab bridges.

Substantial Study on Constituent Elements of the Foot Taeyang Meridian Muscle in the Human Truncus

박경식 대한한의학회 2009 대한한의학회지 Vol.30 No.3

Objective:This study was carried to identify the anatomical component of BMM (Foot Taeyang Meridian Muscle in the human truncus), and further to help the accurate application to real acupunctuation. Methods: The human truncus was stripped off in order to demonstrate muscles, nerves and other components, and to display the internal structure of the BMM, dividing into outer, middle, and inner parts. Results: The BMM in the human truncus is composed of muscles, nerves, ligaments etc. The internal composition of the BMM in the human truncus is as follows: 1. Muscle A.Outer layer: medial palpebral ligament, orbicularis oculi, frontalis, galea aponeurotica, occipitalis, trapezius, latissimus dorsi, thoracolumbar fascia, gluteus maximus. B.Middle layer: frontalis, semispinalis capitis, rhomboideus minor, serratus posterior superior, splenius cervicis, rhomboideus major, latissimus dorsi, serratus posterior inferior, levator ani. C.Inner layer: medial rectus, superior oblique, rectus capitis, spinalis, rotatores thoracis, longissimus, longissimus muscle tendon, longissimus muscle tendon, multifidus, rotatores lumbaris, lateral intertransversi, iliolumbaris, posterior sacroiliac ligament, iliocostalis, sacrotuberous ligament, sacrospinous ligament. 2.Nerve A.Outer layer: infratrochlear nerve, supraorbital n., supratrochlear n., temporal branch of facial n., auriculotemporal n., branch of greater occipital n., 3rd occipital n., dorsal ramus of 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, 10th, 11th, 12th thoracic n., dorsal ramus of 1st, 2nd, 3rd, 4th, 5th lumbar n., dorsal ramus of 1st, 2nd, 3rd, 4th, 5th sacral n. B.Middle layer: accessory nerve, anicoccygeal n. C.Inner layer: branch of ophthalmic nerve, trochlear n., greater occipital n., coccygeal n., Conclusions:This study shows that BMM is composed of the muscle and the related nerves and there are some differences from already established studies from the viewpoint of constituent elements of BMM at the truncus, and also in aspect of substantial assay method. In human anatomy, there are some conceptional differences between terms (that is, nerves which control muscles of BMM and those which pass near by BMM).

The Hebrew Proto-Masoretic Text of Habakkuk 3:1-4 and Its Interpretive Presentations in Other Biblical Texts

박경식 (재)대한성서공회 성경원문연구소 2016 성경원문연구 Vol.- No.39

The purpose of this study is to compare different texts’ nuance and variation based on redaction criticism and textual criticism in order to see how the texts were written, changed, and transmitted from one generation to the next. Frequently text critical scholarship presupposes that the old Greek of the Septuagint is actually the base text for the entire biblical tradition. However, there are some issues that do not support that hypothesis. I will compare five texts of Habakkuk 3:1-4 in the order of the suggested dates of the manuscripts: the Hebrew proto-Masoretic Murabba’at Scroll of the Twelve Prophets (Mur88; the second cent. C.E.); the Greek Septuagint (LXX) represented by Codex Vaticanus (Codex B; the fourth cent. C.E.), which is the oldest complete manuscript of the Greek Bible; the Syriac Peshitta (Peshitta; the seventh cent. C.E.) edited by Anthony Gelston; the Hebrew Masoretic text (MT; around 1,009 C.E.) based on Codex Leningrad B19A, which is the oldest complete Masoretic manuscript of the Hebrew Bible in the world; and the Aramaic Targum Jonathan on the Prophets (TJ; the sixteenth cent. C.E.) edited by Alexander Sperber. Through the analysis, the intention of the scribes who translated biblical texts is recognizable when we compare the texts because there are clear editorial works which reflect the scribes’ own theological and religious viewpoints. The proto-Masoretic text is the base text for other biblical texts because the LXX, the TJ, and the Peshitta clearly show that they are more interpretive presentations of the proto-Masoretic text. The scribes did not simply translate the text literally. They tried to correct any problem in the text using their own interpretation.
