포항분지 내의 천북층에서 산출되는 변질되지 않은 개형충 화석을 대상으로 중기 마이오세 동안에 한반도 남서부 부근에 영향을 주었던 고해양학적 조건을 이해하기 위 하여 동위원소 분석을 실시하였다. 서정리, 송학동 및 물천리 지역의 변질되지 않은 개형충의 산소동위원소 성분은 각각 -.2.2~ -0.7$\textperthousand$(PDB), -0.7~0.0$\textperthousand$ 과 -2.0~ -0.8$\textperthousand$이며, 이 성분에 의한 고해양해수의 온도는 각각 20~27$^{\circ}C$ (평균=24$^{\circ}C$), 17~2 $0^{\circ}C$ (평균=18$^{\circ}C$)과 20~26$^{\circ}C$ (평균=23$^{\circ}C$) 정도이다. 만일 중기 마이오세 동안에 포항 분지내 천해 해수의 산소동위원소 성분이 약 -0.34$\textperthousand$ (SMOW)이었다고 가정하면, 중기 마이오세 동안에 포항분지내 천해 해수의 고온도(paleotemperature)는 현재 포항부근 천해의 평균여름 온도와 거의 비슷하였거나 약간 높았던 것으로 추정된다. 분석된 개 형충 중 Cythere omotenipponica의 탄소동위원소 성분은 -0.8$\textperthousand$(PDB)로서 해수내의 탄 산염이온의 탄소동위원소 성분을 잘 반영하고 있으나, Aurial okumurai, Trachyleberis niitsmai, Urocythereis sp., Urocythereis cf. gorokuensis, and Acanthocythereis mutsuensis와 같은 나머지 개형충의 탄소동위원소 성분은 -5.2~ -3.4$\textperthousand$(PDB)로서 주위의 해수와 비평형상태를 이루고 있었던 것으로 나타난다. 이러한 결과는 고해양해수의 온도나 생산력의 차이에 의한 영향이라기 보다는 개형충 자체 내 의 생리적 영향에 기인한 것으로 여겨진다.

Pungsu theory is important one in the site selection and lay-out of traditional Korean village and house. In this aspect, Study with a view of Pungsu theory might be used as a proper method for understanding the traditional architecture in Korea. In this context, this study analyzes the Jeong, Dong-Ho's house which is designated no. 19 as an important folk cultural heritage, located in Jigok Ochu-gil 133-62, Godeok-myon, Yesan-gun, Chungnam province. The analysis of the site and space lay-out is carried out by Yong(Dragon), Hyoel(Auspicious Spot), Sa(Sands), Su(Water) aspects of the Pungsu(Fengshui) Hyungsei-ron. The house is depending upon soft dragon vein connecting with a earth type rear mountain. It looks southeast direction, Gonjwasonhyang(乾坐巽向). The hyeolseong(穴星) has classical venus shape, and there is no faults relatively. The Sasinsa condition is almost perfect that right blue dragon and left white tiger surround the hyeol with 3-4 layers and the facing mountain covers the front open area. The water flowing from inside of left and right mountain is joined in front of the house so it could stop flowing out of vital energy. Bibo forest(裨補樹) is placed properly to protect the easy disclose of water outlet. The house is well organized western house(西四宅) by analysis of Dongseosataek-ron(東西四宅論). Through the analysis, I found that the house has good Pungsu(Fengshui) environment fitted with Pungsu Hyungsei-ron. The house composed of small thatched roof is enclosed several times by low hills of back, left and right side. So it is believed that the site might be carefully evaluated by Yong, Hyoel, Sa, Su of Hyeongsei-ron for knowing whether the site condition could minimize the demage by strong winds and protect from the winter cold wind and secure water for drinking and farming and then selected. The method of Pungsu for evaluating the geographical condition of surrounding of a site is used as a traditional site analysis method for evaluating the suitability of long-term well and safe residence.

We prepared two samples of ultrafine ferrihydrite (FH) nanoparticle ensembles of quite a different origin. First is the biosynthesized sample (as a product of the vital activity of bacteria Klebsiella oxytoca (hereinafter marked as FH-bact) with a natural organic coating and negligible magnetic interparticle interactions. And the second one is the chemically synthesized ferrihydrite (hereinafter FH-chem) without any coating and high level of the interparticle interactions. The interparticle magnetic interactions have been tuned by modifying the nanoparticle surface in both samples. The coating of the FH-bact sample has been partially removed by annealing at 150℃ for 24 h (hereinafter FH-annealed). The FH-chem sample, vice versa, has been coated (1.0 g) with biocompatible polysaccharide (arabinogalactan) in an ultrasonic bath for 10 min (hereinafter FH-coated). The changes in the surface properties of nanoparticles have been controlled by XPS. According to the electron microscopy data, the modification of the nanoparticle surface does not drastically change the particle shape and size. A change in the average nanoparticle size in sample FH-annealed to 3.3 nm relative to the value in the other samples (2.6 nm) has only been observed. The estimated particle coating thickness is about 0.2-0.3 nm for samples FH-bact and FH-coated and 0.1 nm for sample FH-annealed. Mössbauer and magnetization measurements are definitely shown that the drastic change in the blocking temperature is caused by the interparticle interactions. The experimental temperature dependences of the hyperfine field hf>(T) for samples FH-bact and FH-coated have not revealed the effect of interparticle interactions. Otherwise, the interparticle interaction energy E_int estimated from the hf>(T) for samples FH-chem and FH-annealed has been found to be 121k_B and 259k_B, respectively.

The International Atomic Energy Agency's Statute in Article III.A.5 allows it“to establish and administer safeguards designed to ensure that special fissionable and other materials, services, equipment, facilities and information made available by the Agency or at its request or under its supervision or control are not used in such a way as to further any military purpose; and to apply safeguards, at the request of the parties, to any bilateral or multilateral arrangement, or at the request of a State, to any of that State's activities in the field of atomic energy”. Safeguards are essentially a technical means of verifying the fulfilment of political obligations undertaken by States and given a legal force in international agreements relating to the peaceful uses of nuclear energy. The main political objectives are: to assure the international community that States are complying with their non-proliferation and other peaceful undertakings; and to deter (a) the diversion of afeguarded nuclear materials to the production of nuclear explosives or for military purposes and (b) the misuse of safeguarded facilities with the aim of producing unsafeguarded nuclear material. It is clear that no international safeguards system can physically prevent diversion. The IAEA safeguards system is basically a verification measure designed to provide assurance in those cases in which diversion has not occurred. Verification is accomplished by two basic means: material accountancy and containment and surveillance measures. Nuclear material accountancy is the fundamental IAEA safeguards mechanism, while containment and surveillance serve as important complementary measures. Material accountancy refers to a collection of measurements and other determinations which enable the State and the Agency to maintain a current picture of the location and movement of nuclear material into and out of material balance areas, i. e. areas where all material entering or leaving is measurab e. A containment measure is one that is designed by taking advantage of structural characteristics, such as containers, tanks or pipes, etc. To establish the physical integrity of an area or item by preventing the undetected movement of nuclear material or equipment. Such measures involve the application of tamper-indicating or surveillance devices. Surveillance refers to both human and instrumental observation aimed at indicating the movement of nuclear material. The verification process consists of three over-lapping elements: (a) Provision by the State of information such as - design information describing nuclear installations; - accounting reports listing nuclear material inventories, receipts and shipments; - documents amplifying and clarifying reports, as applicable; - notification of international transfers of nuclear material. (b) Collection by the IAEA of information through inspection activities such as - verification of design information - examination of records and repo ts - measurement of nuclear material - examination of containment and surveillance measures - follow-up activities in case of unusual findings. (c) Evaluation of the information provided by the State and of that collected by inspectors to determine the completeness, accuracy and validity of the information provided by the State and to resolve any anomalies and discrepancies. To design an effective verification system, one must identify possible ways and means by which nuclear material could be diverted from peaceful uses, including means to conceal such diversions. These theoretical ways and means, which have become known as diversion strategies, are used as one of the basic inputs for the development of safeguards procedures, equipment and instrumentation. For analysis of implementation strategy purposes, it is assumed that non-compliance cannot be excluded a priori and that consequently there is a low but non-zero probability that a diversion could be attempted in all safeguards ituations. An important element of diversion strategies is the identification of various possible diversion paths; the amount, type and location of nuclear material involved, the physical route and conversion of the material that may take place, rate of removal and concealment methods, as appropriate. With regard to the physical route and conversion of nuclear material the following main categories may be considered: - unreported removal of nuclear material from an installation or during transit - unreported introduction of nuclear material into an installation - unreported transfer of nuclear material from one material balance area to another - unreported production of nuclear material, e. g. enrichment of uranium or production of plutonium - undeclared uses of the material within the installation. With respect to the amount of nuclear material that might be diverted in a given time (the diversion rate), the continuum between the following two limiting cases is cons dered: - one significant quantity or more in a short time, often known as abrupt diversion; and - one significant quantity or more per year, for example, by accumulation of smaller amounts each time to add up to a significant quantity over a period of one year, often called protracted diversion. Concealment methods may include: - restriction of access of inspectors - falsification of records, reports and other material balance areas - replacement of nuclear material, e. g. use of dummy objects - falsification of measurements or of their evaluation - interference with IAEA installed equipment.As a result of diversion and its concealment or other actions, anomalies will occur. All reasonable diversion routes, scenarios/strategies and concealment methods have to be taken into account in designing safeguards implementation strategies so as to provide sufficient opportunities for the IAEA to observe such anomalies. The safeguards approach for each facility will make a different use of these procedures, equipment and instrumentation according to the various diversion strategies which could be applicable to that facility and according to the detection and inspection goals which are applied. Postulated pathways sets of scenarios comprise those elements of diversion strategies which might be carried out at a facility or across a State's fuel cycle with declared or undeclared activities. All such factors, however, contain a degree of fuzziness that need a human judgment to make the ultimate conclusion that all material is being used for peaceful purposes. Safeguards has been traditionally based on verification of declared material and facilities using material accountancy as a fundamental measure. The strength of material accountancy is based on the fact that it allows to detect any diversion independent of the diversion route taken. Material accountancy detects a diversion after it actually happened and thus is powerless to physically prevent it and can only deter by the risk of early detection any contemplation by State authorities to carry out a diversion. Recently the IAEA has been faced with new challenges. To deal with these, various measures are being reconsidered to strengthen the safeguards system such as enhanced assessment of the completeness of the State's initial declaration of nuclear material and installations under its jurisdiction enhanced monitoring and analysis of open information and analysis of open information that may indicate inconsistencies with the State's safeguards obligations. Precise information vital for such enhanced assessments and analyses is normally not available or, if available, difficult and expensive collection of information would be necessary. Above all, realistic appraisal of truth needs sound human judgment.

Introduction: GTPases known as translation factor play a vital role as ribosomal subunit assembly chaperone. The bacterial Obg proteins ($Spo{\underline{0B}}$-associated ${\underline{G}}TP$-binding protein) belong to the subfamily of P-loop GTPase proteins and now it is considered as one of the new target for antibacterial drug. The majority of bacterial Obgs have been commonly found to be associated with ribosome, implying that these proteins may play a fundamental role in ribosome assembly or maturation. In addition, one of the experimental evidences suggested that Bacillus subtilis Obg (BsObg) protein binds to the L13 ribosomal protein (BsL13) which is known to be one of the early assembly proteins of the 50S ribosomal subunit in Escherichia coli. In order to investigate binding mode between the BsObg and the BsL13, protein-protein docking simulation was carried out after generating 3D structure of the BsL13 structure using homology modeling method. Materials and Methods: Homology model structure of BsL13 was generated using the EcL13 crystal structure as a template. Protein-protein docking of BsObg protein with ribosomal protein BsL13 was performed by DOT, a macro-molecular docking software, in order to predict a reasonable binding mode. The solvated energy minimization calculation of the docked conformation was carried out to refine the structure. Results and Discussion: The possible binding conformation of BsL13 along with activated Obg fold in BsObg was predicted by computational docking study. The final structure is obtained from the solvated energy minimization. From the analysis, three important H-bond interactions between the Obg fold and the L13 were detected: Obg:Tyr27-L13:Glu32, Obg:Asn76-L13:Glu139, and Obg:Ala136-L13:Glu142. The interaction between the BsObg and BsL13 structures were also analyzed by electrostatic potential calculations to examine the interface surfaces. From the results, the key residues for hydrogen bonding and hydrophobic interaction between the two proteins were predicted. Conclusion and Prospects: In this study, we have focused on the binding mode of the BsObg protein with the ribosomal BsL13 protein. The interaction between the activated Obg and target protein was investigated with protein-protein docking calculations. The binding pattern can be further used as a base for structure-based drug design to find a novel antibacterial drug.

The writer reports the conclusions gained from study about the cause of the hypersensitive large intestine syndrome with Dongeuibogam as the central figure through researching the disharmony among Body Essence, Vital Energy, Mentality, and Blood, mutual action of five viscera and six bowels, and external shapes. The hypersensitive large intestine syndrome is generally chronic and recurred in many cases, so it is more efficacious than symptomatic to treat according to find the contradictions of individual shapes. The shapes and cases suffering frequently the hypersensitive large intestine syndrome are Gi-kwa and Sin-kwa, having a long nose, having a bruised spot on Triple warmer, man with inclined mouth, Taeeum type, man with congested fluids, man with colic symptoms. The hypersensitive large intestine syndrome in Oriental medicine is recognized of diarrhea, constipation, abdominal pain, abdominal distention and fullness caused by seven emotions. In Dongeuibogam it can be found out the similarity in depressive symptoms due to disorder of Gi, stagnation of Gi, dysphasia due to disorder of Gi, diarrhea due to disorder of Gi, fullness of due to Gi, diarrhea due to phlegm-retention, retention of undigested food, immoderate drinking, hypo-function of the spleen, or deficiency, abdominal pain from colic symptom, and difficulty in defecation and urination, internal injury, diarrhea due to weakness and fatigue. If the Jung, Gi, Sin, and Hyul composed the human body is broken harmony, the function of large intestinal transmission would be fallen, so similar symptoms like the hypersensitive large intestine syndrome are gotten. Especially Gi-kwa suffers diarrhea, constipation abdominal pain, and abdominal distention and fullness due to depressive symptoms from disorder of Seven emotions or Seven Gi. And Sin-kwa suffers from the hypersensitive large intestine syndrome due to emotional restlessness having an influence on rhythmic movement of abdomen. Examining between five viscera and six bowels and the hypersensitive large intestine syndrome, Liver cannot disperse well having influence on mutual relation of Liver-Large intestine, Heart reduces the function of defecation and urination not to control the seven emotions, Lung having exterior and interior relation with intestine has an influence on primordial energy and let the main symptoms occur, Spleen circulating the body fluid let the main symptoms occur due to malfunction of circulation, Kidney locating in lower part of the body has deep connection with intestine, so let the disorder. Urinary bladder is connected with intestine in moisture metabolism, Stomach is connected in receive and transmission, Small intestine is connected in absorption and excretion, from small intestine pain disturbing the abdominal movement, Samcho managing the catharsis of lower heater if declined its function causes the hypersensitive large intestine syndrome. The colic symptoms of Front private parts which disorder in lower abdomen give rise to abdominal pains, difficulty in defecation and urination due to Cold are similar to the hypersensitive large intestine syndrome. The treatments of applying the shapes of colic syndrome advocated by Master Park can be efficacious cure in clinic. Researching after the clinical cases of Master Park advocating Hyungsang medicine, we came to know that plenty of prescriptions of internal injury are applied and take good effects.

진단은 도교 내단이론의 정립자이며, 북송 이래 사상계에서 가장 큰 영향력을 남긴 인물이다. 그는 다른 종교의 장점을 자신의 이론체계에 받아들이고 있음을 분명히 선언하고 있다. 그는 도교 수련과정의 논리적 부족함을 메우기 위해 유교의 역학(易學)을 도교 비전(秘傳)의 역학으로 대치하고, 육신과 정신의 이중구조를 통합하는 방법을 모색하는 과정에서 선불교의 마음수행법을 자신의 체계 속으로 끌어들였다. 진단의 내단이론은 정기신(精氣神)의 개념에 기반하여 '연정화기' '연기화신' '연신환허'의 단계로 수련하는 도식이다. 진단이 말하는 내단수련이란, '도교 방식으로 해석한 "주역"의 근본원리에 바탕을 두고서 마음을 고요하게 하는 선(禪)의 수행으로부터 시작하여, 그 고요함의 끝에서 온갖 변화에 신묘하게 통할 수 있고 지혜가 충만한 상태에 이르게 되면, 미묘한 정(精)의 흐름을 간취하여 이것을 기로 변화시키는 과정을 거쳐서 결국 복귀무극의 상태로 돌아가는 것'이라고 할 수 있다. 이러한 과정을 그는 "무극도"를 그려서 표현했다. 동양철학은 인간을 '현상적 존재'와 '본원적 존재'로 구분한다. 이러한 '존재 규정'으로부터 수도론의 논리가 성립된다. '자아' 또는 '자기'라는 개념을 어떻게 규정하느냐에 따라서 '현상적 존재'로부터 '본원적 존재'로의 회귀 내지는 도약 방법이 결정된다. 도교 내단이론의 정립자라 할 수 있는 진단은 이런 측면에서 독특한 내단수련론과 삼교회통론의 체계를 확립한 인물이다. 오늘날은 '자아상실의 시대' 또는 환경오염으로 인하여 생기는 '난치병의 시대'라고 할 수 있다. 자아의 회복과 건강한 삶을 위해서 몸과 마음을 연결짓는 진단의 수련론에 대한 검토와, 여기에 기초한 새로운 수련법의 모색은 여전히 의미 있는 일이다.
