In this paper, a Meridian balance measurement system is developed for Meridian characterization studies. The system utilized a method of Meridian electrical flow measurement. The system consists of 4-channel Meridian impedance measurement parts, filters, A/D converter, micro-controller, and personal computer. The system flows a low current between Meridian points and measures the energy amount by using the voltage drop on a standard register. The voltage drop is then A/D-converted and fed to personal computer for impedance calculation.

Twelve new Schiff bases were synthesized by condensation of two kinds of medicinal sulfonamides with eight kinds of aromatic aldehydes. They were identified by means of the elemental analysis, and UV and IR spectrochemical analyses. Antibacterial activity of the Schiff bases was tested in vitro against one gram-positive and seven gramnegative bacterial species. The results show that some of the compounds are more effcetive than each of corresponding sulfonamides against gram-positive St. aureus, exerting more remarkable activity compared to that against the gram-negative species. Therefore, the mechanism of action of the Schiff bases seems to be different from that of medicinal sulfonamides.

順菴 安鼎福의 豫防法意識 硏究

李光信,李應奎 단국대학교 1986 論文集 Vol.20 No.-

As it is well known the SILHAK(實學) was new academic wave of the latter period of the Chosun Dynasty. Soonam studied under the scholarship of SUNGHO(星湖:Yi ICH 李瀷 1681~1763,A.D.) who was the root(origin)of 'GENKi school'(近幾學派) within the 'KYONGSEeSHiYONG' school'(經世致用學派)^1) & 'YiYONGHOOSEANG' school'(利用淳生學派)^2) He was of the great conservative right wingers(守舊右派→左派:權哲身) and he was an extensive reader whose reading ranged over all the available books of his times. According to the catalog of his books: "SOONAM CHUNSEO HAEJE"(順 全書 解題: THE SOONAM BIBLIOGRAPHY DAEDONG CULTURALI(NSTITUTE, 1970, YUKANG PUBUSHING C0.,1984), he al1mored over 48 kinds in Books. That was the kind of scholar he was. From the depth and broad vision of his scholarship came the great achievement in philosophy of law. He cherished more than anything else 'HOKYUN'(好均:Equality by sharing) and 'KYESUN'(繼善:continuous in goodness)in 'SANGSUNYAKSOO'(上善若水: The best of goodness〈in the world〉is like water). The essentials of law(要法) of local autonomy deals with six areas. They are; ① Public welfare, ② Educational Code, ③ Legal Service, ④ Crime Prevention, ⑤ National Defense, ⑥ Kingship, etc. Somam authored a book named 'IMKWANJUNGYO' (臨官政要:Commissioned officers essentials in administration) The book was inspired by 'BOKAP LAW'(保甲法: Y00 10NG J00 劉宗周) and his insight of the latter period of the Chosun dynasty. TO the judicial and administrative officers (居官;KU KWAN) of those times, the book was an important guideline of administration. In the book he said, first(I) officers should work with wisdom, temperance and humility for ① Diligence in crime provention ② Prudence in punishment ③ Legal service, meaning eradicate all the hassels of legal action. secondly(Ⅱ). Superior officers' attitudes in leadership should be ① Think of the public before expressing the emotion(公意識:Public Consciousness) ② Work for public interest and Purification of society(淸濂) ③ Study all the law and its principles and practice with justice(明) ④ Face the pecoeple and subordinates with dignity and courtesy(威). In his other works, Soonam expanded 'HYANG YAK'(鄕約:village Discipline), to 'HYANG SA BUP'(鄕社法:community law) First(I). The political articles of 'HYAKGSA BUP are; ① Mutual watch of fire(火燭相戒) ② Mutual sharing of accidents(憂愚相恤) ③ Mutual sharing of congratulation(喜慶相賀) ④ Mutual watch against crime(盜賊相禦) ⑤ Mutual fear of law·(法令相畏) ⑥ Mutual prudence in Tax collecting and Payment(租賦相護) Secondly(Ⅱ). The Educational codes of 'HYANGSA BUP' are; ① Being dutiful to one's parents(孝順父母) ② Being respeclful to the elders(尊敬長上) ③ Being instructive to one's youngsters(敎訓子弟), ④ Being harmonious in local village(和陸賦里) ⑤ Being stable into one's living(各安生理〈計)) ⑥ Being without any falsehood(母作非僞). The educational codes reminds us of the phrase 'KYONG NO HYO CHIN'(敬老孝親) of 1985. Of course the Soonam's thought in this matter is much more clear and deep. They both could be used as basis for practice in law and ethics. In practice of political articles and educational codes Soonam believed in natural effective application rather than unnatural artificial system. And his self-regulating method was highly successful in; ① Judicial administration(形政) ② General administration (行政) ③ Tax collecting administration(租政) ④ National defense administration(國防) etc. It is my earnest hope that the Soonam's Philos9phy of law and his thought in law would be applied as the "Guide1ine for moral nature"(心性指針) as well as the promotions and further research for his spirit of law in the recent history of Korean thought in law.

The solidifying effect of solidified digested sewage sludge by converter slag was investigated through microscopic analyses including XRD, SEM and EDS. The XRD analysis of the solidified sludge showed that the main solidification products was CSH; in addition, Ca(OH)₂CAH and Ettringite were observed. The microstructure analysis by SEM showed that as the solidification proceeds, needlelike crystals and honeycomb appeared. The analysis of these crystals by EDS confirmed that the main components were Ca, Si etc. This also confirmed the general notion that the cement hydrate products had a solidifying effect.

The aims of this study is to survey the achievements of the in-service training which was executed by the In-Service Teacher Training Institute of Chungnam National University during the summer vacation in 1984. After analyzing the responses to the questionnaire which were collectted from 435 technical teachers attending the in-service training, we reached following conclusions as suggestions. 1) It is desirable to establish a committee to decide the levels and contents of the major subjects under the in-service teacher training institute. 2) Lessening the numbers of major subjects and extending the hours of each subjects will make effective results on in-service technical teacher training. 3) It will be better to give a chance to teachers to take option in the major study field. 4) The Ministry of Education should make a plan to give a course on computer programming to technical teachers regularly.

To evaluate the arsenic effect of fish endocrine disruption, crucian carp (Carassius auratus) were treated with 0.5 mg/L and 3.0mg/L of As₂O₃ for 14 days and gonadal development was examined by histological analysis. In ovaries from female crucian carps exposed to 3.0mg/L, immature follicles and atretic follicles were appeared while various normal developmental stages of oocytes were shown in control group. Body weight and Gonadosomatic Index (GSI) of treated carp were also decreased compared to control group. However, no other significant histological changes in liver or kidney were shown in this exposure scheme, This means that reproductive organs are more sensitive than other organs and arsenic may exert endocrine disrupting effect through inhibiting the development of reproductive organ in fish.

Study on Method of Sperm Aspiration and Injection into an Oocyte in Intracytoplasmic Sperm Injection(ICSI) Immobilization of spermatozoa prior to intracytoplasmic sperm iniection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first. Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization cleavage, percentage of grade I embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes ware inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30μl drop of mHTF supplemented with 10% heat-inactivated follicular fluid(FF) at 37℃. On day 2. embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF + 10% FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to earth treatment and ICSI was performed(88 head-first, tail-first). The rates of normal fertilization were 81.8% and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9% and 68.8%, 93.1% and 74.1% for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4%(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.

For a number of years it has been known that flexural vibrations in a plate can be damped by the application of a layer of viscoelastic material that is in turn constrained by a backing layer or foil. A common example is the damping tape currently used in aircraft. This paper presents a quantitative analysis of the damping effectiveness of such a constrained layer. As in the work of H. Oberst the damping is characterized by the loss factor η, which is the normalized imaginary part of the complex bending stiffness of the damped beam.
