Tuberculosis infection is a rare but important side effect of anti-tumor necrosis factor agents that are widely used in the treatment of rheumatoid arthritis. A 63-year-old woman with rheumatoid arthritis who had been treated with etanercept visited the hospital because of polyarthralgia and right neck pain. Before use of etanercept, she was treated for latent tuberculosis. When the patient came to the hospital, she had no respiratory symptoms. But, we found abnormal findings in regularly follow-up chest x-ray. She was diagnosed as reactivation of latent tuberculosis by bronchoscopy. After stopping the etanercept, she has been treated with anti-tuberculosis agents, disease modifying anti-rheumatic drugs, and intra-articular steroid injection. We report here on this unusual case along with a review of the relevant literature

A study on the nonlinear fracture mechanics was made on the low-cycle fatigue crack growth in SUS304 stainless steel under trapezoidal and sine stress wave at 650℃. The high temperature low cycle fatique crack growth behavior was classified into two categories: cycle-dependent and time dependent. The cycle-dependent crack growth rate correlated well with J integral range ?J, whereas the time dependent crack growth rate was characterized by modified J integral Jex. A parameter βwas found useful in predicting the transition from the cycle-dependent crack growth to the time-dependent crack growth. Conducting the experiment of high temperature fatigue crack propagation in trapezoidal, and sine stress wave, following conclusions were obtained. 1. Crack propagation behavior can be classified into cycle-dependent and time-dependent. 2. The transition of cycle-dependent crack propagation to time dependent one could be predicted bt either parameter βor ?J/ ?J?.

This study focuses on changes in the kinds of flowers, colors, shapes of bridal bouquet in Korea for 50 years from 1950's to 1990's. The results show that two to three kinds of flowers were used in 1960's and 1970's, but various materials were used in 1980's and 1990's. White chrysanthemums rank first in 1950's and 1960's, carnations in 1970's, but roses and cymbidiums in 1980's, and use of cymbidiums, roses, and denphalae increased in 1990's. When it comes to foliage, camellia leaf used most frequently until 1960's and Asparagus in 1970's, but use of various tropical foliage such as scindapsu, ivy, Rumora fern increased in 1980's. In colors, white was most preferred in 1950's and 1960'sl pink was added in 1970's, but both white and pink were used in bouquet and boutonniere in 1990's. In shape, large arm bouquet was most preferred in 1950's. Round bridal bouquet with long asparagus stem was most favorite style in 1960's and 1970's, cascade shape and empire bouquet in 1980's, and various bridal bouquet such as cascade, round, triangular and free style in 1990's. In boutonniere they used triangular most frequently.

A field study was conducted to investigate the removal efficiency and performance of contact oxidation treatment system installed and operated in two locations of stream flowing to the Masan Bay. The removal of organic matters from stream water flowing to the already eutrophicated bay is getting more important in order to restore the water quality. The removal efficiencies of BOD, SS and ABS loading rate were 52~63%, 50~70% and 60~85%, respectively, whereas 10~25% of total nitrogen and 25~40% of total phosphorus were only removed. The effluent water quality did not meet the goal class of water regulation standards. Inflow rates to contact oxidation treatment showed seasonal and hourly variations. The treatment capacity installed is now enough to handle the present inflows, thus it was suggested that this system should be operated to supply only the volume of oxygen to require the actual loading to the treatment system and the aeration system would be intermittently operated for the improvement of nitrogen and phosphorus removal. It was found that inflow rate should be controlled for detention time of contact oxidation to maintain at least more than 1.5 hr. When microbiological species of sludge and sludge accumulation in the lower steps of contact oxidation process was examined, proper draw-out of sludge from the system was also an important operating parameter.

Saturated marine clays are consolidated under applied loads caused by deposit-process or human interruptions. The consolidation process results in densification and in turn increment of the undrained strength of a clay deposit. In a clay deposit, the undrained strength is increasing with the effective overburden pressure, which also increases wit depth. The strength variations with effective overburden pressure(or depth) is characterized by so called "Cu/P" ratio. In korea, the empirical formula proposed by Skempton has been used to estimate the undrained strength profile of a clay deposit without any sometimes varification of the applicability to clay deposits in Korea. In the thesis, the test data for some clay deposits along south -west coast in Korea were analized to test the applicability of Skempton formula. A new formula pertinent to the deposits was developed. Also, Initial elastic and secant moduli were studied.

Recently, multilayer perceptron type neural networks are widely used for nonlinear system/signal modeling. However, although their successful implementation, it is difficult to get some information about system/signal from the neural network modus(e.g. stability, frequency analysis) because of the highly nonlinear structures of the neural networks. One solution is to approximate the neural networks to well known Volterra series. Since the Volterra series representation provides a general representation of nonlinear systems both on time/frequency domain, we can get frequency domain information for the systems/signals. In this paper, we present the Volterra series expansion of the 1¹/₂ type feedforward neural networks.

It is well-known that the Netherlands overcome the economic crisis through social concertation among employers, workers, and government. Employment growth based on work-sharing and wage moderation is named 'Dutch miracle'. Introducing the free competition model in labour market, Dutch polder model enforced the framework of solidarity and consensus enlarging social welfare benefits to the part-timers, foreigners and retirees. In this respects Dutch model differs fromthe Anglo-Saxon model based on competition and exclusion. This article reviews the characteristics of the Netherlands' corporate pension system and emphasize its significances in the lights of political economy. The primary reason we are focusing the Dutch corporate pension system is that it is very important institutional device keeping away from prevailing proprietary individualism and conflicts of interests between worker-as-wage earner and worker-as-shareholder and between younger and older generations. This paper proceeds in three steps. In the first step, the key points and new strains of dutch polder model based on socialconsensus, so called Wassenaar Accord etc., are sketched. Secondly, the main features of the current corporate pension plans in the Netherlands will be discussed. Finally, the implications to the new model building will be discussed in points of present economic reforms in Korea.

토마토 에 있어 RAPD 분석을 위한 PCR에 영항을 미치는 요인들을 결정하기 위한 일련의 실험이 실시되었던 바, 최종 50㎕의 반응용액내에 25ng의 template DNA, 5pM의 10-mer primer, 0.05mM의 dNTP와 0.25 unit의 Taq DNA polymerase의 조건이 본 실험에 사용된 토마토의 PCR에 최적으로 사료되었다. 본 실험에서는 Operon사의 A_(9)~A_(14) random primer들이 토마토에 있어 적합한 것으로 판단되었으며 45 cycle의 반응횟수가 명확한 다형화 band 형성에 필요한 충분량의 DNA를 확보하기에 적합한것으로 나타났고 38℃의 annealing 온도 가 공시된 토마토의 PCR에 적합한것임을 보였다. 반응 요인들의 농도와 양에서 나타난 결과로 보아 그들의 효과에 있어 각각은 매우 상호의존적인 관계에 있는것으로 판단되었다. A series of experiments were initiated to examine factors affecting Polymerase Chain Reaction(PCR) in studying Random Amplified Polymorphic DNA(RAPD) of tomato. The results showed that optimum concentrations or amounts of reaction parameters were composed of 25ng of template DNA, 5pM of 10-mer primer, 0.05mM of dNTP, and 0.25 units of Taq DNA Polymerase in 50㎕ of the final reaction mixture. In this study, random primer A_(9)∼A_(14)(Operon) were selected as proper primers for tomatoes. 45 cycles of PCR and the annealing temperature of 38℃ were proper to get enough amount of amplified DNA for clear polymorphic band formation. The results also indicated that the concentrations or amounts of reaction parameters were highly correlated with each other in their effects on DNA amplification.

본 연구에서는 연약지반개량공사가 실시된 광양지역을 대상으로 압밀기간동안 개량지반의 물리적, 역학적 변화특성 및 개량효과를 고찰되어 있다. 지반개량전 원지반에서 시료를 채취하고, 모래말뚝 타설직후, 압밀방치중(예상압밀도 50%) 및 압밀완료시(예상압밀도 90%)에도 시료를 채취하여 각각 토질정수를 조사 비교하였다. 그 결과 압밀이 진행되는 동안 지반의 강도는 증가하여, 일축압축강도로 구한 점성토지반의 강도증가율(C_u/P_o)이 0.36이 되었다. 그리고, 일축압축강도로 구한 점성토지반의 강도증가율(C_u/P_o)이 0.36이 되었다. 그리고, 일축압축강도와 함수비는 최대압밀응력에 대하여 유일함수관계를 보이고 있으며, 압밀완료시점(예상압밀도 90%)에서 추정된 비배수전단강도는 측정된 비례수전단강도와 비교적 잘 일치한다. In this study, both physical and mechanical properties of soft grounds are investigated during improvement works of soft grounds in Kwangyang. The properties of soil before ground improvement are compared with the properties of the improved ground after Sand Compaction Pile installation, during consolidation(degree of consolidation 50%), and at the end of consolidation(degree of consolidation 90%). From this result, improvement of the shearing strength of soft grounds can be deserved during consolidation, and the improving rate of shearing strength C_u/P_o is 0.36. The relationship between the shearing strength by unconfined compression tests, consolidation stress and water content shows that both the shearing strength and water content have an unique function relationship. The shearing strength predicted by Rutledge hypothesis shows relatives good agreement with the field strength.
