As high-precision parts are needed with manufacturing techniques improved, the demand of high-precision machine tools has been increasing. They are made to develope the precision measuring skill to maintenance the accuracy of themselves as a matter of course. We on the paper measured straightness and squareness of the square to verify that it is possible for CT(circular test) method by 2-dimensional probe and the square to measure squareness. Furthermore, we compared the result of the study with the computer simulation's to prove its possibility, and made an improvement of measuring method.

The incidence of coexisting hyperparathyroidism and empty sella syndrome is rare and the etiology and incidence of their coexistence is not known. The association of hyperparathyroidism and the empty sella syndrome may be related to multiple endocrine neoplasia (MEN) syndrome due to a genetic disorder. We experienced a rare case of hyperparathyroidism presenting as acute pancreatitis combined with empty sella. We report here a 37-year old female who manifested epigastric pain because of acute pancreatitis. She had hypercalcemia due to parathyroid adenoma. A pituitary gland was not visible in the sella turcica on MRI scans. On genetic analysis, she did not show a mutation of the MENIN gene. Empty sella is thought to be a coincidental finding with hyperparathyroidism.

A Syntactic Construction has semantic and syntactic function. However, in Korean Language, there can be a syntactic construction without these two functions. If one of those is dependent form, then the structure is called catenative construction. Catenative construction is classified into "verb-catenative" and "noun-catenative" according to its dependency. There are following distinctions in verb-catenative construction. a. subject-predicate disconformity b. inability to insert adverbs c. inability to use partial anaphora d. inability to use partial movement e. acquirement of grammatical function. And then, in noun-catenative construction. a. no modification properties b. ability to maintain the tense c. ability to maintain the predicate function.

The problem of automobile body corrosion has been addressed over the past decade by the increasing use of zinc and zinc coated steels in automotive application. This paper discribes the evaluation of formability and painted corrosion performance of galvalume steel sheet. This paper presents an overview of the program and some initial test results on the weldability, lifetime of the electrode tip shape of the spot welding and corrosion protection, Galvalume steel sheet improved corrosion performance and spot weldability of galvalume steel has no problem for the variation of welding current. And tip lifetime was changed according to the influence of shape.

This study is an investigation for the ADS optimum design using FEA. We write out program which express ADS perfectly and reduce the required time for correcting of model to the minimum in solution and manufacture result. We complete algorithm which can plan optimum forming of model by feedback error information in CAE. Then we correct model by feedback date obtaining in solution process, repeat course following stress solution again and do modeling rachet wheel for optimum forming. That is our aim. In rachet wheel, greatest equivalence stress originates in key groove comer and KS standard is proved the design for security.

This study investigates the practical aspects of Dongs?sataek Lone(東 ·西四宅論), korean traditional housing. Dongsasataek Lone is a theory that lay of house and gate tells fortunes, and it is composed of Dongsataek(north, east, southeast, south) and Sasataek(northeast, northwest, west, southwest). Dongs?sataek Lone contains as follows : (1) A house in Dongsataek(north, east, southeast, south) have to gate Dongsataek. And in the case of a house in Sasataek(northeast, northwest, west, southwest) have to gate S?sataek. (2) Anchae(a place for women) have not to be seen through clearly and trespassed for privacy. (3) A gate in northwest is not so good for seasonal wind of winter. (4) A house facing south is the best disposition, and then a house facing southeast, southwest, or east is good anyway. But a house facing north, northeast, northwest, or west is not so good. And, in this research, a compass put the center of a court. Accordingly, Dongs?sataek Lone can be applied practically to a contemporary house planning.

It is the purpose of this study to investigate the possibility and mechanisms of complex formation for the removal of cyanide and toxic heavy metals from mining and electroplating industrial wastewater simultaneously. The adsorption forms of heavy metals from a synthesized wastecyanide water by activated carbon is discussed. Under the cyanide complexiation, mercury ion is adsorbed in the formation of complex anion as ?? and Hg(CN)₃, but zinc and cadmium are also as ?? and ?/?. The effects are established under the presence of ?? in the concentration range ?? mol/ℓto ?? mol/ℓand the presence of heavy metals.

This study is to evaluate the tool performance in honing using diamond reamer and present grounds whether the localized products are sufficiently competitive comparing with the existing imported ones. The heads of the tool performance evaluation are roundness, roughness, tool life of the workpiece and so on. When evaluating the tool performance, cutting process is divided by three areas which are rough, semi-finish and finish cut. Honing improves the accuracy such as boring and reaming after manufacturing the inside diameter, and finishing directly by boning is a recent trend. This honing is used greatly in hard cutting materials like cemented carbides and it is the CBN and diamond that is used in hard cutting materials. Both of them are expensive and most of them are imported.

Streptozotocin was injected to rats to induce the experimental diabetes mellitus. In order to find out the effect of diabetic treatment by experimental method, Palmiwon and Gliclazide were administrated to observe the change of blood sugar, body weight, the weight of organ and alkaline phosphatase. And thus, the result was as follows. 1. The blood sugar level of diabetic rat was decreased after administration of Palmiwon with Gliclazide. 2. Body weight of diabetic rats was decreased after administration of Palmiwon with Gliclazide. 3. The levels of kidney alkaline phosphatase were recovered by administration of Palmiwon with Gliclazide.
