The study on Uredinales of Korea was initiated by P. Hennings in 1899. After that abundant works were done by Naohide Hiratsuka. And Seiya Ito, P. & H. Sydow, K. Nakata, S. Takimoto, A.L. Jaczewsk, V. L. Komarov, W.A. Tranzschel and others also engaged in the research on this field. Since 1956 the author has collected the specimen in South Korea, chiefly around Prov. Kangwon, among which are found 12 species 4 genera of rusts and 22 species of additional hosts all unrecorded from Korea. The author has described in the paper 220 species 32 genera 3 families of rusts in Korea, including those collected, by this author. This works, it must be added, owe much to the literatures of Dr. Naohide Hiratsuka, Prof. of Tokyo University of Education. The author express his hearty thanks to him.

Contributions by Tsai Lun, the paper inventor, are as follows; 1. As most of the materials, which were used, were the waste articles, the cost was cheap and the large quantity could be produced at a time. 2. It was much more convenient to use or carry them beyond comparison with the existing materials. 3. He established how to manufacture the paper if which the materials is vegetable fiber and invented a successive paper making. 4. He extended the kinds of paper manufacturing materials by instructing the worker about how to make the bark paper from the paper mulberry fiber, namely, he tried to realized the technological renovation to connect the past and the future. 5. As a result of his efforts, he greatly contributed to the social development as the supply of books and knowledge was smoothly active, and the paper is the best and ultimate one as the writing material.

It is generally recommended to use EVM as an efficient means for measuring project performance and progress so that the EVMS user could manage his project successfully. In spite of it's favorable intention, most project participants think it as a heavy load or a sub practiced job with low responsibility. Even though there are lots of variables triggering unpredictable troubles in EVM application, EVM still could be a valuable project health indicator. In this paper we introduce a performing method for EVM based on system engineering process.

The president of NSPE(2009-2010), Mr. Grossman had attended the The 3rd National Conference for Professional Engineers of Korea in accordance with the mutual agreement between KPEA and NSPE. He then, had a chance to present to our professional engineers about the licensure of professional engineers and engineering education of USA. The main contents of his presentation were introduction of the current situation of professional engineer system and needs to apply this licensure to the industry and education field, needs to strengthen the engineering education and needs to collaborate with Government in oder to open employment visa for foreign engineers. In the meantime, we should make use of this chance of engineer shortage in USA and let more Korean engineers work successfully in USA.

Patients with unilateral cleft lip and palate (UCLP) usually present unilateral cross bite due to collapse of the maxillary minor segment. Unequal expansion of the palate is needed to resolve this problem in UCLP patient. Unilateral segmental palatal distraction (USPD) after Le Fort I osteotomy and the oblique placed orthodontic expansion screw (Hyrax) can be used to correct the unilateral cross bite. 1his case report describes the effects of USPD of the collapsed maxillary minor segment on patient with unilateral cleft lip and palate.

In a dynamic game where the players move in a periodical sequence, each player observes the strategy of the others. So the players who move later in a game get to know the moves of others having made before them. Those who move earlier must take this into account in devising their optimal strategy. In the Poolco model, the bidding game is executed periodically. The player participating in the bidding game accumulates the information of its own and others'strategies, and payoffs through the repeated bidding process. Thereby, the players in this game would be able to map out how get the maximum profit, and get closer to the optimal strategy. This paper presents a mathematical modeling for a player to determine his or her optimal strategy at period T, based on the information acquired from the previous rounds for the periods, T-1, T-2, and so on. The proposed modeling is demonstrated with a dynamic fame theory.

A 61-year-old man with an antecedent febrile illness presented with progressive flaccid paraparesis, but no sensory or sphincter involvement. Magnetic resonance imaging (MRI) of the spine was negative and nerve conduction study (NCS) showed the absence of F-waves in his legs, suggesting $Guillain-Barr{\acute{e}}$ syndrome (GBS). However, abdominal pain after admission led to the consideration of the spinal cord ischemia secondary to aortic dissection confirmed by computed tomography. We report the rare condition of painless aortic dissection simulating GBS.

Decision making is a function of many variables, but among these, human burden (soft-ware) and machine burden (hard-ware) are critical. Decision Maker is rather concerned with the soft-ware and just wants to have machine calculate the quantitative arithmetic involved in the decision-making study, because he is responsible for that decision whether or not he knows details about the techniques used by his staffs. From the point of these considerations, computer-assisted war game model has its significance in military decision making. The major outcome of this model is time-phased FEBA movement. FEBA is moved mainly by the ratio of the Index of Combat Effectiveness (ICE). To calculate ICE, Ground Forces are concerning the Index of Firepower (IFP) of individual weapons and in the case of Air Force, sorties are allocated into each sector, and added to the Ground Force IFP. With the ratio of total ICE, FEBA is moved according to the War Game Tables and process is repeated after consideration of casualties. This model is used by IBM-370/135 in MND computer room and also tested by IBM-3741/3717 established at ROKA HQ.

A red pigment was formed when heating dehydroascorbic acid in the presence of ${\alpha}-amino$ acids and thought to be an intermediate amino-reductone in the Strecker degradation. The reaction of pigment formation can be kinetically expressed as two-step consecutive first-order in the presence of excess of ${\alpha}-amino$ acids. The reaction rate constants were successfully determined by employing various amino acids (L-His., L-Gly., L-Thr., L-Ser. ) at different pH. The results suggested the formation of the red pigment was most favorable at the pH 5.0.

Association rule mining searches for interesting relationships among Items in a given database. Association rules are frequently used by retail stores to assist in marketing, advertising, floor placement, and inventory control. There are three primary quality measures for association rule support and confidence and lift. In this paper we present association rule mining based antecedent variables. We call these rules to antecedent association rules. An antecedent variable is a variable that occurs before the independent variable and the dependent variable. For example, in politics, a special interest group may want to support a politician who backs their cause. The group would look for a candidate who supports their views and support his election. Once in office, the politician would then conduct policy that supports the interest group.
