  • Purpose: To investigate the impact of hyperglycemia during inductive treatment on the prognosis of acute lymphocytic leukemia (ALL) in children. Materials and Methods: Clinical data of 159 ALL childhood cases were reviewed. The patients were divided into the hyperglycemia group (fasting $glucose{\geq}126mg/dl$ and/or random blood $glucose{\geq}200mg/dl$) and the euglycemia group according to the blood glucose values. The X2 test was performed to compare the complete remission rates of the two groups, and Kaplan-Meier and log-rank tests were performed to compare the 5-year overall and relapse-free survival. Results: The incidence of hyperglycemia in the $age{\geq}10-year-old$ group was higher than the younger-age group (P=0.009). Values in the interim- and high-risk groups were higher than the standard-risk group (P=0.028), while there was no significant difference between genders (P=0.056). The complete remission rates of the 2 groups demonstrated no significant difference (P=0.134), while the 5-year OS of the hyperglycemia group was lower than in the euglycemia group ($83.8{\pm}6.0%$ vs $94.9{\pm}2.4%$, P=0.014). The 5 -year RFS was significantly lower than the euglycemia group ($62.9{\pm}8.7%$) vs $80.2{\pm}9.1%$, P<0.001). Conclusions: Children with $age{\geq}10year$ old, and in the middle- and high-risk groups appear prone to complicating hyperglycemia during inductive chemotherapy, associated with lower 5-year OS and RFS.

  • The informative or important entities in utterances are focused and the focused items are usually accompanied by changes in phonetic manifestation. Phonetic realizations triggered by focus include changes of tonal contours as well as segmental strengthening. Focus in Korean is characterized by new phrase initiation, dephrasing, and initial tone contour with an enlarged pitch range in addition to segmentally lengthened initial segment. Focusing on the prosodic cues which play an important role in delivering the speakers' intention, this study aims to find out what intonational characteristics of Korean focus are realized by English learners of Korean. The English learners are divided into two groups according to their fluency in Korean, and the differences in focus realization between each group are discussed. Furthermore, the phonological and phonetic realizations of focus by English learners of Korean are compared to those by Korean native speakers. The results of this study yields two suggestions for Korean intonation education of L2 learners. First, the comparison between the two speaker groups can give better understanding in how and why the Korean intonation of English speakers is different from that of Koreans. Second, each phonological and phonetic characteristic of focus realization can weigh differently and its realization provides a criterion for evaluation of L2 Korean proficiency.

  • We examined the feeding habits of larval Clupea pallasii using 148 specimens collected from December 2010 to April 2011 in the Nakdong River estuary, Korea. We found that larval C. pallasii [8.3-26.0 mm NL (notochord length)] are carnivorous, consuming mainly copepods, rotifers, cirripeds, and free-living flatworms (Macrostomida). Their diet also include small quantities of shrimp nauplii, tintinnids, cladocerans, and larval bivalves, among other food sources. To evaluate ontogenetic changes in dietary composition, we split larvae into four size groups: 8-12 mm, 12-16 mm, 16-20 mm, and > 20 mm NL. Rotifers were the most important prey items for the smallest group, but all other groups predominantly consumed copepods. The largest group frequently preyed on rotifers, cirripeds and flatworms, in addition to copepods. Larvae also showed bi-modal feeding, with peaks in the late afternoon and at midnight, wherein the mean number of prey per individual peaked at 1,800-1,900 h.

  • The purpose of this study is to investigate the visual sensibilities of brassiere design. Brassieres were divided into three types according to connection of a cup and a strp. In each type Lace was used where the part of the cup divided by Lines which were constructed such as a mold a horizontal a vertical a mixed and an oblique design. As a result 39 brassieres were obtained. The experiment has been done for seven groups which were divided by the type line and lace with 5 semantic differential bi-polar scales and 10 specialists. The data was analyzed using the statistical SPSS package. The major findings of this research were as follows. An oblique design line in the brassiere were effective in making the breast look bigger more buxom and more voluminous. To make the breast look small and unvoluminous the use of a mold in the 1/2 cup brassiere was effective. Also a mold using lace ion the 1/2 cup brassiere had an effect in making the breast look flatter and broader.

  • This paper presents an efficient monitoring method of a network protocol for a downloadable conditional access system (DCAS) that can securely transmit conditional access software via a bi-directional communication channel. In order to guarantee a secure channel based on mutual authentication between a DCAS head end server and set-top boxes, DCAS messages are encrypted and digitally signed. Owing to applied cryptographic algorithms, it is impossible to get information from messages directly without additional processing. Through categorizing DCAS messages into several groups, the proposed monitoring method can efficiently parse and trace DCAS messages in real-time. In order to verify the stability and effectiveness of the proposed monitoring method, we implement a DCAS monitoring system capable of capturing and parsing all DCAS messages. The experimental results show that the proposed monitoring method is well designed.

  • To develop more advanced binaphthol derived CSPs, two new 1,1-bi-2-naphthol derived chiral stationary phases (CSPs) (CSP 1 and CSP 2) were prepared by connecting with silica gel at a hydroxy (OH) group of binaphthol. Previously reported two 1,1'-binaphthyl-2,2'-diamine derived CSPs (CSP 3 and CSP 4) were also prepared to compare the role of their functional groups (-OH and -$NH_2$) with CSP 1 and CSP 2. Enantioseparation of randomly selected, 11 chiral compounds on these four CSPs was performed and the results compared to each other. 3,5-Dinitrobenzoyl (3,5-DNB) derivatives of each CSP showed better results than the others and binaphthyldiamine derived CSP showed slightly better than binaphthol derived one.

  • The mutual separation behavior of actinides and rare earths in a countercurrent multistage reductive extraction system was predicted by computer calculation. The distribution information for actinides and rare earths in the reductive extraction systems of LiCl-KCl/Cd and LiCl-KCl/Bi was collected from literature and then it was used for the calculation of a multistage extraction. The results of the concentration profiles throughout the extraction cascade, recovery yields of various metal solutes, and separation factors between the actinides and rare earths were calculated. The effects of the major process parameters, such as reducing agent content in the metal phase, number of stages, and salt/metal flow ratio, etc., on the extraction behavior were also examined.

  • This paper proposes a new solution to support Internet Multicast for mobile hosts. The proposed algorithm is based on the remote subscription approach of IETF Mobile IP that mobile node re-subscribes to its desired multicast groups while at a foreign network. In addition, we adopt the bi-directional tunneling to minimize the disruption of multicast service due to movement of a host from network to another. This paper also analyzes the handoff latencies and data packet loss amount of our algorithm and compares to other approaches. Our analysis shows that the proposed algorithm has good robustness, scalability and routing efficiency.

  • Shape memory materials are widely used in high-tech industries. Although shape memory polymers have been developed, they have a disadvantage, only unidirectional resilience. Shape memory polymers with bi-directional recovery resilience have been actively studied. In this study, a bidirectional shape memory polyurethane was synthesized using poly(${\varepsilon}$-caprolactone) diol, methylene dicyclohexyl diisocyanate, and hydroxyethyl acrylate. The first physical curing occurred between hard segments and hydrogen bondings when the solution was dried. The second curing in acrylate groups was performed by UV exposure. A degree of curing was analyzed by infrared spectroscopy. The shape memory properties of 2 step-cured polyurethanes were investigated as a function of UV curing time.
