The present paper is concerned with the notions of Lipschitz and asymptotic for perturbed functional differential system knowing the corresponding stability of functional differential system. We investigate Lipschitz and asymptotic stability for perturbed functional differential systems. The main tool used is integral inequalities of the Bihari-type, and all that sort of things.

Three simple carboxamides incorporating the phenethylamine moiety have been isolated from strain XR-NC of a symbiotic bacterium Xenorhabdus nematophilus. Their structures were identified by spectroscopic data and synthesis. The compounds exhibited significant cytotoxicities against human cancer-cell line, viz. the gastric adenocarcinoma, colon adenocarcinoma and lung adenocarcinoma.

Primary extranodal bone lymphoma involving the peripheral extremities is extremely rare. Here, we report a definitive case of diffuse large B-cell lymphoma involving the phalangeal bone of the 3rd finger. Systemic evaluation revealed the lesion as the only site of lymphoma involvement.

Three new species of poecilostomatoid copepods are described as associates of the scleractinian coral Gardineroseris planulata (Dana) from the Moluccas: Sociellus geminus n. sp., Odontomolgus mucosus n. sp. and O. unioviger n. sp. The genus Sociellus is transferred from the Rhynchomolgidae to the Anchimolgidae. The previously described four species of the genus Paramolgus (P. angustus, P. eparmatoides, P. gibberulus, and P. setellus) of the Rhynchomolgidae, associated with Gardineroseris planulata, are transferred as well to the genus Anchimolgus in the Anchimolgidae.

Ergasilus zacconis (Yamaguti, 1936), the copepod parasite originally named as Pseudergasilus zaconnis, is redescribed based on the specimens newly collected from the freshwater fish Zacco platypus (Temminck and Schlegel) from Japan. Some errors appearing in the original description are emended. An explanation for the generic position of this species is given.

The purpose of this research is to investigate the synergistic effect of herb medicines with hydrocortisone and the regulation effect on the immune system of Onbitang and Dangguijakyaksan at the supernatant of PHA-P stimulated PBMC in the patients with minimal change nephrotic syndrome(MCNS). From the measurement of the concentration rate of IL-4, sCD23 and IL-13, the experiment yielded the following results : The Onbitang group showed a greater tendency to suppress IL-4 and IL-13 levels in MCNS group with no statistical significance. It showed very strong suppression in soluble CD23 compared with control group in MCNS group. The Dangguijakyaksan group, though not statistically significant, was inclined to suppress IL-4 level in MCNS group. It shows stronger suppression in sCD23 and IL-13 levels than these of control group in MCNS group. As for the synergistic effect, the group of hydrocortisone with herb medicines(Onbitang or Danguijakyaksan) produced more suppressive effect to IL-13 level in MCNS group than that of hydrocortisone-only group. They also tended to suppress sCD23 and IL-4 levels, though no statistical significance can be given. As to the suppressive effect of 1L-13 level, the group of Onbitang with hydrocortisone showed an increase of 22.6%, while the group of Dangguijakyaksan with hydrocortisone showed 14.7%. So Onbitang is more effective than Dangguijakyaksan. From the above results, a combinative treatment(herb medicines with hydrocortisone) can be an alternative method to substitute for steroid therapy. It can be a more effective therapy than steroid-only therapy because it is expected to reduce side effects and it shows more special effect to suppress IL-13 level. Based on the present results, further investigation concerning the serum IgE elevation is needed.

In this experiment, the effects of Pueraria thunbergiana extracts on the activation of immune cells were studied. An immune cell-activating factor was partially purified from P. thunbergiana by means of physiological saline extraction, acetone precipitation, and heating inactivation. P. thunbergiana extracts increased the proliferation of spleen cells and induced the production of IL-2, IL-6, TNF-${\alpha}$, and IFN-${\gamma}$ by spleen cells. Also, they increased the proliferation of purified B cells and the production of IgM antibody in a dose-dependent fashion. The extract self-induced NO synthesis in a mouse macrophage cell line (RAW264.7). When cell lines were treated with extracts, the cytokines' (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) production was markedly increased. Therefore, P. thunbergiana extract can self-activate spleen cells, B cells, and macrophages. These results might be useful in further studies into a possible immune-activating agent derived from P. thunbergiana for the development of functional foods and drugs.

Background: To compare the anesthetic efficacy of supplemental buccal infiltration (BI) (1.7 ml) versus intraligamentary (IL) injection containing 0.4 ml of 4% articaine with 1:100.000 epinephrine after an inferior alveolar nerve block (IANB) with 1.7 ml 2% lidocaine in the first and second mandibular molars diagnosed with irreversible pulpitis (IP). Methods: One hundred subjects diagnosed with IP of either the mandibular first (n = 50) or second molars (n = 50) and failed profound anesthesia following an IANB were selected. They randomly received either the IL or BI techniques of anesthesia. Pain scores on a 170 mm Heft-Parker visual analog scale were recorded initially, before, and during supplemental injections. Furthermore, pulse rate was measured before and after each supplemental injection. During the access cavity preparation and initial filing, no or mild pain was assumed to indicate anesthetic success. The chi-square test, Mann-Whitney U test, and independent samples t-test were used for the analyses. Results: The overall success rates were 80% in the IL group and 74% in the BI group, with no significant difference (P = 0.63). In the first molars, there was no significant difference between the two techniques (P = 0.088). In the second molars, IL injection resulted in a significantly higher success rate (P = 0.017) than BI. IL injection was statistically more successful (P = 0.034) in the second molars (92%) than in the first molars (68%). However, BI was significantly more successful (P = 0.047) in the first molars (88%) than in the second molars (64%). The mean pulse rate increase was significantly higher in the IL group than in the BI group (P < 0.001). Conclusions: Both the IL and BI techniques were advantageous when used as supplemental injections. However, more favorable outcomes were observed when the second molars received IL injection and the first molars received BI.

허블우주망원경에 장착된 ACS/WFC로 획득한 Anderson 등과 Sarajedini 등의 깊고 균질한 VI 측광 목록을 이용하여 우리은하 구상성단 M13(NGC 6205)과 M22(NGC 6656)의 뜨겁고 밝은 백색왜성 탐사를 수행하였다. 허블우주망원경 VI 측광 목록으로부터 M13과 M22의 V 대 V-I 색-등급도를 작성하였고 여기에서 많은 항성으로 잘못 검출된 대상(spurious detection)을 측광 질매개변수 qfit(V)와 qfit(I)에 따라서 제거하였다. 그리고 M13의 경우에는 중심의 높은 밀집도에 기인한 높은 측광오차를 가진 중심영역 별을 제거하기 위하여 성단 중심으로부터의 추가적인 반경 제한을 실시하였다. 이렇게 도출한 M13과 M22의 각각의 V 대 V-I 색-등급도에서 십여개 정도의 백색왜성 후보를 동정하였다. 이들은 동반되어 제공되는 ACS/WFC 각각의 영상에서 항성체로 동정되었으며, M13과 M22의 성단 중심부 영역에 임의적으로 분포하고 있으며, 색-등급도상의 위치가 DA 백색왜성 냉각계열의 밝은 부분에 위치하고 있어서 이들이 M13과 M22의 진짜 백색왜성임을 나타내고 있다. 이들에 대해 추가적으로 분광학적인 관측 연구를 수행한다면 이들의 백색왜성 진위 여부와 다양한 물리량을 밝혀낼 것이다. 또한 가까운 구상성단에 대해서 같은 방법으로 조사를 수행하면 더 많은 구상성단에서 갓 태어난 뜨겁고 밝은 백색왜성을 찾아낼 것으로 기대한다.

22.9kV 가공배전설비 진단방법으로 고주파, 초음파, 열화상, 광학, 활선기별점검이 대표적으로 적용되고 있다. 진단장비로 적출된 가공 배전설비는 광학진단이나 활선기별점검을 통해 기자재의 외관상태등을 최종적으로 확인한다. 활선기별점검은 고(高)비용이며 활선작업차(화석에너지), 활선자격, 다수인원이 필요하고 하천횡단, 장경간, 장척전주, 진입곤란개소 등은 진단점검이 곤란하며 광학진단은 기자재 상부를 진단 할 수 없다는 제약이 있다. 본 논문에서는 항공 원격제어 헬기를 통해 22.9kV 가공배전선로에 근접하여 기자재 상태 확인 방법을 최초로 적용하여 기존의 활선기별 점검 및 광학진단 점검의 문제점을 해소하는데 효과적이었으며, 비용절감과 안전확보, 기존방법에서 점검이 곤란한 사항도 해소는 물론 Green Energy정책에 기여할 수 있었다.
