With the development of Yanbian tourism and entering from all directions of foreign enterprises, which will have a great impact on the development and management of tourism human resources in China. As Yanbian tourism develops rapidly in recent years, the demand for tourism human resources has a rapid expansion. However, the development and management of human resources is relatively backward, which has seriously limited the development of Yanbian tourism and needs to be solved as soon as possible. Therefore, this paper elaborates the human resources of Yanbian, analyses the problems about the development and management of human resources, and then finds that the total quantity of Yanbian human resources is insufficient, whose personnel training has a great gap compared with its market demand;its quality and level as a whole is somewhat low; professionals of tourism and hotel management are deficient;training work falls behind, which can not satisfy the tourism demand;incentive mechanism is on shortage, which leads to a frequent flow of personnel;employees have a weak sense of service. Then, it constructed a “Trinity” pattern of human resources development and management in Yanbian tourism. This paper puts forward practical countermeasure and measures from 6 aspects of establishing the correct concept of tourism talents, letting local governments and tourism administration departments play a leading role sufficiently, improving and strengthening the tourism human resources training, improving Yanbian tourism education system, building perfect talent and incentive mechanism, strengthening the occupation career management of tourism enterprise employee and so on, which provides theoretic and practical reference for the scientific development of human resources in Yanbian. 旅游业的持续快速发展以及国外旅游企业的全方位进入,将对中国旅游人力资源开发与管理 带来极大的冲击。近年来延边旅游业迅猛发展,旅游业对人力资源的需求急剧膨胀,但是,旅 游人力资源的开发与管理的相对滞后,严重制约着延边旅游业的发展,需要迅速加以解决。因 此,本文首先阐述了延边旅游人力资源的现状,分析了旅游人力资源开发与管理中存在的问 题,发现了延边旅游人力资源总量相对不足,人才培养滞后于市场需求;整体素质及层次偏 低;旅游及酒店管理专业人才匮乏;培训工作落后,不能满足旅游业的需求;缺乏有效的激励 机制,人员流动频繁;从业人员服务意识薄弱。然后,构建了延边旅游业“三位一体”人力资源开 发与管理模式。最后,提出了树立正确的旅游人才观念、充分发挥地方政府和旅游行政管理部 门的指导作用、完善和加强旅游人力资源培训、改善延边旅游教育体系、建立完善的人才使用 和激励机制、强化旅游企业员工职业生涯管理等6个方面提出了切实可行的对策和措施,为延边 旅游企业人力资源的科学发展提供理论与实践。鉴。

Compact Wideband Open-End Slot Antenna With Inherent Matching
Zhe-Jun Jin,Tae-Yeoul Yun IEEE 2014 IEEE antennas and wireless propagation letters Vol.13 No.-
<P>A compact wideband open-end slot antenna is proposed for DCS, PCS, UMTS, WLAN, and WiMAX band applications. The antenna is composed of an open-ended slot and a central line within the slot. The open-end slot decreases the antenna size in half, compared to a conventional slot-ring antenna. Furthermore, the narrowed slot and central line miniaturize the antenna and obtain wideband performance using the inherent impedance-matching network of the central line. The proposed antenna obtained an omnidirectional radiation pattern with an antenna gain of larger than 1 dBi and an antenna efficiency of greater than 50% over 1710-3660 MHz.</P>

Background: Making the distinction between large cell neuroendocrine carcinoma (LCNEC) and small cell lung carcinoma (SCLC) is difficult in some samples of biopsy tissues, but we have to separate LCNEC from SCLC because the two types of cancer may need different therapy and they have different prognostic implications. Thus far, there are no specific immunohistochemical markers that allow distinguishing these two kinds of tumors. Methods: We performed an immunohistochemical analysis to study the expressions of p63, Bcl-2, and 34βE12 and to investigate whether these 3 molecules have correlations in LCNEC and SCLC. We also evaluated the expression of the neuroendocrine markers chromogranin, synaptophysin and CD56. Results: A statistical analysis was performed for p63, Bcl-2, and 34βE12 in separate and combined panels. According to the combinations of p63, Bcl-2, and 34βE12, there were frequent expressions of p63-/Bcl-2+ or Bcl-2+/34βE12- in the SCLC, and there was a superior proportion of them in the SCLC rather than that in the LCNEC. The p63-/Bcl-2+ and Bcl-2+/34βE12- antibody combinations showed higher specificities compared to any single antibody for diagnosing SCLC. Conclusions: Bcl-2 and selective p63 or 34βE12 made up a most useful panel of markers for making the differential diagnosis of LCNEC and SCLC.

本研究以长春市制造业4家公司的286名员工为有效样本, 探讨了情绪智力对工作压力和工作倦怠的影响的问题。研究在理论背景的基础上提出了研究假设和研究模型, 然后采用了结构方程建模(structural equation modeling: SEM)的方法, 验证了事先提出的研究假设。结果表明, 组织成员的情绪智力对工作压力有着显著负面影响, 对工作倦怠的两个维度(消极怠慢和成就感低落)有着显著负面影响, 工作压力对工作倦怠的三个维度(情绪衰竭、消极怠慢和成就赶低落)有着显著正面影响。从而得知, 工作压力在情绪智力和情绪衰竭的关系中起到完全中介效应;在情绪智力和工作倦怠的两个维度(消极怠慢和成就感低落)的关系中起到部分中介效应。 This study is based on empirical study includes 226 organization middle managements of 5 manufacturing companies in Chang Chun, China. This study performs experimental examination of the effect of Emotional Intelligence on the Job Stress and Job Burn-out. Based on theories’ background, this paper developed the study model and framed hypothesis. The data is analyzed by using structural equation modeling(SEM). The results showed that Job stress was a full mediator of the relationship between emotional intelligence and job burnout whereas Job stress partially mediated the relationship of emotional intelligence with cynicism and reduced personal accomplishment. This implied that the mechanism of the effects of emotional intelligence on emotional exhaustion was different from that of the influence of emotional intelligence on cynicism and reduced personal accomplishment.

본 연구는 중국 베이징에 있는 노동조합이 결성되어 있는 제조업체의 조합원 420명을 대상으로 노사관계 행위 주체의 역할 특성이 협력적 노사관계 분위기와 종업원들의 파업의향에 미치는 영향을 구조방정식 모형(Structural equation modeling: SEM)을 이용하여 그 효과를 분석하였다. 분석 결과, 첫째, 종업원들이 노조와의 정보공유, 분배적 공정성과 절차적 공정성, 통합적 협상과 노조수단성, 의사결정참가 정도를 높게 지각할수록 협력적 노사관계 분위기가 높은 것으로 나타났다. 둘째, 종업원들이 노조와 정보공유, 분배적 공정성, 절차적 공정성, 통합적 협상, 그리고 의사결정참가 정도를 높게 지각할수록 파업의향은 낮은 것으로 나타났다. 셋째, 협력적 노사관계 분위기는 파업의향에 영향을 미치지 않는 것으로 나타났다. 이러한 연구 결과를 바탕으로 노사협력에 관한 실무적 시사점과 향후 연구에 대한 논의가 이루어졌다. In this study, the effect of industrial relations actors' role characteristics on cooperative Industrial relations(IR) climate and strike intention is investigated for 420 employees of Chinese manufacturers located in Beijing, China. Using a structural equation modeling (SEM). it is found that, firstly, the Chinese workers perceived more cooperative IR climate when the employees have higher perception about information sharing amongst union and employers, distributive justice and procedural justice, integrative bargaining, union instrumentality, and participation in decision making. Secondly, strike intention is low when the employees have higher perception about information sharing with union, distributive justice, procedural justice, integrative bargaining, and participation in decision making. Thirdly, we could not find evidence that cooperative IR decreases the strike intention of the employees. This part is left for further investigation whether there are any particular mechanism with Chinese workers. Furthermore, the implications for practice and future research are discussed.

Synthesis of 6-Alkyloxyl-3,4-dihydro-2(1H)-quinoliones and Their Anticonvulsant Activities
Quan, Zhe Shan,Wang, Jun-Min,Rho, Jung-Rae,Kwak, Kyung-Chell,Kang, Hee-Cheol,Jun, Chang-Soo,Chai, Kyu-Yun Korean Chemical Society 2005 Bulletin of the Korean Chemical Society Vol.26 No.11
A series of 6-alkyloxyl-3,4-dihydro-2(1H)-quinoliones (5a-5n) were synthesized through nitration, reduction, diazotization, hydrolysis and alkylation from 3,4-dihydro-2(1H)-quinolione. Their structures were characterized by IR, $^1H$-NMR and MS. The anticonvulsant activity was evaluated by the Maximal electroshock test (MES) and the subcutaneous pentylenetetrazole (Metrazole) test (sc-Met). The neurotoxicity was measured by the Rotarod test (Tox). The result showed that 6-hexyloxy-3,4-dihydro-2 (1H)-quinolinone (5c) was potent in anti-MES and anti-scMet test with $ED_{50}$ of 24.0 mg/kg and 21.2 mg/kg, respectively, albeit its $TD_{50}$ (67.6 mg/kg) revealed the high neurotoxicity. 6-Benzyloxy-3,4-dihydro-2(1H)-quinolinone (5f) was less effective against MES induced seizure with $ED_{50}$ of 29.6 mg/kg, but no neurotoxicity was observed even under 300 mg/kg. Its Protective index (PI) was greater than 10 preferable to Phenytoin, Carbamazepin, Phenobarbital and Valproate.

Purpose: To determine whether microRNA could be a therapy target of erectile dysfunction (ED) and the underlying mecha-nisms. Materials and Methods: Eight-week-old fasting male SD rats were intraperitoneally injected with streptozotocin to construct diabetic rat models. Diabetic ED rats were treated with miRNA-92a inhibitor. The cavernous nerves were electrically stimu-lated to measure the intracavernous pressure and mean arterial pressure of rats in each group. After the detection, the penile cavernous tissues are properly stored for subsequent experiments. Rat aortic endothelial cells were used in in vitro studies. Results: The expression of miR-92a was significantly increased in the corpus cavernosum of Streptozocin (STZ)-induced di- abetic rats and injection of miR-92a antagomir into the corpus cavernosum of diabetic rats significantly increased eNOS/NO/ cGMP signaling pathway activities, cavernous endothelial cell proliferation, endothelial cell-cell junction protein expression and decreased the levels of oxidative stress. These changes restored erectile function in STZ-induced diabetic rats. Moreover, in vitro study demonstrated that the miR-92a expression increased significantly in endothelial cells treated with high glucose, inhibiting AMPK/eNOS and AMPK/Nrf2/HO-1 signaling pathways in rat aortic endothelial cells via targeting Prkaa2, causing endothelial dysfunction and overactive oxidative stress, miR-92a inhibitor can improve the above parameters. Conclusions: miRNA-92a inhibitor could exert an inhibition role on oxidative stress and endothelial dysfunction to improve diabetic ED effectively.
