This study aims to provide a theoretical base for making a character education program on "how primary school students to cultivate their own right and good-minded characters." This study consists of three approaches: 1) an integrative approach based on the social and emotional learning, 2) development of integrative programs articulating three key domains directly and indirectly influencing students' character formation - school, family and local community(society), 3) maximum use of the educational institutes' moral education curriculums and the potential curriculums in the surrounding environment. In concrete, by specializing "social awareness and relationship skills" from various social and emotional ones, this study suggests an integrative program for the character education based on the theory of virtue in the Eastern philosophy. To develop such an Eastern philosophy-based integrative program for the cultivation of the social awareness and personal relationship skills, this study applies some virtue items of Eastern Ethics: for examples, 'rectification of the name(正名)' to improve skills for rational choice on the awareness and performance of social roles, 'empathy(忠恕)' to enhance the ability to share another person's feelings and emotions as if they were my own, 'reflect and seek in oneself(反求諸己)' to solve conflicts in peace and self-reflection, 'difficulty with countenance(色難)' to respond to others by understanding their situations and characters, 'select and follow good qualities of others and reform their bad qualities(擇其善者而從之, 其不善者而改之)' to make good results from various forms of personal relationship, and 'keep same respect as at first to old acquaintance(久而敬之)' to maintain good and emotional relationships. In particular, by underlining 'rectification of the name(正名)' and 'reflect and seek in oneself(反求諸己)', this study attempts to develop an alternative integrative program articulating three domains of school, family and local community.

The Janggun Pb-Zn deposit has been known one of the four largest deposits (Yeonhwa, Shinyemi, Uljin) in South Korea. The geology of this deposit consists of Precambrian Weonnam formation, Yulri group, Paleozoic Jangsan formation, Dueumri formation, Janggum limestone formation, Dongsugok formation, Jaesan formation and Mesozoic Dongwhachi formation and Chungyang granite. This Pb-Zn deposit is hydrothermal replacement deposit in Paleozoic Janggum limestone formation. The wallrock alteration that is remarkably recognized with Pb-Zn mineralization at this deposit consists of mainly rhodochrositization and dolomitization with minor of pyritization, sericitization and chloritization. Wallrock alteration is divided into the five zones (Pb-Zn orebody -> rhodochrosite zone -> dolomite zone -> dolomitic limestone zone -> limestone or dolomitic marble) from orebody to wallrock. The white mica from wallrock alteration occurs as fine or medium aggregate associated with Ca-dolomite, Ferroan ankerite, sideroplesite, rutile, apatite, arsenopyrite, pyrite, sphalerite, galena, quartz, chlorite and calcite. The structural formular of white mica from wallrock alteration is (K_0.77-0.62Na_0.03-0.00Ca_0.03-0.00Ba_0.00Sr_0.01)_0.82-0.64(Al_1.72-1.48Mg_0.48-0.20Fe_0.04-0.01Mn_0.03-0.00Ti_0.01-0.00Cr_{0.00As0.01-0.00}Co_0.03-0.00Zn_0.03-0.00Pb_0.05-0.00Ni_0.01-0.00)_2.07-1.92 (Si_3.43-3.33Al_0.67-0.57)_4.00O₁₀(OH_1.94-1.80F_0.20-0.06)_2.00. It indicated that white mica from wallrock alteration has less K, Na and Ca, and more Si than theoretical dioctahedral micas. The white micas from wallrock alteration of Janggun Pb-Zn deposit, Yeonhwa 1 Pb-Zn deposit and Baekjeon Au-Ag deposit, and limestone of Gumoonso area correspond to muscovite and phengite and white mica from wallrock alteration of Dunjeon Au-Ag deposit corresponds to muscovite. Compositional variations in white mica from wallrock alteration of these deposits and limeston of Gumoonso area are caused by mainly phengitic or Tschermark substitution mechanism (Janggun Pb-Zn deposit), mainly phengitic or Tschermark substitution and partly illitic substitution mechanism (Yeonhwa 1 Pb-Zn deposit, Dunjeon Au-Ag deposit and Baekjeon Au-Ag deposit), and mainly phengitic or Tschermark substitution and partly illitic substitution or Na⁺ <-> K⁺ substitution mechanism (Gumoonso area).

In this paper, we introduce a quadruped robot-based alarm system for monitoring the emergency situation due to falling in the elderly. Quadruped robot includes the FPGA Board(Field Programmable Gate Array) applying a red-color tracking algorithm. To detect a falling of the elderly, a sensor node is worn on chest and accelerations and angular velocities measured by the sensor node are transferred to quadruped robot, and then the emergency signal is transmitted to manager if a fall is detected. Manager controls the robot and then he judges the situation by monitoring the real-time images transmitted from the robot. If emergency situation is decided by the manager, he calls 119. When the fall detection system using only sensor nodes is used, sensitivity of 100% and specificity of 98.98% were measured. Using the combination of the fall detection system and portable camera (robot), the emergency situation was detected to 100 %.

The purpose of the present study was to evaluate the bioequivalence of two alprazolam tablets, Xanax 0.25 mg (Pharmacia Korea Pharm. Co., Ltd.) and Zyren 0.25 mg (Kwang Dong Pharm. Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). The alprazolam release from two alprazolam tablets in vitro was tested using KP VIII Apparatus II method with various dissolution media (pH 1.2, 4.0, 6.8 buffer solutions and water). The dissolution profiles of two alprazolam tablets were very similar at all dissolution media. Twenty four healthy male volunteers were divided into two groups with a randomized 2${\times}$2 cross-over study. After four tablets (1 mg alprazolam) were orally administrated, blood was taken and the concentrations of alprazolam in serum were determined using LC/MS/MS. The pharmacokinetic parameters such as $AUC_t$, $C_max$ and $T_max$were determined. Our results showed that the differences in $AUC_t$, $C_max$ and $T_max$ between two alprazolam tablets based on the Xanax were -11.65%, -4.44% and -39.31%, respectively. There were no sequence effects between two tablets in these parameter. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.25)(e.g., log(0.8386)${\sim}$log(0.9453) and log(0.8596)${\sim}$log(1.1040) for $AUC_t$, $C_max$, respectively). Thus, Zyren 0.25 mg tablet was bioequivalent to Xanax 0.25 mg tablet.

1997년 11월 대외지불 불능사태로 시작된 외환위기가 경제위기로 확산되면서 97년 4/4분기에는 2.5%에 불과하던 전북지역의 실업률은 99년 2월 8.4%로 피크를 이루었으나 그후로는 감소추세를 보이고 있다. 그렇지만 전북지역 노동시장의 전반적 고용동향을 살펴보면 실업률 통계로는 파악되지 않지만 실질적으로 준실업상태에 있는 실망노동자와 불완전취업자의 증가가 심각한 것으로 드러났다. 그리고 산업별 취업자 구조의 변화를 살펴보면 제조업과 건설업의 취업자 감소가 두드러졌으며, 농업부문이나 생계형 서비스업은 실업대란 시대에 완충역할을 해줄 것이라는 기대와는 달리 고용흡수력이 예상보다 훨씬 적은 것으로 드러났다. 취업과 실업 및 비경제활동 사이의 노동력 전이률을 살펴보면 남성과 핵심연령층에서는 취업정착률이 높지만 일단 실업자가 되면 실업으로부터의 탈출률이 낮은 것으로 드러났다. 반면에 여성의 경우에는 실망노동자(discouraged sorkers)효과로 인하여 실업률은 낮고 비경제활동으로의 이동이 크게 나타났다. 그리고 실업이나 비경활상태로부터의 (재)취업시에는 압도적으로 임시고/일고로의 취업이 많아서 98년 하반기 이후 전북지역에서 창출된 일자리가 주로 임시고/일고 위주로 이루어져 있음을 극명하게 보여준다. 한편 여성실업자의 경우 50%이상이 생계주책임자이며, 특히 여성가장 실업자의 경우에는 90%이상이 생계책임자이나 그들 대부분이 빈곤선이하에서 생활하고 있다. 그리고 전북지역에서는 전국수준에 비해서 장기실업률이 다소 높게 나타났다. 저학력층과 고령층, 생산직, 임시고일고등의 비정규직 실업자들의 구직기간이 긴 것으로 나타났다. 실업이 장기화되면 전반적으로 기간의존성효과(duration dependence effect)나 이질성효과(heterogeneity effect)로 인하여 재취업의 가능성은 더욱 떨어진다. 생산적복지(workfare)가 그 이름에 값하는 것이기 위해서는 시장경쟁력이 약한 취약계층에 대해서 직업훈련과 취업알선 및 채용장려, 공공근로 등의 제반 정책들이 가구되어야 할 것이다.

This paper implements a system that monitors human body lifting information in the event of a marine accident. The monitoring system performs ultrasonic communication through a lifting device controller that transmits underwater environment information, and LoRa communication is performed on the water to provide GPS information within 10 km to the control center or mother ship. The underwater lifting controller transmits pneumatic sensor, gyro sensor, and temperature sensor information. In an environment where the underwater conditions increase by one atmosphere of water pressure every 10m in depth, and the amount of air in the instrument decreases by half compared to land, a model of a 60kg underwater mannequin is used. Using one 38g CO2 cartridge in the lifting appliance SMB(Surface Maker Buoy), carry out a lifting appliance discharge test based on the water level rise conditions within 10 sec. Underwater communication constitutes a data transmission environment using a 2,400-bps ultrasonic sensor from a depth of 40m to 100m. The monitoring signal aims to ensure the safety and safe human structure of the salvage worker by providing water depth, water temperature, and directional angle to rescue workers on the surface of the water.
