The purpose of this study was to compare the effectiveness of programmed instruction versus lecture and discussion method on the knowledge of basic reference sources among undergraduate library and information science students. The hypotheses of the study were: 1. Programmed instruction will be more effective than the lecture/discussion method with regard to academic achievement. 2. There will be a significant difference in learning time between the experimental and the control groups. Seventy-eight library and information science students were participated m the study from the two universities in Chungchong Province. A programmed instruction manual, including 4-types of reference sources-dictionary, encyclopaedia, bibliography, indexes and abstracts, 40-item multiple choice post-test, and a questionnaire for the students' attitude toward programmed instruction were developed specifically for this research. The post-test only control-group design was selected for this experimental study. Students were given instruction on the specific reference titles in dictionary, encyclopedia, bibliography, indexes and abstracts. The control group was instructed by the lecture and discussion method while the experimental group completed a programmed instruction manual by themselves. Both the control and the experimental group were tested right after the instruction of 4-types of reference sources. In addition, a questionnaire asking students' attitude toward programmed instruction was administered to the experimental group. The findings from this study are summarized as follows: 1. The results showed that there were no significant difference in the mean of the post test score between the two groups. Therefore, programmed instruction is viable as an alternative method of instruction in the teaching of reference sources. 2. There was a significant difference in the mean of time spending for the leaning of bibliography, indexes and abstracts between the two groups. Accordingly, programmed instruction proved to be more efficient than the conventional lecture/discussion method in terms of learning time. 3. Students showed positive response to programmed instruction and evaluated it very interesting and challenging. In conclusion, the programmed instruction method was just as effective as the lecture/discussion method in the teaching of reference sources. And students' attitude toward the programmed instruction was favorable enough to secure a continued use of this method for the teaching of reference sources.

Programmed instruction has recent]y advanced greatly thinks to extensive world-wide research. Many countries including the United States have increasingly applied the method not only to education, but to such fields as the armed forces and business circles, too. The author has paid great attention to the programmed instruction of other countries and its application to nursing education in Korea. The author studied the matter mainly through descriptive research and has come conclusions as follows: 1) The nursing education in Korea is confronted with the great challenge of how to provide more effective learning for increased learners. Programmed instruction could meet the challenge partially and improve the general quality of student nurse. 2) Programmed instruction could reduce the required study hours by one-third so that the current excessive school credit system could be rearranged properly. 3) Programmed instruction could provide teachers and professors with more free hours to spend with students and give them advice on a kind of tutorial basis. This could bridge the gaps among the students so the improvement of the average quality of learners could be attained. There are, however, many unsolved problems in applying the programmed instruction to nursing education in Korea. Further research should be made to work out a more effective programmed instruction fit to the reality of Korea's nursing education.

Microcontrollers (MCUs) for endpoint smart sensor devices of internet-of-thing (IoT) are being implemented as system-on-chip (SoC) with on-chip instruction flash memory, in which user firmware is embedded. MCUs directly fetch binary code-based instructions through bit-line sense amplifier (S/A) integrated with on-chip flash memory. The S/A compares bit cell current with reference current to identify which data are programmed. The S/A in reading '0' (erased) cell data consumes a large sink current, which is greater than off-current for '1' (programmed) cell data. The main motivation of our approach is to reduce the number of accesses of erased cells by binary code level transformation. This paper proposes a built-in write/read path architecture using binary code inversion method based on hot-spot region detection of instruction code access to reduce sensing current in S/A. From the profiling result of instruction access patterns, hot-spot region of an original compiled binary code is conditionally inverted with the proposed bit-inversion techniques. The de-inversion hardware only consumes small logic current instead of analog sink current in S/A and it is integrated with the conventional S/A to restore original binary instructions. The proposed techniques are applied to the fully-custom designed MCU with ARM Cortex-M0$^{TM}$ using 0.18um Magnachip Flash-embedded CMOS process and the benefits in terms of power consumption reduction are evaluated for Dhrystone$^{TM}$ benchmark. The profiling environment of instruction code executions is implemented by extending commercial ARM KEIL$^{TM}$ MDK (MCU Development Kit) with our custom-designed access analyzer.

There hasn't been a study searching for various methods of instruction and orientation in the use of a college library. By searching through the western literature in this field from 1961, I was amazed by the vast literature and enormous study done on it. I tried to introduce the most important articles in this field which can help mold our methods of library instruction. There has been quite a few cries for the use of new methods, of newer media, for increased number of students. Promising future lies in the area of programmed instruction and audiovisual aids to teaching, which should be developed into course-related library instruction.

Condominium management ask for planning ability and special knowledge in order to solve the troubles of a condominium. But all the HOA has not ability or knowledge of condominium management, so administration support to condominium management came to be given to HOA. In this study, we divided the administration policies on condominium management as follows; (1) instruction about an advertisement and a contract (2) instruction about management (3) instruction about maintenance (4) instruction by the local government (5) legislation about condominium management. Most of the condominium management policy has been programmed by government, such as legal amendments and advises by administrative inspection. But these condominium management policies have limitations to support HOA, so it is need to correspond to local government. In advanced local governments, administrative policies were materialized by the report of a housing related council. HOA: Home Owners Association

PLC와 같은 특수 목적 제어기나 모션 제어기 등을 프로그램하기 위해 제공되는 제어 언어의 표준은 IEC61131-3이다. 이 표준 언어의 하나인 IL(Instruction List)은 어셈블리 수준의 언어이지만 고수준 언어의 특징들도 가지고 있다. 본 논문에서는 IL의 정형적인 의미구조를 실행적 의미구조를 이용하여 정의한다. 기존의 IL 의미구조들은 함수와 함수블록을 포함하지 않는 기본 프로그램만을 대상으로 하기 때문에 실용적이지 못하다. 우리는 함수와 함수블록을 포함하는 IL 의미구조를 정의하였다.

This paper presents the design of high speed processor for a sequence logic control using field programmable gate array(FPGA). The sequence logic controller is widely used for automating a variety of industrial plants. The FPGA designed by VHDL consists of program and data memory interface block, input and output block, instruction fetch and decoder block, register and ALU block, program counter block, debug control block respectively. Dedicated clock inputs in the FPGA were used for high speed execution, and also the program memory was separated from the data memory for high speed execution of the sequence instructions at 40 MHz clock. Therefore it was possible that sequence instructions could be operated at the same time during the instruction fetch cycle. In order to reduce the instruction decoding time and the interface time of the data memory interface, an instruction code size was implemented by 16 bits or 32 bits respectively. And the real time debug operation was implemented for easy debugging the designed processor. This FPGA was synthesized by pASIC 2 SpDE and Synplify-Lite synthesis tool of Quick Logic company. The final simulation for worst cases was successfully performed under a Verilog HDL simulation environment. And the FPGA programmed for an 84 pin PLCC package was applied to sequence control system with inputs and outputs of 256 points. The designed processor for the sequence logic was compared with the control system using the DSP(TM320C32-40MHz) and conventional PLC system. The designed processor for the sequence logic showed good performance.

Condominium management ask for planning ability and special knowledge in order to solve the troubles of a condominium. But not all HOA have that ability or knowledge, so administration support to condominium management came to be given to HOA. In this study, we divided the administration policies on condominium management as follows;$\circled1$instruction about an advertisement and a contract$\circled2$instruction about management$\circled3$instruction about maintenance $\circled4$ instruction by the local government $\circled5$ legislation about condominium management. The condominium management policy has been almost programmed by the state, such as legal amendments to laws and advises by administrative inspection. But these condominium management policies by the state have limitations to support HOA appropriately, so correspondence of the local government is called for, On the other hand, in the local governments, grasp basic contents for execution to the condominium management policy, an information of offering and consultation has been started. And system that suits the situation and the characteristic of each district was provided. However it could not say that we grasp the tendency of the condominium management policies wholly of the local governments, so it remains as a subject because it is not long since condominium management policies of the local government started, and we picked up only metropolis in this study. In the future, it is necessary to search on the consciousness of a resident and the HOA about the condominium management policy, and make out the data which can be reflected in policy deployment in the local governments from now on. ＊ HOA ‥‥ Home Owners Association

This paper presents the design of high speed bit and word processor for sequence logic control using a FPGA. This FPGA is able to execute sequence instruction during program fetch cycle, because the program memory was separated from the data memory for high speed execution at 40MHz clock. Also this processor has 274 instructions set with a 32bit fixed width, so instruction decoding time and data memory interface time was reduced. This FPGA was synthesized by V600EHQ240 and Foundation tool of Xilinx company. The final simulation was successfully performed under Foundation tool simulation environment. And the FPGA programmed by VHDL for a 240 pin HQFP package. Finally the benchmark was performed to prove that the designed for bit and word processor has better performance than Q4A of Mitsubishi for the sequence logic control.
