In this paper, we study on design of vehicle control system which is based on ${\mu}C/OS-II$, We component a electric motor drive system for simulator because the most of vehicle part use electric motor for actuator. We use the XC2287 microcontroller which is often used vehicle body controller because XC2287 guarantee high confidence and durability in vehicle industry. The electric motor control system derive PWM from general I/O port in XC2287 microcontroller. The signal is supplied at electric motor after amplifying that using driver circuit. The user control duty of PWM signal through controlling potentiometer which is connected to XC2287. through that, the user control speed of electric motor. we synchronize both input process via controlling potentiometer and PWM output process using semaphore. we verify porting of ${\mu}C/OS-II$ via experimentation. 본 논문에서는 신뢰도와 내구성이 보장되어 차량용 바디 제어기에 많이 사용되는 16bit 마이크로 컨트롤러인 XC2287에 ${\mu}C/OS-II$를 이식하고 차량의 전자제어 액츄에이터롤 많이 사용되는 모터로 시스템을 구성하여 실시간 운영체제 기반의 모터구동시스템을 구현한다. 구현한 실시간 모터구동시스템은 XC2287 마이크로 컨트롤러의 범용입출력 포트로부터 펄스폭 변조 신호를 출력하고 드라이버 회로를 통해 증폭된 신호가 DC모터에 인가된다. 사용자는 XC2287에 장착된 전위차계를 조작하여, 포트로부터 출력되는 펄스폭을 조절하고, 이를 통해 DC모터의 속도를 제어하고 출력된 신호를 모니터링 한다. 전위차계 조작에 의한 입력과정과 펄스폭 변조 신호 출력과정을 세마포어를 이용하여 동기화하는 실험을 통하여 ${\mu}C/OS-II$ 이 올바르게 이식되었는지를 검증한다.

최근 친환경적이며 고효율적인 폐동선의 재활용을 위하여 다양한 방안이 모색되고 있는 실정이다. 본 연구에서는 폐동선의 고주파 유도가열을 이용하여 폐동선의 피복제거의 실험을 수행하여 폐동선의 친환경적이며 고효율의 재활용방안을 모색하고자 다양한 공정조건하에 최적화된 방안을 도출하였다. FT-IR 분석결과, 폐동선에 코팅된 물질은 polyester임이 나타났으며, 와전류의 전산모사결과, 최적화 과정을 도출하고 이에 대하여 논의하였다. 폐동선의 피복을 효과적으로 단시간에 분리하기 위하여 폐동선을 고주파 유도코일에 수직으로 장입하고 $950^{\circ}C$이상의 온도에서 유지해야 함을 알 수 있다. Recently, the recycling with environmentally friendly method has been an issue for various fields. An effective removal method of coating layers from coated copper wires is one critical factor for recycling copper wire. We have adopted a high frequency heating routine for removing the coating layers on the coated copper wires, and attempted to find optimum conditions. The experimental results show that the copper wires should be maintained at or above $950^{\circ}C$ for rapid removal of the polyester. The simulation and experimental results are discussed with respect to the microstrucrual evolution during heating of the copper wires.

이주배경청년의 시민적 위계화와 사회적 주변화: 국적과 출생지, 젠더에 따른 차이를 중심으로

송영호 ( Song Young-ho ),최영미 ( Choi Young-mi ) 고려대학교 한국사회연구소 2021 한국사회 Vol.22 No.2

본 연구의 목적은 한국에 거주하는 이주배경청년의 시민적 위계화가 사회적 주변화에 미치는 효과를 확인하는 것이다. 이를 위하여 SSK이주배경청년사업단의 「2021년 이주배경청년 실태조사」 자료를 사용하였다. 본 자료는 학령기 이후 사회진출이 본격적으로 시작되는 만 25~34세의 이주배경청년 300명(국내출생 204명, 중도입국 96명)을 대상으로 비확률적 표집방식인 유목적표집방법(purposive sampling)으로 표본을 추출하였다. 비모수 추정 방법을 통해 도출한 주요한 결과는 다음과 같다. 우선 응답자가 한국 사회에서 계층이동이 제한되고 배제되고 있다고 느끼는 사회적 주변화 인식은 예상과 달리 부정적인 편은 아니었다. 오히려 한국 일반 청년보다 낮은 수준이었다. 하지만 시민적 계층화 유형에 따른 사회적 주변화의 수준은 외국출생자 중에서 한국 국적을 취득한 집단의 부정적 인식이 두드러졌다. 이는 한국으로 유입된 이주배경청년이 한국사회에서 이동성과 유연성, 자신의 이익을 극대화하기 위해 한국국적을 취득하였지만, 오히려 주류사회와의 경쟁 과정에서 경험하는 차별과 낙인으로 기회 공정성, 불평등 인식이 부정적 방향으로 증대한 것으로 해석할 수 있다. 다음으로 인구사회학적 특성을 통제한 상태에서 비모수적 회귀분석 결과 시민적 위계화의 위세가 낮은 집단일수록 사회적 주변화 인식이 부적(-) 방향으로 증가하였다. 즉 한국 사회에서 차등적인 시민권 부여로 객관적인 위세가 낮은 집단일수록 사회적 배제와 소외를 더욱더 느끼고, 상향 이동이 그만큼 폐쇄되었다고 인식하였다. 특히 한국국적 취득 이후 시민적 위계화의 편입 과정에서 오히려 불안감을 가장 크게 느끼고 있는 중도입국청년의 안정적인 사회진출을 위해 더욱 섬세한 정책적 고려가 필요하다. This study aims to examine the effect of civil hierarchy on the social marginalization of young adults with a migrant background. For this purpose, the Social Sciences Korea (SSK) Young Adults of Migrant Background Project Group's "2021 Survey of Young Adults of Migrant Background" was used along with a non-parametric estimation method. The major results of the analysis are as follows: First, respondents' attitudes towards social marginalization was not particularly negative, contrary to expectations, and in fact, was less negative than those of average Korean young adults. However, the pattern of social marginalization based on civil hierarchy showed a marked difference, notably that naturalized foreign-born residents (with Korean citizenship) held a distinctly negative attitude. The assumption is that these young adults of migrant background had naturalized in an effort to gain social mobility, flexibility, and a general ability to pursue their own interests; however, in the process of competing with the mainstream, the discrimination and stigmatization that they experienced may have left them with a largely negative view in the areas of equal opportunity and awareness of inequality. Lastly, the results of the non-parametric regression analysis, which controlled for demographic characteristics, showed that the lower the level in the civil hierarchy, the higher the awareness of social marginalization. In other words, those of an objectively lower social status (due to Korean society's differential treatment of residents) had a higher level of subjective awareness around social exclusion, alienation, and the reality that upward social mobility was largely closed off. Based on the results of this analysis, we argue that a more active inclusion policy―one based on "residency" rather than "nationality"―is needed to overcome current limitations in the segmented policy around "young adults with a migrant background."

The purpose of this study was to provide the basic data for the exercise rehabilitation program of the patients with shoulder pain by examining the effects of pain relief and range of motion with 8 weeks of aquatic exercise program for elderly women who have shoulder pain. The range of motion was measured by flexure and extension, abduction and adduction, horizontal flexure and horizontal extension. A subjective symptom tool for shoulder pain was used, and the severity of pain was measured using VAS(Visual Analogue Scale). Aquatic exercise program was made up with warming-up, exercise, cooling down in order to 5 minutes, 40 minutes, 5 minutes and carried out during 8 weeks for 4 times a week (Mon, Tue, Thu, Fri). The strength of exercise for 1-4 weeks was 13 (a little hard) - 15 (hard), and that of 5-8 weeks was 16 (hard) - 18 (very hard). The data obtained in this experiment was processed by ‘Windows SPSS(version 20.0)’ statistical computer program, and paired sample t-test (Paired t-test) was performed in order to clarify the difference between pre-test and post-test in 8 weeks aquatic exercise program. The measurements of all the items were presented as descriptive statistics (mean ±standard error), and the significant probability of all the statistics was set to p<.05. The conclusions of this study are so follows: First, there were very significant differences in patients such as the increase of flexure and extension abduction and adduction horizontal flexure and extension in post-test than pretest and before having aquatic exercise (p<.001). Second, the patients’ subjective symptom for shoulder pain scores were decreased in the post-test than the pretest with very significant differences (p<.001). Third the patients’ awareness of pain were decreased in the post-test than the pretest with highly statistically significant differences (p<.001).

송영호(Young-Ho Song),이태양(Tae-Yang Lee),이종덕(Jong-Deok Lee),문찬우(Chan-Woo Moon),정구민(Gu-Min Jeong),안현식(Hyun-Sik Ahn) 제어로봇시스템학회 2010 제어·로봇·시스템학회 논문지 Vol.16 No.6

In this paper, we present a transformation method of source code from a POSIX (Portable Operating System Interface) based source code into an OSEK/VDX (Offene Systeme und deren Schnittstellen fur die Elektronik in Kraftfahrzeugen/Vehicle Distributed eXecutive) source code. As the electronic parts of automobile systems increase, the use of embedded software in automobile systems is also growing. Accordingly, many electronic systems are designed in automobile system with OSEK/VDX. Otherwise, one of the major problems of embedded software would be portability to other OS’s. To enhance the portability and interoperability of embedded software, we propose a source code transformation method from POSIX to OSEK/VDX based on API (Application Programming Interface) translation method. Considering the characteristics of the OSEK/VDX which uses OIL (OSEK/VDX Implementation Language) standard, transformation process is performed with source code transformation and OIL code generation. For the validity of the proposed method, the transformation experiment is given using Micro-C OS II and OSEK/VDX with XC167CI micro-controller.

This paper aims to find Symbol-System of Shin, Seok-Jeong's poetry focusing main images and words of his poetry. Shin, Seok-Jeong was one of pioneering poet. he developed the proper function of lyric poetry based on unusual utopia consciousness in Korean modem poetry. In addition, he was individual poet reformed participation poet before and after the liberation. His poetry during fifty years had formed its own context throughout literary meaning and participation poet. Shin, Seok-Jeong's poetry during fifty years of the Japanese colonial rule and division period was based on pellucid the country lyric and negative perception of reality represented 'Night'. His poetry seeks mostly pure love of human, life, peace. His poetry is rooted in Korean traditional lyric to commune with 天, 地, 人. Especially, Shin, Seok-Jeong's poetry as utopia recovery poetry during paradise lost period and the Japanese colonial rule had unique meaning and individual position. Paradise lost found in Shin, Seok-Jeong's poetry were effective poetic symbol for getting over deprivation of the time and crisis killed sovereignty and right to live. And Shin, Seok-Jeong poet suggested what is a desirable way of poet and poetry since 1930. And then, he kept his distance from republic of letters of division period and radical public literature. He committed himself to poet's duty of reality participation, at the same time he was flowered pure lyric poetry. His poetry should gain attention because it combined classical scholarship with pure lyricism. So republic of letters begin in earnest about his poetry.
