현실에서 기업의 성장이 멈추는 성장통이 자주 발생하지만, 선행 연구에서는 성장요인만을 분석하고 있는 한계를 지닌다. 성장요인의 반대가 실패요인 또는 정체요인이라는 것을 의미하지는 않는다. 이에 본 연구에서는 기업의 지속가능한 성장을 저해하는 성장통이 발생하는 시점, 이유를 살펴보고, 성장통 극복 전략을 실증적으로 살펴보고자 한다. 각각 10년 이상 성장경로가 추적 가능한 5,045개의 한국 제조기업 데이터(1985-2014)를 사용하여 각 기업별로 성장통이 발생하는지를 살펴보고 그것들의 공통된 특징을 파악하였다. 분석결과 4,521개 기업(89.6%)이 성장통을 경험하였으며, 이들 중 25.5%만이 성장통 이전의 규모로 회복하였다. 고성장 기간 때 R&D투자, 부채를 감소하였을 때 다음 해에 성장통이 초래 될 확률이 높았다. 즉, 기업은 안정화를 추구하고 새로운 성장동력 확보에는 미흡하였다. 기업이 성장통에 극복하기 위해서는 적극적인 R&D투자와 물적투자를 펼침과 동시에 부채를 감소시키는 안정화 전략이 동시에 요구되었다. 내부 자원이 부족한 상황에서 내부 자원에 의존하는 투자활동을 펼쳐야 한다는 점에서 성장통이 발생하였을때 이를 극복하는 것이 그만큼 어렵다는 것을 시사한다.

A class action is one branch of civil procedure. But it has a series of features, and one of them is to lead positively litigation. The judicial active control of class action appear upon judicial control of settlement and litigation. I will specially study on the judicial scrutinty of proposed settlement and settlement before certification decision. Also judicial control of pretrial litigation will be studied.

There are two types of counterclaim in american civil procedure, the one is compulsory counterclaim and the other is permissive counterclaim. The latter form of counterclaim can be seen in Korea, but the former form is not familiar. Counterclaim is compulsory if it is met one of the four tests, ①same issues of fact and law, ②res judicata as test, ③same evidence as test, and ④logical relation test. Compulsory counterclaim contributes to procedural economy and fairness, and so on. But if the defendant does not assert the compulsory counterclaim in former action, the claim cannot be asserted in later action by claim preclusion rule. Claim preclusion rule is different between Korea and U.S.A., so the principle of compulsory counterclaim cannot be permissive in Korea. But it would be also useful to us to analyse the rule.

Eu red phosphor was prepared by microwave synthesis. The crystal phase, particle morphology, and luminescent properties were characterized by XRD, SEM, and spectrofluorometer, respectively. The prepared :Eu particles had good crystallinity and strong red emission under ultravioletet excitation. The crystallite size increased with calcination temperature and satuarated at . The primary particle size initially formed was varied from 30 to 450 nm with microwave-irradiation (MI) time. It was found that the emission intensity of :Eu phosphor strongly depends on the MI time. In terms of the emission intensity, it was recommended that the MI time should be less than 15 min. The emission intensity of :Eu phosphor prepared by microwave syntehsis strongly depended on the crystallite size of which an optimal size range was 50-60 nm

A bidirectional dc–dc converter is used in battery energy storage systems owing to the growing requirements of a charging and discharging mode of battery. The magnetic coupling of output or input inductors in parallel-connected multi modules of a bidirectional dc–dc converter is often utilized to reduce the peak-to-peak ripple size of the inductor current. This study proposes a novel design guideline to achieve minimal ripple size of the inductor current under bidirectional power flow. The newly proposed design guideline of optimized coupling factor is applicable to the buck and boost operation modes of a bidirectional dc–dc converter. Therefore, the coupling factor value of the coupled inductor does not have to be optimized separately for buck and boost operation modes. This new observation is explained using the theoretical model of coupled inductor and confirmed through simulation and experimental test.

폐 폴리스티렌과 모터 오일의 혼합물로부터 마이크로웨이브 열분해를 이용하여 유용한 고분자 원료물질의 회수를 위한 연구를 수행하였다. 마이크로웨이브 반응기로 quartz tube를 사용하였으며 마이크로웨이브 흡수체로 실리콘 카바이드를 사용하였다. 공정 변수로 마이크로웨이브 입력 파워를 180에서 250 W까지 변화시켰으며, 마이크로웨이브 조사시간을 30분에서 1시간까지 변화시키며 실험하였다. 열분해를 통하여 얻어진 생성물을 GC/MS를 사용하여 분석한 결과 스티렌, 메틸 스티렌, 톨루엔, 그리고 에틸벤젠이 4개의 주요 회수 성분이었으며, 이 중 폴리스티렌으로부터 스티렌의 회수율은 약 50% 이었다. 열분해에 마이크로웨이브를 사용함으로써 일반 열분해 보다 훨씬 낮은 온도에서 열분해가 이루어졌다. A novel microwave-induced pyrolysis was used for the recovery of valuable products from waste polystyrene in motor oil. Quartz tube was introduced as microwave reactor and silicon carbide was used as the microwave absorbent. In the experiments, different pyrolysis conditions were applied, such as time range from 30 minutes to 1 hour and microwave input power range from 180 to 250W. The distillate products from pyrolysis were analyzed with GC/MS. Styrene, 1-methyl styrene, toluene, ethyl benzene were the four main products. Styrene recovery rate from polystyrene was around 50%. Temperature for the complete pyrolysis using microwave was around $300^{\circ}C$ which is much lower than that of conventional thermal pyrolysis.

The aims of this study are to evaluate the measurement capability of the electromagnetic power and to understand the current state of standard maintanance of the eight participants among the thirteen national calibration and test organizations. The calibration factors were measured at six test frequencies, 50, 100, 500, 1000, 5000, 10000 MHz by organizations and KRISS on the basis of round robin test. The results were analyzed by calculating the standard deviation of the measured values from the standard values. The analysis shows good agreement within 1.0% for all participants at the measurement frequencies. Therefore, the measurement capability of all participants is good in the frequency range of 50 MHz to 10 GHz. For the four participants which specified standard deviations of repeated measurements in their reporst, the total uncertainties is less than 1.9% at the measurement frequencies.
