Absorbed dose to water based protocols recommended that plane-parallel chambers be calibrated against calibrated cylindrical chambers in a high energy electron beam with $R_{50}$>7 $g/cm^2$ (E${\gtrsim}$16 MeV). However, such high-energy electron beams are not available at all radiotherapy centers. In this study, we are compared the absorbed dose to water determined according to cross-calibration method in a high energy electron beam of 16 MeV and in electron beam energies of 12 MeV below the cross-calibration quality remark. Absorbed dose were performed for PTW 30013, Wellhofer FC65G Farmer type cylindrical chamber and for PTW 34001, Wellhofer PPC40 Roos type plane-parallel chamber. The cylindrical and the plane-parallel chamber to be calibrated are compared by alternately positioning each at reference depth, $Z_{ret}=0.6R_{50}-0.1$ in water phantom. The $D_W$ of plane-parallel chamber are derived using across-calibration method at high-energy electron beams of 16, 20 MeV. Then a good agreement is obtained the $D_W$ of plane-parallel chamber in 12 MeV. The agreement between 20 MeV and 12 MeV are within 0.2% for IAEA TRS-398.

Several neutron measuring devices were tested under the neutron fields characterized with two distinct kinds of thermal and fast neutron spectrum. These neutron fields were constructed by the mixing of both thermal neutron fields and fast neutron fields. The thermal neutron field was constructed using by a graphite pile with eight AmBe neutron sources. The fast neutron field of 14 MeV was made by a DT neutron generator. In order to change the fraction of fast neutron fluence rate in each neutron fields, a neutron generator was placed in the thermal neutron field at 50 cm and 150 cm from the reference position. The polyethylene neutron collimator was used to make moderated 14 MeV neutron field. These neutron spectra were measured by using a Bonner sphere system with an LiI scintillator, and dosimetric quantities delivered to neutron surveymeters were determined from these measurement results.

Juvenile crime has recently severe problems in quality as well as great increase in quantity. Especially compared to adult crime, juvenile crime has higher recidivism rate, which leads to strong doubt about the limitations of existing treatment. This is because the correctional institutions have a bad influence on the juvenile criminal, that is not the original purpose like correction and edification, but relearning of crime. To prevent the recidivism of juvenile crime needs an active level in terms of the return as sound citizens through correction beyond a simple level of maintaining order. Correction welfare is one of the most important measures to prevent the recidivism of juvenile crime. This study examines the notion, types and trend of juvenile crime, considers the concept and functions of correction welfare, and shows the prevention of recidivism of juvenile crime in perspective of correction welfare.

Congenital tracheal stenosis can be a life-threatening disease, especially in cases involving the long-segment of the trachea. When patients are symptomatic immediately after birth or develop an accompanying complex cardiac anomaly, surgical repair can be a considerable challenge. We experienced a tracheoplasty in one early infant weighing 2.6 kg and one neonate who had ventilator dependency from long-segment congenital tracheal stenosis and congenital cardiac anomaly. One early infant, who had diffuse stenosis of distal trachea after ventricular septal defect closure, underwent resection and extended end to end anastomosis. One neonate who had diffuse stenosis of proximal trachea with tetralogy of Fallot (TOF), underwent slide tracheoplasty with total correction for TOF Postoperative chest computed tomography showed widely patent trachea. Both infants are now well without symptoms.

The treatment of choice for post-intubation tracheal stenosis is partial tracheal resection and end-to-end ana-stomosis. The surgical treatment of tracheal restenosis that results from unsuccessful repair of post-intubation tracheal stenosis is not easy. Failed reoperation results in permanent tracheostomy and loss of voice. If the first operation fails, about $4\~6$ months of period for resolution of inflammatory reaction, edema, and fibrosis is needed. The exact evaluation of the patient's status is necessary and success rate of reoperation for the appropriate candidates is over $90\%$. We report the results of treatment in two cases of tracheal restenosis that resulted from unsuccessful repair of post-intubation tracheal stenosis with review of literatures.

A review of literature revealed that damaged self-confidence of men as social agents may be the primary, if not proximal, cause of domestic violence. Accumulated damages in social confidence and self-assurance may be moderated by action repertoire acquired during childhood, and mediated by adulthood circumstances such as marital discords and the lack of social support to result in the typical cycle of violence and subsequent feeling of remorse. The present treatments for the domestically violent men in Korea seem to be ineffective to reduce the number of incidents in the society because the treatments are viewed as punishments by the men, damage their social confidence further by stigmatizing them in the community, and destroy their social resources and support systems. It was suggested in this paper to reduce the role of law enforcement and correctional administration to rehabilitate the currently violent men. At the same time, it was also suggested for the Korean court to implement the paradigm of Therapeutic Jurisprudence in handling domestic violence cases. It was argued that the court should take active roles as a healing and rehabilitating agent by cooperating with non-government community establishments such as hospitals, universities and self-help organizations. The reasons and implications of those suggestions were discussed in detail.
