In the previous review, the physical aspect of heavy particles, with a focus on the carbon beam was introduced. Particle beam therapy has many potential advantages for cancer treatment without increasing severe side effects in normal tissue, these kinds of radiation have different biologic characteristics and have advantages over using conventional photon beam radiation during treatment. The relative biological effectiveness (RBE) is used for many biological, clinical endpoints among different radiation types and is the only convenient way to transfer the clinical experience in radiotherapy with photons to another type of radiation therapy. However, the RBE varies dependent on the energy of the beam, the fractionation, cell types, oxygenation status, and the biological endpoint studied. Thus this review describes the concerns about RBE related to particle beam to increase interests of the Korean radiation oncologists' society.

PURPOSE: This study was performed to investigate the differences in career choice motives and moral reasoning ability between students in baccalaureate and graduate-entry medical programs. METHODS: Forty-five students from a baccalaureate program and thirty-eight students from a graduate-entry program participated in this study. The students were required to fill out both the Career Choice Motivation Inventory and Defining Issues Test(DIT). The Career Choice Motivation Inventory is a 20-item questionnaire, which investigates five dimensions: effect of others, job security, interest in science, service and working with people, and working condition. Independent t-test was performed to compare the two groups. Pearson correlation coefficients were calculated to investigate the relationship among variables. RESULTS: There were significant differences in career choice motivations between the two groups. Students in the graduate-entry program were more likely to be motivated by scientific interest and opportunities to care for people. Status and job security were stronger factors in the baccalaureate students. For the students in this program, there were positive associations among their motives- interest in medical science, serving people, and working condition. There was no significant difference in moral reasoning ability between the two groups. CONCLUSION: Students in the graduate-entry medical program seem to have more professional and altruistic motivations for entering medicine. Although there is nostatistical significance, graduate students have numerically higher moral reasoning abilities compared to their counterparts. These results validate that a graduate-entry program provides an important alternative for student selection.

A clinical study of 147 clavicle fracture patients (one patient had bilateral fractures) who were admitted and treated by the Department of orthopedic surgery of Wonju Christian Hospital, Wonju Medical College, Yon Sei University. The period covered was from September 1974 to August 1981, a total of seven years. The study focused on three fertors in relation to the pain and limitation of motion and these causes were comminution of fracture, shortening of the clavicle length and external deformity. The results were as followings; l. Of the 148 cases, 125 were male and 22 female (one with bilateral fractures). The majority were between 31 and 40 years of age. 2. The mid 1/3 fracture was most common and both sides showed no difference in incidence(left ; 73 cases, right; 75 cases). 3. The mean follow up ranged from 4 months to H3 months with a mean 49.5 months. 4. The complications resulting from comminution, shortening of clavicle length and malunion were shoulder joint pain-16 cases (10.8%), limitation of motion-17 cases(11.5%) and external deformity-18 cases(12.9%). 5. Using a rating scale of excellent(no apparent factors), good( one factor), fair(two factors), poor(more than three factors) the results showed, 106 excellent, 31 good, 9 fair and 2 poor. 6. On a percentage scale, the pain showed difference of 9 times with initial comminution, 7 times with shortening of clavicle length and 7 times with deformity. 8. On a percentage scale, the limitation of motion of shoulder joint showed difference of 6 times with initial comminution, 6 times with shortening of clavicle length and 17 times with deformity.
