The Joseon Dynasty suffered a great loss from the Japan invasion of Korea in 1592. At that time so many precious books were plundered by Japanese Army. And that plundered books, now in Japan, include a lot of complete titles of the books were given by the Kings - the Naesabon (內賜本) - of the early Joseon Dynasty period. If we could find out the quantities and the contents of them, it could be helpful for studying the same books remained incompletely now in Korea. In this respect, understanding current situation of the Naesabon(內賜本) is an important subject of the Korean bibliographic and historical studies. The purpose of this study is finding out the current situation of the Naesabon(內賜本) now in Japan, especially published in 16th century.

The Naesabones(內賜本) are the books awarded to the organizations and the individuals by the Kings of Joseon(朝鮮) Dynasty. The organizations include the history archives[史庫], the government offices[官廳], the private academies[書院] and the county public schools[鄕校]. The individuals include the royal family members and the members of the cabinet. In Joseon Dynasty, the books were distributed to the government offices, the members of the cabinet, and the people who participated in printing that book. Also after the official ceremonies, the books were given as the rewards. The purpose of this study is to examine the bibliographical features of the naesabones - especially awarded to the individuals - now in Kyujanggak.

This Study on three different methods which are Von Graefe test, Maddox Rod test and Howell card test of measuring far and near lateral phoria investigated. It reviewed that 420 subjects aged from 15 to 35 years old. The result were as follows; 1. Using Von Graefe lateral phoria measurement, they were measured 6% for orthophoria, 62% for exophoria, 32% for esophoria at far distance. 2. Using Von Graefe lateral phoria measurement, they were measured 2% for orthophoria, 74% for exophoria, 24% for esophoria at near distance. 3. Using Maddox Rod lateral phoria measurement, they 59% for exophoria, 37% for esophoria at far distance. 4. Using Maddox Rod lateral phoria measurement, they 67% for exophoria, 30% for esophoria at near distance. 5. Using Howell card lateral phoria measurement, they 60% for exophoria, 32% for esophoria at far distance. 6. Using Howell card lateral phoria measurement, they 69% for exophoria, 27% for esophoria at near distance.

Purpose: To investigate the near horizontal heterophoria of the college students in their twenties on north Kyonggi Province. Methods: The all subjects had not experienced any ocular surgery and have no disease and their mean age is 22.9. As 122 subjects, they are 50 emmetropes and 72 ametropes. The ametropes are all myopia. After distance visual acuity correction with subjective and objective refraction test, evaluated their horizontal heterophoria with red maddox rod. Results: In maddox rod test, the subjects consist of orthophoria 4.9%, esophoria 9.8% and exophoria 85.3%. In the emmetropes orthophoria is 8%, esophoria is also 8% and exophoria is 84%. In the ametropes orthophoria is 2.8%, esophoria is 11.1% and exophoria is 86.1%. The mean size of horizontal heterophoria is esophoria 3.59PD (prism diopter), exophoria 7.04PD and in the emmetropes esophoria is 3.25PD, exophoria is 6.60PD. In the ametropes esophoria is 3.75PD and exophoria is 7.34PD. Conclusions: In the emmetropoes the orthophoria is more than in the ametropes and the esophoria and exophoria is more in the ametropes. But the differences between the heterophoria and emmetropia or ametropia were not significant (p>0.05). The mean size of heterophoria is higher in the ametropes than in the emmetropoes. The distribution range of heterophoria is wider in the male subjects than the female subjects.

117 undergraduate ophthalmic optics students volunteered to participate in this study. They ranged in age from 19 to 26 years. Subject, had best corrected visual acuity of at least 1.0 in both eyes, no strabismus, no amblyopia, and no history of ocular surgery. 37 subjects are esphoria and 25 subjects are $3{\Delta}$ and less, and the rest of 12 subjects show more $4{\Delta}$. Average phoria amount is $2.96{\Delta}$ at far distance and $1.08{\Delta}$ at near distance, respectively. The variation of phoria amount in far and near distance, unchanging subjects are 3, 8 subjects are increase esophoria amount, and 26 subjects are phoria amount decreasing or appear exophoria. The reason of esophoria amount is decreasing in near distance, and the results are convergence burden decreases. At positive relative convergence, the expected value in far distance, blurred point is 7, break point is 16, and recovery point is 12. And negative relative convergence, break point is 7 and recovery point is 13, respectively. Moreover, at positive relative convergence, the expected value in near distance is blurred point is 8, break point is 7 and recovery point is 22. And negative relative convergence, blurred point is 2, break point is 8 and recovery point is 12, respectively.

The purpose of this study was to compare the compression force and thickness of the compressed breast between mediolateral oblique and craniocaudal mammography. This population consisted of 204 paired mediolateral oblique and craniocaudal mammography obtained on one mammographic unit by certified mammography technologists during 2 month period. The women examined were $30{\sim}59$ years old with breast implants, the patients were classified into 3 groups according to age, $30{\sim}39$, $40{\sim}49$, and $50{\sim}59$, prior breast cancer, mastectomy or breast deformity were excluded. The digital readout of compressed breast compression force and thickness was recorded. Mammographic positioning was assessed using standard criteria. The mean compression force of the compressed breast on the craniocaudal projection was less than the mean compression force on the mediolateral projection(14 versus 13.88 daN, p<0.05). The mean thickness of the compressed breast for mediolateral projection was 41.46 mm and that for the craniocaudal projection was 39.50 mm(p<0.05). The compressed breast is higher or thicker on mediolateral oblique than on craniocaudal mammography.

Purpose: To study the relationship of N.P.C, heterophoria and near convergence and divergence by amount of the refractive error. Methods: All subjects have no ocular disease and their mean age is 22.7. All 39 subjects examined about refractive error, near point of convergence (NPC), heterophoria, near convergence and divergence. Results: Classified by low refractive state, middle refractive state, and high refractive state compared with the expected value of Morgan. NPC had been measured within low and middle refractive state eight all the 8cm. However, high refractive state measured 9.64 cm. Low and middle refractive state for the classification by near phoria. Near esophoria groups was smallest by near divergence and exophoria groups was smallest by near convergence. Conclusions: Near convergence were largest with esophoria while near divergence were largest with exophoria.
