Purpose : To evaluate changes and correlations of ACA, ACD and ACV by ages and refractive errors using Pentacam in Korean undergraduate students and elderly people. Methods : 52 healthy eyes(male : 27, female : 25) of undergraduate students and 38 healthy eyes of elderly people were recruited(average age : 22.52148±0.62435 years). We measured anterior chamber angle(ACA), anterior chamber depth(ACD), anterior chamber volume using Pentacam(Oculus Co.) and spherical equivalent refractive errors(SE) by subjective re(raction. 52 undergraduate students were classified into emmetropes group(-0.75-+0.750) and myopes group(> -1.000). The averages SE of emmetropes and myopes groups were -0.28333±0.32550 and -3.12162±1.51110 respectively. Results : The average ACD. ACA and ACV were 3.18906±0.20435 mm, 40.53019± 5.10831°, 193.49057±28.45213 mm3 respectively in undergraduate students group and 2.76158±0.42819 mm. 32.63947±5.84385°. 134.21053±28.94091 mm respectively in elderly group. lncreasing age was associate with reduced ACA. ACD and ACV. and there was no correlation by sex. There showed significant differences between ACD and ACA(t = - 47.64. p = 0.00). between ACO and ACV(t = -38.78. p = 0.00) and between ACV and ACA(t = 39.48. p = 0.00) l = - 50.61 p = 0.00. t = - 49.27 p = 0.00. t = 38.81 p = 0.00 respectively in undergraduate students group and t = -31.43 p = 0.00. t = -28.00 p = 0.00. t = 21.20 p = 0.00 respectively in elderl y group. Excellent correlation was found between ACD and ACV in undergraduate students group(R = 0.89). There showed significant differences in ACO and ACV(t = -2.25 p = 0.03. t = -2.24, p = 0.29 respectively), however no significant difference in ACA(t = -1.59 p = 0.12) between emmetopes group and myopes group. Conclusion : lncreasing age was associate with reduced ACA. ACO and ACV ; ACA was changed from grade 4 to grade 3 by Shaffer's classification. There showed significant differences between ACD and ACV. between ACD and ACA, between ACV and ACA Especially excellent correlation was found between ACD and ACV in undergraduate students group(R = 0.89). There showed significant differences in ACO and ACV, however no significant difference in ACA between emmetropes group and myopes group.

Jaecheol Lee. 2001. Antecedent Contained Deletion and LF Pied Piping. Studies in Modern Grammar 24, 67-90. In this paper, we prove that LF pied-piping is required for the resolution of Antecedent Contained Deletion(ACD), and that the theory-internal motives for the LF pied-piping results from economy considerations; LF convergence and the Last Resort. ACD resolution requires LF pied piping of an entire phrase out of categories that contain it. We argue that the LF pied-piping movements by Quantifier Raising and Rightward movement are triggered for the purpose of resolving the infinite regress problem in ACD configuration. Both movements are necessary to satisfy Full Interpretation at LF. We propose that QR is driven by a QU-feature, which triggers LF pied-piping of a quantificational expression in ACD configuration. The checking of QU-feature arises because the interpretively redundant QU-features on QP and its target are not allowed at the interface, which result in the violation of the principle of full interpretation. Rightward movement is driven by the Last Resort, chosen only when QR cannot occur in ACD construction.

본 연구는 호프 주산지인 강원도 횡성에서 호프 발육기 동안의 기상요소 변화에 따른 α -acid 함량 예측모형을 작성하고, α -acid 생성에 관여하는 기상요소를 구명하고자 1978년부터 1986년까지 9개년 간의 연평균 α -acid 함량과 발육단계별 기상요소를 분석 검토한 결과는 다음과 같다. 1. α -acid 함량 예측을 위하여 선택된 기상요소는 화아분화기(5월 21일~6월 20일)의 최고기온, 개화기(6월 11일~7월 10일)의 최고기온, 일조시수 그리고 강수량, 구화형성기(7월 21일~8월 20일) 최고기온이었다. 2. 개화기의 일조시수(X1 ), 개화기의 최고기온(X3 ), 개화분화기의 최고기온(X4 ), 개화기의 강수량(X5), 그리고 구화성숙기의 최고기온(X6)의 α -acid 함량 증가에 영향을 주었다. 3. α -acid 함량 예측의 중선형 회귀모형은 Y=28.369-0.003 X1 ＋1.508 X2 -1.953X3 -0.335X4 -0.003X5-0.119X6로 MSEp=0.004, Rp2 =0.9987, Rap2 =0.9949, Cp=7.00이었다.
