Network anomaly detection is a technology that collects information about flows on a network and detects malicious attacks occurring in a network in real time. In-band Network Telemetry (INT) technology provides more detailed information in real time, that is not provided by existing networks, such as hop latency and queue occupancy. In this paper, we propose the method to implement an anomaly detection system with higher performance by using INT as an input feature of machine learning and verify it through experiments.

742 cases of thyroid diseases treated at Radio-isotope Clinic, Seoul National University Hospital since October 1965 through July 1968 were analyzed. The patients were classified according to eye findings, as to Infiltrative, Non-infiltrative and No ophthalmopathy. Correlations between ophthalmological findings and symptoms, BMR values and $^{131}I$ uptake rate as well as response to medical treatment were carefully reviewed. Results obtained were as follows: 1. Among goitrous patients 44.5% with infiltrative ophthalmopathy, 24.1% with non-infiltrative ophthalmopathy totaling 68.6% of patients with one or more eye findings were found. Exophthalmos (44%) and visual disturbances (44%) comprised the highest incidence among eye signs. Most frequent eye symptoms were lid swelling (17.1%). 2. Female patients were predominant(91%). 3. Of cases with hyperthyroidism, after treatment with antithyroid drugs and radio-iodine therapy, general symptoms were improved in over 74%, whereas ophthalmopathy was not changed and in some cases the eye signs were aggravated. This tendency was more apparent in infiltrative ophthalmopathy. 4. Significant correlations between exophthalmos, BMR values and $^{131}I$ uptake rate were found. Among the patients of same degree of exophthalmos, BMR values and $^{131}I$ uptake rate showed the highest in non-infiltrative ophthalmopathy, moderate in infiltrative ophthalmopathy and the lowest in no ophthalmopathy.

As we know, Incoterms are reflecting only the greatest common measure of practice in int'l trade. Therefore we can think them as the commercial practice most widely used in trade. They contain a number of detail under converse mirror image terms because they connect each other like a thread as to all oversea's commercial transactions between importing buyers and exporting sellers. Therefore they afford convenience to exporters and importers in the world because they tell the parties what to do as to transfer of risk and costs, responsibilities in connection with delivery of the goods. Nonetheless, since Incoterms 1936, they have been periodically revising in order to represent contemporary commercial practice. Therefore, according to change of Int'l trade environment, ICC plans to modify to the 2000 Incoterms. I hope to contribute to revising works by reference of above mentioned revision, that to say, aspects of provision, reflection of prevailing most commonly used, promotion of status as uniform rules, provision of convenience of int'l buyers and sellers. harmony with existing int'l instruments, presentation of criteria in variation of Incoterms.

Let ${X_i}$ be a process with stationary and independent increments whose log characteristic function is expressed as $ibut-2^{-1}\sigma^2u^2t+t\int_{{0 }^c}{(exp(iux)-1-iux(i+x^2)^{-1})dv(x)}$. Our main result is taht $x^2(\int_{\y\>x}{dv(y)})/(\int_{$\mid$y$\mid$\leqx}{y^2dv(y)+\sigma^2}) \to 1$ as $x \to 0 (resp. x \to \infty)$ is necessary, and sufficient for ${X-i}$ to have ${A_t}$ and ${B_t}$ such that $(X_t-A_t)/B_t \to^D n(0,1)$ as $t \to 0 (resp. t \to \infty)$.

$^{99m}Tc-Sulfur$ Colloid is concentrated in Kupffer cells of the liver, whereas the new biliary agents such as $^{99m}Tc-HIDA$ are processed by hepatic parenchymal cells. The distant metastatic lesiors in skull and lung of the primary hepatocellular carcinoma in 38-year old Korean male were detected with $^{99m}Tc-HIDA$ scintigraphy. The chest PA, skull bone X-ray and radionuclide scintigraphic studies are illustrated. This observation suggests that $^{99m}Tc-HIDA$ scintigraphy is useful for detection of distant metastases of primary hepatocellular carcinoma.

This study was conducted to determine the effect of the adrenal function on the reproductive organs in immature rats treated with PMS. Two hundred and ten female rats (Wistar-Imamichi albino rats) of 21 days old (body weight : $58.7{\pm}3.53g$) were disposed in the intact rat group (Int.-) and adrenalectomized rat group (Adx.-) and then each group was devided into 3 subgroups, such as control (-Cont.), PMS treated (-PMS) was administered subcutaneously with 25 IU PMS, and and PMS cortisol treated groups (-PMS+Corti.) with 25 IU PMS and $30.0{\mu}g$ cortisol on 5 th day (aged 26 days old) after adrenalectomy, while the control groups with physiological salt solution by the same way. The reprodutive organs were observed at 48, 54, 60, 66, 72, 78 and 84 hours after hormone treatments. The results obtained were as follows ; 1. The measurments of time average ovary weight in all treated groups were increased with the elapse of time after treatment, and the difference among the treatments was significant (p<0.01) in the all observation time. But the difference of those was not recognized in Int.-Cont. and Adx.-Cont. groups. In the multiple range test. ovary weight of adrenalectomized rat groups (Adx.-PMS and Adx.-PMS+Corti. groups) was significantly (p<0.05) lighter than those of intact rat groups (Int.-PMS and Int.-PMS+Corti. groups), and the effect of cortisol administration was not reconized. 2. The difference of uterus weight was significantly reconized (p<0.01) in all observation time. The weight in Int.-PMS and Int.-PMS+Corti. groups was heavier until 66 hours after treatment, but the values in the adrenalectomized Adx.-PMS and Adx.-PMS+Corti. groups were heavier after 72 hours. The multiple range test showed that the significant difference was not found between Int.-PMS and Int.-PMS+Corti. groups, and Adx.-PMS and Adx.-PMS+Corti. groups. 3. The adrenal weight was not significantly different among the compared groups.

The purpose of this experiment was to investigate the effects of adrenalectomy and PMSG treatment on reproductive organs and serum steroid hormone level in immature female rats. The animals used in this experiment were 25 days old female rats weighing a, pp.oximately 70g. They were randomly divided into two groups of intact rat group (Int-) and adrenalectomized rat group (Adx-) and each group were subdivided into two groups of Non-PMSG (-Cont) and PMSG treated (-PMSG) group. The rat of PMSG-treated group (-PMSG) was administered subcutaneously with 25 IU PMSG on first day (9 a.m.) after adrenalectomy. The adrenalectomized rat groups were su, pp.ied with saline solution through the experiment period. The rate of ovulation and vaginal opening and reproductive organ weights were observed at 8, 32, 56, 80 and 104 hours after PMSG treatment. At the same time, the serum level of estradiol-17${\beta}$ and progesterone were measured by the radioimmunoassay. The results obtained were as follows: 1. Ovulation was shown at 56 hours after treatment in Int-PMSG group and Adx-PMSG group and Adx-PMSG group. The rate of ovulation was very low in PMSG-treated groups, but it was increased in 80 to 90% at 104 hours after treatment. However, there was no ovulation in Int-Cont group and Adx-Cont group. 2. Vaginal opening was shown at 56 hours after treatment in Int-PMSG group and Adx-PMSG group and a, pp.ared in 80% at 104 hours after treatment. The rate of vaginal opening in PMSG-treated groups was very low, but Int-Cont group and Adx-Cont group had no vaginal opening. 3. The weight of ovary and uterus in two PMSG-treated groups were increased with the elapse of time after treatment and were significantly heavy in all observation time, but changes in Int-Cont group and Adx-Cont group were not recognized. The weights of ovaries and utera in Adx-Cont group were increased with the elapse of time. 4. The level of serum estradiol-17${\beta}$ was remarkably increased in PMSG-treated groups (Int-PMSG and Adx-PMSG groups) compared with Int-Cont and Adx-Cont group, and significant difference was recognized between Non-PMSG group and PMSG-treated group in the experimental period. Especially, the highest levels of Int-PMSG groups and Adx-PMSG groups were shown at 80 and 56 hours after treatment and after ward estradiol-17${\beta}$ levels of PMSG-treated groups were decreased. However, changes of the levels did not a, pp.ared in Non-PMSG groups at 104 hours after treatment. 5. The level of serum progesterone in PMSG-treated groups was significantly increased between 80 and 104 hours after treatment. With the elapse of time, the level was increased in all observed groups except for Int-Cont and Adx-Conx group. And the order from the highest level at 104 hours after treatment was Int-PMSG, Adx-PMSG, Int-Cont and Adx-Cont group.

An analysis of emotional English utterances with 7 emotions (calm, happy, sad, angry, fearful, disgust, surprised) was conducted using the measurement of prosodic distance between 672 emotional and 48 neutral utterances. Applying the technique proposed in the automatic evaluation model of English pronunciation to the present study on emotional utterances, Euclidean distance measurement of 3 prosodic elements such as F0, intensity and duration extracted from emotional and neutral utterances was utilized. This paper, furthermore, extended the analytical methods to include Euclidean distance normalization, z-score and z-score normalization resulting in 4 groups of measurement schemes (sqrF0, sqrINT, sqrDUR; norsqrF0, norsqrINT, norsqrDUR; sqrzF0, sqrzINT, sqrzDUR; norsqrzF0, norsqrzINT, norsqrzDUR). All of the results from perceptual analysis and acoustical analysis of emotional utteances consistently indicated the greater effectiveness of norsqrF0, norsqrINT and norsqrDUR, among 4 groups of measurement schemes, which normalized the Euclidean measurement. The greatest acoustical change of prosodic information influenced by emotion was shown in the values of F0 followed by duration and intensity in descending order according to the effect size based on the estimation of distance between emotional utterances and neutral counterparts. Tukey Post Hoc test revealed 4 homogeneous subsets (calm

Event-driven communication protocols such as CAN(Controller Area Network) have inherent packet delays due to the contention process for the use of network medium. These delays are stochastic in nature because most packets arrive at random time instants. The stochastic property of the delay adversely influences the control system's performance in terms of stability, responsiveness and steady-state error. Another problem for safety-critical application such as brake-by-wire systems is the reliability of the communication modules that can fail abruptly. This paper deals with two methods to overcome the above problems : (i) scheduling method that can maintain packet delays under some acceptable level, and (ii) redundancy management of communication modules that prescribes dual-redundancy modules' behavior when one of them fails.
